Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vegetation bag used for a greening method such as a slope on a hillside or a river dike, or a slope formed along with land development.

[0002]

[Prior art]

 Conventionally, for the purpose of greening to protect the slope and preserve the landscape, for example, vegetation seeds and fertilizers are mixed with the local soil and filled in a vegetation bag, and this so-called sandbag is installed so that it is attached to the slope. The construction method was taken.

[0003]

[Problems to be solved by the device]

 However, most of the local soil contains large lumps of stone, and since the sandbag becomes a heavy material, the workability is poor, and a hanging thread is provided inside the bag to expand the bag. Even if the stains are forcibly regulated, the soil is biased toward the lower side of the vegetation bag and the vegetation bag swells, making it difficult to handle, and the soil bias hinders uniform slope construction. In addition, the vegetation bag floated up, making it less familiar with the slope, and there was a problem in terms of poor workability as a whole.

Moreover, the local soil is not always suitable for growing vegetation seeds, and as described above, it is often rather thin due to the inclusion of large stone blocks. Even if the vegetation seed germinated, there was a problem that it was difficult to root and withered.

Further, if the mesh of the vegetation bag is increased in order to improve the germination of the vegetation seeds mixed in the local soil, the soil filled in the vegetation bag will be more likely to spill and the mesh will be reduced. On the contrary, there was a problem in that the germination would worsen. In addition, from this, there was a problem that bulbs with thick shoots could not be selected as vegetation bases to be mixed with local soil.

The present invention has been made in view of such circumstances, is excellent in workability and workability, and has a uniform slope on the slope, and as a vegetation base. The aim is to provide a bag for vegetation in which vegetation seeds and bulbs, as well as lawns and bamboo runners, can be germinated and grown well even if they are selected.

[0007]

[Means for Solving the Problems]

 The vegetation bag according to the present invention, which has achieved the above-mentioned object, is filled with an artificial soil material composed of vegetation material mixed with vegetation material in a tubular sheet bag that is at least partially decomposed with time. In addition, while closing the mouth of the bag for filling the soil material, an artificial soil bag is formed, while the front side is suitable for germination and growth of vegetation base and the back side is suitable for root growth of vegetation base. The mesh bodies are connected to each other on both sides in the width direction and one side in the vertical direction to form a mesh bag, and the two mesh bodies on the front and back sides of the mesh bag are vertically arranged with a hanging thread at predetermined intervals in the width direction. It is characterized in that the inside of the mesh bag is divided into a plurality of compartments by connecting them, and the artificial soil bag is inserted into each of the compartments, and the mouth portion of the mesh bag is closed. .

As the above-mentioned vegetation material, for example, one or more of soil improvers, general chemical fertilizers, other organic materials such as bark compost and peat moss, and inorganic materials such as vermiculite and partlite are selected and used as vegetation bases. Is selected from one or more of vegetation seeds, bulbs, lawns and bamboo runners.

As the bag of the tubular sheet, not only those that partially decompose with time but also those that decompose all over the bag are used. As the mesh of the mesh bag, corrosive, corrosion-resistant and corrosion-adjusting fibers are used. Any of the fibers is used.

[0010]

[Action]

 According to the vegetation bag body of the present invention configured as described above, since the artificial soil material is filled in the bag of the tubular sheet, the artificial soil material is spilled and biased in the bag. Since the runoff is effectively prevented and the entire vegetation bag, including the artificial soil bag, is highly flexible, the vegetation bag is well adapted to the slope and the slope is the vegetation bag. It is constructed to a uniform thickness depending on the body.

In addition, the artificial soil material contributes to the weight reduction of the vegetation bag and the growth of the vegetation substrate, and at the same time, the bag of the tubular sheet is at least partially decomposed, so that the artificial soil material Adhesion to slopes and, in turn, rooting properties of plants are enhanced, and even if thick bulbs with thick shoots are selected as vegetation base, they can be successfully sprouted and workability and workability are good. Slope greening is effectively achieved in the state.

【Example】

 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. The vegetation bag M is formed by dividing the inside of the mesh bag 1 into a plurality of compartments a, It is made by inserting a flexible rod-shaped artificial earthen bag 2 into the bag.

More specifically, the artificial customer bag 2 is made of one or more of soil improvers, general chemical fertilizers, other organic materials such as bark compost and peat moss, and inorganic materials such as vermiculite and partlite. The vegetation material is mixed with one or more kinds of vegetation seeds, bulbs, lawns and bamboo grass runners as vegetation bases, and the artificial soil material 3 is filled into a tubular sheet bag 4 that at least partially decomposes with time, and , The mouth of the bag 4 is closed by means such as adhesion.

