给水排水管道工程 课程设计.doc

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(建设)投资也很大,一般约占给水排水工程总投资的50%~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。Foreword Water drains, water supply and drainage project is an important component of the project can be divided into drains and water supply pipeline project works two categories. Water pipeline project is on the upgrading of water, transmission, storage, distribution and regulation of science. Its most basic task is to ensure that the raw water source sent to the water treatment structures and water users with the water quality standard transmission and distribution to users. This task through the pump stations, pipelines, distribution mains network structure and regulation and other facilities to work together to achieve, and they formed a water pipeline project. Design and management is a basic requirement for at least the construction costs and management fees to ensure that the necessary water users and pressure to ensure water quality and safety, reduce leakage and achieve the required reliability. Water drainage network project is a water supply and drainage project in the very important component of the needs (building) there is also a great investment, the general water supply and drainage works about a total investment of 50% to 80%. At the same time network engineering systems direct services to the people, and peoples lives and production activities are closely related, as part of a fault may be on peoples lives, such as production and security have a g
