摘要本设计是二十一层宾馆的建筑给排水设计,主要包括给水系统、排水系统、消防系统、热水系统。给水系统采用分区供水,一到二层为为一区,由市政管网直接供水;三层到十二层为二区,十三层到二十一层为三区。由水泵从地下贮水池加压供水,并设变频调速装置。排水系统采用污、废水分流制,坐便器出水直接排入市政污水管网;底层单独排水,排水立管设专用通气管。消防系统主要采用室内消火栓系统,火灾初期10min消防用水量由屋顶消防水箱供给,消防水箱的水源由生活水泵从生活水池抽取;10min后的消防启动消防水泵,从消防水池抽水供消火栓使用。热水系统采用闭式机械循环系统,热水的分区系统同冷水系统;采用集中热水供应,热源来自市政热媒管网(0.20MPa),冷水经过容积式加热器加热后供向配水管网。关键词建筑给排水高层建筑AbstractThedesignofcompositehotelbuildingsistheconstructionof21watersupplyanddrainagedesign,includingwatersupplysystem,drainagesystems,fireprotectionsystem,hotwatersystems.Watersupplysystemusingregionalwatersupply,1to2forfirst,thenetdirectfromthemunicipalwatersupply;3to12forsecond,frompumpsfromundergroundstoragepondpressurizedwatersupply,andbasedFrequencyControlDevices,13to21forthirdareas,fromwaterpumpsfromundergroundstoragepondpressurizedwatersupply,andbasedFrequencyControlDevice.Asewagedrainagesystem,wastewaterdiversionsystem,Toiletwaterdirectlyintothemunicipalsewernetwork;bottomseparatedrainage,drainageLegislativetrachealtube-baseddedicated.Firehydrantsystemismainlyusedindoors,10minfireearlyfirefromtheroofwatersupplytankfire,watertanksofwaterfromfirepumpslifetakenfromthepondlife;10minafterthefirestartedfirepumps,pumpingwaterfromafirehydrantavailableforuse.Closed-mechanicalsystemsusinghotwatercirculationsystem,thewaterdistrictsystemandthecoldwatersystem,usedonhotwatersupply,heatfromtheHTMNetworkServices(0.20MPa),Coldwateraftervolumetricheatingforthewaterdistributionnetwork.3目录前言........................................................................................................................11设计说明书........................................................................................................21.1室内给水工程............................................................................................21.1.1给水方式的选择........................................................................21.1.2系统的组成................................................................................31.1.3设计参数及水量........................................................................31.1.4地下室贮水池容积....................................................................41.2建筑消防工程........................................................................................41.2.1消防栓系统选择........................................................................41.2.2室外消火栓的设计....................................................................61.2.3自动喷水灭火系统的设计........................................................61.2.4灭火器的配置............................................................................71.3建筑排水工程........................................................................................81.3.1系统选择....................................................................................81.3.2系统组成....................................................................................81.4建筑热水工程........................................................................................91.4.1系统选择....................................................................................91.4.2系统布置....................................................................................91.4.3系统的组成................................................................................91.4.4主要设备..................................................................................102管道及设备安装................................................................................................102.1给水管道设备安装要求.........................................................................102.2消防管道设备安装要求.........................................................................112.2.1消火栓系统................................................................................112.2.2自动喷水灭火系统....................................................................112.3排水管道设备安装要求.........................................................................122.4热水管道设备安装要求.........................................................................123设计计算书........................................................................................................1343.1室内给水系统的计算.............................................................................133.1.1给水用水量计算........................................................................133.1.2给水管网水力计算....................................................................153.2消火栓系统的计算.................................................................................193.2.1室内消火栓给水系统的水力计算..............................................193.3室外消火栓系统计算.............................................................................253.3.1室外消火栓计算........................................................................253.4自动喷水灭火系统的计算.....................................................................253.4.1设计基本数据............................................................................253.5排水系统的计算.....................................................................................293.5.1计算资料.........................................................................
