DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for greening a retaining wall formed of artificial material such as a concrete retaining wall or a block pile.

[0002]

2. Description of the Related Art In general, there are the following retaining wall greening methods constructed by a concrete retaining wall, a block-laying method, or the like. That is, first, as shown in FIG. 5, vine plants B are planted below or on the top of the surface A of the structure, and are crawled on the surface A of the structure for their elongation and growth. Also, the second
As shown in FIG. 6, a planter P is installed on a surface A of a structure, and an appropriate shrub C is planted on the planter. The applicant of the present application filed a patent No. 1212
In the invention of No. 659, "the dressing bags are accommodated so as to be buried in the grooves provided at predetermined intervals on the glue slope, and wire meshes are stretched from above and planted at the storage position of the dressing bags. With the planting pipe facing downward from the horizontal and the base contacting the customer bag,
Mortar or concrete is sprayed on the wire mesh to form a sprayed layer so as not to block the tip hole of the planting pipe, and a portion of the guest clay bag in contact with the pipe base is cut open to spread the vine. We have provided a slope revegetation method using artificial materials to plant plants.

[0003]

However, among the conventional construction methods, a vine plant is planted at the lower end portion or the top end of the construction according to the first construction method in FIG. 5, and the surface of the construction is grown and grown by the vine. When the height of the structure is high, it takes a long time to plant greenery, and the planting space must always be secured at the lower end of the slope or at the top. A planter P is installed on the surface A of the structure according to the second construction method shown in FIG.
In the method of planting, there is a danger that the planter P may protrude toward the passage from the surface 1 and may hit during passage depending on the installation location. Furthermore, the invention of Japanese Patent No. 1212659 owned by the applicant of the present invention is suitable for excavated rocks such as soft rock, gravel and loam layers, but has a relatively small thickness of about 15 to 20 cm. It was limited to thin mortar and concrete spray.

[Specific example steps "drainage block stacking Engineering" general block masonry engineering drainage pipe is placed at the rate of 1 point to 2m ² ~4m ^2. In addition, in the present invention, FIGS. 2 and 3 show planting pipes 7 for each visitor bag when water is supplied from the ground.
And the planting pipe is set slightly downward from the horizontal. In this case, since rain does not enter from the downward planting pipe, a drainage pipe accompanying the greening method is not required. In FIG. 4, unlike the case of FIGS. 2 and 3, the supply of moisture cannot be expected from the ground. In order to incorporate rainfall into the planting pipe 7, the planting pipe is slightly shifted from the horizontal line. It is necessary to provide a drain pipe 9 in an upward direction and at the lower part of the customer bag 3 installed on the ground. "Retaining wall of block piler" Next, in the case of the retaining wall by the block piler, the concrete blocks are piled up, and the concrete body 50 is placed on the part separated from the slope and the gap part between the concrete blocks. Pour and fix concrete block and planting pipe. The above concrete

[0008]

According to the present invention having the above-described structure, the planting base is provided in the body of the ground and the structure. By increasing or decreasing the number of plants to be planted, a greening plan corresponding to the greening speed can be achieved. Also, there is a sense of security because the surface of the structure does not protrude. Subsequently, since the planting base is in the frame, drying of the planting base can be suppressed. Then
Since the shape-retaining net body is fixed to the cut-out portion of the sack with an anchor, the sack is placed in the groove, and then the concrete for forming the backing material layer or the retaining wall is formed. With the lapse of time until the casting, the upper soil in the bag is surely prevented from slipping downward to form a so-called downward swelling state. Furthermore, in the case where the planting pipe is installed upward or above the horizontal, it is possible to appropriately take in rainfall from the tip of the pipe. Moreover, the use of a water retention mat in the planting pipe has the effect of retaining rainfall and moisture from the ground.
