浅谈建筑给排水施工中的常见问题及解决(中英文互译)

Discussion on building water supply and drainage construction of commonproblems and Solutions浅谈建筑给排水施工中的常见问题及解决孙峰Abstract:Building water supply and drainage construction quality directly affects the building use function. In this paper, combined with the supervision of water supply and drainage engineering practice, for building water supply and drainage of common problems in construction were summarized and analyzed.Key words: building water supply and drainage construction qualityOur country national economy actual strength increases ceaselessly, construction industry develops rapidly, and constantly improve the level of overall construction of buildings. Construction equipment perfection degree and design level is the embodiment of building construction quality and an important symbol of modernization level, inside of the building water supply and drainage engineering is an important part of construction equipment, its technical level and advanced directly affects the using function of building, and people life, health, the environment, security. With the improvement of people's living standard, people in addition to the building safety, durability and economy have certain requirements, at the same time on the construction of the comfort, use requirements are also more attention, especially for the residential building energy saving and new energy utilization, Chuwei technology, pipeline technology, environment and security technology etc have higher requirements, these requirements in addition to the design and materials, equipment selection, construction greatly need assurance of installation quality. The quality of construction quality, directly affects the normal operation of the building water supply and drainage system. China's economic construction and development, various types of residential lots, building water supply and drainage technology of rapid development. However, with the increase of water supply and drainage engineering, also appeared some problems needed to be paid attention to, if not handled properly, will give householder brings a lot of unnecessary trouble. Therefore, the study on how to avoid water supply and drainage construction problems easy to occur is verynecessary. In the actual construction of water supply and drainage engineering construction, except in the raw materials and so on the objective factor to control the quality of water supply and sewerage works, improve employees' professional level, in strict accordance with the rules and regulations, standard operation, can be less problems, control of water supply and drainage project construction quality. Due to the level of management of construction enterprises, construction of personnel quality, building water supply and drainage construction quality is put in very big difference. Here in the construction process should pay attention to the problem is discussed:1 Living water supply systemAt present construction is widely used in aluminum-plastic composite pipe and polypropylene random copolymerization polypropylene ( PP - R ) tube. Plastic pipe has the advantages of light weight, no rust, scale, manufacturing, low energy consumption, smooth inner wall, hydraulic condition is superior, quality health, no pipeline two pollution, low labor intensity, saving installation of comprehensive construction cost advantages. PP - R water pipe connecting method is the use of fusion welding, aluminum-plastic composite pipe made of copper connection. The former applies for surface mounting, the latter applies to the dark. But there are some problems in the construction of which need special attention.(1) In the vertical tube lead-out branch tube three through parts arranged at the supporting point, the intermediate support is still in accordance with the provisions set. In the installation of pipelines should be considered in the pipeline of linear expansion, PP - R plastic water supply pipe expansion coefficient than the metal tube, wall concealed piping due to wall finally with cement mortar cement mortar filling pipeline, friction and plastic pipe special good creep effect, so that the shaft extension into radial change, therefore, block wall pipeline, can be considered linear expansion. For the pipeline, when the distance is longer, should consider adopting a telescopic device and the angle of natural compensation(2) Outdoor installed plastic water supply pipe must have reliable shading or heat preservation measures, through the pipeline settlement joints for compensating treatment. Because plastic pipe anti aging performance have certain limit, when exposed to install, long-term sun exposure can accelerate aging of plastic material, it should be considered to take effective shading or insulation measures. In addition the pipeline settlement joints shall be taken compensation measures, or easy to make pipeline rupture, appeared the phenomenonof water leakage(3)In the kitchen, Wei bovine apparatus for concentrating bathrooms, should adopt the water separator. Using plastic tube as a cold, hot water pipe concealed in floor slab of concrete in plastic pipe, due to the linear expansion coefficient of metal pipe to relatively large, because the water temperature or the ambient temperature changes, the expansion and contraction of the length change of large value. For branch pipe or pipe joint pipe, the higher chance of leakage. Water separator is a kind of multiple branch joint water distribution, it uses multiple unidirectional cloth tube, each a water distribution pipe through the water and sanitary ware and the tap connection, to reduce or cancel the concealed pipes used in branch pipe or pipe joint.(4) pipeline crossing roof slab should be set casing, through the roof should be used when the metal casing, height must meet the standard requirements. The casing and the cracks without perfusion of fine stone concrete, shall not use the asphalt in Yau Ma Tei wire packing seal. Otherwise, if the floor area of water sewage easily along the pipe wall infiltration into the submucosa.