Description

Retaining Wall Structure

The present invention relates to a retaining wall structure, and more particularly, to form a retaining wall frame using steel and wood, and retaining wall frame by combining a member made of standardized steel and wood manufactured separately in a simple fastening method or inserting method in the field. This invention relates to a retaining wall structure that can be constructed by adjusting the height and width of the structure by combining the retaining wall frame and the retaining wall frame.

In general, the retaining wall structure refers to a wall that is constructed so that soil does not collapse in response to earth pressure, and is an artificial structure for preventing ground collapse that occurs when the soil is stacked or the mountain is sharper steeper than a stable slope of the ground surface.

In particular, a retaining wall structure in front of a single-layered ground cut out to prevent soil from entering the road from an incision that cuts a portion of the mountain to form a highway or a mountain road, or to create a landscape environment around a building or sculpture. After stacking, the retaining wall construction is performed through a layering method such as backfilling with gravel and soil between the retaining wall and the cut single-layered ground.

For example, as such a retaining wall structure, there is a reinforcement soil retaining wall which is constructed between a grid-shaped reinforcement (Greido, Tieback, etc.) which is interposed between a block formed to a certain size and a block to be laminated up and down and laid in the transverse direction. .

In addition, the retaining wall frame is formed by combining the horizontal frame between the vertical frame and the vertical frame made of steel, and the retaining wall frame is arranged vertically and horizontally, and then the stones are stacked on the front surface and filled with internal filling material inside. There is a formed steel retaining wall. The steel frame retaining wall has a strong advantage against the back pressure due to the excellent water permeability of the inner filling material, and is being constructed a lot because of the good field applicability and construction.
