Abstract

PURPOSE: To sink and construct the structure economically and safely by sending compressed air into the inside of the box-type concrete foundation structure for regulating the air pressure inside so that it always equilibrates with the water pressure to a temporary lid, accompanying upon the sedimentation of the structure.
CONSTITUTION: When the box-type concrete foundation structure 7 reaches the water bottom 19, the air supply valve 15 is closed and the valve 3 of the air blow pipe 4 and the valve 12 of the water charging pipe 1 are opened to gradually expel the compressed air into the water through the air blow pipe 4 by charging water into the structure 7, and then the temporary lid 6 is removed by a diver. Thus, because the compressed air can be expelled into water through the air blow pipe 4 provided at the same level as the lower side of the temporary lid 6 in line with the lower side 4' of the air outelt, the compressed air in the structure can be discharged into water while keeping it pressure constant.
