某十五层民用住宅楼的建筑给排水设计

摘要本设计是某十五层民用住宅楼的建筑给排水设计，主要包括给水系统、排水系统消防系统、热水系统和屋面雨水系统五个部分。给水系统采用分区供水，一到六层为低区，由市政管网直接供水。七层到十五层为高区，采用上行下给的供水方式，由地下车库的供水泵供水到屋顶的高位水箱，再由高位水箱向高区管网供水；排水系统采用的是污、废合流制，底层单独排水，排水立管仅设伸顶通气管，污水再经化粪池处理后排向市政污水管网；消防系统设计成消火栓灭火系统，火灾初期10min的水由消防水箱供给，正常供水由消防水泵从贮水池内抽取。热水采用的是封闭式机械半循环系统，分区情况和冷水系统一致，冷水通过电加热器集中加热后，再由提升泵供向配水管网；雨水采用的是内排水系统，雨水直接排向市政污水管网。给水管和排水管分别采用PP—R管和UPVC管，消防系统和热水系统都采用镀锌钢管。设计过程进行了各系统方案的确定、平面布置和计算,以及各种设备的选型,并做工程概算和Excel宏编制程序。最后用CAD绘制了各个系统的平面施工图和系统轴侧图。关键词：高层建筑；建筑给排水；给水管材AbstractThisdesignisa15layersbuildingsofthepublicresidencebuildingto,completingthedesignofthewatersupplysystemanddrainingthesystem,firefightsystem,thehotwatersystemandthesystemoftheroofrainwater.Thewatersupplysystemadoptioncentareasupplywater.1-6lowareasofthelayersistakencareofthedirectwatersupplybythemunicipalpipenet.Theseventhlayertothe15thlayerishigharea,adoptionnorthbounddescendtoofwatersupplymethod,pumptosupplywatertoawatertankoftherooffromthewatersupplyoftheundergroundgarage,thenbetakencareofthenetwatersupplytowardhighareabyawatertank;Drainthesystemadoptionisadirtywater,thewastewaterconfluencesystem,thefirstfloordrainsalone,drainingtosignthetubetoestablishtostretchthecresttoventilatethetubeonly,thedirtywaterwashandlebyseptictankagainrearrowtomunicipalsoilpipenet;Thefirefightsystemdesignbecomestoeliminatethefiretobolttoextinguishfirethesystem,afirewateroftheearly10minsissupplybythefirefightwatertank,normalthewatersupplybepumpedbythefirefightPumpfromtheSavingpond;Thehotwatersystemdividestheareacircumstanceinaccordancewiththecoldsystemofwater,thecoldwaterpassestogiveorgetanelectricshockaftertheheatingapparatusconcentrationheat,againfrompromotethepumptoprovidetogotogetherwiththepipelinenet,Thehotwateradoptistheclosingtypemachinehalfcirculatorysystem;Therainwateradoptionisinsidedrainthesystem,rainwaterdirectrowtomunicipalsoilpipenet.ThewaterpipeanddrainpipesrespectivelyadoptthePP-RtubeandtheUPVCtubes,thefirefightsystemandthehotwatersystemsesalladopttoplatethezincsteelpipe.Inthedesignationprocess,Icarriedonsettlingeachsystemproject,theflatsurfacearrangesandcomputing,andchoseingthetypeofvariousequipments,anddothegreatengineeringbudgetestimationandestablishmentprocedureoftheExcel.finally,DrewtheflatsurfaceconstructiondiagramandthesystemstalksidediagramsofeachsystemwiththeCAD.Keywords:highbuilding;watersupplyanddrainageofbuildings;Waterpipematerial目录1.文献综述.............................................................................................................................61.1建筑给排水工程设计的发展历史..............................................................................61.2建筑给排水工程在水工业中的地位..........................................................................61.3国内外高层建筑给水排水工程设计研究的状况和主要内容................................71.3.1高层建筑给水排水工程设计方法..............................................................71.3.1.1高层建筑生活给水......................................................................71.3.1.2高层建筑消防给水......................................................................71.3.1.3高层建筑排水..............................................................................81.3.2高层建筑给水排水设计的主要内容........................................................81.3.2.1给水工程设计的主要内容........................................................81.3.2.2室内消防设计的主要内容........................................................81.3.2.3排水工程设计的主要内容........................................................91.3.2.4热水工程设计的主要内容........................................................91.4总结92设计任务书.....................................................................................................................92.1工程概况......................................................................................................................102.2设计依据......................................................................................................................102.3设计基础资料.............................................................................................................102.4设计参数......................................................................................................................102.5设计内容......................................................................................................................102.6设计成果......................................................................................................................113设计计算书.....................................................................................................................123.1室内给水工程（冷水）.............................................................................................123.1.1系统的选择.................................................................................................123.1.2系统的组成.................................................................................................133.1.3设计参数及水量.........................................................................................133.1.4加压设备及构筑物.....................................................................................133.2室内排水工程....
