Description

[Detailed Description of the Invention] (Technical Field) The present invention prevents collapse of slopes due to rain, melting snow, etc. by placing them on slopes such as embankments and cut-up slopes and greening the slopes. The present invention relates to a bag for vegetation sandbags used for stabilization, and more particularly to a bag for vegetation sandbags that can be suitably used in various methods of construction.

(Prior Art) Many types of vegetation sandbags have been proposed in the past. For example, there is a vegetative sandbag bag constructed by forming a vegetative zone by sandwiching seeds and fertilizers between paper or nonwoven fabric sheets, and attaching this vegetative zone inside the sandbag bag. When soil is placed inside such a vegetation sandbag, the vegetation zone may be displaced toward the bottom of the sandbag or may be damaged. This happens when,
Seeds of plants may not germinate uniformly, but may germinate unevenly in one spot, or may not germinate due to interference from large amounts of surrounding soil.

In order to prevent the vegetation belt from shifting toward the bottom of the sandbag, it is necessary to fix the vegetation belt to the sandbag. However, in order to do this, it is necessary to attach the vegetation belt to the sandbag during production of this sandbag, and this work is a major cause of increasing the cost of this type of vegetation sandbag.

On the other hand, even if the vegetation zone and the sandbag bag are integrated, when the soil inside the sandbag sinks due to rainfall, the vegetation zone and the sandbag bag will separate from the soil. When this happens, the vegetation zone becomes suspended in the air, drying out and hardening, making it difficult for seeds in the vegetation zone to germinate, and even if they do germinate, their roots will not reach the soil and the seeds will wither and die. Of course.

A further problem is that it is extremely difficult for seeds to tear through the paper or non-woven fabric that makes up the above-mentioned vegetation zone and germinate, and it is also extremely difficult for seeds to germinate by tearing through the paper or non-woven fabric that makes up the above-mentioned vegetation zone. occurred frequently.

As a means to solve the above problem, the use of the above-mentioned vegetation belt made of paper, nonwoven fabric, etc. can be stopped, and a suspension of water-soluble adhesive such as polyvinyl alcohol can be sprayed directly onto the net bag, or applied with a roller. There is a method in which the seeds are glued to the mesh bag after the seeds have been soaked. However, it is very difficult to spray or roll this water-soluble adhesive suspension onto a net bag, and it takes time to dry the adhesive suspension, and it is extremely difficult to completely dry the suspension. There is also. In particular, when the net bag is made of synthetic resin such as polypropylene, its heat resistance temperature is low, so the net bag must be dried at a low temperature that matches this heat resistance temperature, and the drying process takes a considerable amount of time. It takes a lot of time.

Furthermore, in the bag for vegetation sandbags formed in this way, seeds etc. are merely superficially adhered with polyvinyl alcohol. Seeds often easily fall out of net bags during production or transportation, making it impossible to use them effectively. Further, in this bag for vegetation sandbags, when soil is placed inside the bag, seeds and the like accumulate at the bottom. When this happens, plant seeds do not germinate all over, but often germinate unevenly in one spot, or are hindered by the large amount of surrounding soil and do not germinate. Therefore, even if there is a bag for vegetation sandbags in which seeds or the like are simply adhered with an adhesive, the manufacturing cost is high.

(Objective of the Invention) The present invention was made in view of the above-mentioned circumstances, and its objectives are: ■ To have a structure that allows seeds to germinate reliably; q) To reduce costs with a simple structure. ■Seeds do not fall out easily during transportation and placement work.■Sandbags for vegetation can be used to ensure that the bags themselves will not corrode, at least until the slope is stabilized. It is about providing. Still another object of the present invention is (6) a bag for vegetation sandbags that is capable of reliably retaining plant growth materials such as seeds, fertilizers, and soil conditioners between the water-soluble film and the net bag. Our goal is to provide the following.

