Anti-sliding device used in tunnel

The utility model relates to the technical field of tunnel engineering construction, and discloses an anti-slip device used in a tunnel, which comprises an extension track and a retaining structure, the extension track is arranged between tracks, the length direction of the extension track is parallel to the length direction of the tracks, a plurality of sawtooth blocks are arranged on the extension track along the length direction of the extension track, and the sawtooth blocks are connected with the retaining structure. A limiting space is reserved between every two adjacent sawtooth blocks, each limiting space is provided with a first inclined face and a limiting face, and the first inclined faces and the limiting faces are located on the adjacent sawtooth blocks respectively. The anti-sliding device used in the tunnel solves the problems that an existing anti-sliding design is poor in timeliness, potential safety hazards exist, and damage to a tunnel structure is prone to being caused. 本实用新型涉及隧道工程施工技术领域，公