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, 35 to 45% of polypropylene fiber, and powder. On one side of the water-soluble sheet 5 composed of 10 to 30% of linear or fibrous polyvinyl alcohol, a kaya having a texture suitable for budding of the vegetation base contained in the artificial soil material 3 (for example, The vinylon 30 is composed of ten warp yarns 6 of 30 counts and staple 6 yarns / inch weft yarns 7) 8 which are joined to each other when the water-soluble sheet 5 is manufactured by skiage. The kaya 8 is joined and integrated with the water-soluble sheet 5 by the polyvinyl alcohol which is the constituent material of 5.

By using this joining means to dissolve only the water-soluble sheet 5 over time, the bag 4 of the tubular sheet has a property of partial time-dependent decomposition. The composition of the water-soluble sheet 5 is not limited to the above proportion, and most preferably, the pulp fiber is made of softwood and the polypropylene fiber is made of 2 denier and 5 mm long. However, as the polyvinyl alcohol, fibers having a thickness of 1 mm and a length of 3 mm were used, and 35 to 45% of these pulp fibers, 35 to 45% of polypropylene fibers and 20 to 30% of polyvinyl alcohol were used. To obtain the water-soluble sheet 5.

On the other hand, the reticulated bag 1 is composed of two reticulated bodies 9, 10 on the front and back sides, which are connected to each other on both sides in the width direction and one side in the longitudinal direction by connecting threads. The inside of the reticulated bag 1 is divided into a plurality of compartments a by vertically connecting the reticulated bodies 9 and 10 at a predetermined interval in the width direction with a hanging thread 11.

The mesh of the reticulate body 9 on the front surface side is set to a mesh suitable for germination and growth of vegetation bases (vegetation seeds, bulbs, lawns and bamboo grass runners) contained in the artificial soil material 3, The mesh size of the mesh body 10 on the side is set to a mesh size suitable for root growth of the vegetation base. In this embodiment, both of the mesh bodies 9 and 10 of the two front and back sides have the width of the mesh bag 1. The mesh size is set so that the size in the direction is, for example, about 10 mm, and the size in the longitudinal direction of the mesh bag 1 is, for example, about 3 mm.

It is a matter of course that the mesh bag 1 contributes to the transportation and the even arrangement of the artificial soil bag 2, but in addition to this, when the tubular sheet bag 4 is at least partially decomposed with time. In order to prevent the artificial soil material 3 from freezing and running off, for example, using a corrosive resistant synthetic resin fiber such as polyethylene, polypropylene or nylon, plain weave or Karami weave, A Russell weave is used, and after inserting the artificial soil bag 2 into the compartment a, although not shown, its mouth is appropriately sewn with a sewing machine or the like.

Then, after the mouth is sewn as described above, or before the sewn, the eyelet 13 is attached to a predetermined portion of the reticulated bag 1 in advance. This eyelet 13 may be attached at any location, but it should 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 also at the middle of the upper side. It may be attached, or may be attached only to the four corners of the reticulated bag 1, and preferably, as shown in the figure, it is also provided in the middle portion of each side.

When greening the slope, a plurality of the vegetation bag bodies M having the above-mentioned configuration are spread over the slope with the partition direction of the compartment a, which is the vertical direction, of the bag body M oriented vertically. . At this time, using the above eyelets 13, the adjacent vegetation bags M are tied together with a string-like body, or the eyelets 13 are hooked on the hooks of the frame formed on the slope, and they are also adjacent to each other. Anchor pins are driven into the eyelets 13, 13 in the overlapped portion of the vegetation bag M, or appropriately, into the overlapped portion of the vegetation bag M as well, so that the vegetation bag M is sloped. Install it.

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

Here, in the vegetation bag body M having the above-mentioned configuration, since the artificial soil material 3 is filled in the tubular sheet bag 4, it is possible to prevent the artificial soil material 3 from spilling during construction transportation. Since the artificial soil material 3 is effectively prevented from frost-up and runoff during a considerable period after the construction work, and the artificial soil material 3 contributes to the weight reduction of the vegetation bag M, the bag installation is not required. Workability is improved.

In addition to the prevention of the deviation of the artificial soil material 3 by the bag 4 of the cylindrical sheet, the entire vegetation bag M including the artificial soil bag 2 is highly flexible. The slope surface is constructed to have a uniform thickness by the vegetation bag M.

Then, the water-soluble sheet 5 constituting the tubular sheet bag 4 is rapidly dissolved by the rainfall, and the bag 4 is partially decomposed with time, so that it is suitable for the rooting surface of the plant. While the artificial soil material 3 is closely attached to the slope, the vegetation base contained in the artificial soil material 3 easily sprouts through the bag 4, and even if a thick-bud bulb is selected as the vegetation soil, The seedlings are sprouting well, and the seedlings that have sprouted receive the fertilizer and water to grow reliably.