(5) the role of automatic exhaust valve. In no time delay self-closing valve of the squat toilet building water supply system, such as schools, hotels, office buildings and other force in water supply pipe system, if the top with self-closing valve can well control the flow of water, but not very good control of airflow. When the system is cut off, water pipes often accumulate a large amount of air. System after water supply pipe, air may be compressed to the tube at the top of water to form a compressed air zone. When someone is pressed delay self-closing valve button, then the compressed air with water gushing out of the closet, often within the dirt blowing to above ground, even spilled onto the clothes closet.2 Drainage system(1)The UPVC pipe wall is white, very susceptible to pollution, so the use of the process should pay attention to protection, in the pipeline in place should be promptly after the plastic packaging bag, to be removed after the completion of the project.(2) Drainage pipe out door horizontal pipe and vertical pipe connection should be used when the two45. Elbow instead of90. Elbow, which is beneficial to the drainage. There are also some engineering design for the three plus examination export method. In some projects, product quality, leading to the three links are often damaged, inconvenient repair. So in thevertical pipe and main pipe is connected with the fixed support, parts. Vertical pipe through floor roof should be fixed as supporting points, and with sheath.(3) In the legislative branch, floor, to do the protection work. For UPVC tube light weight, should be timely plugging holes in floors, planted bracket. There are a number of projects, because there was no time to fill the hole plugging holes, civil engineering, causing destruction and pipeline slope and verticality of affected. The correct approach is to stand pipe after completion of construction, straightening and planted bracket, with a good fine stone concrete plugging hole. Branch floor, planted set hanger and plugging holes. Because the floor, floor drain and the straight tube exposed to the ground, easily damaged, precautions should be taken. The specific approach is: in the floor drain and the straight tube around the100arm UPVC tube saw small short circle in the floor drain and straight around, with a fine stone concrete protection, height of not more than civil screed. For ease of maintenance, pipe water trap should be above the floor slab, for apparatus with water storing bend. Because the UPVC pipeline is light weight, thin tube wall, should pay attention to using a muffler noise reduction function fitting.(4)Installed to meet the requirements. The interior floor is mounted high above the surface, will cause the water leakage is too low, on the ground to form a pit, affect the surface clean and inconvenience in walking.(5)Air nozzle shall be located in a building ( such as eaves cornice took part, balcony and canopy ) above, otherwise cause odor accumulation. In accordance with the relevant standard requirements, the people often activity of roof, roof vent pipe extends the height of not less than 2m, and try to set bracket.(6)High-rise building in the UPVC ~ B pipe, without taking the measures to prevent fire from spreading. According to the" hard vinyl chloride building drainage pipeline engineering" ( cJJ / T29 - 98) Regulations: high-rise buildings indoor drainage pipelines that apply settings and big diameter or equal to 11Omm, in vertical pipe through the floor should be set to fire the casing or fire blocking ring, to prevent the fire spreading to the upper layer through a pipeline.(7)The floor drain and trap with. No provisions for floor drain must set up a trap, but it can affect users. The general water supply and drainage standard atlas will take seal circular bell type floor drain to a, B, C, Ding Si, although the standard of water seal section height to makespecific provision, but there is a water storage, water due to water evaporation and destroyed. Manufacture and installation and often fails to meet the design requirements. All indoor undertake a fecal sewage drainage floor drain, shall be set the trap, this can effectively prevent odor phenomenon.(8) Sewage emergency discharge tube. For kitchen and toilet adjacent residential, kitchen, toilet is if separate drainage system, is straight at the bottom of two system for emergency discharge unicom. The correct approach is to lead a floor drain from the kitchen and toilet pipe or by a toilet to kitchen pipe system. Its purpose is to once - side discharge pipe suddenly jam, still discharge sewage overflows when the ground floor drain into another system from the outside, but not to the other indoor room large area sewage soaks inundates.3 Fire water supply system(1) The design of automatic sprinkler system for pipeline connection made the trench should be used to clamp connections, or wire joint, flange connection. The current widespread use of the automatic sprinkler system, generally with galvanized steel pipe galvanized pipe, and larger in diameter than the5Omm, pipe parts of poor quality, construction difficulty. Diameter of1OOmm welding work, will destroy the galvanized layer, causing the two galvanized, the effect is not ideal. As the hoop connection parts, to avoid the above problem, and the construction is simple, without welding, and the grooves can be precast. Now the groove type clamps connecting piece is stereotypes products, mature technology, spare parts complete, quality assurance. When the proposed pipeline diameter is larger than 50mm, the groove type clamps connecting piece.