摘要
针对目前铁路客运专线长大隧道的消防未有规范规定,通过对武广铁路客运专线大瑶山隧道群消防设计,重点从长大隧道消防系统的组成、系统的布置、设计参数选取、设备选型及控制等方面进行论述,提出长度在5 km及以上的客运专线隧道设备洞室采用脉冲式无管网超细干粉自动灭火系统,对未设防护门的设备洞室通过2组延时自动灭火装置分级灭火;对长度大于10 km的特长客运专线隧道增设水消防系统进行定点消防,可供高速铁路长大隧道消防工程设计借鉴。
At present, there is no standard code that can be used in fire extinguishing design of long and major tunnel on passenger dedicated line. This paper, in combination with the fire extinguishing design for Dayaoshan tunnel group on Wuhan-Guangzhou passenger dedicated line, emphatically expounded relevant issues of fire extinguishing design for long and major tunnels, such as the system constitution, system arrangement, design parameter selection, equipment selection and control and so on. It is suggested in this paper that： （ a ） the impulse-type pipeless superfine dry powder automatic fire extinguishing system should be employed in the equipment caverns of passenger dedicated line tunnel whose length is greater than or equal to 5Km, and two sets of delayed automatic fire extinguishing device should be used for the tunnel equipment caverns which are without protection doors, so as to put out fire hierarchically;（ b） the fire water system for fixed-point fire extinguishing should be added into the super-long tunnel whose length is more than 10Km on passenger dedicated line. All the above-mentioned measures can serve as reference for fire extinguishing engineering design of long and major tunnel on high-speed railway.
