Retaining wall using stone for landscape}

The present invention relates to a retaining wall, and more particularly, to a retaining wall applied to the cut portion constituting the front surface with a stone for landscaping.

Civil engineering or construction sites generally need to consider reinforcement of the cut surface of the cut formed by cutting the rock or the ground, or the slope of the fill section with respect to the cut created between the different altitudes in the process of laying the ground. .

The cut section is a structure with respect to the inclined surface having a slope formed by an arbitrary incision, and the fill section is a structure with respect to the inclined surface formed with an altitude difference in the process of filling.

Here, the cutting surface and the inclined surface may be presented a construction method for reinforcement in various ways. Among them, the reinforcement method should be applied to the cut section considering the landscape considering the external aesthetics as well as safety and economy.

In general, in order to reinforce the inclined surface of the cut portion, a retaining wall structure using concrete pouring or a stone wall structure using mountain stones (natural stone) may be presented.

However, the retaining wall structure using concrete pouring lacks flexibility and variability corresponding to shapes of slopes and rocks to be installed. And, in order to solve the flexibility and variability, a support base is required, but a considerable space is required to secure the support base. In addition, the securing of such space requires a lot of backfilling work, and thus the construction period is extended, and construction costs are high. In addition, in the case where a partial breakage of the retaining wall structure occurs in the future, repair thereof is difficult, and it is difficult to satisfy the landscape aspect in consideration of aesthetics.
