[0074] Whether a gap needs to be reserved between the top end of the first preset groove 10 LUS06299 and the top end of the deformation joint 70 and how high the gap needs to be reserved may be arbitrarily set according to a water leakage situation of the culvert wall body 81. For example, when the moderate water leakage and the serious water leakage occur in the culvert wall body 81, as shown in FIG. 1, FIG. 2, FIG. 4 and FIG. 5, the top end of the first preset groove is located in the 3/4 of the height of the deformation joint 70, that is, the top end of the first preset groove 10 is located in the 3/4 of the height of the deformation joint 70. When the slight water leakage occurs in the culvert wall body 81, as shown in FIG 6 and FIG 7, the top end of the first preset groove 10 is flush with the top end of the deformation joint 70.

[0075] In addition, if the drainage pipe 201 is clamped in the deformation joint 70, the top end of the drainage pipe 201 may extend out of the first preset groove 10 to be flush with the top end of the deformation joint 70.

[0076] In this embodiment, the first preset groove 10 and the second preset groove 50 are both symmetrically arranged along a center line of the deformation joint 70. In specific implementation, the first preset groove 10, the drainage pipe 201 and the second preset groove 50 are all symmetrically arranged along the deformation joint 70, which is convenient for construction, stable in structure, beautiful in appearance and good in waterproof performance.

[0077] Second Embodiment

[0078] With reference to FIG. 8, the embodiment of the present disclosure further provides a method for repairing a deformation joint by using the culvert deformation joint leakage water discharge structure above. The method comprises the following steps of:

[0079] S101: carrying out first joint expansion on the deformation joint 70 in the inner surface of the culvert wall body 81 to form the first preset groove 10 at the deformation joint 70;

[0080] S102: carrying out second joint expansion on a bottom end of the groove opening of the first preset groove 10 to form the second preset groove 50 at the bottom end of the groove opening of the first preset groove 10;

[0081] S103: arranging the drainage structure communicated with the deformation joint 70 between the groove opening 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;

[0082] S104: filling the waterproof structure 30 in the first preset groove 10, so that the waterproof structure 30 seals the first preset groove 10; and 13

BL-5817

[0083] S105: filling the reinforcing structure 60 in the second preset groove 50, so that the LU506299 reinforcing structure 60 seals the second preset groove 50, wherein one face of the reinforcing structure 60 is connected with the waterproof structure 30, and the other face of the reinforcing structure 60 is flush with the inner surface of the culvert wall body 81.

[0084] Further, before the step S103, the method further comprises the following steps of:

[0085] as shown in FIG 5, arranging at least two grouting pipes 90 at intervals in a direction from the bottom end to the top end of the deformation joint 70, wherein the grouting pipe 90 is approximately perpendicular to the deformation joint 70; and pouring water-soluble polyurethane or a mixed liquid containing the water-soluble polyurethane into a connecting part between the culvert wall body 81 and a subgrade 82 through the grouting pipe 90, so as to seal a hole in a filler of the subgrade 82, thus avoiding the leakage water on the culvert wall body 81 from seeping into the filler of the subgrade 82, and then guiding the leakage water into the drainage structure to be discharged.

[0086] After grouting the structure, a part of the grouting pipe 90 located at the deformation joint 70 is cut off, and an opening of the grouting pipe 90 is sealed with a leak-stopping agent or cement.

[0087] Further, in a construction process, the deformation joint needs to be grouted first, such as plugging with the water-soluble polyurethane, which is simple in construction, good in waterproof and anti-seepage performances, and fast in solidification speed. During grouting, under a pressure, the water-soluble polyurethane slurry may permeate around the joint when being grouted into the concrete joint, and then continuously permeate into the concrete joint to finally form a net structure, which is a low-density water-containing elastic body, with a good adaptability to deformation and a good water stop performance.

[0088] Specific technical features are the same as those of the above embodiment, and the same or similar technical effects can be achieved, which will not be repeated herein. The details may refer to the description in the above embodiment.

[0089] It should be noted that relational terms, such as “first” and “second”, and the like, used herein are only intended to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that any such actual relationship or sequence exists between these entities or operations. Furthermore, the terms "comprise", "include", or any other variation thereof, are intended to cover a non-exclusive inclusion, so that a process, a method, an article, or equipment that comprises a list of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article, or equipment. In a case without 14

BL-5817 further limitations, an element defined by the phrase "comprising one..." does not preclude LUS06299 the presence of additional identical elements in the process, method, article, or equipment that includes the element.
