Claims

[Claims for Utility Model Registration] 1. A box 1 consisting of a main body 2 with a U-shaped cross section and a bottom plate 3 having an end shape that approximately matches the surface shape of an underwater structure 12. A tubular elastic body 4 formed into a tubular shape made of a deformable material capable of withstanding a predetermined pressure is fixed to both ends 2a of the main body 2 and an end of the bottom plate 3, and is brought into contact with the surface of the underwater structure 12. A water stop operation characterized in that a compressed air supply pipe 5 is connected to supply compressed air into the tubular elastic body 4 and a pump 9 is installed to discharge water inside the box 1 to the outside of the box 1. Box. 2. The water-stop work box according to claim 1, wherein round bars 10 are fixed to both ends 2a of the main body 2 and to the ends of the bottom plate 3 while being positioned inside the tubular elastic body 4. 3. The water-stop work box according to claim 1, wherein a round steel 10 is fixed to both ends 2a of the main body 2 and an end of the bottom plate 3, and a tubular elastic body 4 is fixed to the outside of the round steel 10. . 4. The water stop according to any one of claims 1 to 3, wherein a pressure reducing valve 7 is provided in the middle of the compressed air supply pipe 5 to adjust the compressed air supplied into the tubular elastic body 4 to a predetermined pressure. Work box. 5. The water-stop work box according to claim 1, wherein a pressure gauge 8 for measuring the pressure inside the tubular elastic body 4 is provided in the middle of the compressed air supply pipe 5. 6.
