In particular, the H beams supported by the anchor tie are disposed in front of the cut portion, and the shelf blocks are mounted at predetermined heights of the H beam to provide structural stability. The present invention relates to greening retaining walls using H-beams and shelf blocks to realize environmentally friendly civil structures by creating a growing environment of plants through soil filling parts exposed between layers of neighboring shelf blocks up and down at the same time.

In Korea, when constructing retaining walls such as roads and rail slopes, slopes of park areas, river banks, and coastal roads, priority is placed on the stability of the soil and the protection of the slopes. Retaining walls made of concrete panels are the mainstream.

As mentioned above, the retaining wall, which finishes the entire front wall with a concrete surface, greatly damages the urban landscape by providing a grayish appearance that is not at all in harmony with the surrounding natural environment. It is a factor that worsens the natural ecological environment.

In addition, although the drainage hole is drilled for the drainage of the front wall made of concrete and backfilled with gravel, the drainage is not made smoothly, and there is a risk of collapse due to water pressure. There was a great difficulty.

In recent years, as the above-mentioned environmental problems are seriously recognized and people's desire for environment-friendly urban landscapes is increasing, retaining wall construction that introduces vegetation to create a natural ecological environment has been actively attempted.
