Suffocation type movable tunnel fire extinguishing device

Abstract

A suffocation type movable tunnel fire extinguishing device comprises a high-temperature-resisting air bag and a movable bridge. A top beam is arranged at the upper portion of the inner wall of a tunnel. Two end beams are arranged on the top beam and are parallel. The end beams are perpendicular to the top beam. A main beam is arranged between the two end beams. The movable bridge comprises guiderails, the end beams are arranged on the guide rails and can move along the guide rails, and the high-temperature-resisting air bag is arranged on the beam. According to the suffocation type movable tunnel fire extinguishing device, the highway tunnel operation safety performance is improved, and security threats to personnel left in the tunnel and damage to tunnel electromechanical and civil engineering facilities from the fire disaster are reduced. An inflation type air bag device is adopted for sealing the tunnel sections at the two ends of a fire source, high-temperature gas and a large amount of smoke generated by the fire disaster are isolated, and fire disaster spreading and toxic gas diffusion can be effectively controlled.

Description

technical field [0001] The invention relates to the field of tunnel fire-fighting facilities, in particular to a suffocating type movable tunnel fire-extinguishing device. Background technique [0002] With the continuous improvement of my country's economic development level, a large number of mountainous roads, railways and other transportation infrastructure have been vigorously developed, which has led to an increase in the number of tunnel construction, but also brought serious traffic fire accidents. The statistical analysis of accidents in tunnels shows that whether it is ordinary roads or expressways, accidents directly or indirectly related to fire account for a very large proportion, and serious and extraordinarily serious accidents account for a very high proportion. Therefore, how to embody the guiding ideology of "people-oriented, safety first" and take effective measures to reduce or even avoid similar traffic fire accidents during the road operation period is ...

AI Technical Summary

Problems solved by technology

[0003] Due to the long and narrow space in the tunnel, the occurrence of a tunnel fire will lead to a sudden increase in the temperature in the tunnel. Due to the high wind speed in the tunnel, a large amount of smoke with toxic gases produced by the combustibles will quickly spread from the fire to the surroundings, which will not only seriously damage the The life safety of the personnel in the tunnel makes it difficult for rescue to arrive in time, and also causes serious damage to the main body of the tunnel and its ancillary facilities, causing great economic losses

[0004] Existing tunnel fire-fighting measures mainly adopt the method of direct intervention by the fire department, but it is often impossible to reach the scene at the first time when the fire occurs. In the case of a large fire, it is difficult for rescuers to enter; way, relying too much on the continuous replenishment of fire-fighting water, which will cause fatal obstacles to fire-fighting when water resources are in short supply, especially in the arid mountainous areas of the northwest, where fire-fighting water is in short supply; the practicability of setting up sprinklers is not strong, and it is difficult to ensure quality and The economic burden is serious, so it is necessary to propose a practical, reliable, economical and efficient tunnel fire extinguishing device
