description The utility model belongs to the technical field of tunnel construction, and particularly relates to a tunnel reinforcing structure which comprises a supporting plate. A motor is fixedly connected to the end part of the supporting plate; the output end of the motor is fixedly connected with a right-hand and left-hand thread lead screw. The sliding block is connected with the right-hand and left-hand thread lead screw through a lead screw nut pair. The sliding blocks are symmetrically arranged; a guide rod is hinged to the top of the sliding block. When the tunnel is reinforced, the guide rod pushes the ejector block to move towards the top, the ejector rod is driven to move upwards in the moving process of the ejector block, the ejector rod pushes the reinforcing plate to abut against the inner side wall of the tunnel, supporting and reinforcing are conducted, and the reinforcing effect of the tunnel is improved; and a sliding block drives a guide rod to rotate towards the end part, so that a top block moves
