METHOD FOR STABILIZING FLOATING STRUCTURE

摘要

PURPOSE: A floating structure stabilizing method is provided to stabilize the structure by moving down a supporting unit after digging without removing the structure, and to reduce loss by constructing after removing the structure floated on groundwater. CONSTITUTION: A lower part of a structure(10) floated on groundwater is supported with a sandbag(21) or an oil jack, and the structure is stabilized with digging under groundwater. The circumference around the structure is detected, and the structure is moved down through the bottom of the structure or by digging the rear part of the structure. Earth and sand(30) are eliminated from the lower part of the structure, and the structure is supported with the sandbag or the oil jack. Earth and sand are dug out under the structure, and the sandbag is washed away with sprinkling high-pressure water. The structure is moved down slowly with excavating the sandbag or with descending the oil jack. An earth wall(31) is installed with perforating the wall and grouting or inserting a steel member to prevent inflow of earth and sand. The structure is supported with the supporting unit, and the ground below the structure is dug and removed. The floating structure is stabilized with moving up and down the supporting unit.
