Double-layer firefighting escape tunnel

Abstract

The invention relates to the field of tunnel technical control, in particular to a double-layer firefighting escape tunnel which comprises a concrete shell with a circular section, an anti-seepage protective layer, an upper-layer travel lane, a lower-layer travel lane, a lower-layer smoke exhaust channel, ventilating and lighting systems, traffic lamps, vertical bearing walls, an upper-layer smokedischarge channel, anti-collision protective pads, fireproof heat-insulation walls, escape channels, a gravel and coarse sand layer, firefighting water spray devices, lane structure bottom plates, fireproof sensing and alarm systems, an upper-layer escape channel, a lower-layer escape channel, through holes, smoke exhaust machines, waterproof cloth and a special cabin for sponge cities. The double-layer firefighting escape tunnel has the advantages that the continuous anti-seepage protective layer is arranged on the outer side of the concrete shell with the circular section, the upper-layer travel lane is arranged on an upper layer of the double-layer firefighting escape tunnel, the lower-layer travel lane is arranged on a lower layer of the double-layer firefighting escape tunnel, accordingly, the problems that personnel in tunnels cannot escape from danger at present due to accidents such as collapse, fire hazards or blocked tunnel exits and the like can be effectively solved by theaid of the double-layer firefighting escape tunnel, and personnel in the double-layer firefighting escape tunnel can effectively save themselves when danger and accidents occur.

Description

technical field [0001] The invention relates to a tunnel, which belongs to the technical control field of tunnels, in particular to a double-layer fire escape tunnel. Background technique [0002] Tunnels and underground engineering are playing an increasingly important role in today's three major challenges of "population growth, resource shortage, and environmental degradation" due to their outstanding advantages of not occupying ground land resources. Therefore, their applications are becoming more and more important. The more extensive it is, the so-called "play in the ground". In the past ten years, my country's tunnel and underground engineering construction has developed rapidly, not only in the increase in the number and length of tunnels, but also in the rapid development of technology, and continuous breakthroughs in the application of various construction methods . Most of the subway tunnels in China adopt the shallow-buried underground excavation method, includi...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the above existing technical problems, the present invention provides a double-layer fire escape tunnel with simple structure, good mechanical performance, strong bearing capacity and stable quality, which can effectively solve the current accidents caused by collapse, fire or blocked tunnel exit. It leads to the problem that people in the tunnel cannot get out of danger, and can effectively realize the self-rescue of people in the tunnel when a dangerous accident comes.
