The greening base material 5 containing the same is sprayed.

[0015] Then, as shown in FIG.
After removing the surrounding protective sheet 3 to expose the surface of the surrounding ground 1, a mortar or concrete 6 is formed on the surface of the greening base material 5 in the form of a lattice having the ground 1 around the anchor member 2 as an intersection. Spray. The sprayed mortar or concrete 6 is in close contact with the surface of the ground 1 at the grid-like intersection 6A around the anchor member 2, as shown in FIG. 6, and as shown in FIG. 6 and FIG. At the other side, grid-like side portions 6B and 6C (FIG. 6 shows the vertical side 6B and FIG. 7 shows the horizontal side 6C) connecting the anchor members 2 cover the surface of the greening base material 5. It has been sprayed.

Therefore, the greening base material 5 is fixed so as to be pressed down on the surface of the ground 1 by the grid-like mortar or the side portions 6B and 6C of the concrete 6 which are in close contact with the surface of the ground 1 at the intersection 6A. Therefore, it is possible to prevent the collapse of the ground 1 and stabilize the protection,
The greening base material 5 is a grid-like mortar or concrete 6
Therefore, the root system of the plant to be planted can be spread over a wide area on the surface of the ground 1, and the plant can be continuously formed without being divided for each section (see FIGS. 7 and 3). Has good fixability. Furthermore, by growing the planted plant, the root system is extended over a wide area on the surface of the ground 1, and further prevention of collapse of the slope and protection stability can be achieved.

Are preferably arranged in a lattice pattern with the anchor member 2 as an intersection. In this case, it is preferable that the wire mesh 7 and the reinforcing bar 8 are fixed in position by the anchor member 2. The wire mesh 7 is covered after the greening base material 5 is sprayed, but the reinforcing bar 8 is arranged before the mortar or concrete 6 is sprayed and before the protective sheet 3 is coated if the anchor member 2 can be fixed in position. Is also good.

In the present invention, the greening base material 5
The spraying amount, thickness and composition of the mortar or concrete 6 to be sprayed in a grid form, and various conditions such as the spraying amount and thickness, grid spacing, composition, etc. are appropriately adjusted depending on the applied slope. .

In the above embodiment, when the mortar or concrete 6 is sprayed, the anchor member 2
The surrounding protective sheet 3 was removed, but a cut 3A was made in the protective sheet 3 as shown in FIG. 8 and opened to the outer greening base material 5 side as shown in FIG. After the mortar or concrete 6 is sprayed, the mortar or concrete 6 at the intersection 6A is sprayed.
Erosion of the greening base material 5 to the
Adhesion between the mortar or concrete 6 and the ground 1 at the intersection 6A can be maintained.

Further, when the slope is steep, as shown in FIG. 10, the shelf 9 having the same function as the terrace pocket as described in Japanese Patent Application Laid-Open No. 1-223218 is attached to the side portion 6C.
May be formed.

[0021]

According to the present invention, the anchor members are arranged on the slope in a vertical and horizontal manner at a predetermined interval, and the green base material is sprayed on the ground except for the surroundings of the anchor members. Mortar or concrete is sprayed in a grid shape with the ground portion around the anchor member as an intersection, so that the greening base material is a grid made of mortar or concrete that is in close contact with the ground at the intersection portion. Since the side portion of the frame member is fixed so as to be pressed down on the ground surface, the collapse of the ground can be prevented and the protection can be stabilized.

In addition, since the greening base material is continuously formed without being divided into sections by grid-like mortar or concrete, the root system of the planted plant is stretched over a wide area on the ground surface. Can go around,
