[0002] After the tunnel is excavated, it is necessary to cover the inner wall of the tunnel entrance with lining to form a solid tunnel body to increase the firmness and durability of the tunnel. The lining is generally composed of steel bars and concrete. After the lining construction is completed, due to the influence of geological conditions or improper construction, there will be construction problems such as lining voids, cracks, exposed steel bars or water seepage in local areas. The traditional lining repair method is generally to knock down the concrete at the problematic area, set up the formwork and re-pour the concrete at the problem point. Since the lining needs to be supported by the formwork at the bottom of the lining during repair, and the tunnel entrance is relatively high, the erection of the local formwork requires the production of special-shaped formworks, which consumes a lot of manpower and material resources.
