城市二类交通隧道排水及消防系统设计探讨

Discussion on the design of drainage and fire protection system for urban classⅡtraffic tunnel

通过对比分析各消防系统,结合城市交通隧道设计案例,得出城市二类隧道内消防系统采用固定式水成膜消防系统、消火栓系统、灭火器三种消防灭火系统组合的消防系统,工作井设备用房设气体灭火系统及灭火器,并阐述了消防系统设计参数。对隧道排水系统进行了探讨,提出了最低点废水泵房废水通过工作井废水泵房转输的方案,分析归纳了雨水泵房设计参数。

Through the analysis of each fire protection system,and combined with the urban traffic tunnel design case,it is concluded that the fire protection system in the urban classⅡtraffic tunnel adopts the combination of fixed water film fire protection system,fire hydrant system and fire extinguisher.The equipment rooms in the working well are equipped with gas fire extinguishing and fire extinguisher,and the design parameters of fire protection system are expounded.This paper discusses the drainage system of tunnel,puts forward the scheme of transferring the waste water from the lowest waste water pump room through the working well waste water pump house,and analyzes the design parameters of the rain pump house.
