Background

China has drawn attention in the construction fields of highway tunnels, urban road underground passages and the like, and has become the world with the most tunnel and underground engineering, the most complex and the fastest development speed. Road tunnels have been moved from heavy dunes to deep mountains, from land to underwater, and from suburbs into cities. The tunnel is also longer and wider, the line shape and the structural style of the tunnel are more colorful, and the forms of the spiral tunnel, the small clear distance tunnel, the multiple arch tunnel, the bifurcation tunnel and the like are derived. The systems for ventilation, lighting, monitoring, power supply and distribution, fire fighting, escape and rescue, etc. required by the operation of the facilities in the tunnel are increasingly complex. Meanwhile, as the driving in the tunnel is influenced by complex factors such as space, light environment, sight line, abnormal psychology and behavior of drivers and the like, various traffic accidents are easily induced; at present, the production and transportation management of dangerous chemicals in China does not completely reach the source-related radical treatment, and certain loopholes exist in the production and inspection of special vehicles. All the problems are that the spontaneous combustion of the automobile engine in the tunnel, the ignition of tires, the ignition of accident collision, the leakage, combustion and explosion of goods, particularly dangerous chemicals, the fire caused by electric line faults and other reasons are more and more, and the prevention is not sufficient. The tunnel is a special tubular structure, is fundamentally different from a common open road section, has the characteristics of closure, complexity, difficulty in connection and rescue and the like, and belongs to a special road section. The tunnel fire disaster has unpredictability, diversity and uncertainty of height, the tunnel can be used as a closed space, the temperature can be rapidly increased to more than 1000 ℃ within 2-10 minutes after the fire disaster occurs, the fiery airflow is spread rapidly along the wind, vehicles in the tunnel are difficult to evacuate, and therefore more vehicles are ignited due to the development of the fire along the traffic flow. Once a fire disaster happens in the tunnel, the damage is extremely large, and the life and property safety of people and the tunnel structure in the tunnel are greatly damaged.

Therefore, a tunnel fire-fighting system is needed urgently, rainwater and the like cannot be collected and applied to tunnel fire-fighting generally, waste is caused, fire positions cannot be detected for directional fire extinguishing mostly, waste of water resources is caused, and the using effect is poor.
