s103, filling the preset groove 10 with the asphalt flax wadding layer 30 so that the preset groove 10 is plugged by the asphalt flax wadding layer 30, wherein the leakage water on the culvert wall body 81 is discharged through the drainage structure.

Further, after step S103, the method further includes:

a second waterproof layer 60 is arranged at the notch of the preset groove 10; the second waterproof layer 60 is disposed near the bottom end of the preset groove 10 and extends to the inner surface of the culvert wall 81 along the direction away from the notch of the preset groove 10, and the second waterproof layer 60 protrudes from the inner surface of the culvert wall 81.

Further, before step S102, the method further includes:

referring to fig. 4, at least two grouting pipes 90 are arranged at intervals in the direction from the bottom end to the top end of the settlement joint 70, the grouting pipes 90 are approximately perpendicular to the settlement joint 70, and water-soluble polyurethane or a mixed solution containing water-soluble polyurethane is poured into the joint of the culvert wall 81 and the roadbed 82 through the grouting pipes 90, so that holes in the roadbed 82 filler are sealed, thereby preventing water leakage on the culvert wall 81 from permeating into the roadbed 82 filler, and further guiding the water leakage to a flow guide structure for discharge.

After grouting the structure, the portion of the grout pipe 90 located at the settlement joint 70 is cut off, and the opening of the grout pipe 90 is plugged with a plugging king or cement.

Furthermore, in the construction process, grouting treatment needs to be performed on the settlement joint 70, for example, water-soluble polyurethane is adopted for plugging, so that the construction is simple, the waterproof and anti-seepage performance is good, and the telephone fixing speed is high. During grouting, under the action of pressure, the water-soluble polyurethane slurry can permeate around the gap while being poured into the concrete gap, and continuously permeate into the concrete gap to finally form a net structure, so that the water-containing elastomer with low density is formed, has good adaptive deformability and good water stopping property.
