TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a greening method for growing a plant on a laying surface to achieve greening.
[0002]
[Prior art]
There is a mortar spraying method as a slope stabilization method, but it is not possible to vegetate on the sprayed layer, and there is a problem that the sprayed layer becomes tattered and deteriorated when the aging is further aged.
BACKGROUND ART Conventionally, a revegetation method is known in which vegetation is planted or planted on a vegetation base layer constructed by spraying a vegetation base material for the purpose of collapse of a slope such as a road slope and vegetation greening.
For the purpose of maintaining road environment, securing road surface drainage, and removing line of sight obstacles for vehicles, it is necessary to periodically mow the green area of the slope of the road and the shoulder of the roadside in a band-like area, which requires a large amount of labor and costs. There is a problem of high.
[0003]
[Problems to be solved by the present invention]
With conventional greening technology, it was difficult to take measures against weeds while greening.
[0004]
The present invention has been made to solve the above-described conventional problems, and an object of the present invention is to provide a greening method capable of taking measures against weeds while greening.
[0005]
[Means for Solving the Problems]
In order to achieve the object as described above, the present invention provides a bag containing fertilizer on a laying surface, and a covering material obtained by mixing a chip piece obtained by cutting conifer bark and a consolidated material into a bag. Is sprayed on the entire surface of the bag, and plants are vegetated in the bag body. Further, the present invention is the above-described greening method, wherein the bags are provided in a multi-stage manner at a predetermined interval.
Further, the present invention is the above-mentioned greening method, wherein the bag body has a hitting portion formed in a longitudinal direction.
[0006]
[Embodiment of the present invention]
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0007]
First, a basic substrate to be used will be described.
According to the present invention, a bag to be installed on a laying surface and a covering material sprayed on the entire laying surface are basic substrates.
[0008]
<B> Bag body The bag body 1 is a member that accommodates the vegetation base material 12 therein and functions as a vegetation base.
[0009]
The bag 1 is formed in a tubular shape whose length is at least twice the size of the mouth. The bag body 1 has a punching portion 11 formed in a part thereof in the longitudinal direction and on the same line. The hitting portion 11 may be continuous or intermittent as long as it is on the same line. The length of the bag 1 is appropriately selected according to the greening range. The striking portion 11 functions as a striking when fixing the bag 1 to an installation surface with an anchor or the like.
[0010]
The bag body 1 is formed into a perforated structure using a known material exhibiting appropriate flexibility and strength so as to ensure air permeability and water permeability. The bag body 1 is formed by weaving into a planar shape or by perforating a planar non-porous material as appropriate to form a perforated structure.
[0011]
The vegetation base material 12 accommodated in the bag 1 is formed by mixing generally used mountain sand, soil improvement material, slow-release fertilizer, and the like.
[0012]
<B> Coating material The coating material 2 is a member that covers the entire laying surface on which the bag body 1 is installed.
The coating material 2 is made of a solidified material such as a chip piece 22, mountain sand, and cement.
[0013]
As the chip piece 22, a bark cut into a bark shape is used. As the bark to be used, it is preferable to use bark of conifers, especially cedar and cypress. Since the bark of cedar and cypress contains a large amount of organic substances having an antibacterial action, they do not rot for a long period of time and form appropriate voids in the coating material 2 after spraying, thereby making the sprayed surface water-permeable and water-retentive. Can be improved.
Furthermore, since the chip piece 22 is cut into a bark shape and has a fibrous shape, it is possible to prevent the occurrence of cracks on the sprayed surface of the coating material 2 by exhibiting a binder effect. In addition, these barks have become a problem as industrial waste in recent years, but recycling them can contribute to solving the problem of bark disposal.
[0014]
Next, the construction procedure of the greening method of the present invention will be described.
The present invention sets a bag containing fertilizer on the laying surface, and sprays a coating material obtained by mixing a chip piece obtained by cutting the bark of a conifer and a consolidation material onto the entire surface on which the bag is placed, This is a greening method in which plants are vegetated in bags. Hereinafter, each step will be described separately.
[0015]
<B> Installation of the bag on the laying surface Materials such as the bag 1, the covering material 2, and the plant 4 used for construction are carried into the site.
Clean laying surfaces such as slopes for greening.
[0016]
As shown in FIG. 2, the bag bodies 1 are arranged in a multi-stage manner on a laying surface at a constant interval.
The laying form of the bag 1 is not limited to this example, and can be appropriately selected according to the greening form.
The installed bag 1 also functions as a water stop when raining.
[0017]
The bag 1 installed on the laying surface is fixed. The bag 1 is fixed by driving an anchor 3 or a concrete nail into the margin of the bag 1. The bag 1 is fixed in a state of being hung on the laying surface.
The vegetation contained in the bag 1 is fixed to the bag 1 by using a margin, so that an anchor or the like is pierced by penetrating a portion of the bag 1 containing mountain sand or the like. The outflow of the base material 12 and the damage of the bag 1 itself can be prevented.
[0018]
<B> The coating material 2 is sprayed until the surface for laying the coating material and the entire surface of the installed bag body 1 are covered.
The coating material 2 is stirred by a stirring hopper and sprayed using a compressor.
The chip pieces 22 included in the coating material 2 form appropriate voids in the sprayed soil to ensure water permeability, and the chip pieces 22 absorb water to improve water retention. As a result, curing of the sprayed layer can be prevented.
Further, the fibrous material of the chip piece 22 acts as a flexible reinforcing material, and the sprayed layer becomes flexible, and the toughness against vibrations such as walking and earthquakes is improved, so that generation of a crank can be prevented. Furthermore, even if a part of the sprayed layer is damaged, it is possible to prevent the damage range from expanding and prevent the base from collapsing.
After the spraying of the coating material 2 is completed, the consolidated material contained in the coating material 2 is cured for about two days.
[0019]
<C> A planting hole 21 for introducing the plant 4 is formed in a protruding portion covering the bag 1 in the sprayed layer of the covering material 2 having completed plant planting and curing. The planting holes 21 are set at a depth such that they penetrate the covering material 2 covering the bag 1 and the upper surface of the bag 1 at predetermined intervals. The planting hole 21 is formed using an anchor, an electric drill, or the like.
The planting hole 21 also functions as a water inlet for rainwater or the like.
The plant 4 is introduced into the planting hole 21. As the plant 4 to be introduced, ground cover such as Rishimakia / Hatsuyukikazura / Matsubagiku is suitable. The introduction of plants is preferably 4 plants / m ² .
[0020]
<D> Completed greening The bag 1 containing the soil improving material and the slow-release fertilizer allows sufficient supply of nutrients to the plant 4 even on a poorly laid surface.
The hardening of the caking material contained in the covering material 2 can prevent the germination of flying plants.
For this reason, maintenance-free, which eliminates the need for mowing weeds, is achieved, and the landscape at the beginning of construction can be provided for a long period of time with minimal landscape management labor.
In addition, the vegetation portion and the non-vegetation portion can be freely configured, and a visually pleasing greening pattern can be provided.
The construction range may be the entire slope or a part of the slope such as the slope side or the slope side of the slope.
[0021]
[Effects of the present invention]
Since the present invention has been described above, it is possible to take measures against weeds while greening the slope.
