Detailed Description of the Invention

[0001]

[Industrial field of application] The present invention is utilized in all civil engineering fields (hereinafter, description will be made for slopes) such as road slope protection, river bank protection, embankment, hillside greening, and disaster recovery. Vegetation bag for greening for sandbags.

[0002]

2. Description of the Related Art As the above-mentioned sandbags for vegetation bags for greening, there is one which is formed by sewing a net-like body having a mesh capable of germination and growth of vegetation into a bag shape. A vegetation material is appropriately mixed with vegetation seeds, fertilizer, soil conditioner, organic matter such as bark and peat moss.

Alternatively, as seen in Japanese Utility Model Publication No. 46-8105, the net body is sewn to form a bag body, and vegetation seeds or vegetation seeds and fertilizer are provided on a part of the inner surface of the bag body. Which is made by attaching
As can be seen in Japanese Patent Publication No. 19710, a part of a warp of a mesh is double-faced and a weft is knitted on each of the front and back warps, and a vegetation base material (for example, a slow-acting or ultra-slow-acting fertilizer,
A bag accommodating portion of a bag body filled with a water retention material or one or more soil improving materials) is formed, and the net body is sewn to form a bag body, and at least one of the inner and outer surfaces of the bag body is formed. There is also a vegetation bag for revegetation, which is formed by attaching vegetation seeds or vegetation seeds and fertilizer. In the vegetation bags for greening seen in these publications, soil is put in at the time of greening on the slope,
Alternatively, if necessary, vegetation materials obtained by appropriately mixing vegetation seeds, fertilizers, soil improving materials, organic substances such as bark and peat moss, and the like are added to the soil.

[0004]

The reticulate body which constitutes the above-mentioned vegetation bag is generally woven and woven by fibers made of synthetic resin, but these are different from plant-based or animal-based materials, and they are weather-rained over many years. It does not become weathered or corroded by exposure to the soil and is not homogenized with the vegetation base material and soil, and remains semi-permanently on the slope to cause pollution problems, and the growth and rooting of growing vegetation organisms. There was a problem that aggravated.

In order to avoid such an inconvenience, for example, a plant-based material such as jute or a so-called corrosive viscose rayon (regenerated cellulose) which completely corrodes even after a long period of time is used as a material. Alternatively, it has been proposed to use a corrosive biodegradable plastic as a material for weaving a mesh or bag, but these materials will not corrode after about two months have passed since they were installed on the slope. The period of 2 months is too short for seeds held in sandbags to germinate, grow well and flourish, and the tensile strength is lost during this period.
Since it is fatal in terms of preventing runoff of soil in sandbags due to rainfall and freezing, it has not been implemented so far.

The present invention has been made in view of the above-mentioned circumstances, and in terms of protection of slopes and growth of vegetation,
Sufficient tensile strength is maintained as a bag for a period of about half a year to one year after installation on the slope. After that, from the viewpoint of pollution prevention,
It is an object of the present invention to provide an ideal vegetation bag for greening, which is provided with the condition that most of the constituent materials decompose and corrode to become homogenous with the soil.

[0007]

[Means for Solving the Problems] In order to achieve the above object, a first aspect of the present invention provides a vegetation bag for greening, which is formed by sewing a net-like body formed with a mesh capable of germination and growth of vegetation into a bag shape. It is characterized in that the reticulated body is knitted and woven using a mixed fiber composed of a corrosive fiber and a synthetic fiber. Second
In the invention, a bag body is formed by sewing a mesh body in which a mesh capable of germination and growth of vegetation is formed, and at least a part of at least one of the inner and outer surfaces of the bag body has vegetative seeds or vegetative seeds. In a greening vegetation bag formed by adhering a fertilizer and fertilizer, the net-like body is knitted and woven with a mixed fiber composed of a corrosive fiber and a synthetic fiber. In a third aspect of the invention, a part of the warp threads of a mesh body on which meshes capable of germination and growth of vegetation are formed are doubled on the front and back sides, and wefts are knitted on the warp threads on the front and back sides, respectively, and the mesh body is a vegetation substrate. The accommodating portion of the filling bag is formed, and the net body is sewn to form the bag body, and at least a part of the inner and outer surfaces of the bag body is provided with vegetative seeds or vegetative seeds and fertilizer. In the vegetation bag for greening formed by adhering, the mesh-like body is knitted and woven with a mixed spun fiber composed of a corrosive fiber and a synthetic fiber.

