摘要:拟建建筑为一幢十六层的综合性商住楼。地下一层为车库，一到二层为商铺，三到十六层为住宅，裙房的一二层为商铺，三层为办公区。该工程的给水排水设计主要包括生活给水设计、消防给水设计、排水设计、雨水设计和热水设计。其中，生活给水设计包括给水方式的选择、给水管径和水泵计算和选择。本设计生活给水系统共分三个区，一到三层为低区，四到十三层为中区，十四到十六层为高区。采用水泵水箱联合供水的方式。给水管材采用钢塑符合管。排水包括排水管道的计算和排水管道的布置，屋顶雨水排水系统，生活污水的局部处理等设计项目。雨水和污水分流排放。雨水和污水分别设置立管，生活污水收集到化粪池，经过简单处理后排入市政管网，雨水、废水直接排入市政管网。排水管材采用UPVC管。雨水系统采用重力无压流普通檐沟外排水系统，雨水沿屋面集流至檐沟，然后流入设置的立管排至室外地面。本建筑防火等级不低于一级，高度小于一百米，故消防给水系统不分区，采用临时高压给水系统。消防管道采用钢管，连接方式为卡箍连接。本设计采用不过湿式喷水灭火系统，系统末端设置末端试水装置。自喷立管选用DN100镀锌无缝钢管。热水系统为集中热水供应系统，分为三个区，一到三层为低区，四到十三层为中区，十四到十六层为高区。低区由市政管网直接供水，中区和高区由屋顶水箱供水。

Abstract:Proposed architecture for a 16 layer integrated mass. Garage for the underground layer, one to the second floor for shops, 3 to 16 layer for residence, a podium for shops on the second floor, third floor is for office area. The project of water supply and drainage design mainly includes the life water supply, fire water supply design, drainage design, rain water and hot water. Among them, the living water supply design includes the choice of the ways of water supply, water supply pipe diameter and the pump calculation and choice. This design the drinking water system is divided into three areas, one to three layers of low area, four to thirteen layer for the central district, 14 to 16 layer is high area. With the method of pump tank joint water supply. Water supply pipes adopt gangsu tube. Drainage including calculation of drainage pipes and drainage pipeline arrangement, roof rainwater drainage system, sewage of local processing and other design projects. Rain and sewage diversion discharge. Rainwater and sewage set riser respectively, sewage collected from septic tanks, through simple processing back into the municipal pipe network, rainwater, wastewater is directly discharged into the municipal pipe network. Drainage pipe adopts the UPVC pipe. Rainwater drainage system by gravity free surface flow ordinary eaves gutter drainage system, rain water collecting to eaves gutter, along the roof and then flows into the setting of the riser to the ground outside. The building fire rating not less than level 1, less than one hundred meters high, so the fire water system partition, use temporary high pressure water supply system. Steel pipe, fire control pipeline in a connection way as the clamp connection. This design adopts wet sprinkler system, however, that system terminal end of the test device. Flowing the riser choose DN100 galvanized seamless steel pipe. Hot water system for centralized hot water supply system, divided into three areas, one to three layers of low area, four to thirteen layer for the central district, 14 to 16 layer is high area. Directly by the municipal pipe network water supply low area, central area and high by roof water tank water supply.
