TEMPORARY COFFERING STRUCTURE USING DEAD LOAD AND BUOYANCY AND CONSTRUCTION OR REPAIRING METHOD FOR IRRIGATION STRUCTURE USING THE SAME

摘要

The present invention relates to a cofferdam structures, by making the oebyeokche a double wall by so that the water receiving space formed between walls in the state that the water be filled in the water receiving space to receive the buoyancy, and the water in the water receiving space It established a structure such as a filled state, by forming to resist the water pressure which acts by its own weight, including the weight of water, drainage lock gate, a retaining wall or the bottom plate continuous with the hydraulic structures continue to receive the pressure of the sea water or fresh water, complement and there as reinforcements, and do not threaten the structural safety of hydraulic structures, the present invention relates to, without expensive disassembly and transport large equipment that is easy cofferdam construction and establishment and maintenance of hydraulic structures using the same method.
