[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope greening method.

[0002]

2. Description of the Related Art One of the methods for greening a naturally collapsed mountain skin, a thin mountain skin, or a mountain skin scraped off for road construction is to stretch a net on a slope to form a net. Reinforcing bars are installed in a grid, and mortar or concrete is sprayed on the bar-shaped reinforcing bars to form a grid-like swollen body, while plant seeds such as grass are for example organic compost, chemical fertilizer, plant There is a method of spraying a vegetation base material mixed with a conductive fiber, a water retention agent, a soil improvement material, and the like on a slope in a lattice-shaped frame surrounded by the above-mentioned swelling body.

[0003]

According to such a slope greening method, the grid-like swelling body prevents the vegetation base material from running off due to rainfall, thereby greening the slope. Is preferably achieved, but there is room for improvement in that the lattice-shaped swelling body, which is an artificial structure, is conspicuous even in the distance and deteriorates the natural scenery.

[0004] In the above-mentioned slope revegetation, it is preferable to make the slope a forest in order to achieve harmony with the surrounding landscape of the slope, permanent stabilization of the slope, and restoration to the natural world. For this reason, the introduction of trees to transplant tree seedlings and seedlings to the slopes may be implemented at the same time, but in order to make the rooting of the tree seedlings easier, it is necessary to dig deep labor. However, the digging work and the work of storing the vegetation base material in the hole are limited before the installation of the mesh, and the work procedure becomes complicated. is there.

[0005]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a method of three-dimensionally greening a slope to make a grid-like bulging body inconspicuous. It provides a greening method that can be easily achieved.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS That is, in the present invention, when greening a slope, first, a net is stretched on the slope, and a reinforcing bar is placed on the net in a grid pattern. Mortar or concrete is sprayed on the reinforcing bar to form a grid-shaped bulge, while the rectangular shape is along the grid-shaped horizontal frame of the bulge
, And on the left and right sides of the mesh shelf
The lower edge is formed from a triangular net-like shelf along the slope
It is to form a accommodating area of vegetation substrate and, piercing the slopes

By piercing the anchor into the slope, the anchor is raised and installed in a lattice-shaped frame formed by the swollen body, and the vegetation including plant seeds is provided in the seedling fence and the lattice-shaped frame formed by the swollen body, respectively. The method of spraying the base material will be adopted.

According to such a slope greening method, the plant seeds contained in the vegetation base material germinate and grow in the lattice-shaped frame formed by the swollen bodies and within the seedling fence. The seeds germinate and grow from the rising surface of the nursery fence with a number of openings installed in the lattice frame of the plant. When the slope is viewed from directly below the slope, the grid-like horizontal frame formed by the swollen body is covered by the three-dimensionally germinated and grown plants, and the appearance of the slope is improved. Is good in view.

[0008] In this case, it is preferable that, in addition to the fences for raising the seedlings, the fences for raising the seedlings are arranged along the vertical frame of the grid, in addition to the fact that the foster seedlings fence the lattice-like horizontal frame.
The growing plant is located on the side of the prominent bulge so as to cover the bulge as much as possible. The swollen body can be made inconspicuous even from a distance, and harmony with the surrounding landscape of the slope can be suitably achieved.

On the other hand, the vegetation base material accommodated in the nursery fence is used as the soil for the slope, and tree seedlings are planted as necessary, thereby eliminating any difficult digging work which is restricted by the work procedure. In this way, tree planting on the slope can be suitably achieved. Alternatively, if a vine plant seedling is planted, the vine plant grows entangled with the swollen body, and the vine plant directly covers the swollen body itself. Is better.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A slope greening method according to the present invention will be described below with reference to the drawings. First, as shown in FIGS.
A mesh 1 such as a synthetic resin net, a metal lath wire net, or a net is stretched on the slope 2 and a short auxiliary anchor 3 is cast to fix the mesh 1.

One or more (two in the illustrated example, two upper and lower bars) rebars 4 are arranged on the mesh body 1 in a grid pattern, and the rebars 4 are connected to the long main anchor 5. Mortar or concrete is sprayed on the reinforcing bar 4 so as to form the grid-shaped bulging body 6. At this time, a curing sheet 7 is laid to prevent the mesh body 1 surrounded by the bulging body 6 from being filled with mortar or concrete.

Next, a seedling raising fence 8 prepared in advance is set up and installed above the swollen body 6 along the lattice-shaped horizontal frame. This nursery fence 8 is, as shown in FIG.
Numerous openings (in the illustrated example, the shape is rectangular, but the shape such as a rhombus does not matter, and the point is that the size should be such that a vegetation base material 9 described later does not easily fall.) It is formed by folding a wire net having the above, but it can be changed to a synthetic resin net having a large number of openings.

Specifically, the seedling raising fence 8 has a rectangular mesh fence portion 8a along the lattice-like horizontal frame of the swollen body 6, and a lower edge formed by being continuously provided on both left and right sides of the mesh fence portion 8a. Consists of triangular mesh fence portions 8b, 8b along the slope 2, and
An anchor 8c for piercing and fixing the slope 2 is provided.

Returning to FIGS. 1 and 2, the curing sheet 7 is peeled off, and a space defined by the seedling raising fence 8 and a lattice-shaped frame surrounded by the swelling body 6 are filled with, for example, organic compost. And plant fertilizers, plant fibers, water retention agents, soil amendments, etc., and spraying a vegetation base material 9 in which plant seeds are mixed, and if necessary, a tree seedling b And plant seedlings c and vine plants.

