1、东北石油大学本科生毕业设计（论文）摘要本设计是太原市联通新苑建筑给水排水系统设计，主要包括建筑内部给水系统、建筑内部排水系统、建筑内部消火栓系统、自动喷水灭火系统、建筑雨水排水系统、热水给水系统等六部分设计。建筑内部给水系统分为三个区供水。地下一层至三层为低区，由市政管网直接供水；四至十七层为中区，十八至三十层为高区。排水系统采用的是污废合流制，污水经化粪池处理后排入市政污水管网；1-3层排水立管设伸顶通气,4-30层排水立管设有专用通气立管。消防系统分消火栓系统和自动喷淋灭火系统两部分。消火栓系统分高区和低区，需减压的部分采用SNJ65型减压稳压消火栓，其余采用SN65
2、型消火栓。负一层至3层设自动喷水灭火系统，采用中危1级标准。自动喷水灭火系统与消火栓系统合用消防水箱。给水管材根据需要，一二三层卫生间采用塑料管（PPR），住宅给水干管采用薄壁不锈钢管。排水管均采用铸铁管，同时在穿墙处设阻火圈。消防系统采用镀锌钢管。室外给排水系统根据需要设置管道、检查井等。关键词：给水系统;排水系统;消防系统58东北石油大学本科生毕业设计（论文）AbstractThedesignisacomplexconstructionthirtyfloorwatersupplyanddrainagedesign,includingwatersupplysystems
