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.
