石家庄地下轨道交通2号线给排水及消防案例优化设计

Case optimization design of water supply and drainage and fire protection of Shijiazhuang Metro Line 2

针对典型轨道交通地下线工程,以石家庄市轨道交通2号线一期工程为例,对该工程给水系统、排水系统、水消防系统及气体灭火系统的设计标准及要点进行介绍,对设计过程中遇到的难点及处理措施进行分析总结。从已运营轨道交通工程存在的不足、运营单位的特殊要求及新规范调整等角度出发,提出了在该工程建设中设计所做的优化措施,包括水箱(池)补水措施优化、污水系统排水管网及设备优化、车站市政接驳与管线改迁同步考虑及室外消防系统优化等措施,通过优化处理提升了轨道交通给排水及消防系统稳定性、安全性及经济性。

For the typical underground line project of rail transit,this paper takes Shijiazhuang Rail Transit Line 2 phase I project as an example.The design standards and key points of water supply system,drainage system,water fire fighting system and gas fire extinguishing system of the project are introduced.The designing challenges and treatment measures are analyzed and concluded.From the perspective of the drawback of the rail transit project in operation,the special requirements of the operation company and the adjustment of the new specifications,this paper puts forward the optimization measures for the project construction design.The optimization measures include the optimization of water tank(pool)replenishment measures,sewage system drainage pipe network and equipment,simultaneous consideration of station municipal connection and pipeline relocation,and outdoor fire protection system.The stability,safety and economy of rail transit water supply and drainage and fire protection system are improved via the series of optimization.
