给水排水管网课程设计(打印)

河南城建学院《给水排水管网系统》课程设计班级026413163专业给排水科学与工程设计时间2015.12.21～2016.1.1设计地点九号楼A502课程名称给水排水管网系统指导教师谭水成市政与环境工程学院2015年12月前言课程设计是课程学习期间的一项重要的实践性教学环节，是获得工程知识必不可少的锻炼和实现培养目标的重要手段。本次课程设计为杭州市给水排水管道工程设计，设计时间为两周。整个设计包括三大部分：给水管道设计、污水管道设计和雨水管道设计。在大致了解杭州市地形位置和分布后，我决定采用整体供水满足城市用水需求的供水方案。给水管道的设计内容主要包括管线布置及水厂选址、设计流量的计算、清水池容积的确定、管网的水力计算、管网平差和校核等。考虑到城市的初步规划以及资金投资问题，排水体制采用完全分流制，即污水和雨水分别设置独立的管道系统。生活污水和工业废水通过污水排水系统送至污水处理厂，经处理后再排入水体；雨水是通过雨水排水系统直接排入水体。排水管道的设计内容主要包括排水体制的确定、设计流量计算和管网水力计算。课程设计让我们结合所学知识，运用CAD、鸿业软件进行绘图和平差校核计算，绘制出自己设计的给水排水管道总平面布置图和污水干管纵剖面图。通过课程设计，我们可以将以前学的基础理论、基本技能及专业知识有机地统一起来，形成一个较为全面的专业知识水平能力框架，为今后更深层次的专业学习打下坚实的基础。PrefaceCurriculumdesignisnotonlyansignificantpracticalteachinglinkduringthestudyofcourse,butalsoanrequisiteexercisetoobtainengineeringknowledgeandanimportantmeantorealizethetrainingobjectives.ThecurriculumdesignistheHangzhouwatersupplyanddrainagepipelineengineeringdesign,anddesigntimeistwoweeks.Thewholedesignisdividedintothreeparts:thedesignofthewatersupplypipeline,thedesignofthesewagepipeandthedesignoftherainwaterpipeline.InthegeneralunderstandingofHangzhoutopographiclocationanddistribution,Idecidedtousetheoverallwatersupplyschemetomeetthedemandforurban.WatersupplypipelinedesigncontentmainlyincludesPipelinelayoutandwaterplantsiteselection,calculationofthedesignedflowrateofwatersupplypip,determinationofthevolumeofclearwatertank,Hydrauliccalculationofpipenetwork,adjustmentandcheckofpipenetworkandsoon.Consideringtheproblemofcitiesintheinitialplanningandcapitalinvestment,thedrainagesystemadoptsfullstreaming,namelysewageandrainwaterarerespectivelyarrangedindependentlyofthepipelinesystem.Domesticsewageandindustrialwastewaterthroughthesewagedrainagesystemtosendtothesewagetreatmentplant,treatedandthendischargedintothewater;rainwateristhroughrainwaterdrainagesystemisdischargeddirectlyintowaterbodies.Thedesigncontentmainlyincludesthecalculationofdrainagepipedrainagesystemdeterminationofdesignflowcalculationandhydraulic.Curriculumdesignletuscombinedwiththeknowledge,usingCAD,Hongyesoftwaredrawingpeacedifferencecalculation,drawstemdesignedforwatersupplyanddrainagepipelineingenerallayoutdrawingandthesewagepipeprofile.Throughthecurriculumdesign,wecanunifypreviousthebasictheory,basicskillsandprofessionalknowledge,theformationofamorecomprehensiveprofessionalknowledgelevelframework,forthefutureinadeeperlevelofprofessionalandlayasolidfoundationforlearning.目录第一章课程设计任务书...............................................................................................................11.1设计题目：..............................................................................................................................11.2原始资料：..............................................................................................................................11.3课程设计内容：.....................................................................................................................11.3.1城市给水管网扩初设计.............................................................................................11.3.2城市排水管网扩初设计.............................................................................................21.4设计参考资料.........................................................................................................................21.5设计成果.................................................................................................................................21.6要求.........................................................................................................................................21.7其他.........................................................................................................................................2第二章给水管网设计与计算.......................................................................................................32.1供水方式的选择.....................................................................................................................32.2给水管网的布置.....................................................................................................................32.2.1水厂的选址原则.........................................................................................................32.2.2管网定线要求.............................................................................................................32.3基本数据的确定.....................................................................................................................42.4设计用水量计算.....................................................................................................................42.4.1最高日设计用水量计算.............................................................................................42.5清水池调节容积.....................................................................................................................52.6管网水力计算.........................................................................................................................62.6.1集中流量的计算：......................................................................................
