Abstract

PURPOSE: To display a buffer effect to the whole encasements when the encasements fall by a method wherein buffer materials are mounted into the encasements so as not to mutually interfere when the encasements expand and round, and buffer materials are fitted on the surfaces of bottoms in the encasements.
CONSTITUTION: Buffer materials 2 such as foamed polyethylene materials are mounted into encasements 1 in flexible films such as rubber-coated cloth and buffuer materials 2' on sealing sheets 7 on the surfaces of bottoms in the encasements 1. Spaces 8 are formed to the buffer materials 2 so that the buffer materials 2 do not interfere mutually when the encasements 1 expand and round, and pressure is divided. Such encasements 1 in flexible films are arranged on a revered section 6 in the direction that crosses a river, a fluid is sent into the encasements 1 to expand and erect the encasements, and the fluid is discharged from the inside of the encasements to contract and bring down and erect the encasements.
