When the tunnel boring machine performs excavation on a large slope, the composite TBM1 is used for tunneling and excavation. In order to prevent the large slope from slipping and causing damage to the tunnel boring machine, the large slope is supported and protected by an anti-slip fixing device installed on the base 2. To prevent slipping and collapse on large slopes, the anti-skid fixing device mainly consists of a protective support structure, a guide sliding structure and auxiliary protective components.

Through the cooperation between the various components of the guide sliding structure, the entire device can be moved conveniently, and the contact with the large slope can be facilitated, and the operation is simple.