(2) As the applicator interface diameter is 15mm, so some construction spaces using15ram galvanized steel pipe small vertical tube connected with the nozzle, effects of fire extinguishing water ability, should adopt the25mm diameter pipe with different diameter pipe hoop. Some engineering support, support installation is not standardized, not according to the specified distance setting, defenseless and Akira bracket, directly affect water effect, should be strictly in accordance with the relevant standard, set Branch hanger.(3) Network to carry out maintenance and leakage test of strength test is performed in two steps. Some construction unit only to the network leakage test or test the pressure does not meet the requirements of design and codes, this will give the normal operation of the system brings hidden trouble.(4) Banned the use of plastic water supply pipe for fire water supply pipe, or in a building plastic water supply pipeline and fire water supply pipeline. Because plastic pipe heating after reduced intensity, fire will cause the pipeline damage, will not play the role of fire water supply. Plastic water supply pipe and fire pipes, fire, damage to the plastic pipe, easy leakage, there is no guarantee that a fire water and hydraulic pressure.(5) Must be in conformity with the requirements of fire hydrant installation. Some concealed in brick wall of fire hydrant boxes above the hole without lintel, by loading body is deformed, causing the box door is open. In addition the construction of some units to randomly change the fire hydrant at the end position of a preformed hole, and welding and cutting hole, leading to the installation, hydrant mouth can not be with the wall into 45or 90degree angle; or with the surrounding distance is too small, causing the fire hose cannot be installed to a fire hydrant or the tape to form bending effect of water.4 Water supply and drainage noise solutionIn addition to the requirements of water supply and drainage pipe and equipment layout should be consistent and building structure, water supply and drainage noise reduction. During construction, attention to details, can effectively reduce the noise generation.(1) In order to reduce the water hammer occurrence possibility, the outlet valve Shuizui and not using the rapid opening and closing of the water supply fittings.(2) In order to reduce the flow induced vibration noise, according to the condition of the water supply pipe and selection of density of sanitary ware, and according to the standard setting of pipe support and hanger. Different pipes with different support spacing requirements; design pipeline fixing bracket, also should consider from pipeline temperature changes caused by the expansion and contraction force.(3) To reduce the cavitation noise of ascending and descending pipe, for heating system of water distribution pipe top and to elevation of the pipe section should be equipped with automatic exhaust valve; downfeed system can use the highest water distribution point when a branch is deflated splitting meter, in the water vertical tube top with automatic exhaust valve.(4) Drainage system reduces the vertical pipe and horizontal branch connection angle, or a branch connecting the upper part special parts, reduce the horizontal branch pipe to water flow, to avoid the water jump phenomenon, thereby reducing the drainage noise.(5) Drainage pipe and drainage standpipe connection should be45 degrees,60 degreeselbow, three links, or set up a special accessories. Connections of the elbow should be composed of 2to 45 degrees elbow, and shall be on the elbows set supporting pier or bracket. In this way, can slow down the drain pipe and the drain pipe of the water flow in the water flow and vertical draining pipe wall impact noise.(6) To increase the horizontal trunk pipe and vertical pipe and horizontal trunk pipe connecting bend radius of curvature, or installed with reduced height of hydraulic jump, stable drainage pipe pressure function lower special accessories, to improve the horizontal trunk pipe drainage condition.5 Conclusion:Living, live as the mankind indispensable material conditions, is restricted by social productivity, at the same time, is also the social productivity development level indicates one of. From the initial human ancestor looking for natural caves and trees do sacrifice body are today a multi-storey and high-rise residential buildings and supporting a full range of public facilities of residential area, residential construction technology, marked the social productive forces to a new level. Today, our life has stridden to well-off, residential construction quality, indoor and outdoor environment improvement, so that our country's housing situation in recent years have varying degrees of change. In residential construction, although our country starts later, but the government has pledged, formulate corresponding policies, government departments to organize and mobilize all aspects involved in residential development plan, planning, design, construction and management. No doubt, this is a huge task, need government, the construction industry and the vast majority of the practitioners, down-to-earth to make unremitting efforts. Upgrade and improvement of our people 's living environment and living conditions. With the water supply and drainage pipe of continuous improvement, we should constantly sum up the design and installation of the experience lesson in the process, improve the general level of the installation. Professional supervision engineer shall be in this play a greater role in the. In the new century, building water supply and drainage will shoulder the historical responsibility, facing new challenges. Building water supply and drainage will be more prominent in the people-oriented principle, and will focus on the adjustment to the civil and industrial construction to pay equal attention to both, public buildings and residential buildings, water supply and water supply and water, water pressure, and water quality to pay equal attention to, direction, into a comprehensive, balanced,practical, safe development road.References[1] Li Wenqing, Shao Zhuang.

