某医院设计汇.doc

PAGE  PAGE 50 摘 要 本设计是某十四层的医院住院大楼的建筑给排水设计，主要包括给水系统、排水系统、消防系统、热水系统和屋面雨水系统五个部分。 给水系统采用分区供水，一到四层为低区，由市政管网直接供水。五层到十四层为高区，采用下行上给的供水方式，由地下室的高区供水泵供水到高区管网，并同时供给屋顶的消防水箱；排水系统采用的是污、废合流制，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和自动喷水灭火系统，火灾初期10min的水由消防水箱供给，正常供水由消防水泵从消防水池内抽取。自动喷水灭火系统开湿式自喷系统。根据报警阀组控制的喷头数的有关规定共设置四个湿式报警阀，湿式报警阀装在主楼消防泵房内，自带水力警铃报警，并有压力开关自动启动喷淋水泵。均采用68度的玻璃球喷头。 热水系统采用集中供热的热水供应方式，采用闭式热水供应系统，循环是下行下回双立管同程式全循环系统。拟采用半容积式水加热器，冷水通过加热器集中加热后，再由提升泵供向配水管网；雨水采用的是内排水系统，雨水直接排向市政污水管网。给水管和排水管均采用PVC管，消防系统管道采用给水铸铁管，热水系统都采用塑料管。 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、系统图、大样图和设计说明。 关键词：高层建筑、建筑给排水、给水管材 Abstract This design is a 14 layers buildings of the public residence building to , completing the design of the water supply system and draining the system, fire fight system, the hot water system and the system of the roof rain water. The water supply system adoption cent area supply water. 1-4 low areas of the layers is taken care of the direct water supply by the municipal pipe net. Five to 14 are the high areas under, selects water supply method which in the line gives, supplies water the high areapipe network from the basement high area water supply pump,supply and the roof while the fire cisterns. The drainage system is sewage, waste combined, drainage standpipe located only stretch top ventilator, via septic tank effluent discharged to the municipal sewer network. Fire hydrant system design into systems and automatic fire sprinkler systems.The fire initially for 10 min from the water supply tank fire, and normal water supply from fire pumps from the fire from within the pool. Automatic sprinkler systems come from the wet spray system. According to the police control the nozzle valve block several of the provisions were set up four wet alarm valve, wet alarm valve installed in the main building fire pumping station, bringing their hydraulic alarm warning, and there is pressure to switch automatically activated spray pumps. 68 degrees have adopted the glass
