摘要
通过分析各消防系统组合方案特点以及国内外已通车运营的水下隧道消防配置现状,结合城市交通隧道设计案例,得出城市二类水下隧道车行道区域内消防系统采用灭火器+消火栓系统+泡沫-水喷雾灭火系统方案,并阐述了南昌市艾溪湖隧道消防及排水系统设计参数。针对隧道消防及排水实际设计中的几个关键性问题进行探讨,提出了城市二类水下隧道车行道区域内消防系统的推荐配置方案、消火栓箱设置间距确定以及隧道排水原则与要求,可为类似水下隧道工程设计提供经验和参考。
Based on the analysis of the characteristics of various fire control system combination schemes and the current situation of fire control configuration of underwater tunnels that have been in service at home and abroad,combined with urban traffic tunnel design cases,the fire control system scheme by fire extinguisher+fire hydrant system+foam-water spray fire extinguishing system in the vehicular lane area of Class II underwater tunnel in the city is obtained.The design parameters of fire control and drainage system of Aixi Lake Tunnel in Nanchang are ex-pounded.Several key problems in the actual design of tunnel fire control and drainage are discussed to propose the recommended configuration scheme of fire control system,the determination of the spacing of fire hydrant boxes and the principles and requirements of tunnel drainage in the same area,which can provide experience and reference for similar underwater tunnel engineering design.
