[0010] As a preferred technical solution of the utility model, the first pipeline, the second pipeline and the third pipeline are all provided with a delivery inner tube, the outer wall of the delivery inner tube is welded with a reinforcing bracket, and the delivery inner tube is connected to the delivery hose.

[0011] Compared with the prior art, the utility model provides a gas bridge pipe structure, which has the following beneficial effects:

[0012] 1. A gas bridge pipe structure is a gas bridge pipe for crossing a river. It adopts a scheme of being laid along the bridge. The first pipe is fixedly installed on one side or the bottom surface of the bridge through a first mounting seat, and the second pipe is set to an L-shaped structure, which can change the direction of the gas bridge pipe. The third pipe extends to the soil on the slopes on both sides of the bridge, and is installed on the bridge together with the first mounting seat through the second mounting seat and the connecting steel plate. At this time, the connection ends of the first pipe and the second pipe (horizontal end) will not be staggered and deformed due to the uneven settlement of the slopes on both sides of the bridge and the main body of the bridge. At the same time, in conjunction with the corrugated compensation pipe, the pressure on the connection end of the third pipe (vertical end) can also be effectively reduced, and the overall safety and stability are improved.

[0013] 2. This gas bridge pipe structure is provided with an inner transmission pipe, and a gas detection instrument (such as an alarm) can be connected to the joint to detect whether the inner transmission pipe is ruptured. Even if it is ruptured, there will still be no gas leakage accident, which can play a role in safety protection and warning. BRIEF DESCRIPTION OF THE DRAWINGS
