[0002] When constructing large-section tunnels under adverse geological conditions, it is usually necessary not only to implement large pipe-roof support in the tunnel direction, but also to implement large pipe-roof support on both sides of the tunnel to improve the overall safety of the tunnel support.

[0003] Due to the limitation of the horizontal space of the tunnel, when constructing a large pipe shed on both sides of the tunnel, it is often necessary to push the pipe shed forward in sections, and connect the adjacent sections of the pipe shed with threaded connection sections.

[0004] However, during actual construction, in order to accurately control the insertion angle of the pipe roof, it is often necessary to specially construct a guide wall, which will affect the construction efficiency of the pipe roof and increase the lining support construction period.
