Escape device for tunnel fire disaster

Abstract

The invention discloses an escape device for a tunnel fire disaster. The escape device comprises a through hole penetrating through the top of a tunnel, folding ladder and a fire alarm which are fixedat the through hole, wherein a skylight and an emergency escape platform are arranged above the through hole, multiple layers of steps are arranged on the folding ladder, an anti-skid pad is arrangedon the steps, the folding ladder can be folded in a space defined from the top of the tunnel to the emergency escape platform during storage, when a fire disaster occurs in the tunnel, trapped persons in the tunnel can climb out of the tunnel through the folding ladder, the folding ladder is lowered to a fixed position on the ground, an included angle between the folding ladder and the ground is60 degrees preferably, the stability of the folding ladder after lowering to the ground is increased, the difficulty during escape climbing is reduced, and when people are fully evacuated, the foldingladder rises to the top, the space of the tunnel is not occupied, and normal use of the tunnel is not impeded.

Description

Technical field [0001] The invention belongs to the technical field of escape devices, and particularly relates to an escape device used for tunnel fire disasters. Background technique [0002] In recent years, the construction of urban subways in my country has developed rapidly, and the scale of subway tunnels has become larger and larger. At the same time, the rapid development of infrastructure such as high-speed railways and highways has caused a rapid increase in the number of tunnels. Due to the narrow and long space in the tunnel, once a fire occurs, especially in urban subway tunnels, emergency evacuation is extremely difficult due to the high density of people, which often results in large casualties. The current domestic tunnel escape methods are mainly the planning of evacuation routes and the addition of communication channels between multiple tunnels. In order to solve the shortcomings of existing escape methods and technologies, the present invention provides a new...
