1、摘要本设计是某二十三层商住楼的建筑给排水设计，主要包括建筑给水系统、建筑排水系统、消防系统、自动喷淋系统等四部分设计。给水系统分为三个区供水：地下一层至四层为低区，由市政管网直接供水；五至十四层为中区，十五至二十三层为高区，由无负压设备供水。排水系统采用的是雨污分流、污废分流制，雨水直接排入市政雨水管网，卫生间污水经化粪池处理后排入市政污水管网，厨房废水经隔油池处理后排入市政管网；1-4层排水立管设伸顶通气,5-23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。消火栓系统不分区，采用S
2、N65型消火栓。自喷系统，-1层至23层设自喷系统，-1层采用中危Ⅱ级标准，其他采用中危Ⅰ级标准。自喷系统与消火栓系统合用消防水箱。给水管材根据需要，1-4层卫生间采用塑料管（PPR），住宅给水干管采用薄壁不锈钢管，从立管至各住户的给水管采用铝塑复合管。排水采用PVC-U管，同时在穿墙处设阻火圈，在出户管相连处设一定的消能措施。消防系统采用镀锌钢管。关键词：高层建筑，给水系统，排水系统，消防系统，自动喷淋系统VIIABSTRACTThisdesignisatwenty-threestoreyresidential