(Structure) In order to achieve the above object, the gist of the first invention of the present application is as follows: In a vegetation sandbag comprising seeds and plant growth material sandwiched between the bag and the bag, the water-soluble film and the net bag are bonded together by surface dissolution of the water-soluble film by water, and the seeds and plant growth material are bonded together. A second aspect of the present invention resides in a bag for vegetation sandbags, characterized in that a material is adhesively sandwiched between the water-soluble film and a mesh bag, and the second aspect of the present invention is a coarse mesh bag.
, a water-soluble film stuck to the inner surface of the net bag, and seeds and plant growing materials sandwiched between the water-soluble film and the net bag, wherein the water-soluble film Alternatively, the water-soluble film and the net bag are adhered to each other using an adhesive attached to the net bag, and the seeds and plant growing materials are adhered and sandwiched between the water-soluble film and the net bag. The vegetation is in sandbag bags.

(Example) Hereinafter, the present invention will be explained based on an example shown in the drawings. Fig. 1 shows a slope on which a large number of vegetation sandbag bags (10) according to the present invention are arranged. On this slope,
A framework is formed by combining many synthetic resin slope frames, etc.
Within this framework, the seeds (13) and fertilizers (14) described below
Alternatively, the construction is carried out by directly placing a plurality (6 to 8 bags in this embodiment) of vegetation sandbags (10) with the soil conditioner, plant growth material, etc. facing upward.

The vegetation sandbag bag (10) mainly consists of a coarse mesh bag (11), and as shown in Figures 3 and 4, the negative side of the net bag (11) (a special A water-soluble film (12) is attached to the inside of the seed (
13) and fertilizer (14), or a soil conditioner and plant growth material, etc. are sandwiched between them.

The mesh bag (11) is made of a corrosion-resistant synthetic resin material in this embodiment, but natural fibers or the like may be used if necessary, and the mesh bag (11) is coarse enough to prevent the soil contained therein from leaking out. have. The specific material of this net bag (11) in this embodiment is polyethylene. Moreover, as the water-soluble film (12), a film containing polyvinyl alcohol as a main component and having a thickness of 0.017 to 0.05 mm is used. This polyvinyl alcohol is widely used as a glue for leather, paper, etc., and is also widely used as an adhesive that can be peeled off again when wetted with water. The most suitable polyvinyl alcohol is one with a saponification degree of 86 to 88%, which has the highest water solubility. If the saponification degree is about 40 to 50%, it is used. This means that when the seeds (13) and fertilizer (14) are porous, when the water-soluble film (12) is dissolved by water, the seeds (13) and fertilizer (14) or soil improvement This is to ensure that the water-soluble film (12) functions as an adhesive by adhering to adhesives, plant growing materials, and the like.

The type of seeds (13) should be selected in consideration of the protection of the slope, and the fertilizer (14), soil conditioner, plant growth material, etc. should be selected to be suitable for these selected seeds (13). used.

In addition, in the vegetation sandbag bag (lO) of this embodiment, as shown in FIG. 2, only the upper end shown in the figure is open, and the other edges are sealed by fastening or the like. Further, a string (15) is provided at the opening of the vegetation sandbag bag (10), and the opening can be sealed by tightening the string (15). Alternatively, the vegetation sandbag bag (10) can be sealed by folding back the opening of the vegetation sandbag bag (10) and hanging it on a hook or button (not shown) attached to a part of the bag (10). There is.

Next, the vegetation sandbag bags (10) constructed as described above are sequentially conveyed by a conveyor, and a continuous sheet-like water-soluble film (12) is placed on the net bags (11). The water-soluble film (12) is transported sequentially and laminated and bonded to each other.Before this water-soluble film (12) is transported onto the net bag (11), the water-soluble film (12) is first transported onto the net bag (11).
2) The upper surface is wetted by spraying water with a sprinkler (22). Seeds (13) and fertilizer (14) are further scattered onto this moistened water-soluble film (12) by spreaders (23) and (24). In this case, if necessary, in addition to the seeds (13) and fertilizer (14), soil conditioners, plant growth materials, etc. may be added and scattered using a spreader. The scattered seeds (13) and fertilizer (14) adhere to the water-soluble film (12) because the surface of the water-soluble film (12) is dissolved by water and serves as an adhesive.

