However, simply injecting concrete cannot meet the requirement of firm concrete. Therefore, it is necessary to tie steel bars arranged in a net shape on the tunnel inner wall before injecting concrete. Tunnel steel bar tying is an essential construction process. In the process of tunnel steel bar tying, the steel bars are divided into tunnel longitudinal steel bars arranged along the tunnel longitudinal direction and circumferential transverse bars along the transverse direction of the tunnel inner side wall.
