奈普顿化学泥浆的作用和管理

奈普顿化学泥浆的作用与管理在基础工程中护壁是旋挖钻机施工的一项重要技术,在钻进过程中,根据实际钻进的地层情况,科学的选用合适的泥浆类型进行冲洗钻孔。
以便达到清楚孔底岩粉、冷却钻头、润滑钻具、保护孔壁、提高钻进效率的目的。
化学泥浆在煤田地质勘探和其他行业起到的作用和各方面对化学泥浆的严格要求,促进化学泥浆技术取得了迅速的发展。
经过多年的科研开发和生产实践,化学泥浆已从仅满足钻头钻进发展到适应各方面需求的化学泥浆体系。
例如:为快速钻进服务的低粘度、低摩擦、低固相的聚合物化学泥浆。
防卡化学泥浆、针对岩石特点的防塌化学泥浆、钻盐岩层的饱和盐水化学泥浆等,形成较为完整的化学泥浆体系。
如今优质的化学泥浆已不是一两种材料(例如膨润土、烧碱)配制的,保持化学泥浆的性能要依靠加入各种处理剂。
优质的奈普顿化学泥浆能提高钻头寿命、减少提钻次数、缩短旋挖施工周期、降低旋挖施工成本、提高旋挖施工效率,还具有制备容易、成本低、用量少的优点。
一、泥浆的功能泥浆又叫做化学泥浆或聚合物泥浆,被比喻为旋挖施工的血液。
泥浆停止循环,旋挖施工工作就不能正常进行。
1、冲洗孔底:泥浆可在钻头水眼处形成高速的液流,喷向井底。
这高速喷出的泥浆可将由泥浆压力与地层压力差而被压持在井底的岩屑冲起,起冲洗孔底的作用。
2、携带岩屑:当泥浆在环空的上返速度大于岩屑沉降速度时,泥浆可将岩屑带出,即在一定的上返速度下,泥浆有携带岩屑的作用。
3、平衡地层压力:泥浆的液柱压力必须与地层压力相平衡才能达到防止井喷或者泥浆大量漏进地层的目的。
可通过调整泥浆的密度控制泥浆的液柱压力,使它与地层压力相平衡,起到防涌堵漏的作用。
4、冷却润滑钻头:泥浆可将旋挖施工过程中钻具(钻头与钻柱)与地层摩擦产生的热量带至地面,起冷却作用。
同时,泥浆能有效地降低钻具与地层的摩擦,起润滑作用。
5、稳定井壁:可在泥浆中加入适量的处理剂,使泥浆具有抑制页岩膨胀或分散的能力,同时产生薄而韧的滤饼,起到稳定井壁的作用。

旋挖钻机施工具有成孔质量好、速度快,无噪音、污染小等优势。
但是,由于旋挖成孔施工无循环造浆功能,只能采用静态泥浆稳定液护壁,靠不停的向孔内进行补浆来保证孔内外水压的平衡和护壁效果,所以泥浆的选用及性能指标在成孔过程中显得尤为重要。
本工程选用奈普顿聚合物泥浆(泥浆粉)技术,它使用简单,小巧轻便,制浆速度快,护壁效果好,沉淀凝聚速度快,无污染,在泥浆制备中具有广泛的应用前景。
2.特点奈普顿聚合物泥浆(泥浆粉)是一种先进的国外技术的进口产品,是一种水溶性、易混合的粉末颗粒高分子聚合物,在水中充分溶解后成半透明糊状,粘度大。
它具有如下特点:2.1 由于聚合物泥浆(泥浆粉)分子量一般高达2800万以上,水解后分子链扩散并会与其他分子链重新连接,故会形成较为粘稠的近似糊状的泥浆,能够最大限度的粘住并快速沉淀钻屑。
2.2 在孔内由于钻具连续运动,聚合物泥浆(泥浆粉)和水混合的越均匀粘度就越强,凝聚力也就越快。
2.3 该泥浆体系能对孔壁提供压力,防止在不稳定地层中钻孔的坍塌2.4 最大化旋挖钻的装载能力,提高掘进速度。
2.5 聚合物泥浆(泥浆粉)对钢筋机械性能无影响,某品牌聚合物泥浆(泥浆粉)试验数据如下:试验项目:钢筋机械性能溶液:0.05%聚合物溶液试验结果:试验结论:依据GB/T228-2002标准,奈普顿聚合物泥浆(泥浆粉)对钢筋机械性能无影响。

Remove all grease, oil, dirt, curing compounds, sealers, adhesives or any other contaminant that would prevent a good bond. Glossy or painted surfaces must be sanded, or abraded, and stripped of all contaminants. Concrete must be cured 28 days and accept water penetration. Concrete must be free of efflorescence and not subject to hydrostatic pressure. Concrete slabs should have a coarse finish to enhance the bond. Plywood flooring including those under resilient flooring must be structurally sound and meet all ANSI and deflection requirements. For questions about proper subfloor installation, call Technical Services. Smooth concrete surfaces, existing glazed tile, terrazzo, or polished stone should be scarified. Sheet vinyl must be well bonded and stripped of old finish. Roughen the surface by sanding or abrading, then rinse and allow to dry. Expansion joints should never be bridged with setting material. Do not sand flooring materials containing asbestos. Ambient temperature should be maintained above 50° F (10° C) or below 100° F (38° C) for 72 hours to achieve proper bond.Bonding to Concrete SurfacesConcrete or plaster must be fully