According to a fourth aspect of the present invention, in a vegetation bag for greening, which is formed by sewing a net-like body on which a mesh capable of germination and growth of vegetation is formed into a bag shape, the net-like body is made of a high molecular emulsion or water-soluble polymer. It is characterized by being knitted and woven by a mixed fiber rayon in which at least one of them is internally added to a viscose solution. In a fifth aspect of the present invention, a bag body is formed by sewing a mesh body in which a mesh capable of germination and growth of vegetation is formed, and at least a part of at least one of the inner and outer surfaces of the bag body has vegetation seeds or In a vegetation bag for greening formed by sticking vegetation seeds and fertilizer, the reticulate body is knitted with a mixed fiber rayon in which at least one of a polymer emulsion and a water-soluble polymer is internally added to a viscose solution. It has a feature. In a sixth aspect of the present invention, a part of the warp yarns of a mesh body on which meshes capable of germination and growth of vegetation are formed are doubled on the front and back sides, and wefts are knitted on the warp yarns on the front and back surfaces of the mesh body to form a vegetation substrate on the mesh body. The accommodating portion of the filling bag is formed, and the net body is sewn to form the bag body, and at least a part of the inner and outer surfaces of the bag body is provided with vegetative seeds or vegetative seeds and fertilizer. In the greening vegetation bag that is adhered, the mesh is knitted and woven by a mixed fiber rayon in which at least one of a high molecular emulsion and a water-soluble polymer is internally added to a viscose solution.

[0009]

In the first to third inventions, the reticulate body is knitted and woven by the mixed fiber composed of the corrosive fiber which is decomposed and corroded by the microorganism and the synthetic fiber which is not decomposed by the microorganism. According to the body, the corrosive fiber is decomposed and corroded in a short period of time, the synthetic fiber also becomes brittle with time and the tensile strength decreases, but the decrease in the tensile strength of this synthetic fiber is very slow, The net-like body can retain a considerable tensile strength for a long period of time. That is, by woven or knitting a mesh body using a mixed fiber in which a corrosive fiber and a synthetic fiber are mixed in a predetermined ratio, for example, a corrosive fiber 60 to 80% and a synthetic fiber 40 to 20%, It is possible to maintain the strength required for the greening vegetation bag during the period until it grows and grows to some extent (half a year to one and a half years after the installation of the greening vegetation bag on the slope). And by the time the vegetation grew to some extent and flourished,
Corrosive fibers are decomposed and corroded by microorganisms and become homogenized with soil, and although synthetic fibers remain in part, most of the reticulate body is homogenized with soil, so it does not lead to a serious pollution problem, and environmental It can contribute to improvement.

In the fourth to sixth inventions, the reticulate body is knitted or woven by the mixed fiber rayon in which the emulsion or the polymer which is hardly decomposed and corroded by the microorganism is internally added. According to such a constitution, the viscose rayon itself. Is decomposed and corroded by microorganisms and its strength decreases with time, but the tensile strength of the mixed fiber rayon is increased by internally adding an emulsion or polymer at the stage of the viscose solution. Will be done very slowly. On the other hand, the viscose solution originally contains a large amount of hydroxyl groups, but by adding an emulsion or a polymer to the viscose solution, the total amount of hydroxyl groups in the mixed fiber rayon decreases, and the mixed fiber Moisture absorption in the mesh when knitted with rayon is reduced, and decomposition and corrosion of the mixed fiber rayon by microorganisms can be suppressed, and the increase in tensile strength of the mixed fiber rayon due to the addition of the emulsion or polymer is synergistic. As a result, the strength required for the vegetation bag for revegetation can be maintained for a period of about six months to one year after installation on the slope. The emulsion and polymer added internally to the mixed fiber rayon are not easily corroded by microorganisms, but the emulsion and polymer are decomposed by the corrosion of rayon and homogenized with the soil, so the vegetation bag for greening is semipermanent. It does not lead to pollution problems such as remaining on slopes, and can contribute to the improvement of the environment.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an example of a vegetation bag 1 for greening configured as a sandbag, and FIG. 2 shows a reticulated body 2 having a mesh for allowing germination and growth of vegetation which constitutes the vegetation bag 1. The upper edge 2a of the mesh body 2 is folded back to form the insertion portion 4 of the binding string 3, and the mesh body 2 is folded in the left-right direction so that the left and right edges 2b and 2c and the lower edge sides 2d, 2e
3 by sewing the sandbag bag body 5 shown in FIG.
Is configured. At the time of greening of the slope, vegetation material in which soil is appropriately mixed with vegetation seeds, fertilizer, water retaining material, soil improving material, etc. is put into the bag body 5, and the mouth is tightly bound to form the sandbag shown in FIG. The sandbags are brought to a predetermined position on the slope, and the sandbags are attached or stacked in a lattice frame on the slope.

