Rapid repairing method for damage to bridge expansion joint notch
The invention discloses a rapid repairing method for damage to a bridge expansion joint notch. The rapid repairing method includes the following steps that S1, concrete of the expansion joint notch is chiseled out for trimming, dust is cleaned away, and water is removed; S2, the expansion joint notch is coated with a primer; S3, polyurethane elastic concrete is prepared, and aggregate is doped while the polyurethane elastic concrete is guided into the expansion joint notch until the expansion joint notch is filled; S4, the polyurethane elastic concrete is subjected to surface finishing, so that the surface of the polyurethane elastic concrete is flat.
