Abstract

In order to solve the problem that fire spreading is difficult to control and oxygen deficiency in a tunnel is insufficient when a fire disaster occurs, the invention provides a tunnel fire extinguishing system. The system mainly comprises a high-position water pool, a water supply pipeline located at the top end of the interior of the tunnel and a water supply air guide pipe connected with the portion between the high-position water pool and the water supply pipeline, wherein the high-position pool is located above the tunnel, a plurality of spray heads uniformly arranged along the length direction of the tunnel are connected to the water supply pipeline, a plurality of air guide pipes are arranged on the water supply air guide pipe, and a one-way valve used for controlling fluid to be only fed is arranged in the water supply air guide pipe.

Description

technical field [0001] The invention relates to the technical field of tunnel fire extinguishing, in particular to a tunnel fire extinguishing system. Background technique [0002] Due to the low altitude and poor ventilation conditions inside the tunnel, when a vehicle collides inside the tunnel and causes a fire, although the fire can be extinguished through the existing automatic sprinkler system, during the fire, the oxygen inside the tunnel However, as the temperature continues to rise, the pressure inside the tunnel also continues to rise, making it difficult for outside air to enter, and the trapped people in the tunnel face the danger of hypoxia and suffocation. Contents of the invention [0003] In order to solve the problem that the fire in the tunnel is difficult to control and the oxygen in the tunnel is insufficient, the present invention provides a tunnel fire extinguishing system, and the adopted technical scheme is as follows: [0004] A tunnel fire exting...
