DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vegetation bag used for revegetation, for example, on a slope of a hillside or a river embankment, or on a slope formed with land reclamation.

[0002]

2. Description of the Related Art Conventionally, for the above-mentioned greening for protecting the slope and maintaining the landscape, for example, vegetative seeds, fertilizers and the like are mixed with local soil and filled into vegetation bags, and this so-called sandbag is attached to the slope. The greening method was installed in

[0003]

However, most of the soil in the field contains large blocks of stones, so that the sandbags become heavy and the workability is poor, and the soil is hung inside the bag. Even if a thread is provided to forcibly restrict the bulge of the bag, it is difficult to handle the soil because the soil is biased to the lower side of the vegetation bag and the vegetation bag swells. In addition to hindering the construction, the vegetation bags tend to rise and become less familiar with the slopes, and there is a problem in that the workability is generally poor.

[0004] In addition, the local soil is not always suitable for growing vegetative seeds, and as described above, it is often rather thin due to the inclusion of large stone lumps. However, there is a problem that even if germinated, it is difficult to take root and easily die.

Further, if the weight of the vegetation bag is increased in order to improve the germination of the vegetation seeds mixed with the local soil, the soil filled in the vegetation bag is spilled more, and the weight is reduced. On the contrary, there was a problem in that the germination became poor. In addition, for this reason, there was a problem that a thick-bud bulb could not be selected as a vegetation base to be mixed with the local soil.

The present invention has been made in view of such circumstances, and has excellent workability and workability. In addition, the slope is constructed to have a uniform thickness and the vegetation base is used. It is an object of the present invention to provide a vegetation bag in which germination and growth of vegetation seeds and bulbs, as well as grass and bamboo runners, can be performed satisfactorily.

[0007]

The vegetation bag according to the present invention which has attained the above-mentioned object at least partially degrades an artificial soil material obtained by mixing a vegetation base with a vegetation material. While filling the bag of the tubular sheet to form the artificial soil bag, at least the front and back two net-like meshes whose surface side is suitable for germination and growth of the vegetation base are placed on both sides in the width direction and in the vertical direction. Side to form a mesh bag, further connect the two front and back nets in the width direction at predetermined intervals in the vertical direction with a hanging thread, divide the inside of the mesh bag into a plurality of compartments, It is characterized in that the artificial sack is inserted into each compartment.

As the vegetation material, for example, one or more kinds of soil improver, general chemical fertilizer, other organic materials such as bark compost and peat moss, and inorganic materials such as vermiculite and partite are selected. One or more vegetation seeds, bulbs, lawn or bamboo runners are selected.

[0009] As the bag of the tubular sheet, in addition to the one that partially decomposes with time, one that decomposes the whole bag with time is used. As the mesh of the net-like bag, corrosiveness, corrosion resistance, and corrosion control fiber are used. Are used.

[0010]

According to the bag for vegetation of the present invention constructed as described above, since the artificial soil material is filled in the bag of the tubular sheet, the artificial soil material spills out and is biased in the bag. Furthermore, since the runoff is effectively prevented, and the entire vegetation bag including the artificial clay bag is highly flexible, the vegetation bag fits well on the slope and the slope is vegetated. A uniform thickness is applied by the bag.

In addition, the artificial soil material contributes to the weight reduction of the vegetation bag and the growth of the vegetation base, and the tubular sheet bag is at least partially decomposed, so that the artificial soil material is reduced. Good adherence to the slope and, in turn, the rooting of the plant is enhanced, and even if a bulb with a large bud is selected as a vegetation base, it can be passed through well, and the workability and workability are good. Thus, the greening of the slope is effectively achieved.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show a vegetation bag M according to an embodiment of the present invention.
This vegetation bag M is formed by dividing the inside of the mesh bag 1 into a plurality of compartments a, and inserting a flexible rod-shaped artificial soil bag 2 into each compartment a.

More specifically, the artificial guest bag 2 is
One or more vegetation materials such as soil conditioners, general chemical fertilizers, organic materials such as bark compost and peat moss, and inorganic materials such as vermiculite and partite, as well as vegetation seeds, bulbs, lawns and bamboo runners as vegetation bases The artificial soil material 3 is filled in a tubular sheet bag 4 which is at least partially degraded with time, and the mouth of the bag 4 is closed by, for example, bonding.

