Description

Technical Field

[0002] A shed tunnel is a tunnel formed by constructing a simply supported roof frame after excavating a cutting and then backfilling it. It belongs to the category of open tunnels. The conditions for using a shed tunnel are roughly similar to those for an open tunnel. Its structural integrity is worse than that of an open tunnel, but because the roof and inner and outer walls are simply supported, the requirements for the foundation are relatively low. There are many types of shed tunnels depending on the terrain and geological conditions, but their basic structure includes inner walls, outer supporting structures and top plate supporting structures.

[0003] However, the following problems still exist: the shed hole protection device in the equipment is inconvenient to install between the brackets, and it is impossible to install it quickly according to the length required for support, which makes the installation time-consuming and labor-intensive, affecting the installation efficiency.
