毕业设计（论文）西宁市湟水花园小区5楼给排水工程设计.doc

设计总说明 随着国民经济的发展，人民居住理念的变化，高层建筑如雨后春笋般，越来越多的矗立于城市之中。本设计是西宁市湟水花园5号住宅楼的建筑给排水设计，住宅楼总高18层，地上17层，地下1层，屋面标高为51.7米。主要包括给水系统、排水系统、消防系统和屋面雨水系统四个部分。 给水系统采用分区供水，1-7层为低区，由市政管网直接供水。8-17层为高区，采用下行上给的无水箱供水方式，由地下室的供水泵直接供水；排水系统采用的是污、废合流制，底层单独排水，排水立管仅设伸顶通气管，污水再经化粪池处理后排向市政污水管网；消防系统设计成消火栓灭火系统，火灾初期10min的水由消防水箱供给，正常供水由消防水泵从贮水池内抽取；雨水采用的是内排水系统，雨水直接排向市政污水管网。给水管采用PVC管，排水管和雨水管均采用UPVC管，消防系统采用镀锌钢管。 设计过程进行了各系统方案的确定、平面布置和计算以及各种设备的选型。最后用CAD绘制了各个系统的平面施工图和系统图。 总之，住宅给排水系统看似简单，但它与我们的日常生活息息相关。作为工程设计人员，应本着技术、安全、经济性原则，在实践中努力创新，寻求最佳的给排水设计方案，适应住宅设计发展的新要求，满足人民群众的要求。  Specification With the development of the national economy and changes in the concept of people living, the high-rise building soars everywhere in the city more and more. This design is the water supply and drainage design of ruijing Garden No.8 residential building in xiningcityThis residential building overall height total height19,on the ground 18, underground 1layer, roof height of 50.4metres.