In the present invention, the mesh 2 which constitutes the above-mentioned greening vegetation bag 1 is knitted and woven by a mixed spun fiber composed of corrosive fibers and synthetic fibers, and a thread for sewing the mesh 2 into a bag and The binding string 3 for binding the mouth is also made of blended fiber. As the corrosive fiber of this mixed spinning fiber, for example, natural fibers such as cotton, silk, hemp that are decomposed and corroded by microorganisms over time, biodegradable chemical fibers such as viscose rayon, and the like can be selected. For example, polyvinyl alcohol or other vinylon type, polyester or other polyester type, nylon or other polyamide type, and acryl or other polyacrylonitrile type, etc. Synthetic fiber can be selected. The composition of the mixed fiber is preferably a mixture of corrosive fiber 60 to 80% and synthetic fiber 40 to 20%.

Next, viscose rayon was used as the corrosive fiber, and polyester was used as the synthetic fiber.
When the tensile strength of the blended fiber blended at a ratio of 0% and viscose rayon alone as a comparative example was tested, the results shown in Table 1 were obtained.
The tensile test of both of them was started in July because the activity of microorganisms was high and the strength decrease was most likely to occur due to the decomposition and corrosion of the fiber.

[0015]

[Table 1]

As is clear from Table 1, the viscose rayon used as a comparative example had a tensile strength of 0 after about 2 months, whereas in the mixed fiber, the tensile strength was gradually increased by microorganisms from the time of installation. It was found that the tensile strength after one and a half years has passed was 1.2 kg, although the strength decreased due to decomposition and corrosion. If the tensile strength per strand of the mixed fiber constituting the reticulate body 2 is 0.5 Kg or more, runoff of soil in the sandbag due to rainfall or freezing when the bag body 5 is installed on the slope is prevented. Therefore, if the tensile strength is as high as 1.2 kg, protection of the slope is sufficiently achieved.

In the vegetation bag 1 for greening according to the first aspect of the invention, the strength of the net material 2, the sewing thread, and the string material 3 is sufficiently maintained for about half a year to one and a half years, and thereafter, Since the strength decreases with the passage of time, corrosive fibers having the property of eventually corroding and becoming homogenous with soil, and a mixed fiber made of synthetic fibers is selected, of course, during the above period, Over a period longer than that, runoff of soil and vegetation material in the bag body 5 is effectively prevented. During this period, the vegetation seeds in the bag body 5 germinate, grow, and flourish, so that the greening protection on the slope is achieved and
Even if the growth and rooting of the vegetation are improved by homogenization with soil due to the subsequent corrosion of the corrosive fibers, and even if most of the vegetation bag 1 (corrosive fibers) is corroded, the vegetation will be up to that point. As a result, the protection of slope greenery will be maintained permanently.

The above vegetation material may be treated with sewage sludge or the like to form a powder, for example, PM C-Zai (registered trademark of Jomo Green Industry Co., Ltd.) as an extender, or Since the PM C-Zai has fertilizing properties and water-retaining properties, the sandbag may be configured by accommodating only the PS C-Zai with vegetation seeds in the bag body 5. In addition, in the above-mentioned slope greening, generally, a means of bringing sandbags into which the soil and vegetation materials have been put into the greening vegetation bag 1 is used.
A water-retaining material, soil conditioner, PM C-Zai, and other dry organic vegetation materials that have been appropriately mixed and mixed with organic substances such as bark and peat moss are pumped up to a predetermined point on the slope, and greening vegetation is applied to that point. It is also possible to take a bag 1 and put the above-mentioned vegetation material in the vegetation bag 1 for greening to form a sandbag, and to attach the sandbag to the sloped lattice frame or stack it. , Compared with the method of bringing sandbags to the slope, safe and efficient protection of slope slopes can be achieved.

