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.

Example Embodiment

[0013] see figure 1 and 2 , the embodiment of the present invention is provided with an annular life-saving pipe 2 and a high-pressure air supply device ( figure 1 and 2 not shown). 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 lifebuoy. An inlet and outlet valve ( figure 1 and 2 (not shown in the figure), 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 tube wall of the annular life-saving tube 2 is composed of 5 layers of rubber layers and at least 3 layers of carbon fiber layers. The composite material, the inner and outer surfaces of the hollow sealing tube wall are both rubber layers, and the carbon fiber layer is arranged between the two rubber layers. The annular life-saving pipe 2 is laid from the vicinity of the secondary lining 1 to the vicinity of the tunnel face 5 along the longitudinal direction of the tunnel. The inner diameter of the annular life-saving tube is 1.0m, and the outer diameter may be 1.2m. The high-pressure air supply device adopts the existing high-pressure air pump and other supporting devices ( figure 1 and 2 not shown). Reference numeral 4 denotes a collapse section area. Arrows indicate escape directions.
