The tunnel reinforcing device with the inflatable folding structure comprises a first supporting culvert pipe and a second supporting culvert pipe, compensation structures are arranged on the two sides of the attached position of the first supporting culvert pipe and the second supporting culvert pipe, and containing grooves are formed in the top ends of the first supporting culvert pipe and the second supporting culvert pipe; according to the tunnel reinforcing device with the inflatable folding structure, a soil body at the top end of a tunnel can be supported, the supporting structure is arranged in the containing groove, materials of the tunnel can be saved, the side wall of the tunnel is supported through the folded connecting air bag, the position of the supporting plate on the connecting air bag is convenient to adjust, and the tunnel reinforcing device is convenient to use. Therefore, the impact on the supporting culvert pipe due to soil collapse is reduced; a large gap can be prevented from being gen
