某银行金融中心建筑给排水工程设计 摘要 此设计主要任务是某银行金融中心建筑给水排水工程设计，设计的主要内容有：建筑给水系统、建筑排水系统、消火栓给水系统、自动喷淋系统和建筑雨水系统的设计。 本建筑总共25层，建筑物总高为99.5m。 市政给水管网提供的资用水头为0.40MPa ，通过技术经济比较，室内给水系统拟采用分区给水方式。初定该建筑给水系统分两个区：一至四层为低区，由市政管网直接供水；五层至设备层做为高区，由一楼生活水池加压供水。 建筑排水系统是采用合流制，所有的污废水通过化粪池处理后排入下水道。 建筑雨水系统是采用内排水方式排水。 消火栓给水系统分室内消火栓给水系统和室外消火栓给水系统两种，消火栓布置范围包括各楼层、消防电梯前室和屋顶检验用的。消火栓的保护半径为23m。 建筑内喷头数量约6525个，设10组湿式报警阀，报警阀后管网为枝状网，每层设水流指示器。 关键词：建筑给水系统，排水系统，消火栓系统，自动喷淋系统 Abstract The main task of this design is the water supply and drainage design of finance bank. The content of my design includes the design of the building water supply system, the building water drainage system, the building storm-water system, the hydrant water supply system and the automatic sprinkler system. The building has 25 floors overground. The height of the building is 99.6m.The first～the forth floor are used for business. The fifth floor～the twenty-fifth floor are used as the big space office. The municipal water supply piping can provide 0.40Mpa head. After the comparison of technicality and economy, interior water supply system intends to adopt subarea water supply. Preliminary study out that building water supply system is divided two areas: 1～4floors are low area. The pipe network supplies water directly from municipal water supply piping;5～equipment floors are high area. Water supply is supplied by no negative pressure water equipment. The building water sewerage system adopt confluence .All waste water enter drain via a septic-tank. The building storm-water system adopts inner draining. Hydrant water supply system includes interior hydrant water supply system and outside hydrant water supply system. Hydrant arranging range includes every storey, the room in front of fire elevator and roof for check. The hydrant protects a radius of 23m. The number of sprinkler heads in the building is about 6525. The automatic sprinkler system set up 10 groups watery alarm valve. Behind the alarm valve, the piping is set as branch. Every storey se
