Abstract

The invention belongs to the relevant field of tunnel construction rescue corollary equipment and discloses a passive tunnel construction life-saving system, wherein the system comprises a cabin arranged at the rear side of a tunnel face, a framework sledge arranged at the bottom of the cabin, multiple door structures arranged at the front and rear ends and left and right sides of the cabin, and multiple functional components which are used for air supply, oxygen supply, air purification, environment monitoring, communication, power supply, survival guarantee and the like and are arranged in the cabin. In addition, improved design is mainly performed on arrangement modes of the cabin and the door structures and the specific composition structures of key functional units. Compared with the existing equipment, the passive tunnel construction life-saving system has the advantages that the structural strength of the rescue capsule cabin is further ensured and improved, the escape efficiency and the rescue efficiency are obviously improved, and the passive tunnel construction life-saving system is applicable to various tunnel construction application occasions.

Description

technical field [0001] The invention belongs to the related field of tunnel construction rescue supporting equipment, and more specifically relates to a passive lifesaving system for tunnel construction. Background technique [0002] With the vigorous development of my country's traffic construction, more and more tunnel engineering safety problems appear in unfavorable strata such as weak surrounding rocks. In the construction of tunnels with weak surrounding rocks, due to unfavorable factors such as poor geological conditions, shallow surface covering soil, or tunnels passing through (building) structures, disasters such as deformation and landslides are extremely easy to occur during construction. In recent years, construction accidents in tunnels with weak surrounding rocks have occurred frequently, resulting in heavy losses of equipment and personnel, and great social impact. Subsequent investigations found that more than 70% of the landslides occurred at a certain dis...
