DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope greening method.

[0002]

2. Description of the Related Art As one of slope revegetation methods, there is a method in which seeds of an exotic plant such as grass are mixed with seeds of a native plant such as a flower plant, a wild grass or a tree on the slope. However, in this method, the growth of the grass is strong, and the flower plants, wild grass, and trees are pressed by the grass, and the flower plants, wild grass,
Without trees growing, only the grass becomes green, and the final goal, the slope, cannot be restored to the mountain.

Therefore, for example, Japanese Utility Model Application Laid-Open No. 60-114607.
As shown in the publication, while the grass seeds are accommodated in a bag made of a soluble film together with fertilizer, flower plant seeds, wild grass seeds, tree seeds are provided in a turf section made of a net or the like,
A grass vegetation-like vegetation substrate has been proposed in which grass is separated from flower plants, wild plants, and trees to prevent the grass from compressing the flower plants, wild plants, and trees.

[0004]

However, in the turf-like vegetation substrate described in the above-mentioned publication, the bag containing the grass seeds and the fertilizer is made of a soluble film. In spite of seeds and fertilizer spills, the pastures grow in the turf section and grow there. , Wild grass, and trees were sometimes squeezed.

On the other hand, as an improvement of the technique described in the above-mentioned publication, it is conceivable to store grass seeds and fertilizer in a bag made of nonwoven fabric. Considering the difficulty of tearing, if the bag is too strong, there is a problem that grass seeds cannot germinate.

There is also the following problem. That is,
The net used as the base in the above-mentioned turf section is conventionally made of a chemically synthesized plastic such as polyethylene (PE) or polypropylene (PP), and this plastic is permanently changed under normal conditions. Therefore, unlike other plant-based materials and animal-based materials, they are not exposed to the weather and weathered or corroded for many months, and are not homogenized with soil or soil. For this reason, in recent years, such characteristics have been regarded as evil and have become a global environmental problem as plastic pollution.

Therefore, in such a situation, the use of a net made of plastic in a slope greening method or the like contributes to environmental greening on the one hand, but also promotes plastic pollution on the other hand. It becomes.

In order to avoid the above-mentioned problems caused by the characteristics of plastic materials, nets made of vegetable materials such as jute have been used in some cases. Viscose rayon is made of regenerated cellulose and is a so-called corrosive material that completely corrodes even after a relatively short period of time, and can be applied to a loom relatively easily. -82
As proposed in Japanese Patent Publication No. 8 (KOKAI) No. 8, an attempt has been made to use it in a case where the net is partially corroded. Further, in addition to viscose rayon, a net using a biodegradable plastic as a corrosive material has been proposed, for example, in Japanese Utility Model Laid-Open No. 3-5746.

As described above, in order to corrode the net, it has been proposed to construct the net using various corrosive materials, but these have not been used so often in the past. The reason is as follows. That is, when a corrosive net is laid on a slope, most of these nets are corroded about two months after laying on the slope, and the required strength is lost. The period, such as two months, is too short for the plants to germinate from the vegetation material provided in the net and grow and prosper sufficiently, thus achieving the original objectives of net slope protection and plant growth. Can not do it.

[0010] Therefore, an ideal net for use in slope protection is to maintain mechanical strength such as sufficient tensile strength in the latter half to two years of laying, and to finish the plant after the plant has grown to some extent. It can be said that they are corroded and homogenized in the soil. In this case, when a housing portion or the like is formed in the net body and a fertilizer bag or the like is housed in the housing portion, it is desirable that the bag such as the fertilizer bag is also made of a soluble material.

The present invention has been made in consideration of the above-mentioned matters, and an object of the present invention is to protect a slope by vegetation without losing pressure on alien plants such as grass. Native plants such as plants, wildflowers, and trees can be germinated and grown without fail, and the slopes can be protected by nets with high tensile strength until these vegetation are fully grown and prosperous. Nevertheless,
When vegetation has achieved the protection of the greening of the slope, the goal is to propose a slope greening method in which the net is decomposed and corroded to homogenize with the soil.

[0012]

In order to achieve the above object, according to the first invention, a corrosive material which has been subjected to an antibacterial treatment to such an extent that the necessary strength is maintained for about half a year to two years after laying.

[0018]

In any of the above-mentioned inventions, the members such as the warp and the weft constituting the net are made of a corrosive material which has been subjected to an antibacterial treatment. The vegetation substrate made of such a material is described in Table 1 below. As shown in Table 2, the tensile strength is higher than that of corrosive materials such as viscose rayon, cotton yarn, and hemp yarn, which are conventionally used. There is as much as 80%. Therefore,
The reticulated body can sufficiently function as a reticulated body if the tensile strength of the fiber (material) constituting the reticulated body is 0.6 kg / strand or more. The reticulated body made of a conductive material can maintain the required strength for about half a year to two years after laying, and protect the slope.

