VEGETATION TYPE NON WOVEN FABRIC, REVETMENT STRUCTURE AND REVETMENT CONSTRUCTION METHOD USING THEREOF

摘要

The present invention relates to a vegetative non-woven fabric for preventing soil drain in a river and growing plants, and a revetment structure and a method for revetment construction using the same. The vegetative non- woven fabric comprises a punched non- woven fabric having perforated thereon in such a manner as to be spaced apart from one another at predetermined intervals; a coir roll matt laid on the punched non-woven fabric; and a wire-screen laid on the coir roll matt. The revetment structure comprises a weight of a predetermined size buried at the center of the ground of a river of which the water flow is suspended, and having a screw type steel rod vertically fixed on the upper surface thereof, wherein the upper end part of the steel rod is to be projected above the ground; a vegetative non-woven fabric as described above; a wire rope; and a nut. The method of revetment construction comprises the steps of: installing a large-sized concrete base stone under the ground; fixing a cross-shaped concrete connecting member; fixing small-sized concrete blocks; burying the large-sized concrete base stone, the cross-shaped concrete connecting member and the small-sized concrete blocks in the earth; laying a punched non- woven fabric; laying a coir roll mat; laying a wire-screen; fixing a wire rope; and fastening a nut to the screw type steel rod.
