摘要本设计是十六层小高层宾馆的建筑给排水设计，主要包括给水系统、排水系统、消火栓系统、自动喷淋系统。给水系统采用分区供水，一到四层为低区，由市政管网直接供水；五层到十六层为高区，由水泵从地下贮水池加压供水，由变频调速泵加压供水。给水系统管材使用PP-R塑料管材。排水系统采用污、废水合流制；一、二层裙房部分单独排水，排水立管不设专用通气管，管材使用铸铁管。消火栓系统采用临时高压供水系统，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地下贮水池抽取；10min后启动消防水泵，从地下贮水池抽水供消火栓使用。自动喷淋系统设置3组湿式报警阀组，-1至4层共用一组，5至10层共用一组，11-16层共用一组。系统使用预作用报警系统，火灾前3min系统供水由屋顶水箱供给，3分钟后由水泵从地下贮水池抽取供给。关键词：给水；排水；消火栓；自喷；高层建筑IAbstractThedesignisa16-storeyhigh-risehotelbuildingwatersupplyanddrainagedesign,includingwatersupplysystem,drainagesystem,firehydrantsystem,automaticsprinklersystem.Watersupplysystemispartitioned,onetofourforthelowzone,directlyfromthemunicipalwatersupplypipenetwork;fiveto16arehighareas,undergroundstoragetankbythepumppressurefromthewater,pressurizedwaterfromthepumpfrequencycontrol.WatersupplysystemusingthePP-Rpipeplasticpipe.Drainagesystemwithsewage,wasteCombined;firstandthesecondskirtpartofaseparatedrainage,drainageriserwithnospecialventilationtube,pipewithcastironpipe.Theuseoftemporaryhigh-pressurefirehydrantsystem,watersupplysystems,firewaterfromtheroofofthefireearly10minsupplyfirewatertank,firepumptankwaterbythelifetakenfromtheundergroundstoragetank;10minafterthestartthefirepump,pumpingfromundergroundstoragetankforfirehydrantuse.Automaticsprinklersystemsetupthreegroupsofpre-actionalarmvalve,-1toshareasetofLayer2,Layer3to9,10-16shareacommonsetoflayers.Systemusespre-actionalarmsystem,firesystemwatersupplyfromtheroofbeforethe3minsupplytank,3minutesfromtheundergroundstoragetankbythepumptakingsupply.Keywords:watersupply；drainage；firehydrant；flowing；high-risebuildingIIIII目录前言...........................................................................................................................11工程概况及设计任务...........................................................................................21.1工程概况............................................................................................................21.2工程设计任务....................................................................................................22建筑内给水系统...................................................................................................42.1给水管道及设备安装........................................................................................42.1.1管道布置和敷设的一般原则.....................................................................42.1.2管道敷设要求.............................................................................................42.2系统选择............................................................................................................52.3给水系统计算....................................................................................................52.3.1最高日用水量计算.....................................................................................62.3.2最高日最高时用水量计算.........................................................................72.3.3设计秒流量计算.........................
