Document Type and Number:
Japanese Patent JP3631377
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To provide a method capable of executing construction and repair of levee, etc., in a place where a large water current clashes within a short period of time.
SOLUTION: A hanging contraction rope is inserted in the mesh of a net around the circumferential edge of an opening section in a net bag having 15-80% of ductility formed by using a single or more net textures knitted with a synthetic fiber yarn with 1-10 mm of wire diameter, an inside bag of the net bag consisting of an outside bag 1 providing an opening contraction rope 4 around a hanging rope 3 and the inside bag formed by cloths located at the inside of an outside bag body is filled with ready mixed concrete mixing aggregate such as cobble stone, rubble, lumps of concrete, etc., with cement to bind the opening of the inside bag with a rope to close the net bag closing the opening of the outside bag 1 with the opening contraction rope 4 and filled with ready mixed concrete is hung up with the hanging rope 3 and is located at a specific position in the water to form a concrete construction in the water.
