《给水排水管道系统》课程设计 说明书 题 目：学 院：市政与环境工程学院 专 业：给排水工程 姓 名： 学 号：02441 指导老师： 完成时间：2013年月日 随着现代建设的发展，给水排水逐渐发展成一门国家重要学科。给排水工程可以分为给水管道工程和排水管道工程两大类。 给水排水管道系统的学习应用已经表现在社会生活中越来越重要的地位，城市的现代化建设都离不开给水排水。所以学好给水排水对我们将来建设现代化城市有极其重要的作用，我们很重视这次给水排水课程设计。 我们这次课程设计主要任务是设计某城市某地区的给水排水管道设计：它主要包括城市给水管网扩初设计和城市排水管网扩初设计。在设计过程中要首先仔细阅读设计任务书中的原始资料，对设计的该城市有全面的了解。 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  Foreword With the development of modern construction, water supply and drainage gradually developed into a national key discipline. Water supply and drainage engineering can be divided into the pipeline of water supply engineering and drainage pipeline project in two categories. Water supply and drainage pipe system learning applications have been demonstrated in social life is becoming more and more important position, city modernization is inseparable from the water supply and drainage. So well of water supply and drainage for our future construction modernization city are extremely important role, we attach great importance to the water supply and drainage design. Our design of this course the main task is the design of a city in a certain area of the feed water and drainage pipeline design: it mainly consists of city water supply network preliminary design and city drainage pipe network expansion design. In the design process to first read the design task Book Sourcebook, to design the city has a comprehensive understanding of. Water supply and drainage pipe networks of water supply and sewerage engineering project is a very important part of the required ( construction ), investment is large, generally about water supply and drainage projects with a total investment of 50% - 80%. At the same time, network engineering system directly to serve the people, and the p
