PROBLEM TO BE SOLVED: To reinforce an underwater structure at low cost and within a short construction term even in the great depth of water.SOLUTION: In a first step, a wall body 10 for a mold frame is installed around an underwater structure. In a second step, a gap between the wall body 10 for a mold frame installed in the first step and the underwater structure is filled with filling. In a third step, a temporary coffering wall body 40 is installed around the underwater structure higher than the wall body 10 for a mold frame. In a fourth step, water between the temporary coffering wall body 40 installed in the third step and the underwater structure is drained, thereby forming a space for performing underwater structure reinforcing work therein. |