FIGS. 4 to 6 show an example of a vegetation bag 1 for greening which constitutes a sandbag of another embodiment. In this embodiment, a reticulated body 2 is made of a mixed fiber composed of corrosive fibers and synthetic fibers.
Is woven and woven on the entire half surface 2A of one side of the mesh body 2,
As shown in FIG. 4, suitable vegetation seeds 6 such as grass and wild grass, a fertilizer 7 and a water retention agent 8 are attached by a water-soluble foaming adhesive 9 such as polyvinyl alcohol.
Then, the upper end edge 2a of the mesh body 2 is folded back to tie the cord 3
The half part 2A on which the vegetation seeds 6 and the like are attached is folded in two and the left and right edges 2b and 2c and the lower edges 2d and 2e are sewn together. The bag main body 5 for sandbags shown in FIG. 6 is constructed.

Although the vegetation seeds 6, the fertilizer 7 and the water retention agent 8 are directly adhered to the reticulate body 2, in addition, so-called turfed grass in which the vegetation seeds are sandwiched between two water-soluble papers. It is possible to employ means such as sticking the to the mesh body 2. Further, the vegetation seeds 6 and the like are adhered to the entire half surface 2A of one side of the bag body 5, and the vegetation seeds 6 and the like are directed to the outer surface to form the bag body 5. It may be directed to the inner surface, or the vegetation seeds 6 may be part of the half surface 2A,
It can be carried out by adhering it to the entire surface of one side or a part thereof, and further it can be carried out by adhering it to the entire area of both surfaces of the mesh body 2 or a part thereof.

When greening the slope, only the soil is put into the bag body 5, or a vegetation material obtained by appropriately mixing the soil with vegetation seeds, fertilizers, water retention materials, soil improving materials, PM C-Zai, etc. Figure 6 with the mouth tightly bound
Make up the sandbag shown in. The sandbags are brought to a predetermined position on the slope, and the vegetation seeds 6 and the like are directed outward, so that the sandbags are stuck or stacked in the lattice frame of the slope. In addition to the vegetation seeds in the bag body 5, the vegetation seeds 6 attached to the vegetation bag 1 germinate, grow, and flourish, so that the greening protection on the slope can be achieved better. It

FIG. 7 shows an example of a vegetation bag 1 for greening which constitutes a sandbag of another embodiment. In this embodiment, when the reticulate body 2 is knitted or woven by the mixed fiber made of corrosive fibers and synthetic fibers, as shown in FIG. 8, a range corresponding to 5 to 6 wefts 10 in a part of the reticulated body 2. The warp threads 11 placed every other side are doubled on the front and back sides,
A weft yarn 10 is alternately entwined with the weft yarns 11 to form a bag accommodating portion 12 in a part of the mesh body 2. And the bag accommodating portion of the mesh body 2
An appropriate vegetation seed 6 such as grass or wild grass, a fertilizer 7 and a water retention agent 8 are attached to the entire half surface 2B on the side opposite to 12 with a water-soluble foaming adhesive 9 such as polyvinyl alcohol, or water-soluble. The so-called tension turf in which vegetation seeds are sandwiched between two sheets of paper is attached to the reticulate body 2 to form the vegetation seeds 6
The net body 2 is folded in two so that the half surface 2B to which the above is adhered faces outward, and the two sides are sewn together to form the bag body 5.

As shown in FIG. 9, the bag accommodating portion 12 has a bag body 14 filled with one or more vegetation base materials 13 such as slow-acting or ultra-slow-acting fertilizers, water retention materials, and soil conditioners. , And vegetation seeds, fertilizers, water retention materials, soil improvement materials, PM C-Zai, other organic substances such as bark and peat moss, soil, etc. are appropriately placed in the bag body 5. When the vegetation base material 13 contains vegetation seeds as the bag body 14 to be filled with the vegetation base material 13, it is possible to select a relatively thin non-woven fabric obtained by mixing pulp or suf or these vegetation seeds. It is suitable for germination. Further, when the vegetation base material 13 to be filled in the bag body 14 does not contain vegetation seeds, if pulp or rayon or a relatively thick non-woven fabric made by mixing these is selected, the fertilizer slowly exudes and the fertilizer is effective. Is preferable because it can be maintained for a long period of time, or runoff of the soil improving material, the water retaining material, etc. can be effectively prevented, but it is not limited thereto.

