TECHNICAL FIELD

[0001] The present application relates to the field of survival devices, in particular to a tunnel construction collapse survival device. BACKGROUND

[0002] In the tunnel construction process, since the tunnel is a closed space, once the tunnel collapses locally, it is easy to block the tunnel, causing the construction personnel to be trapped in the tunnel. In the prior art, the trapped construction personnel is supplied with survival supplies through pipeline transportation, for example, the patent with publication number CN102996175A discloses a mine disaster survival system, which mainly comprises a ground general control room, a conveying pipeline and a distribution box, characterized in that: the ground general control room is provided with long-term prepared effective inhalable oxygen, drinking water and nutrient solution, the conveying pipeline is kept connected and reliable for conveying, the general control room is designed with a communication device, an alarm device, a control valve and a detection table, when the mine or tunnel encounters an emergency such as collapse, the internal workers can alarm through the alarm device in the nearby distribution box, and report the internal situation to the external general control room through the communication device, the external general control room timely opens the valve to transport oxygen, drinking water, nutrient solution and other materials to the pipeline according to the emergency situation inside, the present application is simple to operate, fully utilizes the life-sustaining materials, solves the problem of prolonging human life when underground workers encounter special events, and provides sufficient time for external rescue personnel to rescue, which is a timely, convenient and effective mine disaster rescue system.

[0003] However, through the pipeline transportation mode, the pipeline is easy to be broken by falling rocks during the collapse, causing the oxygen, drinking water, nutrient solution and other materials to leak halfway, so that they cannot be delivered to the trapped personnel, and improvement is needed. SUMMARY

[0004] The present application aims to provide a tunnel construction collapse survival device to solve the above technical problems.

[0005] To solve the above technical problems, the present application adopts the following technical solutions:

[0006] A tunnel construction collapse survival device, comprising: a fixing mechanism; a long hose, the left end of which is connected with the fixing mechanism; an escape pipeline, in which the long hose is located; a long strip-shaped air bag, which is sleeved outside the long hose, and the left and right ends of the air bag are fixedly connected with the long hose.

[0007] Preferably, it further comprises an inflation tube, which is fixedly arranged at the left end of the air bag; and a sealing cover, which is threadedly connected with the inflation tube.

[0008] Preferably, the fixing mechanism comprises a connecting block fixedly connected with the left end of the long hose, and a plug rod with the top end connected with the bottom of the connecting block.

[0009] Preferably, the fixing mechanism further comprises a water pump fixedly connected with the left side of the connecting block, wherein the water inlet of the water pump is connected with the first water pipe, and the water outlet of the water pump is connected with one end of the second water pipe; and a connecting pipe fixedly arranged at the left end of the long hose, wherein the other end of the second water pipe is connected with the connecting pipe.

[0010] Preferably, the support mechanism comprises arc-shaped support plates fixedly arranged on the upper and lower sides of the inner wall of the long hose, a driving rod with one end connected with the arc-shaped support plates through a first hinge, a driving shaft with the other end of the driving rod connected with the left end of the driving shaft through a second hinge, a guide pipe in which the driving shaft is located, a piston slidably connected with the inner wall of the guide pipe and fixedly connected with the driving shaft, and a gas guide pipe with one end fixedly connected with the right end of the guide pipe and in communication with the guide pipe, and the other end fixedly connected with the long hose and in communication with the air bag.

[0011] Preferably, the support mechanism further comprises a spring with one end fixedly connected with the piston, and a sealing cover with the other end of the spring fixedly connected with the sealing cover and the right end of the guide pipe.

[0012] Preferably, the support mechanism further comprises a guide ring sleeved on the driving shaft and fixedly connected with the inner wall of the guide pipe.

[0013] Preferably, the bottom of the plug rod is fixedly provided with a conical plug.

[0014] The present application has the following advantages:

[0015] 1. The escape pipeline is arranged in the tunnel, the right end of the escape pipeline is arranged at the construction position in the tunnel, and the plug rod is inserted into the soil outside the tunnel. When the tunnel collapses and the construction personnel are trapped in the tunnel, the rescue personnel can use the water pump outside the tunnel to supply drinking water, milk and other liquids to the trapped personnel through the long hose, so that the trapped personnel can survive for a longer time to wait for the rescue personnel.

[0016] 2. In the event of a tunnel collapse, the escape tunnel can prevent rubble and soil from pressing down on the long flexible hose, keeping it unobstructed. If the escape tunnel is broken by rubble during a collapse, the collapsed soil and rubble will enter the escape tunnel and press down on the airbag. The airbag can act as a buffer, preventing the long flexible hose from being flattened. Furthermore, when the airbag is compressed by soil, the gas inside the airbag is forced into the guide tube through the air duct to drive the piston to move. This causes the drive rod to extend and press against the support arc-shaped support plate, which in turn expands the long flexible hose, further preventing it from being flattened and ensuring that supplies such as water and milk can be transported through the long flexible hose.
