Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mounting device, in particular to a pipe roof mounting device for tunnel. BACKGROUND

[0002] The pipe roof is mainly used for the advance support structure in the soft and broken surrounding rock tunnel engineering with strict requirements for surrounding rock deformation and ground subsidence. The pipe roof constructed in advance provides support for the front surrounding rock and the rear surrounding rock, forms a beam structure, and forms a shell structure around the tunnel contour, which can effectively inhibit the loosening and collapse of the surrounding rock. The main functions of the pipe roof include beam arch effect, reinforcement effect, ring groove effect, and ensuring construction safety.

[0003] Before the existing pipe roof is installed, the arch frame in the arch and the guide steel pipe need to be installed on the inner wall of the tunnel first, then the formwork is formed, and then the inside of the formwork is poured with concrete to form an arch structure and preliminarily form the inner wall of the tunnel. Then, a set of parallel round holes are turned out in the inside of the arch frame by using a tunnel hole turning machine for the installation of the pipe roof. The existing pipe roof installation mainly uses a special conveyor to horizontally convey the pipe roof into the inside of the hole turning machine. Meanwhile, a plurality of round holes are arranged on the side of the pipe roof. Then, the one end of the pipe roof is grouted so that the grout fills the pipe roof and is discharged from the round holes on the side of the pipe roof and fills the hole turning machine, thereby achieving the connection and reinforcement of the arch frame. However, in the existing pipe roof conveying process, a straight track is arranged in the inside of the conveyor. Then, the track is used to horizontally convey the pipe roof. The horizontal conveying device can be horizontally extended, extended backward to place the pipe roof, and extended forward to approach the hole turning machine, so that the pipe roof can be horizontally inserted into the inside of the hole turning machine. During the extension process, the gravity center changes, which easily causes the pipe roof connected at the front end to shake due to gravity, thereby affecting the stability of the connection of the internal structure of the equipment. Meanwhile, the orientation of the pipe roof conveyed by the conveyor belt deviates from the original setting, thereby affecting the accuracy of the insertion. Therefore, we propose a pipe roof mounting device for tunnel. SUMMARY
