The present invention relates to a reinforced earth retaining wall, and in particular, by using a vertical member, a horizontal member and a joint member and a biasing member, a plurality of unit retaining wall frames having a box shape inclined in the front and rear, vertically, left and right to the front of the retaining wall The slanted construction increases the constructability and rigidity of the steel retaining wall as a whole, and reduces the objection to steel by selectively joining the decorative member made of wood or patterned steel plate to the front of the inclined unit retaining wall frame. To harmonize with the surroundings.

In general, retaining walls have been constructed to prevent the slopes of ground or earth piles from building and civil engineering from collapsing due to external climatic factors, soil pressure and other causes.

The retaining wall was constructed by laying the foundation on the lower part of the cut surface, placing the formwork and reinforcing bar on the upper part, and then placing concrete on the installed formwork and drying it for a certain time.

As many processes are required to obtain a single retaining wall on such cut surfaces, there is a problem of delaying air in the retaining wall construction, resulting in a cost increase, and another problem that is incompatible with the surrounding environment due to the inherent gray color of the retaining wall. There was this.

In order to solve such a problem, the retaining wall construction method and structure of the patent registration No. 527293, which is registered and registered by the applicant, have been proposed. The proposed retaining wall structure has a long vertical post (3) as shown in FIG. Horizontal members 31 are coupled to both upper and lower ends of the joints, and one side ends of the joint members 32 having different lengths toward the front surface of the vertical post 3 are coupled to have a predetermined height interval, respectively. A front post 33 having a height or a length corresponding to half of the vertical post 3 is coupled to the other end of the member 32, and the connecting member 34 is connected or coupled to the front post 33. Through it is coupled to have a constant slope. In addition, the first and second screens 35 and 36 are coupled between the front posts 33 that are inclined.

However, the retaining wall having such a construction is constructed in a state where the retaining wall and the retaining wall are separated in the process of being installed in a step shape on the battalion surface, so when rainwater flows down through the rainy season during the rainy season, There was a problem that the retaining wall collapsed due to soil leakage.

And as the retaining wall itself is large, there is another problem that requires a long time for assembling and constructing one retaining wall in the field, so that two front posts 33 are vertically coupled to one retaining wall. As a solution for this, a large amount of joint members 32 are required in the process of coupling a plurality of joint members 32 having different lengths between the vertical posts 3 and the front posts 33, and a plurality of connection members. In the process of obtaining (34), it takes a lot of time as the length is different, and the process of combining them in the field also has another problem that requires much time and labor.

In addition, all posts, joint members, and screens constituting the retaining wall are compulsorily induces a feeling of rejection of the steel exposed to the front surface of the retaining wall, and at the same time, there is a problem in that it does not harmonize with the surroundings.

The present invention was created to solve the above problems, by using a vertical member, a horizontal member, a joint member, and a biasing member, the retaining wall by combining a plurality of unit retaining wall frames having a box shape with the front inclined in a vertical direction. By inclining the front surface of the wall, the construction and rigidity of the steel retaining wall as a whole can be further increased, and the decorative member made of wood or patterned steel plate is coupled to the front surface of the inclined unit retaining wall frame, thereby reducing the objection to steel. The purpose is to provide a reinforced earth retaining wall that can harmonize with the surroundings.
