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 on the first grouting holes, the void position and the internal
grout filling conditions of all the first grouting holes and all the second grouting holes are detected immediately through three-dimensional detection
radar, and grouting is stopped when the void position, all the first grouting holes and all the second grouting holes are filled with
grout; and the filling positions are detected and re-checked again through the detection
radar after grouting is stopped, and the positions which are not filled with
grout are drilled and grouted again. By the adoption of the bridge-head vehicle bump
road surface repairing method, the problem of the
settling velocity difference between the hard soil layer and the soft soil layer is solved.