cured and must accept water penetration. Test by sprinkling water on various areas of the substrate. If water penetrates, then a good bond can be achieved; if water beads, surface contaminants are present, and loss of adhesion may occur. Contaminants should be mechanically removed before installation. Concrete must be free of efflorescence and not subject to hydrostatic pressure. Concrete slabs should have a coarse finish to enhance the bond. Smooth concrete slabs must be mechanically abraded to achieve proper bond.Bonding to Lightweight Cement and Gypsum SurfacesLightweight or gypsum based underlayments must obtain a minimum 2000 psi (13.8 MP) compressive strength. The underlayment must be sufficiently dry and properly cured to the manufacturer’s specifications for permanent, non-moisture permeable coverings. Surfaces to be tiled must be structurally sound and subject to deflection not to exceed the current ANSI Standards. Surfaces shall be free of all grease, oil, dirt, dust, curing compounds, waxes, sealers, efflorescence, or any other foreign matter.All Lightweight cement or Gypsum surfaces should be primed with a properly applied sealer or a primer coat of RedGard, consisting of 1 part RedGard diluted with 4 parts clean, cool water. Mix in a clean bucket at low speed to obtain a lump free solution. The primer can be brushed, rolled or sprayed to achieve an even coat. Apply the primer coat to the floor at a rate of 300 sq. ft.l (7.5 sq. m/L). Drying time depends on site conditions, but is normally less than 1 hour. Extremely porous surfaces may require 2 coats. At this point, RedGard can be applied to the primed lightweight or gypsum based surface. Refer to the individual product data sheet or packaging directions for application instructions. Expansion joints must be installed in accordance with local building codes and ANSI/TCNA guidelines. Refer to TCNA EJ171.Bonding to Plywood SurfacesPlywood floors, including those under resilient flooring, must be structurally sound and must meet all ANSI A108.01 Part 3.4 requirements. Maximum allowable deflection: L/360 tile L/720 stone. See TCNA F150-13 Tile Installations, TCNA F141-13 and F250-13 for Stone. For questions about proper subfloor installation requirements, call Custom technical services.Bonding to BackerboardsAs an alternative to an additional layer of plywood, WonderBoard backerboard may be installed over plywood subfloors for ceramic tile installations. Refer to TCNA F144-13 tile installations, TCNA F250-13 stone installations. Call Custom technical services when installing natural stone