CULVERT DEFORMATION JOINT LEAKAGE WATER DISCHARGE STRUCTURE AND METHOD FOR REPAIRING DEFORMATION JOINT

Disclosed are a culvert deformation joint leakage water discharge structure and a method for repairing a deformation joint. The culvert deformation joint leakage water discharge structure comprises a first preset groove (10) formed in an inner surface of a culvert wall body (81) and a second preset groove (50) formed at a groove opening of the first preset groove (10); an extension direction of the first preset groove (10) is the same as an extension direction of the deformation joint, two groove walls of the first preset groove (10) are arranged on two sides of the deformation joint respectively, and a groove bottom of the first preset groove (10) is communicated with the deformation joint; a groove width of the second preset groove (50) is larger than a groove width of the first preset groove (10), and a bottom end of the second preset groove is flush with a bottom end of the deformation joint; a drainage structure is arranged between the groove opening of the first preset groove (10) and the deformation joint, and the drainage structure is provided with a drainage channel (20) used for draining and discharging leakage water on the culvert wall body (81); and the first preset groove (10) and the second preset groove (50) are filled with a waterproof structure (30) and a reinforcing structure (60) respectively. The culvert deformation joint leakage water discharge structure can drain and discharge the leakage water, and has a good anti-seepage effect.
