DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope revegetation device, and more particularly to a cut rock slope, a concrete spray slope,
The present invention relates to a slope greening apparatus suitable for applying to a firm slope such as a slope.

[0002]

2. Description of the Related Art Conventionally, when greening a slope, a thin layer spraying method such as a seed spraying method or a spraying method of a soil material,
A thick-layer base material spraying method in which soil, seeds, compost, fertilizer, additives and the like were mixed was performed. Moreover, when planting a tree, in order to increase the thickness, a thick-layer base material spraying method or the like is performed on the basis of earth and sand mixed with fibers.

[0003]

However, in the conventional greening method for rock cutting slopes, western grass is used as a herb, and wood is limited to fertilizer trees such as a goat. There is a problem that it takes a long time for vegetation to be selected and latent natural vegetation to be introduced and grown. Also,
Although the binder is mixed in the sprayed thick base material, the base material is exposed on the slope, so the base material collapses due to strong wind and rain until the herbs and trees grow, Greening sometimes became incomplete.

[0004] An object of the present invention is to solve such problems, and a slope revegetation apparatus capable of surely revegetation in a short period of time even on a solid slope such as cut rock mass. Is to provide.

[0005]

SUMMARY OF THE INVENTION The present invention is a slope greening apparatus, and is configured as follows to solve the above-mentioned technical problem. That is, the present invention relates to a slope greening device for planting greenery by planting herbs and trees on the slope, comprising: a flat bag formed of a net and having an opening at an end; A biodegradable mat attached to the, a greening base material filled in the bag body, and fixing means for fixing the bag body to the slope, the mat on the upper surface side of the bag body, The method is characterized in that herbaceous seeds are affixed, and the tree seedlings are planted.

[0006] This slope greening device can fill a bag with a greening base material, grow grass and woody plants in advance, and install them on the slope to achieve greening in a short period of time. The slope may be a cut rock slope, a concrete spray slope or a slope. In this case, a solid cut rock mass, a concrete sprayed slope, a sloped surface, etc., which were conventionally difficult, can be reliably greened in a short period of time.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an apparatus for greening a slope according to the present invention.

FIG. 1 shows a slope greening apparatus 1 according to the present invention. The slope greening device 1 is for greening the slope 10 with herbs 11 and trees 12, and is a flat bag formed of a net having an appropriate mesh width and having an opening 13 at an end. 14, a biodegradable seed mat 15 a and biodegradable mats 15 b and 15 c attached to the inside of the bag body 14, and fixing means 16 for fixing the bag body 14 to the slope 10. . The mat 15a on the upper surface side
The seeds 17 (FIG. 2) of the herb 11 are attached as described later. The inside of the bag 14 is filled with a greening base material 18. Reference numeral 19 in the drawing is a joint belt.

The bag 14 is formed of, for example, a geonet having a mesh width of about 6 to 8 mm. Seed mat 15
The a and the mats 15b and 15c are made of natural fiber or a biodegradable polymer resin as a raw material. For example, a BG mat (trade name) manufactured by Tosco Corporation can be used. For example, a ring can be used as the fixing means 16, and the bag body 14 can be reliably fixed by fixing the ring to the slope 10 with an anchor (not shown).

As shown in FIG. 2, the seeds 17 of the herb 11 are previously applied to the entire surface of the seed mat 15a attached to the inside of the upper surface of the bag body 10. The seed 17 has a low stem and shallow root, and a mixture of herbaceous seeds in a nitrogen-fixed form, for example, white clover, red clover, and medhagi can be used.

The procedure for manufacturing and constructing the planting apparatus 1 will now be described. First, as shown in FIG. 3A, the inside of the bag body 14 is filled with a greening base material 18. The type of the greening base material 18 is a material that does not fall out from the gap of the net having a mesh size of 6 to 8 mm of the bag body 14 and has both physical properties and physicochemical properties required as soil. , Wood chips, sludge cakes and their firing materials, rocks, cement or polymer binders, slow-release fertilizers, etc. according to the local situation. As a filling method, a spraying method and a charging method can be used. On the front side of the bag 14, that is, on the side to which the seed mat 15a is attached, a cross-shaped cut 19 of an appropriate size is provided.

Next, as shown in FIG.
Kimoto 1 from the cross-shaped cut 19 provided on the front side of
Plant 2 pot seedlings. Thereby, the greening apparatus 1 is completed. Then, as shown in FIG.
Is cured for an appropriate period, so that the herb 11 germinates and grows from the seed mat 15a, and the tree 12 of the pot seedling is established.

At this stage, as shown in FIG. 1D, the greening apparatus 1 is installed on the slope 10. Although the installation work is basically performed using a crane or the like, the bag body 14 can be installed manually by reducing the size of the bag body 14. Bag 1
The fixing of 4 is performed by disposing the opening 13 at a predetermined position with the opening 13 facing upward, and fixing the rings 16 at the four corners of the bag body 14 to the slope 10 with anchors (not shown).

As described above, the slope revegetation apparatus 1 according to the present invention fills the pouch 14 with the revegetation base material 18, grows the herbaceous plants 11 and the woody plants 12 in advance, and installs them on the slopes 10. Therefore, the slope 10 can be greened in a short time. In addition, since the greening base material 18 is filled in the bag body 14, it is possible to prevent the greening base material 18 from flowing out even when strong wind and rain is blown, and to plant the herbs 11 and the woody plants 12 reliably. be able to.

At the beginning of installation, the introduced woody tree 12 is pressured by the invading species due to the effect of mulching by the seed mat 15a and the symbiosis with the artificially introduced low stem and shallow rooted herbaceous plants 11. Without growing up. Furthermore, since the greening is completed only by installing and fixing the existing greening apparatus 1 on the slope 10, the construction work of the fiber-mixed earth and sand and the spraying of the thick-layer base material to introduce the woody system as in the related art are performed. Can be saved twice,
There is no need to select the time of construction. In addition, solid cut rock, concrete sprayed slopes, slopes, etc., which have been difficult in the past, can be reliably greened in a short period of time.

[0016]

As described above, according to the slope greening apparatus of the present invention, the greenery base material is filled in the bag and the herbaceous and woody plants are grown in advance. By doing so, it can be greened in a short time. In addition, it can be securely attached to a solid cut rock mass, a concrete sprayed slope surface, a slope frame surface, and the like, which have been difficult in the past, and can be greened.
