DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a greening structure on a slope, and more particularly, to a greening structure such as a mountain surface cut steeply or a slope forming a concrete retaining wall.

[0002]

2. Description of the Related Art Various structures have been developed for greening slopes such as steep mountain surfaces and concrete retaining walls. Slope greening structure can be broadly divided into two methods: spraying the soil containing adhering material, water-retaining material, seedlings, etc. onto the slope to adhere to it, and then breeding vegetation. There is a structure in which a hole for planting a plant is provided and the plant is bred here. In the structure for spraying the soil, a small stitch net is placed on the slope to prevent the soil from flowing due to rain, and the soil is sprayed on the net.
This structure has a disadvantage that the construction is troublesome and the construction cost is high. In addition, the construction of planting plants by drilling holes in the concrete retaining wall,
There is a drawback in that it takes time and effort to put the soil in the holes and plant the plants.

[0003] As a structure for solving such a drawback, a structure has been developed in which deciduous leaves are effectively used as humus, and plants are propagated in this humus (utility model registration No. 2556).
883). As shown in FIGS. 1 and 2, this greening structure has a two-layer structure of a main net 11 and an auxiliary net 12, and has a slope 10
It is stretched. A main net 11 having a large stitch is provided on the front side, and an auxiliary net 12 is provided between the lower surface of the main net and the slope 10. The auxiliary net 12 has a pocket 13 for storing fallen leaves 14 that have passed through the main net 11. For this reason, the auxiliary | assistant net 12 is being fixed to the slope 10 so that it may be folded back and a bag may be formed. This greening structure allows the leaves 14 to pass through the main net 11 and store them in the pockets 13 of the auxiliary net 12, where plants can be propagated as humus.

[0004]

The greening structure shown in FIG. 1 and FIG. 2 does not spray soil on steep slopes, and also does not allow soil or plants to enter holes in concrete retaining walls. Can breed. However, this greening structure requires two nets consisting of a main net and an auxiliary net to be stretched, and the auxiliary net is stretched with a unique structure that can be folded back to form a pocket, which makes the construction extremely labor-intensive. However, there is a drawback. Working on steep slopes is dangerous. For this reason, it is important that the work can be performed as simply and efficiently as possible in a short time. Furthermore, this greening structure uses a two-layer net material, and furthermore, the auxiliary net is folded back and stretched, so that it is necessary to use a net material having an extremely large area, and the material cost is high. . In particular, in order to accumulate a large amount of litter and increase mulch, it is necessary to fold the auxiliary net, in other words, to lengthen the wrap, so it is necessary to use an auxiliary net with a larger area. There is a disadvantage that the cost increases.

[0005] The present invention has been developed for the purpose of solving such a drawback. An important object of the present invention is to provide a simple, easy, and efficient construction method that can efficiently and quickly reduce the material cost, thereby significantly reducing the construction cost and effectively greening steep slopes. It is to provide a greening structure.

[0006]

The slope greening structure of the present invention is an improvement of the greening structure in which the net 1 is stretched on the slope 10 to green the slope. Greening structure of the slope, net 1
It is fixed away from the slope 10 via the spacer 2. This net 1 has a large-leaf leaf passing portion 3 having a large stitch at an upper portion and a small-leaf preventing portion 4 having a small stitch at a lower portion, and a lower end portion of the net 1 is provided so that leaves accumulated on the leaf-fall preventing portion 4 do not leak. The space between the slope 10 is closed. The greening structure of the slope is such that the leaves fall through the leaf passing portion 3 of the net 1 so that the leaves fall between the net 1 and the slope 10, and the leaves that fall between the net 1 and the slope 10 are prevented from falling by the leaf fall preventing portion. The humus is deposited between the slope 4 and the slope 10 to produce humus, and plants are vegetated on the humus.

The greening structure on the slope of the present invention is preferably
The water retaining fabric 5 is fixed between the net 1 and the slope 10 along the lower end of the leaf fall preventing portion 4 of the net 1, and the lower end of the leaf fall preventing portion 4 is closed by the water retaining fabric 5 to prevent the fall of leaves. Prevent leaks.
The water retaining fabric 5 preferably contains a fiber material, a fertilizer, and a water retaining material.

Further, the greening structure of the slope of the present invention is preferably such that the stitch of the leaf-falling portion 3 is 10 cm to 1 m, the stitch of the leaf-fall preventing portion 4 is 1 to 10 cm, and the distance between the net 1 and the slope 10. Is 5 to 50 cm. In addition, net 1
Can be fixed to the slope 10 with the anchor 6.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. However, the following examples illustrate the greening structure of the slope for embodying the technical idea of the present invention, and the present invention does not specify the greening structure as follows.

Further, in this specification, in order to make it easier to understand the claims, the numbers corresponding to the members shown in the embodiments will be referred to as “claims” and “ In the column of “means”. However, the members described in the claims are not limited to the members of the embodiments.

In the greening structure shown in FIG. 3, a net 1 is stretched on a slope 10 via a spacer 2. Spacer 2
Secures the net 1 away from the slope 10. The illustrated greening structure uses an anchor 6 for the spacer 2 that secures the net 1 away from the slope 10. As shown in FIG. 4, the anchor 6 is fixed by driving its tip into the slope 10 or by burying it in a concrete retaining wall. The anchor 6 shown in FIG. 4 has a male screw at the rear end. Male thread 6A
Are fixed by screwing two nuts 7 to sandwich a fixing plate 8. This fixing plate 8 has a U bolt 9
Is inserted, and the wire 1A of the net 1 is fixed by the U bolt 9. This structure secures the net 1 to the anchor 6 and connects the net 1 in place for a long time. However, although not shown, the wire of the net can be directly connected to the anchor via a U-bolt. Further, the greening structure of the present invention can fix the net to the slope using all the spacers that can fix the net to the slope without specifying the spacer that fixes the net away from the slope as an anchor.

