The tunnel is used as an important component of road traffic, the safety of tunnel operation is related to personal and property safety, and the safety operation is more and more emphasized. One of the main factors influencing the safe operation of the tunnel is the fire safety of the tunnel. The tunnel is different from a common structure, has the characteristics of strong sealing property, deep burying, only two-end outlets and the like, and can cause great economic loss and casualties if a fire disaster is not put out in time, so that the fire fighting work of the highway tunnel is very important.
At present, the fire control measures for the highway tunnel mainly have two ideas, one is to take positive measures to prevent the tunnel from generating fire from the source, such as speed limit, dangerous carrying vehicle restriction and the like, and the other is to take measures to put out the fire in time after the fire occurs, such as tunnel fire extinguishers, fire hydrants, fire fighting fleets and the like. The former measure adopts active fire prevention, has large application limitation and low specific operability, and can not completely stop the fire in the tunnel, so that the active measure is adopted to timely extinguish the fire once the fire occurs. According to relevant standards, fire fighting measures are mainly provided with fire extinguishers, fire hydrants and other common fire fighting equipment, the standard interval of the fire hydrants is 50m, full coverage of a tunnel cannot be realized, and fire fighting blind spots which cannot be reached by fire fighting facilities inevitably exist.
The tunnel fire mainly refers to the condition that a car traffic accident or a fire caused by car burning is caused, the fire condition is developed rapidly, and the fire fighting easily misses the best time for fire fighting if the fire point is slightly far away from fire fighting facilities under the condition that the time for fighting the fire is required to be delayed for seconds when the fire happens. Especially, in case of a fire disaster, traffic jam in the tunnel is caused, and even if a fire fighting fleet is equipped, the fire fighting fleet cannot reach the fire source quickly to extinguish fire and rescue in time. And once a fire disaster occurs in the highway tunnel, toxic and harmful smoke often penetrates the tunnel, electric power and communication are interrupted, fire fighters are difficult to master the fire disaster situation in the tunnel, and manual fire extinguishing and fire rescue are difficult to implement.
