The fire extinguisher, the fire hydrant (or the foam fire hydrant), the foam-water spraying system are applied to a part of long and large underwater tunnels more frequently, the system belongs to an automatic fire extinguishing system, and the fire disaster is quickly suppressed by means of double effects of foam and water film forming, a combustion surface is cooled, fuel oil is isolated from air, and the system has a good effect of extinguishing oil fire disasters in the tunnels. However, the system has the problems of leakage, difficulty in maintenance, difficulty in maintaining foam pressure and the like. Because the pipeline of the foam-water spray combined fire extinguishing system is complex, and the corrosion condition of foam to the pipeline is also complex, leakage conditions of different degrees exist at the joints of the foam pipelines of each tunnel, the foam pipelines are not easy to repair, and the spray heads are easy to corrode and block. In addition, the system is easy to generate misspraying, and the foam expands when meeting water and is accumulated on a lane, so that the cleaning is difficult, on one hand, expensive foam liquid is wasted, and on the other hand, pollution and corrosion are caused.
So far, China has not established a set of engineering construction standards for road tunnel fire protection design and construction of a comprehensive system, and major casualties can be caused once a fire disaster occurs in an urban road tunnel. More seriously, it may result in structural collapse, leading to more serious water damage and significant economic loss.
