2. Vegetation soil pack (20, 30, 40).

The vegetation layer consists of three layers, from the bottom to the base layer - nutrient supply layer - germination layer, so that greening work is easy and greening is maintained for a long time. packaged and used.

That is, the vegetation soil pack is divided into a type 1 vegetation soil pack (20), a type 2 vegetation soil pack (30), and a type 3 vegetation soil pack (40), and these vegetation soil packs (20, 30, 40) are geotextile fibrous bags or meshes. It is a composition in which vegetation soil of different composition is filled inside for the optimization of structural stability and economic feasibility of the slope. Of course, if there is no loss of vegetation layer material, it can be constructed in bulk (unpackaged state) without using a geotextile bag or mesh.

In the present invention, the vegetation layer material for the vegetation layer is classified according to the use of the base layer - the nutrient supply layer - the germination layer. .

The first-class vegetation soil pack 20 is a pack made by mixing all of soil, seeds, and nutrient soil as a germination material, and is minimally installed only on the surface of the slope to secure economic efficiency.

Compared to the first-class vegetation soil pack 20, the second-class vegetation soil pack 30 is composed of soil and nutrient soil excluding seeds, that is, materials for nutrient supply, so that the seeds of the first-type vegetation soil pack 20 can be stably vegetated. It is a vegetation-based pack that supplies and stabilizes.

The three-type vegetation soil pack 40 is a basic material and consists of some soil and mostly aggregate (crushed stone). It is a pack for securing structural stability by increasing shear friction resistance by being installed directly above it.

According to the present invention, from the bottom of the maintenance area (1), a vegetation layer of the type 3 vegetation soil pack 40 - the type 2 vegetation soil pack 30 - the type 1 vegetation soil pack 20 is stacked on top of it, and it is in a natural state It is the principle that the slope is restored to the most suitable shape for the soil structure in

On the other hand, the type 2 vegetation soil pack 30 and the type 3 vegetation soil pack 40 may include soil cement as an internal material to increase shear friction resistance. Soil cement is used as a mixing ratio of 2 to 10 parts by weight based on 100 parts by weight of the total of 2 or 3 types of vegetation soil pack (30, 40).

On the other hand, the vegetation layer is possible with two vegetation soil packs, for example, a two-layer structure of a base layer and a vegetation layer is also possible by combining the above-mentioned type 1 and type 2 vegetation soil packs 10 and 20 into one.

Alternatively, the seed spray process of using only the 2 and 3 types of vegetation soil packs (20, 30) and planting seeds in only the 2 types of vegetation soil packs (20) is required.

Type 1 within 3 types of vegetation soil packs (20, 30, 40) can be manufactured and used at the construction site, and as shown in FIG. 7 as an example of a field manufacturing facility, the field manufacturing vehicle 200 can be both self-propelled and towed A hopper 210 that puts vegetation materials (such as soil, nutrients, gravel, seeds, etc., according to the type of vegetation soil pack, etc.) into the hopper 210, and the vegetation bag 220 is mounted at the lower discharge end of the hopper 210. As a transfer means for transferring the vegetation material falling from the hopper 210 into the vegetation bag 220 so as to be filled and the filling of the vegetation material is completed, for example, the conveyor 230, through the conveyor 230. Including a compactor 240 for compacting the transferred vegetation bag, the vegetation soil pack (20, 30, 40) is manufactured.

3. Wire mesh (50).

As a loss member, the wire mesh 50 covers and protects the first-class vegetation soil pack 20 so that the vegetation layer is not lost, and is fixed through the external fixing plate 60 and additionally the edge is the periphery of the maintenance area (1). Can be anchored on slopes.

In order to prevent the loss of the first-class vegetation soil packs 20 without using the loss member, all the first-class vegetation soil packs 20 must be fixed by the external fixing plate 60, but by using the loss member, the first-class vegetation soil packs are used. Even if (20) is installed in a large quantity, it is possible to fix it through the wire mesh 50, and the wire mesh 50 is fixed with a small number of external fixing plates 60 less than the type 1 vegetation soil pack 20, so eventually It is possible to prevent the loss of all type 1 vegetation soil pack (20).

4. External fixing plate (60).

The external fixing plate 60 is to fix the vegetation soil packs 20, 30, and 40 in a construction state, and the use of the tensile force of the tension member 70 will be described as an example.

