小区住宅楼的建筑给水排水设计

河南城建学院本科毕业设计目录1摘要本设计是一栋小区住宅楼的建筑给水排水设计，主要包括给水系统、排水系统、消防系统、自动喷淋系统四个部分。该建筑高度76.500m，建筑总面积约30000m2。生活给水系统采用恒压变频泵给水方式。地下一层至地上六层采用市政管网供水，地上七层至二十五层采用变频泵供水。该方案供水安全可靠，投资及维护费用低。同时，水泵出水量稳定，能保持在高效区运行。排水系统采用雨水和生活排水合流排放。生活污水经室外化粪池处理后排至城市排水管网。室内消火栓系统采用水箱和水泵联合供水的临时高压给水系统，并设有消防水箱一个。消防给水系统管道采用独立设置，并且竖向成环。自动喷水灭火系统采用湿式灭火系统，因为此建筑一层为商场，所以需使用自动喷淋。该建筑全楼均设自动喷水灭火系统，采用玻璃球闭式标准喷头。该系统管道采用独立设置，并且竖向成环。消防用水来自高位水箱。关键词：建筑给水，建筑排水，消防系统，自喷系统河南城建学院本科毕业设计目录2AbstractThedesignisthefloorofthebuildingofaresidentialdistrictwatersupplyanddrainagedesign,includingthewatersupplysystem,drainagesystems,firesystems,automaticsprinklersystemfourparts.Thebuildingheightof76.500m,atotalconstructionareaof​​about30,000m2.Domesticwatersupplysystemconstantvoltagevariablefrequencypumpwatersupply.Basementtothegroundsixlayersofthemunicipalwatersupplypipenetwork,onthegroundsevento25storiesandavariablefrequencypumpwater.Theprogram'swatersupplyissafe,reliable,lowinvestmentandmaintenancecosts.Atthesametime,pumpoutthewaterisstableandcankeeprunninginthehighzone.Drainagesystemwithstormwateranddrainageconfluenceoflifeemissions.Sewageprocessingbytheoutdoorseptictankbackrowtotheurbandrainagenetwork.Thefirehydrantsystemtemporaryhighpressurewatersupplysystems,watertanksandpumpswatersupplyandafirewatertankone.Thefirewatersupplysystempipingusinganindependentset,andverticalring.Automaticsprinklersystemtowetfiresuppressionsystem,becausethisbuildingisalayerofshoppingmalls,andsoneedtouseasprinkler.Thebuildingfloorareequippedwithautomaticsprinklersystems,usingclosedglassballstandardnozzle.Thesystempipeusinganindependentset,andverticalring.Thefirewaterfromthehighwatertank.Keywords:buildingwatersupply,constructionofdrainage,firesystems,AutomaticSprinklerSystem河南城建学院本科毕业设计目录3目录第一章给水系统设计...................................................................................................51.1给水方式的确定................................................................................................51.2初步布置设备和管道........................................................................................51.3生活贮水池计算................................................................................................61.4建筑给水引入管计算........................................................................................71.5给水管网的水力计算........................................................................................91.6生活泵选型......................................................................................................151.6.1提升泵站的扬程计算...........................................................................151.6.2中区给水系统减压设计.......................................................................151.6.3校核高位消防水箱所需扬程...............................................................161.6.4变频恒压供水设备选型.......................................................................16第二章生活排水系统设计.........................................................................................172.1排水体制及通气方式......................................................................................172.1.1排水体制...............................................................................................172.1.2初定通气方式.......................................................................................172.2管材的选用及布置..........................................................................................172.3管道设计计算..................................................................................................172.4化粪池选型......................................................................................................22第三章消火栓系统设计.............................................................................................233.1消火栓给水方式..............................................................................................233.2消火栓系统的布置..........................................................................................233.3室内消火栓系统用水量水力计算..................................................................243.3.1确定室内消火栓系统用水量...............................................................243.3.2确定最不利情况下出流水枪支数及出流水枪位置...........................243.3.3确定消火栓设备规格...........................................................................243.3.4消防管道流量、管径、压力损失计算...............................................243.3.5消防水泵的计算...................................................................................293.3.6水泵接合器的选用...............................................................................293.3.7消火栓压力与减压计算.......................................................................293.3.8校核水箱安装高度...............................................................................303.4高位消防水箱的计算......................................................................................303.4.1有效容积...............................................................................................303.4.2设置高度...............................................................................................303.5消防水池的设计...................................................................
