太行山特长隧道消防供水系统设计

Design of Taihang tunnel fire water supply system

太行山特长隧道作为拟建项目昔榆高速公路的特大控制性工程,保证其安全可靠地运营至关重要。针对隧道长距离、大高差的特点,探讨了其消防供水系统的设计难点,分析了消防管网超压的原因,提出了减压水箱+减压阀组合分区的解决方案,论述了太行山隧道地上式高位水池的防冻保温设计新方案。

As a huge control project of Xiyu expressway,it is very important to ensure the safe and reliable operation of the Taihang tunnel.According to the characteristics of long distance and large height difference of the tunnel,this paper probes into the design difficulties of its fire water supply system,analyzes the causes of overpressure of firefighting pipe network,and puts forward the solution of the combination zoning of pressure-reducing water tank and pressure-reducing valve.In addition,the paper discusses a new design scheme of freezing prevention and heat preservation for the above ground type high level water tank of Taihang tunnel.