The configuration of the vegetation bag M described above is an example. For example, as the tubular sheet bag 4, for example, a dispersible non-woven fabric made of a staple material, or the dispersible non-woven fabric is laminated on the above-mentioned kaya fabric. The resulting partially water-decomposable sheet, water-soluble paper with kanreisha (Bonrick; 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, and in that case, for example, 30 to 50% of pulp fibers, 35 to 45% of polypropylene fibers, powder or fibers. A water-soluble sheet containing 10 to 30% of polyvinyl alcohol, a water-soluble sheet containing 100% polyvinyl alcohol, a polymer film soluble in water, a starch film, and the like can be used.

As the material of the mesh bag 1, in addition to the above-mentioned materials, for example, jute, which is decomposed and corroded by microorganisms such as bacteria, natural fibers such as cotton and silk, paper tape and rayon-based materials are used. Yarn, regenerated fibers such as rayon cotton made of regenerated cellulose, blended fibers of these and synthetic fibers, viscose rayon, biodegradable resin fiber, strong rayon such as polynosic rayon and viscose rayon for tire cord. Can also be suitably implemented.

The above-mentioned high-strength rayon has a large tensile strength and a small decrease in strength when wet, and maintains about 90% of the initial tensile strength even after the half year of installation, and thereafter, with the passage of time. It exhibits the property of corroding and homogenizing with soil. If this strong rayon is used as the material for the mesh bag 1, it should maintain sufficient strength for about 6 months to 2 years until the vegetation base germinates and grows. Therefore, freezing and runoff of the artificial soil material 3 on the slope are effectively prevented, and after that, the plant gradually decomposes and grows and grows to some extent. Secondary pollution is prevented as in the case of using synthetic resin fibers that do not semi-permanently deteriorate, and it is extremely suitable for greening slopes.

Alternatively, even if the fiber is corrosive, the material strength can be sufficiently maintained for about half a year to two years by subjecting it to antibacterial treatment, and eventually it gradually decomposes and corrodes, and finally becomes soil. Because of this, the anti-corrosion treated corrosion-controlling fiber can also be suitably used as the material of the mesh bag 1.

As the antibacterial treatment for this corrosive fiber, a surface water repellent treatment with a water repellent or an adhesive is generally used, but the decomposition / corrosion of the corrosive fiber is also due to the presence of bacteria. Therefore, the preservative treatment in which the corrosive fibers themselves or the net-like bodies 9 and 10 woven with the corrosive fibers are immersed or applied in an antifungal agent, an antibacterial agent, an antiseptic agent or the like can be suitably carried out.

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. For example, the animal material may be skin, hair or plant material. Typical materials are natural fibers such as cotton, hemp, and pulp.As chemical materials, polyolefin-based materials easily corroded by chemicals, recycled fibers such as viscose rayon, and other biodegradable plastics and optical fibers. There is degradable plastic.

Examples of biodegradable plastics among the biodegradable chemical fibers include Tone (trade name, manufactured by AMKO, USA), Pullulan (trade name, manufactured by Hayashibara Co., Ltd.), Sore Phil (trade name, manufactured by Mitsubishi Rayon Co., Ltd.) Etc., and as the photodegradable plastics, for example, trade name Polygrad (manufactured by Anvais, USA), trade name Plastigon (manufactured by Ideamasters, USA) and the like are used.

Even when synthetic fiber that does not decompose is used, by mixing it with corrosive fiber, it is possible to obtain the reticulated bag 1 that is intended to prevent pollution. In other words, if the fiber is a mixed fiber of synthetic fiber and corrosive fiber, the synthetic fiber will not be decomposed and corroded, but by the time the vegetation substrate germinates and grows, the corrosive fiber will be decomposed and corroded by the soil. Since the whole reticulated bag 1 does not remain semi-permanently on the slope because it is homogenized, and pollution problems are suppressed, this blended fiber can also be suitably implemented as a material for the reticulated bag 1. is there.

As the corrosive fibers of the mixed fiber, natural fibers such as cotton, silk and hemp that are decomposed and corroded by microorganisms over time and biodegradable chemical fibers such as viscose rayon can be selected. For example, polyvinyl alcohol or other vinylon-based material, polyester or other polyester-based material, nylon or other polyamide-based material, or acrylic or other polyacryl-based material that can ensure the prescribed tensile strength semipermanently without being decomposed by microorganisms. Nitrile-based synthetic fibers can be selected, and the composition thereof is preferably a mixture of corrosive fibers 60 to 80% and synthetic fibers 40 to 20%.

