In general, a retaining wall structure refers to a wall formed on the entire surface of a slope, cut land, and bedrock formed on a housing site and roadside, etc. to prevent them from collapsing due to earth pressure or rainwater.

Conventional panel retaining walls are constructed in a laminated structure through temporary materials, which causes delays in construction, safety problems, and increases in construction costs due to the non-self-standing construction structure. In addition, the conventional retaining wall construction method inevitably requires that the cut-out area of the cut slope be wide for a stable structure, which may interfere with other people's land such as public land or private land other than the receiving site for earthwork. In order to achieve this, the land for construction must be purchased with excessive compensation, which in turn causes an increase in construction costs.