As described above, the water-soluble film (12) is placed on the net bag (11).
) is laminated, the dissolved portion of the water-soluble film (12) has not yet dried, and this also serves as an adhesive between the water-soluble film (12) and the net bag (11). Therefore,
The seeds (13) and the fertilizer (14) are covered with a water-soluble film (12).
), and the water-soluble film (12) is adhered to the net bag (11) by laminating it thereon. If this state is passed through the dryer (25), the dissolved water-soluble film (12) will dry and solidify, and each seed (13) and fertilizer (14) will be transferred to the net bag (11) and the water-soluble film (12). The adhesive film (12) is sandwiched and adhered to the adhesive film (12).

After that, a water-soluble film (
12) and turn over the net bag (11) so that the water-soluble film (12) is inside, it becomes a bag for vegetation sandbags (lO).
completed as. Note that if the intervals between the mesh bags (11) are sequentially widened before being carried into the dryer (25), each water-soluble film (12) is in a semi-dissolved state and can be easily cut. The process can be omitted.

FIG. 6 shows a second method for manufacturing the vegetation sandbag (10). In this second method, a continuous sheet-like water-soluble film (12) is sequentially conveyed horizontally on a conveyor, and a water sprinkler (22) is placed on the conveyed water-soluble film (12). Alternatively, water or an adhesive solution is sprayed by an adhesive spraying device (26) to be described later.

Next, the seeds (13) and fertilizer (14) are spread onto the water-soluble film (12) by the spreader (23) (20).Then, the net bag (11) formed as a heavy bag is sequentially spread over the water-soluble film (12). ).The subsequent steps are the same as the first method.Compared to the first method, the water-soluble film (12) is always positioned horizontally in this second method. , damage to the water-soluble film (12) can be minimized.

Further, FIG. 7 shows a third method for manufacturing a sandbag for vegetation (10). This third method is almost the same as the second method, but a net bag (11) formed as a vehicle
Instead of supplying one continuous mesh bag base material one after another, one continuous coarse mesh bag base material is supplied one after another. And the dryer (25)
After drying, the sandbag bag (10) for vegetation is completed by cutting and sewing it into a predetermined shape.

In addition, in any of the above methods, drying in the dryer (25) takes into account the negative effect on the seeds (13).
The temperature should be such that the seeds (13) do not wither.

Further, instead of the water sprinkler (22) in the above-described process, an adhesive spraying device (28) for spraying an adhesive solution may be provided. This produced a sandbag for vegetation (1O) according to the second invention. As this adhesive, vinyl acetate and acrylic copolymer are used.

Then, a water-soluble film (12
) and the net bag (11) are laminated, so that the seeds (13) are sandwiched between the water-soluble film (12) and the net bag (11).

When this is passed through the dryer (25) and dried, one seed (13) is glued between the water-soluble film (12) and the mesh bag (11) by the adhesive on the water-soluble film (12) side. Being pinched. Note that if an aqueous solution is used as the adhesive solution, the water in which the adhesive is dissolved will partially dissolve the water-soluble film, and the water-soluble film itself will also dissolve in the adhesive, as in the case of the first invention. As a result, compared to the case described in 1, the net bag (11) of the seed (13)
Moreover, adhesive sandwiching between the water-soluble films (12) can be performed more reliably. In addition, seeds (13)
Adhesive sandwiching between the net bag (11) and the water-soluble film (12) is achieved by spraying water on the top surface of the water-soluble film (12) with a sprinkler (22) and at the same time Net bags (1
1) The above-mentioned adhesive may be sprinkled on the surface in advance. In this case, a water-soluble film (12
) It is necessary to securely attach the seeds (13) etc. to the upper surface of the container in advance. In addition, after spraying adhesive on the net bag (11), seeds (13) etc. are glued thereto, and the net bag (11) is
It may be carried out by pressing a water-soluble film (12) on top (Effect) The vegetation sandbag bag (10) constructed as described above is prepared by filling soil into the bag (10) for each seed (13). ) and fertilizers (14)
, or the soil conditioner, plant growing material, and the like are placed upward within the frame of the slope shown in FIG.

