Referring to fig. 8, the disclosed embodiment also provides a method for repairing a deformation joint by using the culvert deformation joint water leakage drainage structure, which comprises the following steps:
s101, performing first expansion joint on the deformation joint 70 on the inner surface of the culvert wall body 81 to form a first preset groove 10 at the deformation joint 70;
s102, carrying out secondary seam expansion on the bottom end of the notch of the first preset groove 10 to form a second preset groove 50 at the bottom end of the notch of the first preset groove 10;
s103, arranging a drainage structure communicated with the deformation joint 70 between the notch of the first preset groove 10 and the deformation joint 70, wherein the leakage water on the culvert wall body 81 is discharged through the drainage structure;
s104, filling the waterproof structure 30 in the first preset groove 10 so that the waterproof structure 30 blocks the first preset groove 10;
and S105, filling the second preset groove 50 with a reinforcing structure 60 so that the reinforcing structure 60 blocks the second preset groove 50, wherein one surface of the reinforcing structure 60 is connected with the waterproof structure 30, and the other surface of the reinforcing structure 60 is flush with the inner surface of the culvert wall 81.
Further, before step S103, the method further includes:
referring to fig. 5, at least two grouting pipes 90 are arranged at intervals in the direction from the bottom end to the top end of the deformation joint 70, the grouting pipes 90 are approximately perpendicular to the deformation joint 70, and water-soluble polyurethane or a mixed solution containing water-soluble polyurethane is poured into the connection position 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 the structure is grouted, the portion of the grouting pipe 90 located at the deformation joint 70 is cut off, and the opening of the grouting pipe 90 is plugged with a plugging king or cement.
Furthermore, in the construction process, grouting treatment needs to be performed on the deformation joint, for example, water-soluble polyurethane is adopted for plugging, 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.