Here, an example of the sheet material of the bag 4 will be described with reference to FIG. 3. This sheet material is, for example, 30 to 50% of pulp fiber and 35% of polypropylene fiber.
On one side of the water-soluble sheet 5 composed of about 45% and about 10% to 30% of powdery or fibrous polyvinyl alcohol, suitable for germination of vegetation base contained in the artificial soil material 3 described above. (For example, consisting of ten warps 6 of vinylon 30th count and weft threads 7 of 6 pieces / inch). When the water-soluble sheet 5 is manufactured by Sukiage, The kaya material 8 is joined and integrated with the water-soluble sheet 5 by polyvinyl alcohol, which is a constituent material of the water-soluble sheet 5.

By taking this joining means and dissolving only the water-soluble sheet 5 with time, the tubular sheet bag 4 has a property of partial decomposition with time. The composition of the water-soluble sheet 5 is not limited to the above ratio, and most preferably, a softwood pulp fiber is used, and a polypropylene fiber is 2%.
A denier thickness of 5 mm is used. As polyvinyl alcohol, a fiber of 1 denier thickness of 3 mm is used. 35 to 45% of these pulp fibers, 35 to 45% of polypropylene fibers, and polyvinyl alcohol are used. 20
By 30%, the water-soluble sheet 5 is obtained.

On the other hand, the reticulated bag 1 comprises two reticulated bodies 9,
10 are connected to each other on both sides in the width direction and on one side in the vertical direction by connecting yarns. The two front and back nets 9, 10 are vertically spaced by the hanging yarn 11 at predetermined intervals in the width direction. The inside of the net-like bag 1 is divided into a plurality of compartments a by connecting in the directions.

The mesh of the mesh member 9 on the front side is set so as to be suitable for the germination and growth of vegetation bases (vegetable seeds, bulbs, lawns and bamboo runners) contained in the artificial soil material 3, The mesh of the reticulated body 10 on the side is set so as to be suitable for rooting and growing of the vegetation base. In this embodiment, both the front and back nets 9 and 10 have the width of the mesh bag 1. The size of the mesh is set so that the dimension in the direction is, for example, about 10 mm, and the dimension in the longitudinal direction of the mesh bag 1 is, for example, about 3 mm.

The net-like bag 1 not only contributes to the transportation and uniform arrangement of the artificial clay bag 2, but in addition to this, when the tubular sheet bag 4 is at least partially decomposed over time. The purpose of this invention is to prevent the artificial soil material 3 from frost heaving and flowing out. For example, a plain weave, a kami weave, a Russell weave using a corrosion-resistant synthetic resin fiber such as polyethylene, polypropylene or nylon. The artificial guest clay bag 2 is placed in the compartment a.
After the insertion, although not shown, the mouth is appropriately sewn with a sewing machine or the like.

The eyelet 13 is attached to a predetermined portion of the mesh bag 1 after the mouth is sewn or before the suturing as described above. The attachment point of the eyelet 13 is optional, but it is to be attached to at least two corners on both sides of the upper side of the mesh bag 1 when the vegetation bag M is installed on the slope, and further to the middle part of the upper side. Alternatively, it may be attached to only the four corners of the net-like bag 1, and preferably, as shown in the figure, provided at an intermediate portion of each side in addition to the four corners.

In greening the slope, a plurality of the vegetation bags M having the above structure are laid on the slope so that the vertical direction of the vertical compartments a of the bag M is directed to the vertical direction of the slope. At this time, the eyelets 13 are used to tie the vegetation bags M adjacent to each other with a string-like body, or the eyelets 13 are hooked on hooks of a legal frame formed on a slope, and are adjacent to each other. An anchor pin is driven into the eyelets 13, 13 in the overlapping portion of the vegetation bag M, or an anchor pin is appropriately driven into the overlapping portion of the vegetation bag M, so that the vegetation bag M is set on the slope. is there.

As described above, when the eyelets 13 are provided at least at two corners of the mesh bag 1, the adjacent vegetation bags M can be installed in an orderly manner, and the anchor pins can be easily driven. Although the improvement of the performance is achieved, it is not an essential condition to provide the eyelets 13 in this way.

Here, in the vegetation bag M having the above structure, since the artificial soil material 3 is filled in the bag 4 of the tubular sheet, the artificial soil material 3 may be spilled during the construction and transportation. Since the frost heaving and runoff of the artificial soil material 3 for a considerable period after the construction is effectively prevented, and the artificial soil material 3 contributes to the weight reduction of the vegetation bag M, the work of setting the bag body The performance is improved.

In addition to the fact that the bias of the artificial soil material 3 is prevented by the tubular sheet bag 4, the entire vegetation bag body M including the artificial soil bag 2 is rich in flexibility. With this vegetation bag M, the slope is constructed with a uniform thickness.