多层住宅建筑给排水设计常见问题

多层住宅建筑给排水设计常见问题1、给排水管道敷设问题设计人员应改变上一层的卫生间管道在下一层楼板安装的旧做法;倡导本层的管道在本层越江输油管的原则(规范):1)卫生间统合做成下沉式卫生间,按过去的老做法把下水管道统一布置在地坑内;2)卫生间地板两面不下沉,而使用后出水式坐便器,地漏采用侧墙式,洗脸盆、浴缸等喉管排水管道在地面以上敷设并与立管相接,厨房取消地漏或用侧墙式地漏,把洗菜池的排水管放在地面接入立管,这样做做可以使下水管道每层水平发展水平分隔开,如有漏水下陷则不影响下层住户,检修时也可以独户进行。
另外,建物设计时尽量把排水管立管设于建筑物内墙阴角,有条件的最好在卫生间内设置管道井。
这样做可以使室内卫生间、厨房水平与没有竖向均没有明管,空间宽敞、洁净,把污染源———污水隔绝在外,避免由于管道频繁穿越楼板引起上下层漏水的现象。
1.1给排水立管的敷设1)立管安装在厨房、卫生间的墙角处。
在以往的住宅设计中较多采用这种敷设方式,施工方便,但明露管道有碍居室美观,住户在二次装修铝制时大多会用轻质材料将其隐藏起来。
管道明装在室内时,应不影响厨房、卫生间各卫生设备功能的添加。
2)立管敷设在管道井内会。
这种型式居室洁净美观,但管道井挤占了卫生间的面积,且管道施工、维修较困难。
卫生间设立集中管道井,把给水管、排水管等管道都高度集中在管道井里布置,这是现代住宅厨房居住文明的重要体现。
1.2给水支管敷设1)一般住宅给水支管管路de≤40mm或dn≤32mm,小管径的塑料给水管呈弯曲状态,且热稳定性差,故住宅给水支管提倡改采埋墙暗设。
2)支管设在砖墙里。
施工时在外立面面开管槽,管槽宽度为管子外径de+20mm,深度为管子外径de;改采金属管件连接时,需加大管槽尺寸;管线直接嵌入管槽,并用管卡固定在管槽内。
3)小管径给水支管de≤20mm,可暗设在楼(地)面找平层里。
施工时在楼(地)板面上开管槽,槽宽为de+10mm,深为0.5de,管道细歧须嵌入管槽里,并用管卡顶板将管子固定在管槽内。

关键词:多层建筑;室内给排水设计;消防给水Abstract: water supply and drainage designer should with overall design ideas and methods to comprehensive consideration of the indoor water supply and drainage design, make indoor water supply and drainage design to scientific, economic, beautiful wait for effect. This paper discusses the multi-storey building indoor water supply and drainage design.Keywords: multi-storey building; Indoor water supply and drainage design; The fire water system多层住宅大部分使用UPVC塑料排水管,室内UPVC排水管的类型有普通UPVC实壁管、UPVC芯层发泡管(PSP管)、UPVC螺旋消音管三种。
普通UPVC实壁管噪音较大,而同等壁厚的UPVC芯层发泡排水管比UPVC实壁管重量轻约20%~30%左右,同时它又具有隔热隔音的效果,特别适合于建筑排水,可显著地降低流水噪音,大有取代UPVC实壁排水管的趋势。
UPVC螺旋消音管不仅可以降低噪音,而且与其它同管径排水管相比排水能力大大提高。
二、排水塑料管道的降噪方法目前排水管道普遍使用塑料管道,但是普通U P V C 管道的排水噪音要比铸铁管高,若排水立管靠近卧室,加上现浇楼板的隔音效果较差,住户能明显感觉到排水管道的噪音,降低了生活质量。

外文资料翻译On setting the metersetting the meter. Long-term since, our country residence water meter are arranged on the indoor kitchen or toilet water concentration, the water more and scattered residences, sometimes even a indoor set more than one meter. In recent years, water meter is arranged on the indoor and caused many problems cause the attention of people increasingly: Home meter reading disturbs people 's normal life and may lead to residential burglary, privacy and safety not guaranteed: management of meter reading meter reading is not easy and large labor intensity: individual user steals water management departments to prevent and punish and so on. Because of these problems, water production has become an inevitable choice. Therefore, the newly revised national standard ( code for design of building water supply"GBJ15--88article 2.5.8: residential building should be installed in household water meter, household water meter or household water meter digital display should be located outdoors. Meter households generally have the following ways: Household water meter concentrated in the roof ( water supply ) or the underlying space ( water supply ). This mode is often used for multi-stormy residential. In general a unit provided with a ladder of water meter water meter well ( box ), household water pipe along the interior tube or building wall into the indoor. The utility model has the advantages of convenient reading; reading, low labor intensity of workers, can avoid users water behavior. Disadvantages are: material consumption, head loss of pipeline, occupying larger space pipeline well, such as a wall is easy to affect the appearance of the building, the user branches not easy maintenance.Meter is arranged on the stair landing platform. Vertical water supply pipe is arranged on the platform, each provided with a water tank; the water meter box embedded platform resting on both sides of the wall. The utility model has the advantages of: user branches short, saving material, low head loss of pipeline, the shortcoming is: water dispersed settings, meter reading personnel of great labor intensity; usually indoor fire hydrant box is installed on a platform, so that the already crowded rest platform more cramped, traffic inconvenience to the residents.Each layer isMeter centralized meter room, household water meter on the wall. The utility model has the advantages of the same with B, the disadvantages are: household pipeline must follow the public walkway under floor into interior and corridors, ceiling requirements.Will be the traditional ordinary mechanical water meter changes for telemetering water meter or IC card intelligent water meter. Remote water meter accurate calculation without reading, this form must be a deposit a certain amount of water, will recharge after insertion of the IC card water meter reading can be water. Because the remote water meter and IC