Tunnel Roof Support Installation Skills:
1. The laying direction of tunnel roof supports and wire troughs should be short and quick, and should be laid along walls, columns or beams as much as possible.
2. According to the laying direction of the tunnel roof support bridge and the wire trough, propose to the civil engineering and
structural majors the position and load of the pre-embedded steel plates
required for the installation of wall holes, floor holes and hangers.
At the same time, the installation of tunnel roof supports should also be coordinated with the majors of craftsmanship, plumbing and power.
3. The wiring of the concealed metal trunking in the ground should be closely coordinated with the civil engineering major in the design, so as to reasonably determine the line path and equipment selection for the installation of the tunnel roof support according to different structural types and building layouts.
