The reinforcement earth blocks 100 may have a predetermined shape and may be stacked and arranged. In the illustrated drawing, the reinforcement earth blocks 100 are simply stacked. The above-mentioned reinforcement soil blocks 100 may be zigzag stacked. In the process of stacking the reinforcement soil blocks 100, a part of the grid layer 220 may be disposed between the stacked surfaces to form the soil layer 200. The reinforcement soil blocks 100 have at least one protrusion and a groove formed at the front and the rear thereof, respectively. Accordingly, in the process of stacking the reinforcement soil blocks 100, the grid layer 220 is disposed between the front surface of one reinforcement soil block and the rear surface of the other reinforcement soil block, so that the grid layer 220 is formed of the reinforcement soil blocks 100. The projection and the groove are arranged between the engagement. As a result, the reinforcement earth blocks 100 of the present invention may obtain a bearing force in a predetermined direction by the grid layer 220. In addition, the wire reinforcement 230 formed on the grid layer 220 to the reinforcement earth block 100 of the present invention may be connected or fixed. Accordingly, the reinforcement soil blocks 100 may have a bearing force in the vertical direction through self-protrusion and groove coupling, as well as secure the bearing force in the horizontal direction by connecting the grid layer 220 and the wire reinforcement 230. .

The rocky terrain 300 is a terrain composed of rock walls, rocks, and the like, forming a mountain slope. The rocky terrain 300 may be formed by extending a portion to an area adjacent to the road 11. Alternatively, the particular rocky terrain 300 may form a cliff with respect to the road 11. The rock terrain 300 of the present invention may be at least partially buried by the soil layer 200 described above. In particular, the wire reinforcement 230 and the anchor 240 included in the soil layer 200 may be coupled to the rock wall or the rock included in the rock terrain 300. The wire reinforcement 230 and the anchor 240 fastened and fixed to the rocky terrain 300 will be described in more detail with reference to the accompanying drawings.

The soil layer 200 is formed between the reinforcement soil blocks 100 and the rocky terrain 300 to support the reinforcement soil blocks 100 and to suppress soil movement of the rocky terrain 300. The soil layer 200 may be formed by stacking the fill layer 210, the grid layer 220, and the wire reinforcement 230 in the lamination process of the respective reinforcement soil blocks 100.

For example, when the reinforcement soil blocks 100 are arranged in a row in a predetermined area next to the road 11, the fill layer 210 is formed between the reinforcement soil blocks 100 having a height of 1 step and the rocky terrain 300. It may be formed preferentially. The fill layer 210 may be composed of a mixture of soil, gravel, sand and the like. The fill layer 210 may be formed at the same height as the reinforcement soil blocks 100 having the first height. In this case, in order to suppress ground subsidence of the fill layer 210, a material constituting the fill layer 210 may be embedded and then the work may be performed at a predetermined pressure.

Meanwhile, when the fill layer 210 is formed, the grid layer 220 formed of a mesh of fiber material is disposed to cover the entire surface of the fill layer 210 and the reinforcement soil blocks 100. In this case, portions of the grid layer 220 disposed on the reinforcement soil blocks 100 may be disposed so that protrusions formed in the reinforcement soil blocks 100 may be exposed to the outside. In addition, a portion of the grid layer 220 that is disposed in the rocky terrain 300 direction may be fixed to the anchor 240 installed in the rocky terrain 300. As described above, the grid layer 220 is configured in the form of a mesh, so that each opening area of the mesh can be fixed to the protrusions of the reinforcement earth blocks 100 while being easily fixed to the protrusion of the anchor 240.

When the grid layer 220 is placed on the fill layer 210 and the reinforcement block 100, the wire reinforcement 230 is placed on a portion of the fill layer 210. At this time, one end of the wire reinforcement 230 is fixed to the reinforcement earth block 100, the other end may be fixed to the anchor 240 formed in the rock terrain (300). One end of the wire reinforcement 230 may be provided in a structure that can be fastened to the reinforcement earth blocks 100 to be fixed to the reinforcement earth blocks 100, for example, in a ring shape. In addition, the other end of the wire reinforcement 230 may also be provided in a ring shape to be fixed to the protrusion of the anchor 240. The wire reinforcement 230 connects the anchors of the reinforcement soil blocks 100 and the rocky terrain 300, but is disposed on the fill layer 210. Alternatively, the wire reinforcement 230 may be disposed below the fill layer 210. At this time, the primary function of the wire reinforcing material 230 is to improve the bearing capacity in the horizontal direction of the reinforcement earth block 100, and serves to fix the fill layer 210 when disposed above the fill layer (210). can do. Accordingly, the length of the wire reinforcement 230 disposed between the reinforcement soil blocks 100 and the rocky terrain 300 may be formed to have a length similar to the distance between the reinforcement soil blocks 100 and the rocky terrain 300. Meanwhile, the wire reinforcement 230 may have a structure in which the other end is fixed to one anchor 240 disposed on the rocky terrain 300, and one end thereof may be fastened to the plurality of reinforcement block 100. Accordingly, the wire reinforcement 230 may adjust the length of the wire reinforcement 230 in the process of fixing the end to each of the reinforcement soil block 100 and then coupled with the anchor 240 disposed on the rock terrain (300).

After the fill layer 210, the grid layer 220, the wire reinforcement 230, and the like are disposed, the reinforcement soil blocks 100 may be stacked again to stack additional reinforcement soil blocks.

It may include a second type soil layer composed of a fill layer 210 and a grid layer 220 from which the reinforcement and the anchor 240 are excluded. In addition, if it is possible to secure a sufficient width of the fill layer 210 to place the grid layer 220 of an appropriate size according to the height of the step laminated in the reinforcement soil block structure 20, the separate wire reinforcement 230 and The earth layer 200 may be formed in a form in which the anchor 240 is excluded.

In other words, in the soil layer 200 of the present invention, the first type soil layer and the second type soil layer may be formed according to a predetermined position in the horizontal structure, and the first type soil layer according to a certain height in the vertical structure. And a second type soil layer may be formed, respectively. When the rocky terrain 300 is formed in an overhang structure, the first type soil layer may be formed at a stage of a predetermined height or more, and the second type soil layer may be formed at a stage of a predetermined height or less.

Meanwhile, the illustrated figure shows a structure in which the reinforcement soil blocks 100 are formed in four stages, but the present invention is not limited thereto. That is, the reinforcement soil blocks 100 may be formed in a higher stage or a lower stage according to the surrounding topography. In addition, in the above description, the reinforcement earth blocks 100 are arranged in one row to configure one end as an example, but the present invention is not limited thereto. That is, the reinforcement earth blocks 100 of the present invention may be assembled into a plurality of units using a fastening groove and a fastening rod as a single unit. Accordingly, one stage may be configured as the height of the plurality of reinforcement soil blocks (100). For example, when the two reinforcement earth blocks 100 are fastened and disposed as one end, the grid layer 220 and the wire reinforcement 230 are disposed and fastened between the two reinforcement earth blocks 100 in the height direction, respectively. Could be.

As described above, the reinforcement earth block structure 20 according to the exemplary embodiment of the present invention does not apply the first type soil layer including the wire reinforcement 230 and the anchor 240 and the wire reinforcement 230 and the anchor 240. The second type soil layer may be adaptively formed in the horizontal and vertical directions according to the characteristics of the terrain.
