Abstract

A retaining wall structure of the present invention is a retaining wall structure comprising soil bags, each including: top and bottom surface portions having the largest area among surfaces constituting a soil bag body; and long side surface portions and short side surface portions forming side surfaces of the soil bag body between the top and bottom surface portions, wherein each of the long side surface portions of the soil bags is arranged to face the ground, the soil bags are stacked such that the long side surface portions are in contact with each other in the vertical direction with respect to the ground, the soil bags are arranged such that the short side surface portions are in contact with each other in the lateral direction with respect to the ground, and auxiliary retaining walls that are respectively disposed behind the stacked soil bags are provided.

Description

Claims

1. A retaining wall structure comprising soil bags, in which each of the soil bags includes top and bottom surface portions having a largest area among surfaces constituting the soil bag, and long side surface portions and short side surface portions forming side surfaces of the soil bag between the top and bottom surface portions, wherein the soil bags are stacked such that the long side surface portion of the soil bag is arranged to face a ground, and the long side surface portions make contact with each other in a vertical direction with respect to the ground,the soil bags are arranged such that the short side surface portions make contact with each other in a lateral direction with respect to the ground, andthe retaining wall structure includes an auxiliary retaining wall disposed on a rear side of the stacked soil bags.

2. The retaining wall structure of claim 1, wherein a retaining wall obtained by stacking the soil bags is constructed such that soil bags of a second layer are located on a contact region of soil bags constituting a first layer.

3. The retaining wall structure of claim 2, wherein the auxiliary retaining wall includes a quarried stone layer including gravel, and a fixing net is provided on the quarried stone layer.

4. The retaining wall structure of claim 3, further comprising a connection plate disposed on the long side surface portions of the soil bags to increase bonding strength of the soil bags stacked in the vertical direction, wherein the connection plate has a smaller size than the long side surface portion of the soil bag, a plurality of conical protrusions are formed on each of top and bottom surfaces of the connection plate, and the conical protrusions are provided at mutually different positions on the top and bottom surfaces of the connection plate.

5. The retaining wall structure of claim 4, wherein the soil bag is formed such that a lateral side has a size of 30 cm, a longitudinal side has a size of 70 cm, and a height has a size of 15 cm, and soil formed by hardening gravel or on-site soil and a geogrid disposed on the soil are provided on a rear side of the auxiliary retaining wall.