As described above, the reticulated body made of the corrosive material subjected to the antibacterial treatment gradually decreases its strength, and is corroded when the plants grow and prosper on the slope, and finally returned to the soil. .

[0020] The accommodating portion and formed between the nets, and partially formed double portion, a bag support portion formed on the mesh surface, for example flower plant, grass, seeds, such as trees Together with an appropriate fertilizer, for example, a vegetation bag is housed or provided in a bag formed by laminating a net made of rayon and water-soluble paper, so if this is laid on the slope, At first, the vegetation seeds in the vegetation bag do not flow out because they are covered with the water-soluble paper.

For example, when there is rainfall, the water-soluble paper is rapidly dissolved by the raindrops, so that the vegetation seeds can easily germinate. In this case, the movement of the vegetation seeds is prevented by the net made of rayon, so that the seedlings germinated from the vegetation seeds do not come out of the vegetation bag, and can be reliably grown by receiving the supply of fertilizer and moisture. .
Among the members constituting the bag, the water-soluble paper easily dissolves, and the net is corroded when the plant grows and proliferates on the slope, and eventually returns to the soil.

In FIG. 1, reference numerals 14 and 15 denote fertilizer bags and vegetation bags which are appropriately stored and held in the storage section 9. The fertilizer bag 14 is formed using a soluble material such as a swoof-based nonwoven fabric, a pulp-based nonwoven fabric, a soluble paper, or a biodegradable plastic so that the fertilizer nut has a thickness and air permeability such that the fertilizer nutrients gradually leak due to rainfall or the like. In the bag, a fertilizer, a soil conditioner, a water retention agent, and other fertilizer base materials necessary for growing a plant directly or indirectly are contained.

As shown in FIG. 4, the vegetation bag 15 is made of ordinary rayon and has a mesh size of 3 to 5 mm and does not hinder the germination and growth of the vegetation. Grass seeds or flowers are placed in a bag 18 formed by laminating a soluble paper 17 made of non-woven paper such as Bonric (trade name of Venus Paper Co., Ltd.) with the net 16 facing outward. It contains vegetation seeds 19 such as plant seeds, wild grass seeds, and tree seeds.

As the material of the net 16, besides ordinary rayon, cotton or a soluble material obtained by blending rayon and cotton can be used. Further, as the soluble sheet 17, a polymer-based or starch-based soluble (herein, also including a so-called semi-soluble) film, a staple nonwoven fabric, a pulp nonwoven fabric, or the like is used, or is gradually dissolved by moisture. 40 pulp with polypropylene

And, as flower plant seeds, there are yellow daisy, French chrysanthemum, large gold chicken chrysanthemum, saw, grass flycatcher, California poppy, murasakihana, gypsophila, cosmos, celosia, kawaranadeshiko, daisies, etc. , silver grass, Medohagi, there is such as Japanese knotweed, further, as the tree seed,
There are red pine, yabu-shabu, weasegi, yamahagi, komatsunai, etc. These may be appropriately selected and stored in the bag 18. Note that a water retention material and some fertilizer may be stored in each of the vegetation bags 18.

The vegetation base 1 in this embodiment is provided with a fertilizer bag 14 and a vegetation bag 1 in a storage portion 9 formed in the net 2.
5 is appropriately housed, but in order to green the entire slope with alien and native plants in good balance,
It is important to appropriately select the type of the vegetation bag 15 to be accommodated in the accommodating portion 9 and the type of the vegetative seed 12 to be pre-attached and sowed to the thin cotton wool 10 stuck on the upper surface of the back net 4 and to combine these well. is there.

[0032] Therefore, as shown in FIG. 5, the housing portion 9 of the vegetation substrate 1 one Tsuo to Kino housing portion 9a, a fertilizer bag 14, annual flowers seeds, flowers such as perennial flowers seeds A vegetation bag 15h containing a vegetation bag 15h in which plant seeds , wild grass seeds, and tree seeds are appropriately mixed, and containing grass seeds in a storage portion 9b sandwiched between the storage portions 9a.
And grass seeds, flower plant seeds , etc.
Wild grass seeds or tree seeds are housed separately.

Here, the annual flower plants include California poppy, purple hana, gypsophila, cosmos, and kato, and the perennial flower plants include Kawaranadeshiko, Teningiku, Yarrow, French chrysanthemum, and large golden chicken chrysanthemum.

