给水排水管道系统课程设计16

I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。做为工程类专业学生，实践学习和设计是我们自身获取知识和经验的最好环节。学生通过设计，综合运用和深化所学的基本理论、基本技能，培养学生独立分析和解决问题的能力，通过设计能使学生具有：①掌握查阅规范、标准设计图集，产品目录的方法，提高计算、绘图和编写设计说明的水平，作好一个工程师的基本训练。②熟练城镇给水排水工程系统的详细计算和培养一定的理论分析和设计的能力。提高方案的比较、技术经济、环境、社会等诸方面的综合分析和论证能力。③培养计算机操作和应用能力。熟练专业软件应用。IIForewordWaterdrains,watersupplyanddrainageprojectisanimportantcomponentoftheprojectcanbedividedintodrainsandwatersupplypipelineprojectworkstwocategories.Waterpipelineprojectisontheupgradingofwater,transmission,storage,distributionandregulationofscience.Itsmostbasictaskistoensurethattherawwatersourcesenttothewatertreatmentstructuresandwateruserswiththewaterqualitystandardtransmissionanddistributiontousers.Thistaskthroughthepumpstations,pipelines,distributionmainsnetworkstructureandregulationandotherfacilitiestoworktogethertoachieve,andtheyformedawaterpipelineproject.Designandmanagementisabasicrequirementforatleasttheconstructioncostsandmanagementfeestoensurethatthenecessarywaterusersandpressuretoensurewaterqualityandsafety,reduceleakageandachievetherequiredreliability.Waterdrainagenetworkprojectisawatersupplyanddrainageprojectintheveryimportantcomponentoftheneeds(building)thereisalsoagreatinvestment,thegeneralwatersupplyanddrainageworksaboutatotalinvestmentof50%to80%.Atthesametimenetworkengineeringsystemsdirectservicestothepeople,andpeople'slivesandproductionactivitiesarecloselyrelated,aspartofafaultmaybeonpeople'slives,suchasproductionandsecurityhaveagreatimpactonfire.IIITherefore,thereasonablewaterdrainageworksfortheplanning,design,constructionandoperationofmanagement,guaranteethesecurityofitssystemtonormaloperationoftheeconomytomeettheneedsoflifeandproduction,andthisiscertainlyveryimportant.Outdoorurbanwatersupplyanddrainageprojectistheconstructionofanimportantcomponentofitsmaintasksistoprovideadequatenumberoftownsandmeetcertainwaterqualitystandards;Atthesametime,peopleinthelifeoftheproductionprocesstousetheeffluentwaterpoolingandtransportedtoasuitablesiteforpurificationofuptoacertainqualitystandard,orrepeateduse,orirrigationordischargedintothewaterbody.Indoorwatersupplyanddrainageprojectisthetaskofdistributionofoutdoorwatersupplysystemtosupplywaterpurificationorganizationsinallindoorwater,thesewagewillbeusedtowatertoremoveoutdoorpooldrainagesystems.Doesfortheprojectclassspecializedstudent,thepracticestudyandthedesignisourownknowledgeacquisitionandtheexperiencebestlink.Moreoverinthegraduationprojectundergraduatecourseplanofinstructiontheessentiallink,aftertheundergraduatecoursestipulatesthepracticaleducationwhichcompletesthecompletecurriculumtohavetocarryon,thestudentthroughthegraduationproject,thesynthesisutilizestheelementarytheory,thebasicskillwhichanddeepensstudies,trainsIVthestudentindependentlytoanalyzeandtosolvethequestionability,canenablethestudentthroughthegraduationprojecttohave:(1)Graspstheconsultstandard,thestandarddesignatlas,theproductcatalogmethod,enhancesthecomputation,thecartographyandthecompilationdesignexplanationlevel,finishesanengineer'sbasictraining.(2)Skilledcitiesgivethewaterseweragesystemthedetailedcomputationandtheraisecertaintheoreticalanalysisandthedesignability.Enhancestheplanthecomparison,thetechnicaleconomy,theenvironment,thesocietyandsoonthevariousaspectsgeneralizedanalysisandprovestheability.(3)Raisecomputeroperationandapplicationability.Skilledspecializedsoftwareapplication.V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...........................................42.3清水池调节容积.............................................72.3.1一区清水池调节容积.....................................72.3.2二区清水池调节容积.....................................72.4管网水力计算...............................................82.4.1最大时集中流量为：.....................................82.4.4节点流量:.............................................112.5管网平差..................................................122.5.1环状管网流量分配计算与管径确定........................122.5.2环状网平差(最高用水时)：..............................142.5.3水压计算..............................................142.5.4二级泵站..............................................162.6消防校核...................................................17第3章污水管网设计与计算..........................................183.1污水设计流量计算...........................................183.2污水管道水力计算..........................................183.2.1设计要求.................................................
