REINFORCING METHOD OF BANK

PROBLEM TO BE SOLVED: To surely and quickly reinforce a bank by filling an appropriate container with concrete, and arranging the container at the prescribed parts of the bank as concrete remains in non-hardened state. SOLUTION: An opening part is formed in the upper part of a cloth-made or synthetic resin-made container 2 to provide a cover part on the opening part, and a suspension part is provided on the container 2. During execution, after a crane truck 9 and a truck mixer 10 are arranged in the neighborhood of the breaking prediction place of a bank 1, the container is filled with ready- mixed concrete appropriately blending aggregate at the place, the opening part is blocked by a string, the container is hung up by the crane truck 9, and successively disposed in recess parts 4 formed at the prescribed parts of the face of the side of a river 11. Since concrete is not hardened yet, the disposed container 2 deforms along the shape of the recess part 4 to bury the recess part 4 well. Thereby the bank 1 can be reinforced surely and quickly.