card table relatively expensive and technically still exist certain problems, hence in practice has not been widely applied.Above a few kinds of water-meter, each has its advantages and disadvantages, concrete in practical engineering design in which way, by the design staff according to residential properties, grades and local industry management department requirement.1.2water supply pipe arrangement and laying. At present, to build the house in one hutch two defend very general already, even with some houses one hutch three defend one hutch four defend, kitchen, toilet, the balcony, and each water using point locations are more dispersed. User branches to water points along the interior floor pipeline such as hanging, inevitable requirement set indoor ceiling, wall should also have the anti-condensation measures to bring inconvenience, household decoration, after all, not all tenants wanted to ceiling. ( the building water supply and drainage design specification ) GB15 2000(manuscript ) as specified in article 3.6.18, water supply pipe should be laid in the floor ( ground ) surface of the leveling layer or along the wall laying pipe groove, laying the leveling layer or the tube groove water supplying pipe outside diameter is less than 25mm. In fact, if connected to two or more than two water points, water supply branch pipe are connected together in series, the pipe diameter is more than 25mm. Therefore, in order to meet the specification requirements, water supply branch door after access water separator, a water segregator dark kitchen or bathroom wall, through the diversion device connected to each water using point branch pipe diameter can be controlled under 25mm. But it should be noted: a leveling layer water supply pipe after completion of construction, should be in the position to do the obvious markers, lest the household decoration, destruction of water supply pipeline.水表设置关于水表设置。

The multilevel residential housing is given and drains off water severalquestions designedSummary : This text give and drain off water on multilevel residential housing design supply water the exertion of the tubular product , Way of laying of pipeline, water gauge produce family set up, establishment and air conditioner condensation water of pot-type boiler discharge issue goes on the discussion , And put forward some concrete views.Keyword: Skyscraper, supply water the tubular product , the pipeline is laid, The water gauge, the solar water heaterThe skyscraper is simple with its auxiliary facility, the fabrication cost is low, the characteristic such as being convenient of estate management, Receive the welcomes of the real estate developer and vast resident of small and medium-sized cities very much. How project planning and design of inhabited region, scientific and technological industry of comfortable house, lead the request according to 2000, Improve the design level of the house, build out a comfortable living space for each household, It is each designers duty. As the heart of the house --The kitchen, bathroom, is that the function is complicated, hygiene, safe and comfortable degree are expected much, It is miscellaneous to build, the space expecting much in technology. So, the designer must consider synthetically with the idea and method of global design that the kitchen, bathroom give installation of the drainage pipeline and equipment,etc. . Give and drain off water on skyscraper design supply water exertion, to lay pipeline of tubular product, water gauge produce family set up, establishment and empty of pot-type boiler now Transfer condensation water discharge issue discuss together with colleagues.( 1)supply water tubular product select problem for use Traditional watersupply tubular product adopt zinc-plated steel tube generally, because zinc-plated steel tube exchange the corrosion, Use short-lived , use for and send domestic water can satisfied with water quality sanitary standard shortcoming, Ministry of Construction is popularizing the application of the feed pipe of plastics energetically . A lot of districts and cities have already expressed regulations: Forbid designing and using the zinc-plated steel tube , use widely the feed pipe of plastics. The plastics supply water In charge of compared with metal pipeline, light, it is fine to able to bear the intensity of keeping, Send obstruction little liquid , able to bear chemistry better to corrode performance, it is convenient to install, The steel energy-conservation of the province, merit of having long performance life etc.. Supply water