The present invention relates to a proximity block retaining wall in which a continuous through hole in a vertical direction is formed, and a construction method thereof. Specifically, the hollow part of the hollow block having a hollow portion in the hollow block provided with a hollow part in stacking blocks in sequence to form a retaining wall Since it is constructed to communicate vertically in the vertical direction of the plant, a vegetation earth and sand portion for vegetation can stick to the inside of the block can be formed to form an environmentally friendly retaining wall and reduce the weight of the block to improve workability. The present invention relates to an access block retaining wall having a new structure and a construction method thereof.

In the conventional general access retaining wall, as shown in FIG. 1, the beam 300 is installed vertically, and the earth plate 301 is installed on the rear surface of the beam 300, and then the blocks are formed between the beams 300. It has a structure which piles up the earth and sand on the back surface of the said earth plate 301, inserting and installing 302. In particular, the inlet retaining wall may be constructed using a structure for assembling a large block or panel.

However, in the case of such a conventional proximity retaining wall, since the block 302 is in the form of a single block, the weight is large, and accordingly, the block 302 is lifted up and sandwiched between the beams 300, or the beam is stacked. There exists a problem that the workability at the time of comprehensive lamination | stacking is very bad. In addition, aesthetically, the beam is exposed to the front surface, or due to the laminated structure of a large concrete block to create a dignified atmosphere or depressed atmosphere. In particular, the access retaining wall is often installed on the front side of the cut slope due to its structure, but since most of the cut slopes are on the roads or slopes of the apartments in the mountainous areas, environmental friendliness and good aesthetics are strongly required.

As the level of demand for environment and aesthetics increases, block reinforced retaining walls are used instead of the conventional concrete retaining walls. This is because the block-type reinforced earth retaining wall uses a small block, which is aesthetically advantageous because the weight of the unit block is small and the upper and lower blocks are stacked alternately.

However, in the front of the cut slope, etc., the reinforcement (grid) that is installed on the rear surface of the reinforced earth retaining wall is often insufficient. After reinforcing the back slope separately, the construction cost is high because the block retaining wall is installed as the concept of the finishing retaining wall.

In this case, the access retaining wall is advantageous because it does not need to lay a reinforcing material (grid) on the back ground, which is subject to many limitations due to the problems described above.

The present invention was developed in order to overcome the limitations and problems of the conventional proximity retaining wall as described above, by using a hollow block can reduce the weight of the block to improve the workability, by stacking the upper and lower hollow blocks alternately When viewed from the front, the block-like reinforced earth retaining wall produces the same aesthetics, and furthermore, despite the staggered laminated structure, the hollow part communicates with the retaining wall up and down so that the soil for plant planting can be easily secured inside the wall.
