XXX大厦给水排水设计摘要：本设计题目为南京双色大厦给水排水设计，本设计完成该建筑的给水、排水、消火栓、自动喷淋、热水、雨水六大系统的设计。 给水系统：从供水安全、经济合理、技术可行方面综合考虑，确定给水方式为变频调速给水系统与气压水罐组合供水。给水管网采用下行上给式，本设计确定了分区范围、给水管材、管道敷设方式以及设备型号。 排水系统：本设计进行了排水体制、排水方案的确定；排水管道系统的布置；排水管道水力计算以及通气管的计算；卫生洁具的选型及布置；化粪池选型；排水管材的选择、地下集水井的容积以及潜污泵的型号。 消火栓系统：根据高层综合建筑的消防用水量进行了分析和探讨；确定了消火栓的数量以及消火栓的安装高度和设置位置。并对消防水箱、消防水池的容积进行了确定。 自动喷淋系统：确定了喷头类型以及布置形式；进行了自动喷淋管网的水力计算；报警阀、水流指示器的选型。 热水系统：根据高级旅馆的热水供应要求，本设计采用立管循环，在回水管上设置循环泵。进行了热水量、耗热量、热媒耗量的计算、选择了半容积式加热器作为加热设备。分别进行了热水配水管网、热水回水管网的水力计算，以及保温材料的选择。 雨水系统：进行了雨水量的计算，划分了汇水面积，确定了雨水斗的型号以及连接管、悬吊管、立管、排出管的管径与材料。关键词：高层建筑；给水系统；排水系统；热水系统；消防给水系统；雨水系统ABSTRACT The subject of the design is water supply and drainage of the shuangse building in Nanjing. The design of the building includes water supply, drainage, fire hydrants, sprinkler, water, and rain water system.. Water supply system: Considering aspects of thesecurity of water supply, reasonable economy, technical feasibility，the water supply chooses frequent conversion water supply system with air pressure tank.Water supply network is from downside to type on, and the design to determine the partition range, water supply pipe, pipe laying method and the device models. Drainage system: The design includes the determination of the drainage system and program, discharge pipe system layout, pipes hydraulic calculation and the calculation of snorkel, selection and arrangement of sanitary wares,septic selection, the choice of drainage pipe ,the volume of underground catchpit submersible sewage pumps, as well as models. Fire hydrant systems: According to analyzed and discussed the fire water of high-level comprehensive building, this design determines the number of the fire hydrant and fire hydrant installation height and location, and also determines the volume of fire water tank and fire pool. Sprinkler systems: This design determined the nozzle type and arrangement forms, did the hydraulic calculation of the sprinkler pipe network, selected alarm valves and water flow indicators
