《给水排水管道系统》课程设计计算说明书题目：长沙市给水排水管道工程设计学院：市政与环境工程学院专业：给排水科学与工程姓名：庄晨学号：024411110指导老师：谭水成、张奎、宋丰明、刘萍完成时间：2013年12月26日前言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。ForewordWiththedevelopmentofmodernconstruction,watersupplyanddrainagegraduallydevelopedintoanationalkeydiscipline.Watersupplyanddrainageengineeringcanbedividedintothepipelineofwatersupplyengineeringanddrainagepipelineprojectintwocategories.Watersupplyanddrainagepipesystemlearningapplicationshavebeendemonstratedinsociallifeisbecomingmoreandmoreimportantposition,citymodernizationisinseparablefromthewatersupplyanddrainage.Sowellofwatersupplyanddrainageforourfutureconstructionmodernizationcityareextremelyimportantrole,weattachgreatimportancetothewatersupplyanddrainagedesign.Ourdesignofthiscoursethemaintaskisthedesignofacityinacertainareaofthefeedwateranddrainagepipelinedesign:itmainlyconsistsofcitywatersupplynetworkpreliminarydesignandcitydrainagepipenetworkexpansiondesign.InthedesignprocesstofirstreadthedesigntaskBookSourcebook,todesignthecityhasacomprehensiveunderstandingof.Watersupplyanddrainagepipenetworksofwatersupplyandsewerageengineeringprojectisaveryimportantpartoftherequired(construction),investmentislarge,generallyaboutwatersupplyanddrainageprojectswithatotalinvestmentof50%-80%.Atthesametime,networkengineeringsystemdirectlytoservethepeople,andthepeople'slivingandproductionactivitiesarecloselyrelated,anyportionofthefailure,cantopeoplelife,productionandsecurityfireandotherproducegreatinfluence.目录第1章课程设计任务书.................................................1第2章给水管网设计与计算............................................32.1给水管网布置及水厂选址.......................................32.2给水管网设计计算.............................................42.2.1一区水量计算............................................42.1.2二区水量计算.............................................72.2给水管网水力计算..............................................92.2.1一区给水管网水力计算.....................................92.2.2二区给水管网水力计算....................................122.3管网平差.....................................................132.3.1环状管网流量分配计算与管径确定.........................132.3.2环状管网平差............................................162.3.3水压计算................................................162.4二级泵站....................................................18第3章污水管网设计与计算...........................................203.1污水设计流量计算............................................203.2污水管道水力计算........................
