Tunnel fire-fighting structure based on municipal water supply

Abstract

The invention relates to the technical field of tunnel fire fighting, and discloses a tunnel fire-fighting structure based on municipal water supply. The tunnel fire-fighting structure comprises a tunnel body, a supporting roadbed is fixedly connected in the tunnel body, a second lane is arranged on the upper surface of the supporting roadbed, a first lane is arranged at the bottom of the tunnel body, supporting walls are fixedly connected to the two sides of the first lane and the two sides of the second lane correspondingly, exhaust channels are arranged between the two supporting walls on the same side and the tunnel body correspondingly, and two supporting columns are fixedly connected to one sides of the two supporting walls on the other side correspondingly. According to the tunnel fire-fighting structure, large-range fire extinguishing can be conducted in a tunnel, the phenomenon that fire behaviors of firefighters cannot be controlled within the police time range is avoided, meanwhile, when the fire behaviors cannot be controlled, people can escape in time and be prevented from being hurt, dense smoke in the tunnel body can be exhausted, and the smoke is prevented from influencing escape and safety of people.

Description

technical field [0001] The invention relates to the technical field of tunnel fire protection, in particular to a tunnel fire protection structure based on municipal water supply. Background technique [0002] Tunnels are engineering buildings buried in the ground, and are a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, and mine tunnels. With the development of my country's social economy, my country's highways, There are more and more tunnels used for passage in railways, urban roads, tourist routes, etc. [0003] At present, due to the closed space of the highway tunnel and the dense vehicles and people in the tunnel, once a disaster such as a fire occurs, because the existing tunnel firefighting requires firefighters to rush to the scene for fire fighting and rescue, it is very likely that the fire cannot be extinguished in time. It may cause heavy casualties and property losses. Therefore, it is...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a tunnel fire-fighting structure based on municipal water supply, mainly to solve the problem that the existing tunnel fire-fighting requires firefighters to rush to the scene for fire-fighting and rescue, and it is very easy for fires to be extinguished in time. Problems that may cause serious personal injury and property damage
