description The invention relates to a concrete panel void repairing method. The purpose is to improve the efficiency of concrete anti-leakage panel void repairing and enhance the safety and reliability of engineering operation. According to the technical scheme, the method includes the steps that a, void region detection is performed, LTD ground penetrating radar is adopted for detecting a panel void region and determining the panel void region, and void depth information is collected; b, grouting hole positions are arranged inside the panel void region, the distance d1 between grouting holes is equal to 2 m-3 m, the row distance d2 is equal to 2 m-4 m, and quincunx-type arrangement or rectangular arrangement can be performed; c, drilling is performed according to the arrangement of the grouting hole positions; d, grouting starts to be performed upwards step by step from the lower portion of a panel in the grouting process; e, after two hours from grouting, cement mortar is adopted for plugging the grouting holes, the plugging height is larger than the height of the panel by about 3 mm-5 mm, and the surface of the panel is polished to be flat after standing for about 8 hours; f, in hot weather, water should be sprayed to the void repairing region for maintenance.
