Bridge-head vehicle bump road surface repairing method for solving problem of settling velocity difference between hard soil layer and soft soil layer

The invention relates to a bridge-head vehicle bump road surface repairing method for solving the problem of the settling velocity difference between a hard soil layer and a soft soil layer. The bridge-head vehicle bump road surface repairing method comprises the steps that a void position in an access board of a damaged bridge is detected through detection radar, the positions of first grouting holes are marked on the surface of the access board, drilling is conducted on the positions of the first grouting holes, the first grouting holes are deep enough to reach the hard soil layer, the first grouting holes are arranged in an array mode, the center-to-center distance between every two adjacent first grouting holes is 10-20 cm, and the void position is made to be located within the array range; all second grouting holes penetrate through the soft soil layer and intersect with the first grouting holes, and exhaust one-way valves are arranged at the two ends of each second grouting hole; grouting is conducted o
