[0002] The inverted arch is a reverse arch structure set at the bottom of the tunnel to improve the stress conditions of the upper supporting structure. It is one of the main components of the tunnel structure. The inverted arch can effectively transfer the stratum pressure above the tunnel to the underground through the tunnel side wall structure or the load on the road surface, and can also effectively resist the reaction force from the stratum below the tunnel. The inverted arch and the secondary lining constitute the whole tunnel and increase the stability of the tunnel structure. The operator uses the inverted arch trestle to construct the inverted arch.

[0003] When the existing inverted arch trestle is in use, cars need to go up and down through the side slopes on both sides. However, due to improper structural settings and a lot of impurities on the side slopes after long-term use, the cars are prone to slipping, affecting the processing progress of the project and even causing production accidents.
