Abstract

The invention discloses an escape-rescue structure for a single-hole and double-direction traffic highway tunnel. The escape-rescue structure comprises a tunnel, wherein a roadbed is arranged in the tunnel and divides the internal space of the tunnel into an upper space and a lower space, and the upper space is used as a traffic passage; an evacuation and rescue passage located in the extending direction of the tunnel is arranged in the lower space and defined by partition walls, the traffic passage communicates with the evacuation and rescue passage through an emergency staircase, an entrance of the emergency staircase is arranged on a transverse side of the traffic passage, and an exit is arranged on a transverse side of the evacuation and rescue passage. With the adoption of the escape-rescue structure for the single-hole and double-direction traffic highway tunnel, the escape time of people can be shortened, the tunnel structure is more stable, and the total manufacturing cost is lower.

Description

technical field [0001] The invention relates to a tunnel escape and rescue structure, in particular to an escape and rescue structure for a single-hole two-way traffic highway tunnel. Background technique [0002] At present, with the rapid development of highway tunnels, single-hole and two-way traffic long tunnels in remote areas are gradually increasing. In order to meet operational safety requirements such as evacuation and rescue, single-hole and two-way traffic long tunnels generally adopt parallel pilot tunnels and cross passages next to the main tunnel to communicate with the main tunnel, and are used for evacuation and rescue in emergency situations. However, the construction of parallel pilot tunnels and cross passages is relatively difficult, so this design mode has high overall cost, long construction period, long time for personnel to escape, and poor safety. Contents of the invention [0003] In view of this, the object of the present invention is to provide...
