SOLUTION: A casing 3 is put in the water, and is put in a state of putting water W inside. A close contact body 4 in front of the casing 3 is pressed to and brought into close contact with a rubber dam 1. The damage part R in the water of the rubber dam 1 is surrounded by a front opening part P1, and an upper surface opening part P2 is positioned on the water. The water W inside of the casing 3 is drained outside by a drainage pump 8 via a drain pipe 9 arranged inside the casing 3 from this upper surface opening part P2.
