摘要
通过归纳各常用规范对城市隧道消防水系统种类配置要求,对比城市隧道常用的消防水系统,包括消火栓系统、水喷雾系统、固定式水成膜系统以及泡沫-水喷雾系统的灭火机理、灭火经济性、灭火效率以及现有隧道所配置的消火水系统案例,提出不同隧道类型应配置的消防水系统种类以及设置要求。同时基于某二类城市隧道实际工程案例,提出一种新的基于消防水池供水方式的隧道内外消火栓系统设计方案,为以后城市隧道市政供水不满足隧道内外消火栓用水需求时提供参考。
This paper summarizes the requirements of various common specifications for the type and configuration of fire water systems in urban tunnels.Compares the fire extinguishing mechanism,fire extinguishing economy and fire extinguishing efficiency of the fire water systems commonly used in urban tunnels,including fire hydrant system,water spray system,fixed water film-forming system and foam water spray system,and combines the fire water systems configured in existing tunnels.Put forward the types of fire water systems and setting requirements for different tunnel types.At the same time,based on the actual engineering case of a Class II urban tunnel,a new design scheme of the fire hydrant system inside and outside the tunnel based on the water supply mode of the fire pool is proposed,which provides a reference for the future when the municipal water supply of the urban tunnel does not meet the water demand of the fire hydrant inside and outside the tunnel.