By the way, the vegetation bag 1 according to each of the above embodiments
As a constituent material of the reticulate body 2, a mixed fiber made of corrosive fiber and synthetic fiber is selected, and 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. Even if the mesh body 2 is knitted and woven by the above and the sandbag is constituted by this mesh body 2, the protection of the greening of the slope is suitably achieved.

That is, although the viscose rayon itself is decomposed and corroded by microorganisms and its strength decreases with time,
By internally adding an emulsion or a polymer at the stage of the viscose solution, the tensile strength of the mixed fiber rayon is increased, and the viscose solution originally contains a large amount of hydroxyl groups. By adding the polymer internally, the total amount of hydroxyl groups in the mixed fiber rayon decreases, and therefore, the moisture absorption in the vegetation bag when knitting or weaving with this mixed fiber rayon decreases, so that the mixed fiber rayon is decomposed by microorganisms. Corrosion can be suppressed, and the suppression of this decomposition corrosion and the increase in tensile strength of the mixed fiber rayon by the internal addition of emulsion or polymer synergize with each other. It is possible to maintain the required strength. On the other hand, polymers and emulsions are not easily corroded by microorganisms, but these polymers and emulsions are decomposed by the corrosion of rayon and become homogenized with the soil, and the vegetation bag for greening may remain semipermanently on the slope. Nonetheless, this mixed fiber rayon can also be preferably used for greening the slope.

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, vinyl acetate resin, which is not decomposed and corroded by microorganisms and compensates for the decrease in strength due to decomposition and corrosion of rayon. Acrylic resin, ethylene vinyl acetate resin, etc.) or water-soluble polymer (eg, polyvinyl alcohol, polyacrylic amide, etc.) internally added at the stage of viscose solution, or both emulsion and polymer The one internally added is used. The composition of the mixed fiber rayon is preferably a viscose solution in which a high molecular emulsion or a water-soluble polymer is internally added at a rate of 2 to 15%.

Next, a mixed denier of 1000 denier in which 5% of a vinyl acetate resin emulsion was internally added to viscose rayon as a polymer emulsion, and 1000 denier viscose rayon as a comparative example were used alone. When the tensile strength was tested, the results shown in Table 2 were obtained. Incidentally, the tensile test for both was started in July, as in the case described above, because the activity of microorganisms was high and the decrease in strength due to the decomposition and corrosion of the fiber was most likely to occur.

[0029]

[Table 2]

As is clear from Table 2, the viscose rayon used as a comparative example had a tensile strength of 0 after about 2 months, whereas in the mixed fiber rayon,
Although the strength gradually decreases due to decomposition and corrosion by microorganisms after installation on the slope, the tensile strength after one year is 0.6K
Since there is also g, it can be understood that the greening protection of the slope is also suitably achieved by the greening vegetation bag knitted and woven with this mixed fiber rayon.

[0031]

As described above, in the first to third inventions, the blended fiber composed of the corrosive fiber and the synthetic fiber is selected as the constituent material of the reticulated body. For a period of about one and a half years, the reticulate body will be able to retain the necessary strength, and the runoff prevention of soil in the sandbag due to rainfall and frost heaving and the protection of slope greening will be effectively achieved. Then, when the plant life grew and proliferated to a certain extent, most of the reticulate body was decomposed and corroded and homogenized with the soil, and most of the reticulated body remained, although some synthetic fibers remained. Since it is homogenized with the soil, it does not cause a serious pollution problem and can contribute to the improvement of the environment.

In the fourth to sixth inventions, the mixed fiber rayon in which at least one of the high molecular emulsion and the water-soluble polymer is internally added to the viscose solution is selected as the constituent material of the reticulate body. Similarly to the above, the reticulate body can retain the necessary strength for a predetermined period until the plant life grows and grows to some extent, and eventually almost all of the reticulate body is decomposed and corroded to become homogenized with the soil. Therefore, it does not lead to pollution problems and can contribute to the improvement of the environment. As a whole, the tensile strength is maintained for the necessary period for the protection of slopes and the growth of plant life, and from the viewpoint of pollution prevention. It is now possible to provide a vegetation bag made of an ideal material with the condition that most of the constituent materials are homogenized with the soil.
