I摘要长信大厦是为了满足公差旅游、休闲、外出的需要，而为旅客提供住宿、参观、社交、娱乐等多种服务，位于湖南省沅江市繁华地段的一座多功能建筑。建筑面积为12943.9m2,本建筑最高层为八层，建筑高度为33.50m。该建筑地下一层为车库、配电室、水泵房、设备间等，室内地面标高为-3.50m；地上八层，一层为商铺，层高为6.0m；二层为茶艺大厅和包房，层高为5.0m；三层为厨房、包房和餐厅，层高为5.0m；四、五层为客房、会议室、办公室，层高为3.0m；六、七层为客房、会议室，层高为3.0m；八层为多功能大厅和仓库，层高为3.0m；具体布置如工程图纸所示。水源由市政给水管网提供，其常年压力为0.3Mpa。水源由市政给水管网供给，该设计给水系统采用分区供水方式，低区为地下一层至地上三层，高区为四层至八层，高低区均采用水泵水箱联合供水。消防系统采用消火栓灭火系统、自动喷淋灭火系统相结合的方式，消火栓灭火系统管网布置成环状，在建筑外侧设两个水泵接合器，当水量不足时可由室外消防车通过水泵接合器供水。自动喷淋灭火系统采用独立的湿式自动喷水灭火系统，该系统具有灭火及时，效率高的优点，但也存在缺陷，由于管网中充有有压水，当渗漏时会损坏建筑和影响建筑物的使用。该建筑的功能决定采用集中热水供应，由于集中热水供应系统可以集中设置加热和其他设备，便于集中维护管理；加热设备热效率高，热水成本较低；各热水使用场所不必设置加热装置，占用总建筑面积较少；使用较为方便舒适。本设计排水系统采用生活污水和生活废水合流排放，地下室污水采用单独排出，多根排水立管在建筑物顶部共用伸顶通气立管。雨水系统采用外排水系统，设单斗雨水立管，雨水斗采用87型，材料为塑料。关键词：给水系统；消火栓系统；自动喷淋灭火系统；热水系统；排水系统；雨水系统。IIAbstractJinTianBuildingislocatedinthedowntownareaofYuanjiangCity,HunanProvince.Itismulti-functional,whichcanprovidepassengerswithaccommodation,sight-seeing,socialservice,entertainmentandotherservicessoastomeetpassengers’requirementsintheirbusinesstravel,leisuretravelandetc.The33.50-meterhighbuildinghas8floorsanditcovers12943.9m2.Thefirstfloorundergroundisusedasgarage,switchgearroom,waterpumproom,andequipmentroometc.Thefloorelevationis-3.50m.Forthe8floorsaboveground,thefirstfloorisshoppingmall.Thefloorheightis6.0m.Thesecondfloorisdesignedastearoomsandprivaterooms,6.0mhigh.Thethirdfloorisusedaskitchen,privateroomsandrestaurant,5.0mhigh.Thefourthandthefifthfloorsareusedasguestrooms,meetingroomsandofficerooms,3.0mhigh.Thesixthandtheseventhfloorsareusedusguestroomsandmeetingrooms,3.0mhigh.Theeighthfloorismulti-functionalhallandwarehouse,3.0m.Pleaseseethedetailedlayoutasintheengineeringdrawing.Waterissuppliedbymunicipalwatersupplyingnetwork,withyearlyaveragepressure0.3Mpa.Thewatersupplysystemisdesignedaszonewatersupply.Thelowzonesarefromthefirstfloorundergroundtothethirdflooraboveground.Thehighzonesarefromthefourthfloorabovegroundtotheeighthflooraboveground.Watersupplyforboththelowzonesandthehighzonesarebywaterpumpandwatertank.Firecontrolsystemadoptsthecombinationofthefirehydrantsystemandtheautomaticsprayfirefightingsystem.Forthefirehydrantsystem,thepipesaresetasrings;twowaterpumpadaptersaresetoutsideofthebuilding.Whenthereisnotenoughwater,watercanbesuppliedbyfirefightingtrucksthroughwaterpumpadapters.Fortheautomaticsprayfirefightingsystem,independentautomaticwetpipesprinklersystemisadopted.Thissystemcanextinguishfireintime,andisofhighefficiency.Buttherearedisadvantagesinthissystem.Sincewhentheconfinedwaterinthepipenetworkleaks,itwillaffectanddamagethebuilding.Becauseofthefunctionsofthebuilding,centralizedhotwatersupplyisadopted.Devicesandequipmentscanbeheatedatthesametime,whichmakesmaintenanceandmanagementeasy.Theheatingequipmentisofhighefficiencyandthecostofhotwaterislow.HeatingdevicesandIIIequipmentsdonothavetobesetwherehotwaterisneeded.Itcanthussaveplaceandmakeitconvenienttouse.Forthewaterdrainagesystem,itisdesignedascombinedsewageandwastewaterdischarge.Thewasterwaterintheundergroundfloorofthebuildingisdischargedseparatewithwaterinotherfloors.Foreachverticaldrainingpipe,ventstackissetatthetopofthebuilding.Forthestormwatersystem,outsidestormsystemisadopted.Thereissinglerainstrainer,anditis“87”type.Thematerialisplastic.Keywords:watersupplysystem,firehydrantsystem,automaticsprayfirefightingsystem,hotwatersystem,waterdrainagesystem,stormwatersystem.IV目录摘要................................................................IAbstract...........................................................II第1章工程概况....................................................11.1设计依据......................................................11.2原始材料......................................................11.3设计内容......................................................1第2章室内给水系统................................................32.1给水方式的选择................................................32.2给水系统的分区................................................82.2.1给水系统竖向分区的必要性...................................82.2.2给水系统竖向分区的要求.....................................82.2.3本建筑给水竖向分区.........................................82.3室内给水系统组成..............................................82.4给水管道设备安装要求..........................................82.5增压设备及其构筑物............................................9第3章室内外消防系统.............................................103.1消火栓给水系统...............................................103.1.1消火栓给水系统说明........................................103.1.2室内消火栓方案选择........................................103.1.3消火栓给水系统的组成......................................123.1.4室外消火栓系统............................................133.1.5消防管道布置..............................................133.1.6消火栓布置................................................143.2自动喷水灭火系统.............................................143.2.1自动喷水灭火系统说明......................................153.2.2自动喷水灭火系统的组成....................................173.2.3自动喷水灭火系统管道设备安装要求..........................17第4章热水系统...................................................184.1热水系统设计说明.......
