Fill the reinforcement structure 60 in the second preset groove 50, so that the reinforcement structure 60 blocks the second preset groove 50, wherein, one side of the reinforcement structure 60 is connected to the waterproof structure 30, and the other side of the reinforcement structure 60 One side is flush with the inner surface of the culvert wall body 81 .

Further, before step S103, the method also includes:

Referring to Fig. 5, at least two grouting pipes 90 are arranged at intervals in the direction from the bottom to the top of the deformation joint 70, the grouting pipes 90 are approximately perpendicular to the deformation joint 70, and pass through the grouting pipes 90 to the culvert wall body 81. Water-soluble polyurethane or a mixed solution containing water-soluble polyurethane is poured into the joint with the roadbed 82 to seal the holes in the filler of the roadbed 82, thereby preventing the seepage water on the culvert wall body 81 from penetrating into the filler of the roadbed 82, thereby making the The leaking water is diverted to the diversion structure for discharge.

After the grouting structure, the part of the grouting pipe 90 located at the deformation joint 70 is cut off, and the opening of the grouting pipe 90 is blocked with plugging king or cement.

Furthermore, during the construction process, the deformation joints need to be grouted first, for example, water-soluble polyurethane is used for plugging. The construction is simple, the waterproof and anti-seepage performance is good, and the fixing speed is fast. During grouting, under the action of pressure, water-soluble polyurethane grout can permeate around the gap while pouring into the concrete gap, and continue to penetrate into the concrete gap, and finally form a network structure, becoming a low-density, water-containing elastic body, with Good ability to adapt to deformation, good water stop.
