第页常州某住宅小区市政给排水管网设计摘要：本次毕业设计对象为常州市某住宅小区，设计范围为道路红线范围内的室外给水排水管道。该小区位于郊区，采用城市自来水为供水水源，引入两路自来水管在小区内形成环状管网，供应小区生活及消防用水。小区建筑按二类高层设计，小区排水体制采用雨污分流制，小区雨、污水最终接入小区外的市政雨、污水干管。根据国家现行的设计施工规范和总图专业提供的总平面图、设计原始资料来布置雨、污管网，并选择合理的定线方案，阐述采用的管材、埋设深度、接口形式、雨水口、检查井和消火栓的布置原则。对给水、污水、雨水管网进行相关的水力计算，确定管径等水力参数。从满足人们优良生活环境和确保小区给排水管网的安全环保可持续发展的角度出发，合理布局，创造一个环境优美、设施齐全的新型住宅小区。关键词：水力计算；管网布置；给水管网；排水管网；雨水管网MunicipalwatersupplyanddrainagenetworkdesignforaresidentialareainChangzhouAbstract:ThegraduationdesignobjectisforaresidentialareainChangzhou.Thedesignareaisoutdoorwaterdrainagepipelineswithinthescopeoftheredlineoftheload.Thehousingdistrictislocatedinthesuburbs,tapwatersupplysourcebycityforintroducingtworoadwaterpipescompoundinginacircularpipenetworkforvillagelifeandfirewater.ThedesignoftheresidentialareaaccordingtoClass-1residentialincludesrainandsewagedrainagesystem.Communityrainwateroutsidethemunicipaldistrictfinalgoestoraintrunksewers.Thedrainagesysteminthedistrictadaptsshuntingsystemofrainanddirtywater.Accordingtotheprincipleofthecurrentnationaldesign,constructionstandardsandtheprincipleofthegeneralplanwhichprovidesprofessionaldesignandgeneralinformationonoriginalpipelinelayoutIchosethereasonableplan.AndthenIexplaintheusingpipes,theembeddingdepth,theformofinterfaceandgully.Finally,IcheckthearrangementofPenstockanddesignofwatersupply,sewageandrainsystem.AndIdosomehydrauliccalculationtothesupplyingwater,dirtywaterandrainingwater.Tomeettheneedofpeoplelivingintheenvironment,ensurethesafetyofcommunitywatersupplyanddrainagenetworkandforthesustainabledevelopmentofenvironmentalprotection,rationaldistribution,weshouldcreateabeautifulenvironment,anewresidentialdistrictfacility.Keywords：hydrauliccalculation;networklayout;watersupplypipe;sewagepipe;rainingpipeTOC\o"1-3"\h\z\uHYPERLINK\l"_Toc294790985"摘要ⅠHYPERLINK\l"_Toc294790987"目次ⅢHYPERLINK\l"_Toc294790988"术语表ⅤHYPERLINK\l"_Toc294790989"1引言PAGEREF_Toc294790989\h1HYPERLINK\l"_T