and use plastics pipeline: Hard polyvinylchloride( PVC-U), high density polyethylene( HDPE), pay and unite polyethylene( PEX) , modify the polypropylene( PP-R, PP-C), gather butene( PB), aluminium mould and compound and in charge of and the steel is moulded and compound and is managed etc.. Choice of tubular product economic comparative course of technology, technology should from pressure, temperature, environment for use, install method,etc. go on and consider, Combine owners at the same time request and the house of grade,carry on and fix after being consider synthetically technology not economic. The above plastics supply water tubular product can supply water tubular product as house life. The economic and functional house conciliating Strand room in the face of the masses of with low- and medium-level incomes resident, can select for use hygiene grades of hard polyvinyl chloride in charge of as feed pipe mainly, In order to reduce the fabrication cost; Medium-to-high grade commodity apartment available aluminium Mould and compound and in charge of or other plastics supply water the tubular product as the feed pipe. House mix hot water temperature that water order exceed 600 C, so above-mentioned tubular product in charge of except hard polyvinyl chloride and aluminium plastics compound and in charge of( PE-AL-PE), Mostly the tubular product can be regarded as the hot water pipeline of the house.( 2) pipeline lay problem 1. give and drain off water it set up there arent one that in charge of(1)Will install it in the corner place of the kitchen, bathroom tomorrow. Adopting this kind of way of laying more in the design of house in the past, it is convenient for it to construct, But will reveal the pipeline and hinder the room beautifully tomorrow Watch, the households will mostly be hidden with the light quality material in the equipment two times.(2)Will install it in the overcast angle place of the outer wall of the building tomorrow. Way this suitable for southern weather warm district only, the minimum temperature in winter cant be lower than zero degrees Centigrade, In case water pipe water-logging freeze ice is bloated to split pipeline, influence household use. Pipeline lay in outer wall, influence building to be beautiful, too inconvenient on manage and maintain in the future.(3)Lay it in the pipeline well. This way makes the room clean and beautiful , but the pipeline well has taken up the area of the bathroom, And pipeline construct, maintain relatively more difficult. Bathroom set up concentrate pipeline well, concentrate pipeline on assign in the well feed pipe, drain pipe, This is that the civilized importance lives in the kitchen of comfortable house, bathroom Embodiment. I think : Should consider the establishment of the pipeline well of the bathroom in the medium-to-high grade building conceptual design of commodity apartment, Improve quality of using of bathroom promptly so , can solve hard polyvinyl chloride drain pipe rivers noise heavy problem, Improve the environmental quality level of the room; Whether for bathroom in the areas for little economic and functional house and Overcome difficulties room, warm area give and drain off water and set up and in charge of and can consider and lay in the outer wall in the South, In order to increase using the space of the bathroom; Pipeline install and in the room, should influence kitchen, bathroom every sanitary equipment use of function tomorrowsupply water and prop up there arent tube House supply water prop up and in charge of pipe diameter one ≤ 32mm, de of battle,, little plastics feed pipe of pipe diameter is the crooked state, So the house supplies water and is propped up and in charge of being recommended and adopted and set up secretly. Supply water to prop up to manage darkly There are thes way had:(1)Set up in the brick wall secretly. Wall turn on and in charge of trough in brick when constructing, in charge of trough width tube +20 mm, de of external diameter,, degree of depth tube external diameter de, The pipeline is imbedded and managed directly Trough, and with in charge of card fix in trough of inning charge of son.