The present invention relates to a retaining wall structure, and more particularly to an improvement of a vegetation retaining wall structure for greening.

In general, retaining walls are used in a wide variety of civil engineering and landscape applications such as supporting slopes and embankments of highways or railways, and supporting sound barriers.

In recent years, many methods for constructing retaining walls without using environmentally harmful elements such as cement and reinforced concrete have been developed to emphasize eco-friendliness, and as a representative example, Korean Patent Application Publication No. 2000-71265 (published: 2000.11.25.) "Retaining wall structure with interlocking retaining wall construction units and a method of constructing them".

Korean Patent Laid-Open No. 2000-71265 has an advantage of improving the durability and appearance of the retaining wall with little use of harmful elements such as cement and reinforced concrete.

In addition, the above-mentioned prior art inserts the end hole of the geogrid sheet for fixing the backfill and retaining wall structure, which is filled in the back of the retaining wall constructed with the soil, and such a structure is provided. The sharp protrusions of the connecting members do not hold the geogrid sheet sufficiently strong. In particular, when reinforcing the retaining wall structure for greening the existing RC (reinforced concrete) retaining wall, it is not enough to be supported by the connecting line attached to the anchor bolt installed in the existing RC retaining wall by the protrusion of the RC connecting member.

Accordingly, an object of the present invention is to provide a vegetation retaining wall structure that can further improve the fixing force and the bearing capacity of the retaining wall structure, have flexibility and structural strength, and can be eco-friendly greening.

Another object of the present invention is to provide a vegetation retaining wall structure for greening the structure is vital.
