设计总说明本设计为南京某医院给水排水及消防工程设计，设计的主要内容包括：建筑给水系统设计，建筑排水系统设计，建筑雨水排水系统设计，消火栓给水系统设计，自动喷淋系统设计。本建筑地下一层，地上九层。地下层为汽车库、自行车库和水泵房、仓库等，地上一层至四层为门诊部；四层与五层中间是设备层，层高为；五层至八层是医院住院部，层高为，九层医院管理办公用房。市政管网压力为0.35MPa,由于本建筑属于高层建筑，室外管网只能满足下面几层的供水，所以给水系统采用分区供水方式。地下一层至地上四层采用室外官网直接供水，五至九层采用变频调速恒压给水方式。因为室外管网不允许直接抽水，则在地下一层设置贮水池。本设计采用生活污水和生活废水合流制排水系统，卫生间采用污、废合流制排至室外污水检查井，诊室废水排至室外废水检查井。医院卫生间污废水先经化粪池处理后，再与医院诊室废水汇合排至室外医院污水处理构筑物，经处理达标合格后排至室外污水管网。排水立管设伸顶通气管或汇合通气管。一层排水直接排至室外，地下室废水经潜污泵提升至室外检查井。雨水采用的是内排水系统，雨水直接排至室外雨水管网。消火栓系统包括室内和室外消火栓给水系统，该建筑物高度低于70米，，故消防不分区，低层设减压孔板减压。消火栓保护半径为28.5米。本建筑属于中危险级，其中地上部分为中危险级Ⅰ级，地下一层车库属于中危险级Ⅱ级。在建筑的诊室、大厅、病房等公共活动场所、走廊、地下车库等处均应设置闭式自动喷水灭火系统。设3个湿式报警阀，报警阀后管网为枝状网，每层设水流指示器、信号阀，自喷系统竖向分三个区，与消火栓系统合用消防水箱。重要设备用房等不宜用水消防的部位设置热气溶胶预制灭火系统。关键词：建筑给水系统，排水系统，消火栓系统，自动喷淋系统AbstractThedesignforahospitalinNanjingWaterandfireengineeringdesign,designofthemaincontentsinclude:buildingwatersupplysystemdesign,constructionofdrainagesystemdesign,architecturaldesignofdrainagesystems,firehydrantwatersupplysystemdesign,automaticsprinklersystemdesign.Thebuildinghasabasement,therearenineontheground.Thebasementofthegarage,bicyclestorageandpumphouse,storage,etc.,onthegroundfloortofourfortheclinic;fourandfiveareintermediatedevicelayer,theheightis2.1m;fivetoeighthospitalinpatient,theheightof3.9m,thenine-storyofficebuildingisthehospitalmanagement.Municipalpipenetworkpressureis0.35MPa,sincethepresentbuildingbelongstothehigh-risebuildings,outdoorpipenetworkwatersupplycanonlymeetthefollowinglayers,sothewatersystemispartitionedwatersupply.Basementtothegroundfouroutdoorofficialwebsiteusedirectwatersupply,fivetoninefrequencycontrolconstantpressurewatersupplymode.Becauseoutdoorpipenetworkdoesnotallowdirectpumpinginthebasementsetupstoragetanks.Thisdesignusessewageanddomesticwastewatercombinedsewersystems,toiletusesewage,wasteCombinedsewagedischargedtotheoutdoormanholes,officewastewaterdischargedintotheoutdoorwastewatermanholes.Hospitaltoiletafterfirstseptictanksewageandwastetreatment,andthenthehospitalclinicconfluencewastewaterdischargetotheoutsidehospitalsewagetreatmentstructures,StandardsCompliancetreatedsewagepipenetworkbacktotheoutdoors.Drainriserextendingtopsnorkelsetsnorkelorconvergence.Floordraindirectlytotheoutsiderow,wastewatersubmersiblesewagepumpbasementupgradetooutdoormanholes.Rainwaterisusedinthedrainagesystem,rainwaterdirectlytotheoutsiderowstormsewer.Hydrantsystemincludesindoorandoutdoorfirehydrantwatersupplysystem,thebuildingheightoflessthan70meters,itisnotthefiredistrict,thelowersetpressureplatedecompression.Hydrantprotectionradiusof28.5meters.Thebuildingbelongstothedangerouslevel,whichisthedangerouslevelabovegroundlevel1,basementgaragebelowthedangerouslevel2.grade.Inofficebuildings,halls,andotherpublicvenueswards,corridors,undergroundgarage,etc.shallbeprovidedwithaclosedsprinklersystem.Setupthreewetalarmvalve,pipenetworkafterthealarmvalvedendriticnetwork,eachsetflowindicator,signalvalvefromthespraysystemisdividedintothreeverticalzones,combinationfirewatertankandhydrantsystems.Importantequipment,buildings,etc.shouldnotsetthehotwaterforthesiteofaerosolfireextinguishingsystemsprefabricated.Keywords:buildingwatersupplysystems,drainagesystems,firehydrantsystem,automaticsprinklersystem目录1绪论.........................................................................................................................................11.1概述..............................................................................................................................11.2设计原始资料及工程概况..........................................................................................11.3设计目的......................................................................................................................11.4设计任务与要求.........................................................................................................12设计说明................................................................................................................................32.1室内给水系统...............................................................................................................32.1.1给水系统选择.....................................................................................................32.1.2给水系统组成.....................................................................................................42.1.3加压设备及构筑物.............................................................................................42.1.4管道的布置级敷设.............................................................................................42.2室内排水系统...............................................................................................................52.2.1排水系统选择.....................................................................................................52.2.2排水系统组成.....................................................................................................72.2.3管材、管道的布置和敷设.................................................................................72.3雨水排水系统....................................
