办公楼给排水毕业设计

西安市商务大厦建筑给水排水设计西安建筑科技大学环境与市政工程学院给水排水工程2007届郭兴宇指导教师王俊萍摘要：商务大厦位于陕西省西安市，是集商务、办公、住宿、餐饮、娱乐于一体的综合大楼。该建筑有地下一层，设水泵房、空调机房、柴油机房、变电间、六级人防等，地上十八层；屋顶有电梯机房和水箱间。一层为大堂、商务、餐厅、设消防控制室；二层为商务、办公、餐厅；三层设会议、办公、多功能厅等；四、五层为商务、娱乐用房；中间有设备层；六至九层为客房每层20套；十至十一层设客房套房，每层10套；十二至十八层为办公用房；屋顶设电梯机房和水箱间。设计本着“技术先进、经济合理、安全适用，保质保量”的原则，注重设计的高效、节能、环保、智能化的要求来完成建筑室内给水、排水、热水、消防的设计。商务大厦生活给水系统竖向分两个区。地下一层到五层为低区，由市政管网直接供水，采用下行上给式；六层到十八层为高区，由地下室水泵和屋面水箱联合供水，也采用下行上给式。高区的底部几层的横支管上设减压阀，使底部的用水压力满足要求。商务大厦热水给水方案采用集中二次加热，换热器下置，闭式，下行上回，同程式，干管机械循环。大厦的热水管网仍采用下行上给的供水方式，与大厦冷水供水管道布置保持一致。商务大厦属于一类建筑。室内消火栓系统采用设水泵、水箱的给水方式。高位消防水箱内贮存火灾初期10min的用水量，地下室的水泵间内设两台消防水泵，一用一备。大厦周围设三个地上式水泵结合器。大厦为中危险级一级。除了地下室采用直立型喷头外全部用下垂吊顶型喷头。有三个湿式报警阀组控制全楼的喷头。竖向不分区，但在底部几层的自喷横管上设减压孔板，防止系统局部超压。生活污、废水用合流制收集。采用仅设伸通通气管通气。雨水系统考虑到建筑外观的要求，用单斗式内排水。关键词：高层建筑，综合楼，给水排水，工程设计ABSTRACTThisengineeringisaboutwaterandwastewaterahighriseandmultiple-usebuilding,whichlyingonxi’ancity.Ifpressesitshighdemarcation,thisbuildingbelongtohighbuilding,which76.4meters.Inthebuilding,the1stfloortothe5thfloorareemporia,the6thfloortothe11thfloorareguesthousesandthe12thfloortothe18thfloorareoffice.Inthedesign,themaincontentsincludethewatersupplysystem,hotwatersystem,andthefirefightsystemdesignwithdrainsystemwhichincludethedomesticwastewaterandtherainwater.Inaddition,thedomesticwatersupplysystemispumpedbyautorhythmpumpinverticaldivisionblock:Itadoptinthehotwatersystemconcentrationheattheway,machinecirculating,thehydrantsystemandautomaticfireextinguishingsystemarebothsecondarypressureboosting.Rainwateradoptionthewaythatgravityinsidedrainejectsthehouserainwaterintime.Besides,theengineeringincludesdistrictwaterandwastewater.Forexample,thedesignsforpumpbuildingandsoon.Keywords:highbuilding,multiple-usebuilding，buildingwateranddrains,目录第一章绪论....................................................1第二章设计说明................................................22.1生活给水系统设计说明..........................................................................22.1.1系统选择........................................................................................................22.1.2给水管道的布置与敷设要求..................................................................22.1.3方案确定........................................................................................................32.1.4系统的组成...................................................................................................42.1.5给水系统图示...............................................................................................42.2热水给水系统设计说明..........................................................................42.2.1热水供应类型选择.....................................................................................42.2.2竖向分区........................................................................................................52.2.3热源的选择...................................................................................................52.2.4水的加热方式...............................................................................................52.2.5加热器的放置...............................................................................................62.2.6热水供应系统的加热设备和器材........................................................62.2.7热水管道的布置与敷设...........................................................................72.2.8热水供水系统方案的确定.......................................................................72.2.9热水系统图示...............................................................................................72.3室内消火栓给水系统设计说明..............................................................82.3.1系统参数确定...............................................................................................82.3.2系统组成........................................................................................................92.3.3消火栓给水系统的布置...........................................................................92.3.4消火栓给水系统的给水方式的确定..................................................102.3.5系统的竖向分区........................................................................................102.3.6消火栓给水系统图示..............................................................................112.4自动喷水灭火系统设计说明................................................................122.4.1参数确定......................................................................................................122.4.2喷头的选择.................................................................................................122.4.3喷头的布置.................................................................................................122.4.4湿式报警阀的确定...................................................................................122.4.5自动喷水灭火系统的组成.....................................................................132.4.6自动喷水灭火系统图示.........................................................................132.5屋面雨水排水系统设计说明................................................................142.5.1建筑屋面雨水的排放方式的比较......................................................142.5.2建筑屋面雨水的排放方式的确定...................................
