TECHNICAL FIELD
[0001] The utility model relates to a highway tunnel internal escape structure, especially a highway tunnel flood danger-avoiding device for coping with flood backflow. BACKGROUND
[0002] In some low-lying and rainy areas, due to the influence of extreme heavy rain during the operation of the tunnel, in addition to the tunnel entrance and exit being in a low-lying area, rainwater is prone to accumulate and backflow into the tunnel, which will seriously endanger the life and property safety of personnel in the tunnel. Therefore, in view of the phenomenon of tunnel flood backflow, in order to avoid personnel casualties and reduce economic losses as much as possible, it is very important to set up a tunnel escape device. When an accident occurs, the trapped personnel are difficult to escape quickly and effectively from the entrance and exit due to insufficient escape experience and the rapid arrival of the disaster. The existing technology sets a platform on a higher position inside the tunnel to overcome the above-mentioned problems. When a flood disaster occurs, personnel in the tunnel can hide on the platform, and then leave when the flood subsides. However, this structure is not applicable when the flood disaster water level is too high and exceeds the height of the platform. Moreover, personnel still have the risk of being trapped and cannot escape.
[0003] In recent years, escape channels have also been applied in tunnels. Most of them are spliced pipelines that extend horizontally through members to areas far away from the tunnel. They are aimed at landslides, tunnel accidents, and other disasters. The horizontally arranged escape channels only move away from the disaster area and cannot systematically solve the problem of being trapped in disasters. At the same time, how to evacuate trapped personnel more efficiently and quickly during escape is also an important factor in protecting personnel's life safety.
