Abstract

The invention belongs to the relevant field of tunnel construction rescue support equipment, and discloses a tunnel construction life-saving system. The system comprises a cabin arranged behind a tunnel face, multiple door structures arranged on the front and rear end faces and the left and right side faces of the cabin, and a plurality of functional units integrated in the cabin and used for air and oxygen supplying, air purifying, environment monitoring, communication, power supplying, survival guarantee and the like. In addition, the arrangement modes of the cabin and the door structures and specific composition structures of the key functional units are improved in an emphasized mode. By means of the system, compared with existing equipment, escaping and rescue efficiency can be obviously improved while the structural strength of the life-saving cabin is further ensured and improved, cabin door positions can be accurately located, and therefore the system is suitable for various tunnel construction application occasions.

Description

technical field [0001] The invention belongs to the field of tunnel construction rescue supporting equipment, and more specifically relates to a tunnel construction lifesaving system. 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 distance behind the tun...
