ABSTRACT

With the development of technology and transportation industry, long tunnels have become commonplace in the construction of highways and railways. At present, the fire-fighting measures for the long tunnel still remain in the use of hand-held chemical fire extinguishers and erected fixed-line water pipes for firefighting. Rescue and escape conditions are both large and insufficient. In view of the shortcomings of traditional tunnel structural components such as poor fire resistance, old fire extinguishing methods, poor escape conditions and rescue difficulties, this paper proposes a long tunnel fire protection system that intelligently monitors fire sources and extinguishes fires. The system uses the refractory ceramic mixture as the inner arc plate material of the tunnel, adopts the linear moving fire source detection system and takes into consideration the tunnel smoke extraction, and can improve the internal air environment of the tunnel while achieving the intelligent fire protection effect. It also provides sufficient time for personnel to escape and rescue. The proposed system aims to provide a theoretical reference for the construction of future tunnels.
