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.

Embodiment Construction

[0013] see figure 1 and 2 , the embodiment of the present invention is provided with circular lifesaving pipe 2 and high-pressure gas supply device ( figure 1 and 2 not shown in). The pipe wall 3 of the annular lifesaving pipe 2 is a hollow sealed pipe wall, and the cross-sectional shape of the annular lifesaving pipe 2 is the shape of a swimming buoy. The pipe wall of the annular lifesaving pipe 2 is provided with an air inlet and outlet valve ( figure 1 and 2 not shown), the inlet and outlet valves are connected to the high-pressure gas outlet of the high-pressure gas supply device, and the wall material of the hollow sealing pipe wall of the annular lifesaving pipe 2 is formed by laminating 5 layers of rubber layers and at least 3 layers of carbon fiber layers Composite material, the inner and outer surfaces of the hollow sealed pipe wall are both rubber layers, and the carbon fiber layer is arranged between the two rubber layers. The annular lifesaving pipe 2 is laid...

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...