over plywood subfloor.Bonding to Existing Surfacing MaterialExisting Ceramic Tile, Resilient Flooring or Plastic Laminates: Resilient flooring or plastic laminates must be well bonded, as well as clean and free of all contaminates. Roughen the surface by sanding or scarifying; rinse and allow to dry. Do not sand flooring that contains asbestos. For existing well bonded ceramic tile, mechanically abrade the surface. Rinse and allow to dry. When sanding, an approved respirator should be used.Bonding to Cutback AdhesiveAdhesive layers must be removed, as they reduce mortar bond strength to cement surfaces. Use extreme caution; adhesives may contain asbestos fibers. Do not sand or grind adhesive residue, as harmful dust may result. Never use adhesive removers or solvents, as they soften the adhesive and may cause it to penetrate into the concrete. Adhesive residue must be wet scraped to the finished surface of the concrete, leaving only the transparent staining from the glue. To determine desirable results, do a test bond area before starting. Refer to the RFCI Pamphlet, "Recommended Work Practices for Removal of Resilient Floor Coverings" for further information.Movement Joint PlacementExpansion joints and cold joints, as described in ANSI A108.01, should never be bridged with setting material. They must be brought through the tile work and filled with an appropriate elastomeric sealant. Contact Custom® Building Products for the proper treatment of control or saw cut joints. Refer to TCNA F125, F125A and TCNA EJ171. Mixing RatiosMix 5 qts (4.73 L) clean water per 50 lb (22.68 kg) bag of mortar.Mixing ProceduresMix by hand or use a low 150 – 200 rpm speed 1/2" (13 mm) drill to achieve a smooth, paste-like consistency. Let the mixture slake or stand 5 – 10 minutes; stir again and use. Stir occasionally, but do not add more water. When properly mixed, troweled ridges will stand without slump.Application of ProductInstallation must conform to ANSI A108.5. Use a properly-sized notch trowel to ensure proper coverage under tiles. Using the flat side of the trowel, apply a skim coat of mortar to the surface. With the notch side of the trowel held at a 45° angle, apply additional mortar to thesurface, combing in one direction. Press the tile firmly into place in a perpendicular motion across ridges, moving back and forth. Theperpendicular motion flattens ridges and closes valleys, allowingmaximum coverage. With some tile, back-buttering is advisable.Adjust the tile promptly and beat it in with a beating block and rubber mallet. Mortar can be applied up to 1/4" (6 