1、嘉兴学院本科生毕业论文（设计）摘要：本设计为位于浙江嘉兴的办公楼，有地上九层办公楼和一个地下室。采用分区给水，地下室到六层为地区，市政管网直接供水，七层到九层为高区，选择无负压设备供水。室内给水使用PP-R管材。建筑内部采用污废分流制排水，一层污水单独排出，防止正压喷溅。生活污水先经化粪池局部处理后排入市政排水管道。为使生活污、废水管内气体流通，压力稳定，排水立管顶端应设伸顶通气管。室内排水管采用UPVC管材。本建筑由于层数多，室外管网不能满足供水压力，采用设水泵和水箱的消火栓给水方式消火栓设计流量20L/s，同时使
2、用消防水枪4支，每根竖管最小流量10L/s。水枪喷嘴口径取19mm，水带口径选择65mm，充实水柱取12m。室内消防给水管采用普通焊接钢管。鉴于本建筑位于嘉兴，采用湿式喷淋灭火系统，采用热镀锌普通焊接钢管。室外雨水管网位于建筑物的南侧，埋深2米，管径600mm。管材为加筋UPVC管。屋顶有排水檐沟，雨水由屋顶雨水口经雨水立管排至地下，汇集以后再由室外雨水管排出，污废水与雨水分流。关键词：建筑给排水；消防；喷淋；雨水；冷凝水。VII嘉兴学院本科生毕业论文（设计）Abstract：Thedesignforthebuild
