摘要
[PROBLEMS] To perform a repair work to suppress a collapse accident in a coastal area at a low cost within a short period of time and to suppress a collapse accident caused by the occurrence of a cavity after the repair work, adjacent to a caisson dam structure. Provide repair methods for coastal areas. A buffer joint material 40 having a wave force damping action and a sediment outflow restraining action is used, and the buffer joint material 40 is installed in a joint part G formed between the side surfaces of adjacent caisson 10 and closed. In this state, the upper layer of the coastal area located on the land side of the joint portion is partially excavated to form the cut groove 23, and after repairing the sandproof sheet 31 exposed in the cut groove 23, the cut groove 23 is refilled. The buffer joint material 40 positioned in the joint portion G is left without being removed. [Selection] Figure 3