mm) thick after beat in. For thicker applications, use a medium bed mortar; periodically pull up a tile and check the back to ensure proper adhesive coverage. If thematerial has skinned over (not sticky to the touch), recomb with the notch trowel; if too dry, remove and replace the dry material with fresh material.Curing of ProductCuring time is affected by ambient and surface temperatures andhumidity. Use the following as a guideline. Allow 24 hours beforegrouting and light traffic. Allow 7-10 days before heavy or vehiculartraffic. Before exposure to heavy or vehicular traffic, assure assembly is rated “Heavy or Extra Heavy” per TCNA Service Requirements. As necessary, use plywood or other load distributing protection whenmoving heavy equipment across tiled assembly.

在8-10之间,用空压机搅拌均匀(搅拌时间为10-20分钟)。
3、将循环泵打开,进行自循环后,通过泵出水管口加入本产品,要求慢慢均匀加入,一般
沙层加量为万分之二点五(既100方水中加入本产品25公斤),后用空压机搅拌一小时,用工程漏斗测定溶液的黏度到30秒左右即可满足一般工程地质。
(一般情况下手感稍有粘度起线丝状即可,特殊地质根据实际情况而定)。
4、若黏度高于30秒,可直接加水稀释:若黏度小于30秒,可能是由于搅拌时间不够,需
延长搅拌时间,如果仍达不到黏度,可打开循环泵自循环后通过出水口补充本产品,并再用空压机搅拌一小时左右,直至满足条件。
5、在钻进过程中,如果含砂层较多,要提前准备好足够量的泥浆,并在钻进过程中不断补
充泥浆,保持钻进液面,确保地层压力平衡。
6、钻进完成后,停15-40分钟后,(根据孔深决定时间)用钻机打捞一次沉降下去的砂子等
杂质,不要控浆。
然后下放钢筋笼和混凝土导管,一般情况下都能达到灌注桩要求的含砂量和沉砂量,个别地层可能会出现沉砂量较多的情况,就可以在下钢筋笼之前多捞两次,以确保下完钢筋笼和导管后沉渣达标。
7、灌桩完后,返回的泥浆需要求其黏度,如果黏度低于30秒,可以打开循环泵自循环后
通过出水口补充本产品,并用空压机不停搅拌,直至满足条件。
同时,在另外一个泥浆池中配制新的泥浆,以满足下一个桩钻孔所用。
三、用量
一般情况下比例按0.01%~0.1%配制,根据现场实地情况试验确定配合比例。
四、注意事项:
1、在挖池过程中,尽量保证其大小的准确性,以保证配浆的准确性,避免浪费。
2、在配碱过程中,一定要先把氢氧化纳配制成20%水溶液,切记直接把固体氢氧化纳直接
加入泥浆池中,以便充分溶解。
3、在上层钻进过程中,正常情况下,泥浆的黏度可以小一些,大概28秒左右就可以使用,
如果上层过早出现沙层,尽量不要降低泥浆黏度。
4、在一个泥浆池一次配浆不要过多,否则不利于搅拌,在配浆的时候,要留出充足时间,
使产品充分溶解,可以达到节约成本的目的,不得在没有完全溶解的情况下使用。
5、在钻进过程中,保持液面很关键,一般情况下,要求液面不低于护筒的1/2高度处,在
钻进完成后,下钢筋笼和导管的时候也要保护液面,就是说要提前配制好足够的泥浆量。
下钢筋笼时避免碰撞孔壁
6、在下钢筋笼的时候,尽量保证操作规范,减少和桩眼四壁接触,以保证沉砂达到灌注桩
的标准。
7、配制泥浆前,需准备好一台型号W3.0/5的空压机,取代传统使用大功率泥浆泵来循环
泥浆的方式,这样能很好地保存泥浆的有效成分并发挥出泥浆的性能。
在配浆工作开始时,打开空压机进行运转,将所需泥浆材料全部冲散进泥浆池内后,空压机需至少要保持2个小时左右的工作方可将泥浆材料在池内充分的溶解开来,从而达到开工使用要求。
8、在钻进过程中,要求孔内泥浆的液面不得低于护简内侧高度的1/2位置,这样才能保
持好孔内的静柱压力,防止浆面下沉过大而导致孔内压力失衡出现蹋孔现象。
钻头在出入孔口时,提、放的速度要放缓,尽量减轻对孔内泥浆的扰动,保护孔壁的稳定,避免孔口坍塌,护筒下沉现象的出现。
当钻头打满提钻时,要适当反钻几下再缓慢提钻,这样可避免孔底因抽吸力过大而造成孔底部分出现坍蹋。
9、当孔钻到设计孔深后,钻机先暂不挪位,停留在原地,等待一会(视孔深而定,一般情况
下三十分钟为宜),用测绳测量孔深度,计算出沉渣厚度,再重新下钻捞取沉渣。
当钻头接近孔底时,需轻放,以免扰动沉渣,使沉渣浮起,捞起沉渣将钻头提起到孔口时,不要停留控浆,应迅速将沉渣甩出。
沉渣捞清后,孔内将不再有沉渣出现,便随即可下放钢筋笼,在放钢筋笼时应保持垂直,避免碰撞孔壁,以免造成新的沉渣产生。
10、钢筋笼下好后,开始下导管,事先请勿必检查好导管的密封条是否完好,接导管时,
要将导管的法兰拧紧,因为此泥浆属于无固相泥浆,较传统泥浆更易渗漏到导管内,因此只要拧紧导管,就能避免因导管漏水而造成混凝土离析,堵塞导管,影响灌注。
在灌注过程中,切忌不能逆时针方向转动导管,防止导管松动脱落,造成埋管现象的发生。
11、要求钻机工作人员注意保持好泥浆液面的高度,要及时给予孔内补浆。
钻机工作人
员需在开钻前测量并加固好钻头的直径尺寸,必须保证钻头尺寸符合施工要求,不能在施工过程中加扩钻头尺寸来扩孔,这样会造成蹋孔事故,所以不得扩孔。
