Large caliber box culverts are often used on main drain lines, are difficult to maintain, and generally do not allow long-term water shut-down maintenance. Therefore, the damaged box culvert sections need to be quickly and emergently repaired to maintain the smoothness of the box culvert. Currently, some techniques for repairing culverts in use exist in the municipal construction field, and the method mainly uses plugging materials or plugging pieces to plug cracks. For smaller cracks or small-size culverts, the plugging method can achieve a better effect, but for culverts with large damaged areas or serious dislocation, particularly large-size box culverts, the plugging method is difficult to repair, or the sectional area loss of a flow passage after repair is large, so that a good repair effect is difficult to obtain, and only damaged parts can be cut off, and repair is performed by using a repair body. However, unlike small culverts, the repair of concrete-poured large-caliber box culverts has the difficulty that a large-size high-strength repair body is required to be used, and the machining and mounting difficulties of the repair body are greater, so that a repair structure needs to be reasonably designed, so that the repair structure can adapt to the practical situations of dislocation deformation, variable damage length and the like of the box culverts, and in addition, the convenience of transportation and construction operation is also considered.