Here, the net 2 will be described in more detail. First, as the corrosive material, various materials such as animal, vegetable, and chemical can be used. For example, natural fibers such as skin, wool, cotton, hemp, and pulp are representative examples of animal and vegetable materials. It is a target. Examples of the chemical material include a biodegradable plastic and a photo-decomposable plastic, in addition to a polyolefin-based material which is easily corroded by a chemical and a recycled fiber such as viscose rayon. Examples of the biodegradable plastic include, for example, Tone (US AM
KO), brand name Pullulan (manufactured by Hayashibara Co., Ltd.), and brand name Sore Phil (manufactured by Mitsubishi Rayon Co., Ltd.). The photodegradable plastics include, for example, Polygrade (trade name, manufactured by Ambass USA) and Plastigone (trade name, manufactured by Idea Masters Co., Ltd.).

Examples of the antibacterial agent used in the antibacterial treatment include lauryldimethylbenzylammonium chloride whose active ingredient is dimethylbenzylammonium chloride (for example, “Meirapit V-43” (trade name) of Meisei Chemical Industry Co., Ltd.) and octadecyl. dimethyl benzyl ammonium chloride [e.g. "Meikabinon SMB-85" of Meisei chemical industry Co., Ltd. (trade name)] and the like.

Next, viscose rayon fiber was used as a corrosive material, and "Meirapit V-43" was used as an antibacterial agent.
A method of performing an antibacterial treatment using is described with reference to FIG. In this figure, 41 is a known viscose rayon manufacturing apparatus, 42 is a dryer, 43 is an antibacterial treatment tank containing a 5% solution 44 of “Meirapit V-43”,
45 is a squeezing roller pair, 46 is a dryer, 47 is a curing device, and 48 is a winding device.

In the apparatus configured as described above, for example, 2
The 2,000 denier viscose rayon fiber 49 is pre-dried at an appropriate temperature in the dryer 42. The pre-dried viscose rayon 49 is immersed in the solution 44 of “Meirapit V-43” in the antibacterial treatment tank 43. At this time, the solution 4 of “Meilapit V-43”, which is an antibacterial agent,
4 is adsorbed on the viscose rayon 49. Next, the viscose rayon 49 into which the solution 44 is immersed is appropriately squeezed by the squeezing roller pair 45, reaches the dryer 46, and undergoes a predetermined drying process. Then, the viscose rayon 49 that has been subjected to the drying process is, for example, at 150 ° C. for 3 minutes or 17 ° C. in the curing device 47.
After being subjected to a curing treatment at 0 ° C. for 1 minute, the film is wound by a winding device 48. When the viscose rayon 49 is immersed in the solution 44 of “Meirapit V-43” in the antibacterial treatment tank 43, the adsorption amount of the solution 44 becomes 0.2 g.
/ M so that the viscose rayon 49 is sent.

Then, the present inventors sow seeds and fertilizer appropriately selected from the plant seeds in a flat field in April,
An antibacterial corrosive material and an untreated corrosive material were laid thereon, and the tensile strength of the fiber after the laying was examined. The data shown in Tables 1 and 2 were obtained. The sample used in this test was a set of 2000 denier viscose rayon fiber and 900 denier cotton yarn, each of which was adsorbed with a 5% solution of “Meila Pit V-43” at 0.2 g / m. A corrosive material subjected to an antibacterial treatment and a corrosive material not subjected to this treatment.

[0039]

[Table 1]

[0040]

[Table 2]

According to the above two tables, the corrosive fiber subjected to the antibacterial treatment maintains a tensile strength of 1.5 kg / piece even after 6 months from the laying, and the fiber is covered by vegetation. It has maintained considerable strength even after months. On the other hand, the corrosive fiber which has not been subjected to the antibacterial treatment,
Three months later, corrosion by microorganisms and the like progressed, and natural cutting of the fibers began to be seen. Six months after the installation, the fibers completely assimilated with the soil.

Incidentally, the antibacterial treatment of a corrosive material such as viscose rayon is not limited to that shown in FIG. 12, but may be configured as shown in FIG. 13, for example. That is, in this figure, the viscose rayon 49 fed out of the viscose rayon manufacturing device (not shown) is passed through the antibacterial agent coating device 50,
The surface is coated with an antibacterial agent, and then dried by a dryer 51. After a predetermined curing is performed by a curing device (not shown), the film is wound by a winding device 52.