The structure of the external fixation plate 60 is, for example, a flat plate shape, and of course it is not limited to the shape. In particular, the external fixation plate 60 should not prevent the seeds of the first-class vegetation soil pack 20 from germinating, so it is preferable to have porosity. .

As a method in which the external fixing plate 60 does not block the germination of seeds, it is also possible to secure a large space between them by minimizing the size.

The external fixing plate 60 should be configured such that the above-ground end of the tension member 70 is fixed (fixed), for example, as shown in FIG. A method in which a ball 62 is formed and the above-ground end of the tension member 70 is inserted into the anchorage hole 62, and then a wedge 71 is inserted around the periphery so that the wedge 71 is wedge-coupled to the anchorage hole 62 There is a method of fastening the nut 72 after forming the bolt 72 on the ground side end of the tension member 70 as shown in FIG. 4B , passing the bolt 72 through the fixing hole 61 .

The external fixing plate 60 may include spikes inserted into the first-class vegetation soil pack 20 as needed.

The external fixing plate 60 may be applied in the same quantity to be connected 1:1 with the internal fixing plate 10 or a smaller quantity than the internal fixing plate 10 may be applied.

5. Tension member (70).

The tension member 70 pulls the external anchorage plate 60 through a tensile force so that the vegetation layer maintains stability, and the ground end must be fixed to the external anchorage plate 60, but the underground end is the inner anchorage plate 10 or It is possible to be fixed in the vegetation layer or underground of the maintenance area (1).

The internal fixing plate fixing type connects the end of the tension member 70 to the tension member connection part 12 of the internal fixing plate 10 .

As shown in FIG. 5, the vegetation layer fixing type is to fix the end of the tension member 70 to the three-type vegetation soil pack 40 disposed at the bottom of the vegetation layer, and the underground fixing type anchors the end of the tension member 70 in the ground. is to be fixed, and it is possible to omit the internal fixing plate 10 through these two methods.

The internal anchoring plate 10 is installed at an appropriate distance from each other so that the first to third types of vegetation soil packs 20, 30, and 40 installed in the subsequent process are not lost and the stack is maintained. When the shear key 13 is applied, the shear key 13 is inserted and fixed in the maintenance area 1, so that the internal fixing plate 10 secures stability through shear force.

(S20) Tension member connection.

One end of the tension member 70 is fixed to the tension member connection part 12 of the internal fixing plate 10 to connect the tension member 70 to the internal fixing plate 10 .

At this time, the tension member 70 may be prepared by cutting it to a sufficient length in consideration of the position of the external fixing plate 60 from the bottom of the repair zone 1 .

(S30) Vegetation layer construction.

Install the 3-type vegetation soil pack 40 on the internal anchoring layer formed by the internal anchoring plates 10, install the 2-type vegetation soil pack 30 on the 3-type vegetation soil pack 40, and finally install the 2-type vegetation soil pack ( 30) Install the 1st type vegetation soil pack 20 on the top to construct the vegetation layer.

When constructing the vegetation layer in this way, the tension material 70 is not buried.

(S40) Wire mesh installation.

A wire mesh 50 is installed on the type 1 vegetation soil pack 20 . If the wire mesh 50 is not lost until the external fixing plate 60 is installed, a separate fixing operation is not performed.

(S50) External fixing plate installation and tension member connection and tension.

A plurality of external fixing plates 60 are installed on the wire mesh 50 and the ends of the tension members 70 are penetrated through the fixing holes 62 of the external fixing plates 60 and then fixed with wedges 71, or tension members. After the bolt 72 of (70) is passed through the fixing hole 62, the nut 73 is fastened to fix it.

By tensioning the tension member 70, the 1st to 3rd type vegetation soil packs 20, 30, and 40 are compressed, and eventually the 1st to 3rd type vegetation soil packs 20, 30, 40 are firmly supported in the direction in which they are gathered, thereby forming vegetation. The layer is stabilized. In addition, the 1st to 3rd types of vegetation soil packs 20, 30, and 40 generate a force toward the slope through their own weight and are stably installed in the repair area 1 of the arc destruction. In addition, as the seeds of the type 1 vegetation soil pack (2) germinate and grow, they are connected to the slopes around the vegetation layer through their roots and have a sense of homogeneity, resulting in greater stability.

When the installation of the tension member 70 is completed, the portion protruding from the external fixing plate 60 is cut and finished.

Through the above process, the maintenance greening method of the present invention is completed.