The plant seeds contained in the vegetation base material 9 include Kentucky fescue, highland bentgrass, and the like.
At least one species such as exotic grass species such as bermudagrass and red top, plant species such as cosmos, gypsophila, oakweed, and dianthus, and tree species such as yamahagi, weasel, and komatsunagi are appropriately selected.

According to such a slope greening method, the vegetation base material 9 is prevented from flowing out due to rainfall by the lattice-shaped swelling body 6 and, as shown in FIG. In addition to the plant seeds contained in the timber 9 germinating and growing in the lattice frame of the swollen body 6 and the seedling fence 8, a large number of openings provided in the lattice frame of the swollen body 6 The plant seeds also germinate and grow from the rising surface of the nursery fence 8 having a.

As described above, when the plant seeds germinate and grow three-dimensionally from the seedling raising fence 8 above the lattice-shaped horizontal frame of the swollen body 6, the slope 2 is viewed from directly below the slope. ,
The grid-like horizontal frame formed by the swollen body 6 is covered by the three-dimensionally germinated and grown plants, and furthermore, the grown plants are covered by the horizontal frames, so that the appearance of the slope 2 has a scenic appearance. To be good.

If necessary, the vegetation base material 9 accommodated in the seedling raising fence 8 is used as the soil for the slope 2 and tree seedlings b such as Kodemari, Tani-Utsugi, Avelia, Yamabuki and Hydrangea are planted here. The introduction of trees for the purpose of harmony with the surrounding landscape of the slope, permanent stabilization of the slope, and restoration to the natural world will be achieved in the future.

Alternatively or additionally, by planting a vine plant seedling c such as Kizuta, Natsuta, Hedera helix, Yamagrape, etc., the vine plant grows so as to be entangled with the swollen body 6, Since the vine plants directly cover the swollen body 6 itself, the landscape appearance of the slope 2 is further improved. Alternatively, instead of or in addition to tree seedlings and vine plant seedlings, plant flower bulbs and seedlings such as tulips, narcissus, primroses, lilies, and shibazakura to plant beautiful flower-looking slopes. 2 greening is achieved.

As shown in FIG. 5, in this embodiment, a quadrangular seedling of a coma deli c is planted on a nursery fence 8 in a certain frame A by a swelling body 6 and a frame B on the right side of the frame A is planted. Is planted on the seedling raising fence 8 in the shape of a rhododendron d showing a rhombus, and a seedling of avelia e shown in a circle is planted on the seedling raising fence 8 in a frame C adjacent to the right of the frame B, and in a frame D adjacent to the right of the frame C. Seedlings of Yamabuki f shown in an elliptical shape and seedlings of Hetera helix i shown in white small circles and Hetera helix i shown in black small circles are planted as appropriate on the nursery fence 8 of the seedling. Is planted.

Here, when the vegetation base material 9 contains, for example, two kinds of plant seeds, herbaceous and woody, if a grass species is selected as the herbaceous species, it is difficult to receive pressure from the pasture, for example, Yamahagi and Itachihagi. It is desirable to select a tree seed such as Komatsunagi and spray it on the nursery fence 8. If a tree seed such as yashabushi, Yamanoki, Akamatsu, etc., which is easily subjected to pressure by grass, is selected, cosmos or gypsophila can be used. It should be noted that it is desirable to include in the vegetation base material 9 a small amount of grass species such as pheasant daisies and nadesico, and grass species having relatively low plant height such as creeping red fescue and highland bentgrass.

In the above-described embodiment, the seedling raising fence 8 is installed along the upper part of the lattice-shaped horizontal frame of the swollen body 6, but as shown in FIG. The nursery fence 8 may be installed along the side, or may be installed in the middle part of the upper and lower horizontal frames, or these may be combined.

More preferably, as shown in FIG. 7, a nursery fence 8 is installed along the lattice-shaped vertical frame of the swollen body 6, and plants that germinate and grow three-dimensionally on the nursery fence 8 are provided. This is to wrap around the swollen body 6 and cover the grid-shaped swollen body 6 as much as possible with plants. According to such a greening method, the grid-shaped swollen body 6 can be seen from a distance. It can be made to stand, and the harmony with the surrounding scenery of the slope 2 is more suitably achieved.

[0026]

The slope revegetation method according to the present invention is implemented in the form as described above. A seedling fence is installed in a lattice-shaped frame made of swollen bodies, and plant seeds are planted. By germinating and growing three-dimensionally, and by covering the artificial structure made of mortar or concrete with this plant, the appearance of the slope can be made to be aesthetically pleasing, and Harmony is preferably achieved.

In particular, if tree seedlings are planted on the vegetation base material in the nursery fence, it is not necessary to perform any difficult digging work which is restricted by the work procedure, and the future greening which makes the slopes into a forest is suitable. Achieved. By planting the vine plants, the vines grow in a manner that they are entangled with the swelling body, and the swelling body itself is directly covered by the vine plants, thereby improving the appearance of the slope. It will be even better.

Alternatively, when planting flower seedlings, slope greening can be achieved, which makes the appearance of flowers colorful, and the whole is artificially constructed by introducing a nursery fence that greens the slope three-dimensionally. In addition to being able to make the appearance of the slope good in view of the landscape by making the swollen body of the object inconspicuous, the future forestation of the slope can be easily achieved.
