Safe passage device used in tunneling construction collapse

Abstract

The invention provides a safe passage device used in a tunneling construction collapse, relating to a safe passage device used in a tunneling construction collapse which is convenient to escape. The device has the advantages of small occupied space, low cost, easiness in self construction and extremely low tunneling construction interferences. The device is provided with annular lifesaving tubes with hollow sealed tube walls and a high-pressure air supply device. When the device is used, the annular lifesaving tubes are paved at the left or right side in the tunnel directly until the annular lifesaving tubes are paved at positions close to a working face from positions near a secondary lining in the longitudinal direction of the tunnel. When the collapse happens in the tunneling construction, the high-pressure air supply device injects high-pressure gases into the annular lifesaving tubes, so that the annular lifesaving tubes expand into emergency rescue safe passages like swimming lifebelts. Workers can use the expanded annular lifesaving tubes to pass through a collapsed zone for escape, thus reaching the purpose of rescuing trapped persons.

Description

technical field [0001] The invention relates to tunnel construction equipment, in particular to a tunnel construction landslide safe channel device for easy escape. Background technique [0002] Tunnel construction collapse refers to the collapse of tunnel surrounding rock or tunnel face caused by sudden and uncontrollable stress release during construction, which is one of the common disasters in tunnel construction. The occurrence of tunnel construction landslides not only leads to significant economic losses, adverse social impact, and even endangers the safety of personnel at the construction site. A large number of studies have shown that the existence of a large number of uncertain factors in tunnel engineering is the root cause of frequent construction landslide accidents, especially the high incidence of landslide accidents in tunnels constructed by the drill and blast method, which is a common construction method for tunnel construction. Construction landslides ser...

Problems solved by technology

Due to the unsatisfactory effect of the current tunnel construction landslide rescue measures and the high cost, the tunnel construction landslide rescue is still a worldwide problem

At present, there are also related technical reports. They have their own characteristics, but they generally have the disadvantages of large space occupation, high cost, complicated construction, and great interference to tunnel construction.
