Description

Anchoring structure of afforestation Retaining-Wall}

The present invention relates to an anchoring structure of a shelf greening retaining wall for creating a growth environment of a plant through soil filling parts exposed between layers of adjacent shelf blocks up and down, and in particular, a chair that maintains the height of the shelf block. The present invention relates to an anchoring structure of a shelf-type greening retaining wall that allows the block to be easily and firmly connected to the anchor tie embedded in the sloped surface of the retaining wall.

In Korea, when constructing retaining walls such as roads and rail slopes, slopes of park areas, river embankments, 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.

Recently, a block-type greening retaining wall, such as Korean Patent Registration No. 10-0393515, has been disclosed as one of the retaining walls introducing vegetation.

As shown in Figs. 1A and 1B, the block-type greening retaining wall according to the prior art has shelving blocks 2 extending in the horizontal direction on the upper part of the basic concrete part 1, and a horizontal connecting groove 3 in the front part. The retaining wall is constructed by backfilling the formed chair blocks 4 step by step to form a front wall and backfilling the stacked blocks, and the rear part of each row in which the chair blocks 4 are stacked up and down. There is an anchor tie fixed deep inside the ground at every predetermined height and a forced H beam (5) fixed to the anchor tie while the lower part is embedded in the foundation ground to reinforce the structural strength corresponding to the main earth pressure, the chair block (4) The back side of the beams is provided with the technical structure characterized in that the H beam 5 is supported by being connected to the H beam 5 with a bolt 6 and a nut 7 in a state in which it faces the front surface of the H beam 5.

The block-type greening retaining wall is exposed to the backfill soil between the upper and lower shelf blocks, and provides an environment where plants can grow through the exposed portion of the backfill soil, thereby realizing environmentally friendly civil engineering structures. Doing.

However, the block-type greening retaining wall has a problem in that the work of fixing the chair block, the H beam and the anchor tie is very poor.

In other words, the block-type greening retaining wall according to the prior art is anchored in the slope of the back surface of the retaining wall and the H-beam connected to the anchor tie prior to stacking the chair block and the shelf block constituting the retaining wall After fixing, the chair block is fixed by connecting to the H beam.Because of the construction error of the anchor tie, the anchor tie and the H beam are connected and fixed by bending the tip of the anchor tie when the H and beam block are connected and fixed. There is a problem that the work is very cumbersome and difficult to do such that the workability is low and the air takes a long time.

In addition, since the chair block is fixed to the anchor tie via the H beam, not only excessive construction cost is required, but also the chair block stacked on the front of the H beam is fixed to the H beam with bolts and nuts for each layer. However, this alone has a deficiency in the structural stability of the lack of fixing ability.

Accordingly, the present invention is the top and bottom of the anchor tie and shelf blocks that are embedded in the ground of the retaining wall back in the conventional construction of the planting retaining wall for creating a growth environment of the plant through the soil filling portion exposed between the layers of the neighboring shelf blocks up and down It was invented to solve the problems that appeared in the construction of the connection of the chair block to maintain the fault height.

Therefore, the purpose of the present invention is to factory-manufacture only the front part of the chair block and absorb the construction error for the connection part of the anchor tie while directly connecting and fixing the anchor tie and the chair block without using the H beam. By on-site construction with non-shrink mortar casting, not only the construction cost is required but also the construction is easy to provide a structural anchoring structure of the shelving greening retaining wall that can secure a solid fixing force.