For the antibacterial treatment of this fiber, for example, lauryl dimethylbenzylammonium chloride (Meira Pit V-43 manufactured by Meisei Chemical Industry Co., Ltd.) and octadecyldimethylbenzyl ammonium chloride (Make Binone SMB manufactured by the same company) Antibacterial agents such as -85) are effectively used.

Since these effectively suppress the corrosion of fibers by microorganisms such as bacteria, it is possible to reliably secure the strength of the reticulated bag 1 for a certain period of time until the vegetation groups germinate and grow to some extent. This is also suitable for slope revegetation because the plant loses its corrosion-inhibiting effect when it grows large, and the above fibers are decomposed and corroded by microorganisms and become homogenous with the soil.

In addition to these, a mixed fiber rayon obtained by internally adding at least one of a high-molecular emulsion and a water-soluble polymer to a viscose solution is also used from the viewpoint of slope greening without pollution problems. The reticulated bag 1 can be obtained. That is, the emulsion or polymer internally added to the viscose solution is not easily corroded by microorganisms, but is decomposed due to the corrosion of the mixed fiber rayon, so the mesh bag 1 is semipermanently on the slope. There is no remaining, and slope greening is achieved without pollution problems.

As this mixed fiber rayon, a viscose solution composed of regenerated cellulose that is decomposed and corroded by microorganisms is a polymer emulsion that is not decomposed and corroded by microorganisms and can compensate for the strength decrease due to decomposition and corrosion of rayon ( For example, vinyl acetate resin, acrylic resin, ethylene vinyl acetate resin, etc.) or water-soluble polymer (eg, polyvinyl alcohol, polyacrylic amide, etc.), which is internally added at the stage of the viscose solution, or The one in which both the emulsion and the polymer are internally added is used. The composition of the mixed fiber rayon is preferably a viscose solution in which a polymer emulsion or a water-soluble polymer is internally added at a ratio of 2 to 15%.

As the vegetation seeds to be mixed with the artificial soil material 3, seeds of exotic plants such as grass and seeds of native plants such as flower plant seeds, wild grass and trees are appropriately selected. Specifically, grass seeds include the Gleeping Red Fescue, Highland Bentgrass, Red Top, Bermudagrass, Kentucky Bluegrass, etc., and flower plant seeds include yellow daisies, French chrysanthemums, danishiki chrysanthemums, saw grass, Haetori pink, California poppy, Murasakihanana, Baby's Breath, cost Moss, cockscomb, Kawaranadeshiko, there is a Gaillardia pulchella, etc., also, it is a wild grass seed, a mugwort, Japanese pampas grass, Medohagi, the Japanese knotweed and the like.

Further, the tree plants include red pine, yashabu, weasel, yamahagi, komatsuna, and the like. In addition, flower plant seeds such as annual flower plants and perennial flower plants and tree seeds may be appropriately mixed.

In addition to these vegetation seeds, bulbs such as tulips, lilies, gladiolus, lawns and bamboo runners can be selected as vegetation bases, and these are appropriately mixed with flower plant seeds and tree seeds. Alternatively, these may be classified into different types and optionally contained in a plurality of artificial bags 2 to grow flower plants, trees, bamboo grass, etc. so that they are surrounded by lawn, or flower plants, trees, bamboo grass, etc. You may make it grow like a belt.

[Effect of device]

 As explained above, according to the vegetation bag body of the present invention, the artificial soil material selected so that the growth of the vegetation base does not depend on the local soil contributes to the weight reduction of the vegetation bag body. Therefore, the workability and workability on the slope of the vegetation bag can be improved, and since the artificial soil material is filled in the tubular sheet bag, Since the uneven distribution of the artificial soil material in the bag including the spillage is effectively prevented, and the entire vegetation bag body including the artificial soil bag is highly flexible, the vegetation bag body is The slope can be adapted to the slope well, and thus the slope can be applied to a uniform thickness by the vegetation bag.

Then, the bag of the tubular sheet is at least partially decomposed with time, so that the adhesiveness of the artificial soil material filled in the bag to the slope and the rooting property of the vegetation base are increased, and Even if a thick-bud bulb is selected as the vegetation base, the bud can be successfully sprouting, and the artificial soil bag that decomposes at least partially with time is inserted into the compartments of the mesh bag. By doing so, effective prevention of runoff of artificial soil material was achieved, and by adding vegetation groups to multiple artificial soil bags, desired plants could be classified and grown. As a whole, we have now been able to provide an ideal vegetation bag that effectively achieves greening of slopes with good workability and workability.