The water-soluble sheet 5 constituting the tubular sheet bag 4 is quickly dissolved by the rainfall, and the bag 4 is partially decomposed with time, so that it is suitable for the rooted surface of the plant. While the artificial soil material 3 adheres to the slope,
The vegetation base contained in the artificial soil material 3 easily germinates through the bag 4, and even if a thick bud bulb is selected as the vegetation base, the germination of the vegetation is carried out well, and It grows reliably with the supply of fertilizer and moisture.

The configuration of the vegetation bag M described above is merely an example. For example, as the bag 4 of a tubular sheet, for example, a dispersible nonwoven fabric made of soup, or this dispersible nonwoven fabric is laminated on the above-described kaya fabric. The resulting partially water-disintegrable sheet, water-soluble paper with cinnamon (Bonlick; trade name of Venus Paper Co., Ltd.) and the like can be used.

Alternatively, the entire bag 4 may be configured to be decomposed with time.
-50%, 35-45% of polypropylene fiber, and 10-3 of powdery or fibrous polyvinyl alcohol.
A water-soluble sheet of 0%, a water-soluble sheet of polyvinyl alcohol of 100%, a polymer film or a starch-based film soluble in water, and the like can be used.

In addition to the above-mentioned materials, the material of the mesh bag 1 may be jute, which is decomposed and corroded by microorganisms such as bacteria, vegetable natural fibers such as cotton and silk, paper tape and rayon-based materials. Regenerated fibers such as yarn and rayon cotton made of regenerated cellulose, blended fibers of these and synthetic fibers, and other high-strength rayons such as viscose rayon and biodegradable resin fibers, polynosic rayon and viscose rayon for tire cords, etc. Can also be suitably implemented.

The above-mentioned high-strength rayon has a large tensile strength, a small decrease in strength when wet, and maintains about 90% of the original tensile strength even after the last half year of installation.
It shows the property of corroding with time and homogenizing with the soil. If this strong rayon is used as the material of the net-like bag 1, the strength is sufficient for about six months to two years until the vegetation base germinates and grows. Because of the maintenance, artificial soil material 3 on the slope
Frost heaves and runoff are effectively prevented, and then the plant grows and grows to some extent, gradually decomposes and corrodes and eventually returns to the soil. Such secondary pollution is prevented, and is very suitable for greening slopes.

Alternatively, even for corrosive fibers, the strength of the material can be sufficiently maintained for about half a year to two years by performing the antibacterial treatment, and it is gradually decomposed and eventually decomposed.
Since it corrodes and finally returns to the soil, the anti-bacterial treated corrosion-controlling fiber can also be suitably used as a material of the mesh bag 1.

As an antibacterial treatment for the corrosive fiber, a surface water repellent treatment with a water repellent or an adhesive is generally used. However, since the decomposition and corrosion of the corrosive fiber is caused by the presence of bacteria. An antiseptic treatment of dipping or applying the corrosive fibers themselves or the nets 9, 10 knitted with the corrosive fibers to a fungicide, an antibacterial agent, an antiseptic or the like can also be suitably performed.

As the corrosive material to be subjected to the above-mentioned water-repellent treatment, various materials such as animal, vegetable, and chemical can be selected. Typical materials are natural fibers such as cotton, hemp, and pulp.Chemical materials include polyolefin-based materials that are easily corroded by chemicals, recycled fibers such as viscose rayon, other biodegradable plastics, and photodegradable materials. There is a plastic.

Among the biodegradable chemical fibers, examples of the biodegradable plastic include Tone (trade name: AMKO, USA)
), Trade name Pullulan (manufactured by Hayashibara Co., Ltd.), trade name Soa Phil (manufactured by Mitsubishi Rayon Co., Ltd.) and the like. And brand name Plastigone (made by US Idea Masters Co., Ltd.).

Even when synthetic fibers that do not decompose are used, by blending them with corrosive fibers, it is possible to obtain a net-like bag 1 that suppresses pollution. In other words, if the fiber is a blend of synthetic fiber and corrosive fiber, the synthetic fiber will not be decomposed and corroded. However, the corrosive fiber will be decomposed and corroded by microorganisms when the vegetation bases germinate and grow. Since the entirety of the mesh bag 1 is not semi-permanently left on the slope, and the pollution problem is suppressed, the blended fiber can also be suitably implemented as a material of the mesh bag 1. is there.

As the corrosive fiber of this blended fiber, for example, natural fibers such as cotton, silk and hemp, which are decomposed and corroded by microorganisms over time, and biodegradable chemical fibers such as viscose rayon can be selected. A certain tensile strength can be secured semi-permanently without being decomposed by microorganisms, for example, vinylon-based such as polyvinyl alcohol, polyester-based such as polyester, polyamide-based such as nylon, and polyacrylonitrile such as acrylic A synthetic fiber such as a synthetic fiber can be selected, and the composition thereof is preferably a mixture of a corrosive fiber of 60 to 80% and a synthetic fiber of 40 to 20%.

