摘要
分析铁路隧道的火灾危险性及隧道内灭火设施的优缺点,指出细水雾在铁路隧道救援站内应用的优势,并在有纵向通风的情况下对中、高压细水雾在铁路隧道救援站内的应用进行实验对比。实验结果表明,纵向通风情况下,高压细水雾的灭火性能低于中压细水雾。给出某一具体工程案例,对细水雾灭火系统在铁路隧道救援站内的设计应用进行计算与说明,为细水雾灭火系统在铁路隧道救援站内的推广提供参考。
The fire hazards of railway tunnel were analyzed and the advantages and disadvantages of different fire extinguishment equipment were analyzed too.The advantages of water mist system were pointed out,and the application of high pressure water mist and middle pressure water mist with longitudinal ventilation were compared by experiments.The results showed that under the longitudinal ventilation,the fire extinguishing performance of middle pressure water mist was better than that of high pressure water mist.A typical design of water mist fire extinguishing system in an object was calculated and explained,to give reference for the design and application of water mist system in the railway tunnel.
