Description

Structure of retaining wall having a possible planting for cutting slope}

The present invention relates to a retaining wall structure that is formed on a slope such as a cut slope, and more particularly, the installation is simple, and the stability of the slope such as a cut slope is effectively secured, thereby improving the rigidity of the retaining wall, and greening is possible through planting. The present invention relates to a plantable cut slope retaining wall structure having high Mars and high commerciality.

In general, slopes such as cut slopes exist mostly in riversides, lakes, or hills (flats, apartment complexes, etc.) or roads where roads are constructed.

Since the cut slope is formed by artificial cutting work, the slope is unbalanced and dangerous, and because the cohesive force of the soil is weak, it is easy to break down when it rains a lot or causes a situation, so the retaining wall is constructed around the cut slope. It prevents the back from being lost or happening.

As a plan for reinforcing slopes such as cut slopes, reinforced concrete retaining walls have been widely used in Korea, which not only consumes enormous cost and time for forming and curing the reinforced concrete structure, but also enormous cost for excavation and fill work. In addition, since there are many limitations for large-scale cutting work, about 15 years ago, the technique of constructing retaining wall by embedding soil in the anchor bolt site while constructing the structure in which the anchor bolt is integrated was introduced in Japan. It is implemented. However, this reinforcement method also has a disadvantage in that a large amount of cost is consumed in gulting and filling work, and the structure as a whole becomes large.

In order to improve this problem, structures of retaining walls are formed by stacking retaining wall blocks coupled with steel reinforcement materials and reinforcing cut slopes through such retaining wall structures.

That is, as disclosed in Korean Patent Publication No. 0372821, the retaining wall structure for reinforcing a conventional cut slope is provided with a foundation concrete thereafter after digging along the bottom contour at a predetermined distance from the cut slope, While reinforcing retaining wall blocks are piled up on the foundation concrete, the backing soil is laid between the cut slope and the retaining wall blocks, and the retaining wall blocks are fastened with locks, such as steel rod reinforcement, at regular intervals. The cut slopes were reinforced by filling soil in the empty spaces between the slopes or by pouring concrete to form retaining walls.

However, the retaining wall structure configured as described above has a steel rod stiffener in order to connect the retaining wall block to the steel stiffener installed in the vertical direction on the cut slope when installing the steel reinforcement in the vertical direction on the cut slope having a certain inclination angle to improve reinforcement. It requires a coupler that can change the direction of tension. Therefore, as the coupler installation work is added, there is a problem that the workability is lowered and the construction cost is increased. In addition, there is a problem that it is difficult to effectively ensure the stability of the cut slope because the transfer of force from the rod reinforcement to the retaining wall block is not effective because the direction of the tensile force of the steel reinforcement is changed.

In addition, in the retaining wall structure configured as described above, the vegetation of the retaining wall is difficult and the fastening portion of the steel rod reinforcement is exposed on the front surface of the retaining wall block, which is vulnerable to corrosion and harms the appearance.

The steel rod reinforcement coupled to the cut slope in a vertical direction is fastened in a straight line to the fastening portion of the connection block for planting, and is spaced between the space for the connection portion of the connection block for planting and the rear surface of the connection block for planting and the cut slope. Binding concrete is laid in space; The same basic unit retaining wall structure is formed on the base unit retaining wall structure, and the stacking retaining wall block corresponding to the stacking retaining wall block is stacked on the upper portion of the rear portion of the connection block for planting material in a plurality of layers to connect the planting block. A plantable cut slope retaining wall structure is provided, characterized in that the basic unit retaining wall structure is repeatedly formed in a stair shape with the planting part exposed.