For the antibacterial treatment of the fiber, for example, lauryldimethylbenzylammonium chloride (trade name Meilapit V-43 manufactured by Meisei Chemical Industry Co., Ltd.)
And an antibacterial agent such as octadecyldimethylbenzylammonium chloride (trade name, Mekabinone SMB-85, manufactured by the company) is effectively used.

These are effective in suppressing the erosion of fibers by microorganisms such as bacteria.
Can reliably ensure the strength of the plant, and when the plant grows large, it loses its corrosion inhibitory effect, and the fibers are decomposed and corroded by microorganisms and homogenized with the soil. It is suitable for greening slopes.

In addition to the above, even if a mixed fiber rayon obtained by internally adding at least one of a polymer emulsion or a water-soluble polymer to a viscose solution is used, a net-like fabric suitable for slope greening without causing a pollution problem. A bag 1 can be obtained. That is, the emulsion or polymer internally added to the viscose solution is hardly corroded by microorganisms, but is decomposed with the corrosion of the mixed fiber rayon, so that the net-like bag 1 remains semipermanently on the slope. The greening of the slopes is achieved without any pollution problems.

As the mixed fiber rayon, a viscose solution composed of regenerated cellulose which is decomposed and corroded by microorganisms is added to a polymer emulsion (for example, acetic acid) which is not decomposed and corroded by microorganisms and which can compensate for a decrease in strength due to decomposition and corrosion of rayon. Either a vinyl resin, acrylic resin, ethylene vinyl acetate resin, etc.) or a water-soluble polymer (eg, polyvinyl alcohol, polyacrylamide, etc.) internally added at the stage of viscose solution, or an emulsion and polymer Both of which are internally added are used. As the composition of the mixed fiber rayon, a polymer emulsion or a water-soluble polymer is
The one internally added at a ratio of 15% is preferred.

The vegetation seeds to be mixed with the artificial soil material 3 include seeds of exotic plants such as pasture, seeds of flower plants,
Seeds of native plants such as wildflowers and trees are appropriately selected. Specifically, as forage seeds, gleaping red fescue, highland bentgrass, red top,
There are bermudagrass, Kentucky bluegrass, etc., and as flower plant seeds, there are yellow daisy, French chrysanthemum, large broiler chrysanthemum, saw, grass fly, California poppy, purple hananana, gypsophila, cosmos, celosia, kawaranashiko, garlic, etc., as the grass seed is mugwort, silver grass, Medohagi and Japanese knotweed like.

Further, examples of tree plants include red pine, yabu-shabu, weasel, yamahagi and komatsuna.
In addition, tree seeds and flower plant seeds such as annual flower plants and perennial flower plants may be appropriately mixed.

In addition to these vegetative seeds, bulbs such as tulips, lilies, and gladiolus, and lawn and bamboo runners can be selected as vegetation bases. These can be appropriately mixed with flower plant seeds and tree seeds. Alternatively, these may be classified and arbitrarily included in a plurality of artificial guest bags 2,
Flower plants, trees, bamboo grass, etc. may be grown so as to be surrounded by a lawn, or flower plants, trees, bamboo grass, etc. may be grown in a belt shape.

[0042]

As described above, according to the vegetation bag of the present invention, the artificial soil material selected so that the growth of the vegetation base does not depend on the local soil can be reduced in weight of the vegetation bag. Because it contributes to the improvement of workability and workability on the slope of the vegetation bag, the artificial soil material is filled into the bag of the tubular sheet,
The bias of the artificial soil material in the bag, including the falling of the artificial soil material, is effectively prevented, and in addition, since the entire vegetation bag body including the artificial soil bag is rich in flexibility, the vegetation The sack can be adapted to the slope well, and the slope can be constructed with a uniform thickness by the vegetation bag.

When the bag of the tubular sheet is at least partially decomposed with time, the adhesion of the artificial soil material filled in the bag to the slope and, in addition, the rooting of the vegetation base are enhanced. Even if a bud with a thick bud is selected as a vegetation base, the bud will be successfully passed through.
By inserting the artificial guest clay which decomposes at least partially with time into the plurality of compartments of the mesh bag, effective prevention of the runoff of the artificial guest material is achieved. By arbitrarily adding vegetation groups, desired plants can be classified and grown, and as a whole, ideal vegetation in which slope greening is effectively achieved with good workability and workability. It was possible to provide bags for use.