(2)Whether pipe diameter supply water and prop up and last de ≤ 20mm,can set up at floor secretly piece make level by layer. Turn on and in charge of trough in floor( ground) the board when constructing, it wides trough have to be de +10 mm deeply 1/2 of the de, Half pipeline imbed and in charge of trough, and with in charge of card fix in trough of inning charge of tube. Aluminium mould compound and in charge of and pay and unite polypropylene in charge of pipeline adopt metal pipe fittings connection, Must strengthen and in charge of trough size when adopting and set up secretly, and rivers some flood peak loss relatively heavy. Assign the relative house that concentrated to the kitchen, bathroom interior hygiene utensil, Can adopt and divide Water device go on and join , divide water device whether one more than branch in charge of and connect, every hygiene utensil supply water and prop up and in charge of and connects and publishes from the water dividing device separately. Can already prevent the tube burying the pipeline secretly from being connected like this Permeate the question. Can reduce some flood peak lost, decrease the fabrication cost of pipe networks(3)Drain off water and prop up the tube to lay House room drain off water and in charge of and should set up at the time of inning this each, drain off water and in charge of permeating sideways like this canning prevent the sewage from waiting for the pollutant to enter the neighbor family sideways, Will not influence the neighbor either when the pipeline is maintained Normal life of one. Kitchen wash water drainage of basin propped up and in charge of generallying inserts draining off water to stand to managethis layer of floor sideways; Floor drain drain off water propped up and in charge of laying the room of lower floor. A lot of colleagues think now: Whether kitchen the ground it lay ceramic tile of,whose name is clean in when need develop with water,not strong in meaning to set up floor drain, So kitchen set up ground floor drain, avoid and drain off water and prop up and in charge of and enter neighbor family sideways already so, Can increase using the space of the kitchen . Bathroom drain off water and prop up and in charge of and lay concrete measure have in this layer sideways inside:(1)Improve the bathroom ground . Ground tendency high 150mm, adopt back row type take stool pot, washing basin, bath tub, water drainage of floor drain in charge of and bury in cushion layer secretly sideways.(2)Adopt the sinking type bathroom. Bathroom sink 350mm the floor, hygiene utensil drain off water and in charge of and bury on sinking space secretly sidewaysTwo method these can realize water drainage of bathroom prop up and in charge of earths surface to bury underground this one without entering the neighbor family sideways. Bury pipeline when installing, construction quality must check on strictly, can construct bathroom ground after confirming qualified secretly, So as not to leave the hidden danger in giving in the future using. Bathroom ground construct and can pack coal ash light quality material , also can adopt and lay bricks impracticable to lay plate making construct ground, Ground must make waterproof to deal with, method can waterproof to deal with according to roofing, make two oil one rubber and plastic ointment waterproof cloth.(3) water gauge the open air set up problem The water gauge is had indoors, not only the work load of checking meter is very heavy , but also make the security and privacy of the house reduce greatly . So house divide into households of water gauge or divide households of figure of water gauge Show that should be set up in the open air. Skyscraper water gauge the open air set up following several kinds of forms: Whether 1.adopt far it pass by water gauge Change the ordinary water gauge into and pass the water gauge far, is joined the water gauge and data gathering machine by a signal line, And then reach intelligence to manage( the computer). Its merit lies in saving a large amount of people Strength comes to check meter, the data are accurate, the shortcoming is that the fabrication cost is high. Whether 2.adopt magnetic stripe card of by water gauge Users buy the electronic card of the running water Company in advance , then insert it in the storing device of the water gauge, Card amount of money deduct automatically on the water, this way user need to prepay the water rate, The price of the water gauge is relatively high.adopt it set up at the open air water gauge not ordinary(1)The water gauge is set up in the stair have a rest in the alcove of the platform. Household watersupply to prop up and manage and enter the kitchen, bathroom after the water gauge is measured. Way this realize water gauge produce room set up, equivalence low project have , supply water and set up and in charge of and set up with water gauge office results in aesthetic problems in stair. It suitable for the South warm district kitchen, bathroom assign close to the houses of positions of staircase.