城市轨道交通给排水设计要点

Key Points of Water Supply and Drainage Design of Urban Rail Transit

以深圳地铁6号线光明新城站为例,对不同水源情况下标准高架地铁站的消防给排水设计进行分析。重点阐述两路水源、单水源及无水源条件下的给水系统、消防系统所采用的供水方案,并总结废水排水、雨水排水的设计要点及创新点。车站小型商铺区(总建筑面积<1 000 m^(2))采用了局部自动喷水灭火系统进行保护,扩展讨论车站主体设置自动喷水灭火系统的要件。

In the case of Guangming Xincheng Station for Shenzhen Metro Line 6,this paper analysed the design of these systems,include in water supply system,fire protection system,wastewater system and rainwater system.Under the condition of two water source,single water source and no water source,elaborated the scheme for water supply system and fire protection system,also summarized the key point and innovation point in the design of wastewater drainage and rainwater drainage.Exactly less than one thous and square meters of the total construction area belong to the small commerce area.The small commerce area is protected by the local application system of sprinkler system,and discussing the requirements for install the sprinkler system.
