给排水管道计算说明书

前言

给水排水管道工程是给水排水工程的重要组成部分，可分为给水管道工程和排水管道工程两大类。

给水管道工程是论述水的提升，输送，贮存，调节和分配的科学。其最基本的任务是保证水源的原料水送至水处理构筑物及符合用户用水水质标准的水输送和分配到用户。这一任务是通过水泵站，输水管，配水管网及调节构筑物等设施的共同工作来实现的，它们组成了给水管道工程。设计和管理的基本要求是以最少的建造费用和管理费用，保证用户所需的水量和水压，保证水质安全，降低漏损，并达到规定的可靠性。

给水排水管网工程是给水排水工程中很重要的组成部分,所需投资也很大,一般约占给水排水工程总投资的70%~80%。同时管网工程系统直接服务于民众,与人们生活和生产活动息息相关,其中任一部分发生故障,都可能对人们生活、生产及保安消防等产生极大影响。因此,合理地进行给水排水管道工程规划、设计、施工和运行管理,保证其系统安全经济地正常运行,满足生活和生产的需要,无疑

是非常重要的。

室外给水排水工程是城镇建设的一个重要组成部分，其主要任务就是为城镇提供足够数量并符合一定水质标准的水；同时，把人们在生活、生产过程中使用后的污水汇集并输送到适当地点进行净化处理，达到一定水质标准后，或重复使用，或灌溉农田，或排入水体。室内给水排水工程的任务是将室外给水系统输配的净水组织供应到室内各个用水点，将用后的污水排除汇集到室外排水系统中去。

做为工程类专业学生，实践学习和设计是我们自身获取知识和经验的最好环节。学生通过设计，综合运用和深化所学的基本理论、基本技能，培养我们独立分析和解决问题的能力，通过设计能使我们具有掌握查阅规范、标准设计图集，熟练使用cad操作技术，并且培养了我们的初步设计思维，为我们以后的设计道路打下一些基础。

Foreword

Water supply and sewer project is an important part of the water supply and drainage works can be divided into water and sewer pipeline project works in two categories.

Water supply pipeline project is to enhance the discussion of water , transportation , storage, regulation and distribution of science. Its primary task is to ensure that the raw water to the water treatment structures and compliance with water quality standards for water users transmission and distribution to users. This task is accomplished by pumping stations , water mains , water distribution network and adjust structures and other facilities to work together to achieve, they formed a water pipeline project . Design and management of the basic requirements are minimal construction costs and management fees, water and pressure to ensure that users need to ensure quality and safety , reduce leakage , and meet reliability requirements .

Water supply and drainage network engineering is a very important water and wastewater engineering part of the required investment is large, generally about 70 % to 80% water supply and drainage of the total investment . Meanwhile pipe network engineering systems directly serve the public , and is closely related to people's life and production activities , including failure of any part , may have a significant impact on people's lives , fire and other production and security . Therefore, a reasonable

water supply and drainage pipeline project to carry out the planning , design, construction and operation management, to ensure their systems running safely and economically meet the needs of life and production , is undoubtedly very important. Outdoor Water Supply and Drainage is an important part of urban construction , and its main task is to provide a sufficient number of towns and meet certain water quality standards ; while sewage pooled and transferred to the appropriate place in the life of the people use , after the production process purification treatment , after reaching a certain quality standard , or reuse , or irrigated cropland , or discharged into water bodies . Indoor water and wastewater engineering task is to organize outdoor water distribution system supplies water to the interior of each water point , with the exclusion of the sewage collection of outdoor drainage systems go.

As engineering students, hands-on learning and design our own knowledge and experience to get the best link. Students through the design, the integrated use of the basic theory and deepen learning , basic skills, to develop our independent analysis and problem-solving ability , through the design enables us to have the ability to consult specification , standard design atlas , skilled operation using cad technology, and culture our preliminary design thinking , laying some of the foundation for our future design path.
