摘要
目前隧道消防系统常采用高压消防系统供水。但部分山区高速公路隧道由于现场地势陡峭、地形复杂,难以找到满足修建高位水池的合适位置,现场施工材料运输非常困难,现场管道安装难度大,高位水池高程难以满足要求,若采用高压消防系统供水则有很大难度。介绍一种新型稳高压给水系统,其是利用取水设施将水引至低位水池,通过加压泵将低位水池流入的水直接加压供给隧道内消防管网,不仅可解决常高压消防系统不能修建高位水池、外场管道安装难度大等困难,而且还可降低成本,增加系统的稳定性。
At present the tunnel fire extinguishing system usually adopts high- pressure fire fighting system to supply water. However,appropriate positions that satisfy construction of high pools are difficult to find for part of expressway tunnels in mountainous area for abrupt terrain and complicated landform on site,transportation of construction materials to site is very difficult,installation of site pipelines faces great difficulty,the elevation of high pools cannot satisfy the requirements,so high- pressure fire extinguishing system adopted to supply water is quite difficult. This paper introduces a new stable high- pressure water supply system,which utilizes water intake facilities to introduce water to low pools,and pressurizes water from low pools directly via booster pumps and supplies for firefighting pipe networks in tunnels. The system can not only overcome difficulties that high pools cannot be constructed in constant high- pressure fire extinguishing system and installation of offsite pipelines faces great difficulty,but also reduce the cost and increase stability of the system.
