Temporary coffering structure using dead load and buoyancy

摘要

The present invention is a temporary water barrier structure, the outer wall is made of a double wall so that the water receiving space is formed between the walls to receive buoyancy in the state that the water receiving space is not filled with water, the water in the water receiving space In the filled state, it is formed so as to resist the hydraulic pressure acting by its own weight including the weight of water, so that new structures such as drainage locks, hydraulic structures and continuous retaining walls or bottom plates that are continuously subjected to hydraulic pressure by sea water or fresh water are constructed and repaired. And in the reinforcement, and not to threaten the structural safety of the repair structure, and relates to a temporary clogging structure that is easy to dismantle and transport without expensive large equipment.
