Escape device for tunnel construction

Abstract

The invention discloses an escape device for tunnel construction. The escape device comprises a first supporting plate, wherein an escape capsule is fixedly connected to the upper part of the first supporting plate; and a supporting column is fixedly connected to the upper part of the first supporting plate. Through the arrangement of a first compression-resistant device and a second compression-resistant device, when stones are accumulated on a rectangular plate and the rectangular plate is subjected to pressure, a first spring is compressed by two compression-resistant plates to exert a compression-resistant effect on the supporting column; and when a relatively large stone falls into a rectangular block, a rotating shaft pushes a connecting shaft to move, the connecting shaft pushes a first sliding block to move, the first spring is compressed by the first sliding block to exert the compression-resistant effect, and meanwhile, a connecting block further exerts the compression-resistant effect through a compression elastic plate; and through the arrangement of a sweeping device, the stones accumulated on the rectangular block are swept down, so that the pressure of the stones on the rectangular plate is relieved. The escape device solves the problem of tunnel collapse caused by the fact that an escape pipeline and the escape capsule are hit by the stones, and the safety of tunnel construction personnel is guaranteed.

Description

technical field [0001] The invention relates to the technical field of tunnel escape, in particular to an escape device used in tunnel construction. Background technique [0002] When building a tunnel, due to changes in the water in the rock and soil, the water flows along the weak surface of the rock mass, destroying the rock mass tissue, causing the rock mass to become unstable and causing landslide accidents, or rainwater seeps into the fault zone and cracks to form a sliding surface, and the rocks slide against each other. Squeeze and deformation by internal force can also easily cause landslides. Due to changes in geological structures in local areas, fault fracture zones, weak interlayers and other engineering geological conditions during tunnel construction, if the construction preventive measures are not appropriate and not in time, it is easy to cause tunnel landslide accidents. The more common safety accident is the collapse of the tunnel. Generally, escape pipes ...

[0002] When building a tunnel, due to changes in the water in the rock and soil, the water flows along the weak surface of the rock mass, destroying the rock mass tissue, causing the rock mass to become unstable and causing landslide accidents, or rainwater seeps into the fault zone and cracks to form a sliding surface, and the rocks slide against each other. Squeeze and deformation by internal force can also easily cause landslides. Due to changes in geological structures in local areas, fault fracture zones, weak interlayers and other engineering geological conditions during tunnel construction, if the construction preventive measures are not appropriate and not in time, it is easy to cause tunnel landslide accidents. The more common safety accident is the collapse of the tunnel. Generally, escape pipes and escape cabins are built in the tunnel. When the tunnel collapses, workers enter the escape pipe to escape, or enter the escape cabin to wait for rescue. Not strong, because more and more stones are piled up on the top of the escape cabin, it is easy to crush the escape cabin, which seriously affects the safety of workers. Therefore, we propose an escape device for tunnel construction