The distance between the net 1 and the slope 10 is 5 to 50.
cm, preferably 10 to 40 cm, more preferably 1 cm
It is fixed to be 0 to 30 cm. When this interval is reduced, the amount of leaves stored between the net 1 and the slope 10 decreases. Conversely, if it is too wide, the amount of fallen leaves stored is too large, and the net 1 cannot withstand the weight of the mulch, and the large area of the slope 10 cannot be greened in a short period of time.
This is because it takes time for the fallen leaves to deposit vertically. Therefore, the distance between the net 1 and the slope 10 is ideally about 20 cm.

The net 1 has a leaf-falling portion 3 having a large stitch at the upper portion and a leaf-fall preventing portion 4 having a small stitch at the lower portion. The lower end of the net 1 is closed so that the fallen leaves deposited on the fallen leaf preventing portion 4 do not leak. The defoliation passing part 3 of the net 1
The stitch is 10 cm to 1 m, preferably 10 to 50 cm, more preferably 10 to 20 cm. If the stitch of the fallen leaves passing section 3 is smaller than 10 cm, it will not be possible to smoothly pass through the fallen leaves. On the other hand, if the stitches are too large, the entire slope 10 cannot be greened without gaps in a state where plants such as ivy grow. For this reason, the stitch of the fallen leaf passage section 3 is optimally about 15 cm. The stitch of the leaf fall prevention part 4 is 1-10c
m, preferably 2 to 8 cm, more preferably 3 to 5 c
m. If the gap between the leaf fall preventing portions 4 is small, the amount of wire used to manufacture the net 1 increases and the cost increases. Conversely, if it is increased, the leaves will fall and will not be stored. Therefore, the stitch of the leaf fall prevention part 4 is optimally about 5 cm square.

The net 1 having this structure is fixed to the slope 10 as shown in FIG. As shown in FIG. 5, the high slope 10 connects the net 1 with the leaf-falling portion 3 and the leaf-fall preventing portion 4 to
Fix it in multiple rows vertically.

The net 1 closes the slope 10 at the lower edge of the leaf-fall preventing part 4 to provide a space between the leaf-fall preventing part 4 and the slope 10 for depositing leaves. In the tree planting apparatus shown in the figure, a water retention layer 5 is fixed between the net 1 and the slope 10 along the lower end of the leaf fall preventing portion 4 to close the lower edge of the leaf fall preventing portion 4. The water retaining fabric 5 is a tubular mesh bag obtained by adding a slow-acting fertilizer to a fibrous material such as coconut fiber, peat moss, moss, wood chips, quartzite, or a water retaining material. The water retention material 5 can also add plant seeds. Furthermore, seedlings can be planted in the water retention medium 5. Water retention area 5 where seeds are added and seedlings are planted,
There is a feature that a specific plant can be grown quickly by germinating the seeds added or growing seedlings. In addition, since water is retained here, there is a feature that plants can be grown quickly even in an environment where the amount of rainfall is small.

The lower edge of the leaf-fall preventing portion of the net is fixed to the slope without any gap without using a water retention layer, so that the lower edge is closed to prevent the leaf from leaking. You can also. Further, it is also possible to fix a part of the leaf fall prevention part directly to the slope and fix a water retention material to the other part to close the lower end of the leaf fall prevention part. Furthermore, the water retention medium can be fixed not only to the lower end edge of the leaf fall prevention part but also to the upper end edge of the leaf fall passage part.

The greening structure having the above structure allows the leaves to fall between the net 1 and the slope 10 by passing through the leaves 1 of the net 1. The fallen leaves fall down along the surface of the slope 10 and accumulate between the fallen leaf passage portion 3 and the slope 10. Since the fallen leaves that accumulate in the fallen leaf passage portion 3 do not leak from the net 1, a large amount of the fallen leaves accumulates gradually and becomes mulch. In the mulch, the flying seeds germinate and grow. Further, the water retention medium 5 to which the seeds are added is supplied with water, and the seeds germinate to grow the plants. Plants that grow from the water retention medium 5 can be grown quickly by using the mulch deposited on the water retention medium 5 as a fertilizer or by the fertilizer added to the water retention medium 5. For this reason, the slope 10 on which the net 1 with a unique structure is stretched,
While effectively utilizing the deciduous leaves as mulch, various plants can be bred on the slope 10 and greened to a beautiful natural state.

[0018]

The greening structure of the slope according to the present invention is characterized in that it can be simply, easily, and quickly and efficiently constructed, and that the material cost and the construction cost can be reduced and the steep slope can be effectively greened. There is. That is, the greening structure of the slope of the present invention fixes the net away from the slope via a spacer, and the net has a large-leaf-leaf passage portion at the top and a small-leaf-prevention portion at the bottom at a small stitch. In addition, the lower end of the net is closed between the slope and the slope so that the fallen leaves that accumulate on the fallen leaf prevention part do not leak. This is because the fallen leaves are deposited between the fall prevention part and the slope to form humus, and plants are vegetated on the humus.

The revegetation structure of the slope of the present invention makes it possible to effectively use deciduous leaves as humus by using a net having a unique structure having a large-leaf-leaf-passing portion at the top and a small-leaf-prevention portion at the lower stitch. While using, various vegetation can be propagated on the slope to make it ideally green. Furthermore, since the greening structure of the present invention does not require the use of a net having a large area as in the related art, it is possible to reduce the material cost and also to simplify the construction of the net to reduce the construction cost. . Furthermore, the greening structure of the present invention, which can simplify construction, works safely and quickly even on steep slopes,
The feature of greening steep slopes effectively is also realized.
