Description

Technical Field

[0001] The utility model relates to the field of tunnel support, in particular to a tunnel construction support structure. Background Art

[0002] A tunnel is an engineering structure buried in the stratum and is a form of human utilization of underground space. During tunnel construction and excavation, a support structure is required to support the tunnel to prevent collapse. Most of the existing tunnel support structures are scattered brackets, which require multiple people to assemble and splice the scattered brackets simultaneously when in use, consuming a lot of labor and time and having low work efficiency. In addition, when the brackets need to be moved, they need to be disassembled again, which is not convenient for flexible movement.

[0003] After retrieval, it is found that a tunnel construction support device is disclosed in the Chinese patent with the authorization announcement number 202223600792.5, including: a base, a top plate, and side plates. The top plate fits against the top of the tunnel, and the support columns support the top of the tunnel. By sliding the fixing parts of the side plates in the grooves on both sides of the base, the support parts connected to the fixing parts are moved, so that the support parts fit against the side rock walls of the tunnel, realizing the support effect of the side plates on the side rock walls of the tunnel.

[0004] The above patent has the following deficiencies: The tunnel construction support device supports the top plate by setting support columns, which requires manual installation and splicing during support. At the same time, it is impossible to adjust the height of the support columns according to different heights, reducing the universality of the device's application. At the same time, when the whole device needs to be moved, it needs to be disassembled and cannot be moved as a whole, with poor flexibility in use. Summary of the Utility Model
