SOIL ECO GRASS RETAINING WALL STRUCTURE AND CONSTRUCTION METHOD THEREOF USING L-TYPE FRAME

摘要

The present invention relates to a method for constructing a retaining wall structure formed by vertically stacking unit structures consisting of an L-shaped frame, which is composed of multiple L-shaped steel wires and multiple horizontal steel wires, and a bottom reinforcing member, which is horizontally connected to the horizontal steel wires of the L-shaped frame. The method for constructing a retaining wall structure comprises the steps of: forming an L-shaped frame first by preparing multiple L-shaped steel wires having hooks formed at equal intervals on the end thereof which forms a horizontal part and preparing multiple horizontal steel wires having hooks formed at equal intervals on both ends thereof; mounting a mesh mat, which is a mat for preventing the flow of earth and sand, on the back surface of the L-shaped frame and mounting a vegetation mat, which consists of jute woven fabrics, vegetation paper, seed fertilizer moisturizers, and biodegradable nonwoven, on the back surface of the mesh mat; installing a bottom reinforcing member, which is a grid, in the hook of the horizontal part of the L-shaped steel wires after mounting the vegetation mat; banking and hardening the ground after installing the grid; stacking the L-shaped frames by repeating the above process depending on the height of a retaining wall after hardening the ground; and mounting a clay block on the uppermost part of the L-shaped frame. The method for constructing a retaining wall structure according to the present invention can improve the stability of a retaining wall structure without using concrete, reduce construction period and costs, be environmentally friendly, and make maintenance easy by being applied to various slopes using the unit structure of the L-shaped frame and the bottom reinforcing member, which has a simple structure without a separate reinforcing member.
