In general, retaining wall structures are installed on slopes such as housing sites and mountain bases that form boundaries with roads, and are constructed to prevent them from collapsing due to natural conditions such as earth pressure and rainwater. Such a retaining wall structure may be divided into a retaining wall structure using natural stone, a retaining wall structure using cement bricks, and the like, and a retaining wall structure using concrete, depending on the type.

Recently, a retaining wall structure using concrete is constructed in consideration of shortening the construction period and economical aspects. However, unlike at the foot of a mountain or roadside, when a retaining wall structure is installed on a residential site in the fill part of a large-scale housing site, natural stone construction, ecological landscaping, etc. Eco-friendly design is reflected in a wide range.

The retaining wall structure using natural stone blends well with the surrounding natural environment. However, natural stone (or decorative stone) is not easy to stack because it has an atypical shape. In addition, by resisting earth pressure due to the weight of natural stone, it is vulnerable to earthquakes, and construction safety is deteriorated due to collapse. Therefore, there is a need for a method of constructing a retaining wall structure that can more stably construct atypical natural stone.

As the background technology of the present invention, as Korean Patent Registration No. 10-0400170, a 'retaining wall structure using natural stone' is proposed. It includes a plurality of decorative stones arranged in multiple tiers so that the entire surface is exposed to the outside; a rear frame positioned at the rear of the plurality of decorative stones and installed long in the vertical direction according to the height of the plurality of decorative stones arranged in multi-tiered layers; a plurality of support bars interconnecting each decorative stone and the rear frame to support each decorative stone; a bottom frame disposed buried in the ground below each of the decorative stones; Including an anchor for interconnecting and supporting each of the decorative stones and the bottom frame, it is possible to maintain stability and rigidity after construction. However, in the background art, the decorative stone disposed on the lowermost side is fixed to the bottom frame by passing the rubble layer through the anchor, but there is no connection control means capable of responding to the change in the distance between the decorative stone and the rear frame, so the workability is poor. In addition, the method of fixing by installing an anchor at the bottom of the decorative stone also has a problem of poor workability.
