PARTIAL CAISSON DEVICE FOR REPAIRING CYLINDRICAL STRUCTURE IN WATER AND REPAIRING METHOD OF CYLINDRICAL STRUCTURE USING THEREOF

摘要

PURPOSE: A partial well caisson device for repairing an underwater cylinder structure and a repair method of the underwater cylinder structure are provided to reduce costs and time for installing a well caisson device. CONSTITUTION: A partial well caisson device(100) for repairing an underwater cylinder structure comprises a lower plate(11), a pair of side walls(13), an outer wall plate(14), an anchor(17a), an U-shaped fixing plate(19), and a watertight material(21). The lower plate is attached along a partial section of the cylinder structure. The side walls are vertically put on both ends of the lower plate and are integrally installed. A part of the anchor is inserted into the cylinder structure, and a U-shaped fixing plate fixes the anchor by being installed on the side wall. The watertight material attaches the lower plate and the side wall to the cylinder structure.
