水下长大隧道消防灭火系统设计探讨

The discussion of the firefight system in long underwater tunnels

调查了国内外水下隧道水消防灭火系统的设置情况,提出了我国水下长大隧道灭火器、消火栓、自动喷水灭火系统等的选择策略,就消防水源选择、水量确定、管网布置等问题对消防供水系统进行了讨论,并结合某水下隧道工程情况进行了实例分析。在此基础上对我国水下长大隧道的消防系统设置提出对策建议。

Surveys the fire extinguishing system of underwater tunnel in China and other countries, recommends selection strategy about fire extinguisher, water hydrant, automatic wa- ter sprinkler system in long underwater tunnel. The determina- tion of fire water source selection, volume decision and network layout were discussed. Taking an underwater tunnel construc- tion as example, the case study was conducted. Based on the a- nalysis, suggestions about the fire system design of underwater tunnel in China were made.