(2)The water gauge concentrates on being set up among the water gauges( meter box). Person who give when supplying water, set up water gauge in ground floor( meter box) on falling, every household watersupply to prop up and is in charge of applying having in the pipeline well, Southern area can overcast horn place lay along the outer wall in building too; Person who give when supplying water, can set up water gauge in roof( meter box) under upgoing. This way increases and supplies water to prop up In charge of and lay length, pipeline lay and influence building to be beautiful along outer wall. Water gauge produce way choice that family assign, must combine house kitchen, bathroom plane assign characteristic and concrete request of developer, Carry on to several feasibility scheme the above economic technology fix after comparing. Property well-managed medium-to-high grade commodity apartment of housing district, can adopt and pass the water gauge far , It is that the water gauge will use the developing direction in thefuture; Estate management perfect medium- to-high grade commodity apartment of housing district, can adopt magnetic stripe card water gauge( Company have this kind district of business can design in running water) Or concentrate on setting up it among the water gauges( case); Southern area unit type house can set up rest platform office in stair with ordinary water gauge, In order to reduce the fabrication cost.(4) establishment question of the pot-type boiler Should reserve and install hot water supply terms of facility, set up hot water supply facilities with when the design of house. Have and concentrate house that hot water supply on , should consider house assign with installation position and cold hot water pipeline of hot water device. The pot-type boiler generally has three kinds, such as gas, electricity, solar energy,etc.. Whether last kitchen gas heater and electric heater or Bathroom inside, give when draining off water design shoulding reserve installation position and cold hot water interface of pipeline of water heater in advance in building, Install by oneself when convenient users fit up. Solar energy and hot water It is simple and convenient and safe for device to use, need fuel and electric power is low to run the expenses, Have long performance life, pollution-free, received by the masses of users favourably very much, Many houses have been small in recent years The district all install the solar water heater at the time of designing and construct. Solar water heater install and at the roof, need to set up the cold hot water pipeline among bathroom and water heater of the roofing like this generally, Consider installation of solar water heater when the design of house, household can only lay cold and hot pipeline along the building outer wall when installing in the future, Increase household degree of difficulty when installing like this , increase pipeline make the investment, influence building beautiful. Give when draining off water the design needing to solicit the developers suggestion first in building, Interconnected system one design, construct the solar water heater in unison; Reserve solar water heater and cold hot water installation position of pipeline in advance only. The cold hot water pipeline of the solar water heater can be laid In the pipeline well; Set up pipeline house of well , can set up one UPVC drain pipe of de110 as solar water heater hot water sleeve pipe of pipeline close to corner of person who take a shower in bathroom, Set up a de110 *75 three direct links in each hygiene interval ground, as connecting the entry of cold and hot water pipe ( 5) air conditioner condensation ink discharge the issue In recent years, air conditioner enter huge numbers of families gradually, condensation water amorphous to discharge the building outer wall of pollution air conditioner have, Have influenced a beautiful important problem of biotope already. Building give when draining off water design shoulding consider air conditioner condensation ink discharge in a organized way. Concrete method can machine set up the water drain pipe of the condensation by the position outside reserving air conditioner, Drain off water and set up and in charge of and select PVC-U drain pipe de40 for use , reserve three direct links of draining off water highly in each air conditioner, It is convenient for air conditioner to drain off water hose insert directly.译文:多层住宅建筑给排水设计的几个问题多层住宅以其配套设施简单,造价低,物业管理方便等特点,很受中小城市房地产开发商和广大居民的欢迎。