During this work of adding soil, each seed (13), fertilizer (14), soil conditioner, plant growth material, etc. is adhesively sandwiched between the net bag (11) and the water-soluble film (12). There is no misalignment in the lower part of the net bag (1'l), that is, in the soil. This is because the water-soluble film (12) is attached to the net bag (11).6 Also, when it rains, the water-soluble film (12) dissolves and disappears completely. Therefore, each seed (!3) can lie directly on the surface of the seedlings and germinate very easily. In addition, the seeds (13) and fertilizers (14), soil conditioners, plant growth materials, etc. can be definitely located on the surface of the soil, and the roots of the seeds (13) can definitely spread into the soil. can. (Achievement of objective ■) In this vegetation sandbag bag (1o), each seed (13)
and fertilizers (14), soil conditioners, plant growth materials, etc., are adhesively sandwiched between the net bag (11) and the water-soluble film (12), so that these seeds can be removed during transportation or construction work. (13), fertilizer (14), soil conditioner, plant growth material, etc. will not fall off. In particular, in this bag for vegetation sandbags (10), seeds (13) and fertilizers (14), soil conditioners, plant growth materials, etc. are stored in the net bag (11) and the water-soluble film (1).
This effect is sufficient because the structure is not simply sandwiched between 2) but also bonded. (Achievement of Objective (2)) Moreover, this bag for vegetation sandbags (10) can be easily formed using conventional materials and devices that generally exist on the market. As mentioned above, it has a structure that prevents seeds (13) etc. from falling off as much as possible, so relatively expensive seeds (13) can be used efficiently. (10) The cost can be reduced.

(Achievement of objective (2)) Furthermore, as in the first invention, if the adhesive action of the adhesive and the adhesive action of the water-soluble film (12) itself are used together, the net bag (11) and Water-soluble film (
12) can be ensured, and the adhesive and sandwiching of seeds and fertilizer can be made more reliable. (Achievement of objective ①) Also, since the adhesion of seeds (X3), etc. to the net bag (11) and the water-soluble film (12) is achieved through the cooperation of the adhesive and the water-soluble film (12), only the adhesive can be used. The use of adhesive can be reduced compared to when adhesives are used, and there is no possibility that the adhesive will coat the seeds and prevent them from germinating.

In addition, in this example, the net bag (1
1) is made of coarse synthetic resin such as polyethylene, so the sandbag itself will not corrode at least until the slope is stabilized. (Achievement of objective 1) (Summary) As detailed above, in the present invention, as exemplified in the above embodiment, a coarse mesh bag and a water-soluble A bag for vegetation sandbags comprising a film, and seeds, fertilizers, soil conditioners, plant growth materials, etc. sandwiched between the water-soluble film and the net bag, wherein the water-soluble film is surface-dissolved by water. The feature is that the water-soluble film and the net bag are bonded together, and the seeds, fertilizers, etc. are bonded and sandwiched between the water-soluble film and the net bag. It is possible to provide a sandbag for vegetation that has a configuration that allows germination, is low in cost, and prevents seeds from easily falling off during transportation, placement work, etc.

Further, the feature lies in that the adhesive sandwiching between the water-soluble film such as seeds and fertilizers and the net bag is carried out by adhering the adhesive to the water-soluble film or the net bag and drying and solidifying the adhesive. As a result, it is possible to provide a sandbag for vegetation in which seeds and fertilizers can be adhesively and clamped to the water-soluble film and the net bag even more reliably.