The net 2 may be formed by using a material before being applied to a loom, that is, a material which has been subjected to an antibacterial treatment in a stage such as a monofilament or a flat yarn, and then applying the antibacterial treatment to the loom. Alternatively, after weaving the mesh 2 having a predetermined shape using a monofilament or flat yarn, the mesh 2 may be immersed in an antibacterial agent, or the antibacterial agent may be applied by means such as showering or spraying. In addition, the concentration of the antibacterial agent used for these antibacterial treatments is not limited to the above-described example,
It has been confirmed by the inventor's test that the adjustment may be appropriately performed within the range of 10%.

When the warp yarns 5 and 6 and the weft yarns 7 and 8 are made of viscose rayon, 1.5% is added to the viscose solution.
% Of "Meirapit V-43" added and mixed (internal addition)
Then, an antibacterial treatment may be performed. In addition, the compounding ratio of the antibacterial agent may be 1 to 10%.

As shown in FIG. 6, the vegetation base 1 having the above-mentioned structure is fixed to the vegetation bag 15 by using the anchor 2 or the peg 21 so that the back net 4 side is close to the slope 22.
h is located above the fertilizer bag 14. In the net 1 laid on the slope 22, the vegetation seeds 19 in the vegetation bags 15 b and 15 h do not flow out because they are covered with the soluble sheet 17 at the beginning of the laying. Then, for example, when there is rainfall, the soluble film 17 is rapidly dissolved by the raindrops, so that the vegetation seeds 19 can easily germinate. In this case, since the movement of the vegetation seeds 19 is held by the net 16 made of rayon, the seedlings germinated from the vegetation seeds 19 can surely grow by receiving the supply of fertilizer and moisture.

In the vegetation base 1, the grass in the vegetation bag 15b accommodated in the accommodating portion 9b grows quickly and grows in a streak shape to protect the slope 22. And
Also in the other receiving portion 9a of the vegetation base 1, flower plant seeds
And germinates from wild plants and tree seeds. However, since it is away from the grass, it can grow without being subjected to the pressure. Moreover, since the fertilizer bag 14 is provided in the accommodation portion 9a, it can grow reliably. Therefore, the entire slope 22 is surely greened in a well-balanced manner.

The vegetation base 1 comprises the warp yarns 5 and 6 and the weft yarns 7 in the front net 3 and the back net 4.
8 is made of a corrosive material that has been subjected to antibacterial treatment. Therefore, when it is laid on the slope 22, the necessary strength is maintained for about two to two years after the laying, and the slope 22 is maintained. Can be protected.

In the vegetation substrate 1, the reticulated body 2 gradually decreases in strength as the plant grows and grows to some extent, and is decomposed and corroded to become tattered, and finally returned to the soil. . Further, since the fertilizer bag 14 housed in the housing part 9 is made of a soluble material such as a staple non-woven fabric, a pulp non-woven fabric, a soluble paper, a biodegradable plastic, etc., the plant germinates for a certain period of time (this grows to some extent). After that, it is decomposed and homogenized with the soil. Then, among the members constituting the bag 18 of the vegetation bag 15, the soluble sheet 17 easily dissolves and the net 1
6 also erodes when the plants grow and prosper on the slope 22 and finally return to the soil.

FIGS. 7 and 8 show an embodiment of the second invention. First, in FIG. 7, reference numeral 23 denotes a vegetation base, and its net 24 has both the fertilizer bags 14 and 15 or the fertilizer bags. A double part 25 is formed for accommodating 14.

The structure of the reticulated body 24 will be described with reference to FIG. 8 as well. A monofilament of about 2,000 denier made of a corrosive material subjected to an antibacterial treatment is used as the warp 26, and an antibacterial treatment is applied as the weft 27. Tape-like flat yarns of about 2000 to 3000 deniers made of a corrosive material are used.

Next, the manufacturing method will be described.
And the weft 27 are laid on a loom, and the weft interval is 3-9.
A single net 24 is knitted in a plain weave or an entangled weave with a large number of two or more warps 26 every 10 to 100 mm in the transverse direction as books / inch. In this case, if the width of the weft 27 is large, the number of driving per inch may be reduced, and if it is small, the number may be increased. Further, as the weft 27, a wide weft that is folded a plurality of times to have a narrow width may be used. If the light shielding rate of the mesh body 24 at the time of knitting is set to about 50%, the moisture state in the fertilizer bag 14 can be stabilized.

Next, an appropriate length in the vertical direction (for example, 20 to 80)
cm) and then the warp 2 forming the net 24
6 is released from the weft 27, and the released warp 26 'is provided with the same number (3 to 9 / inch) of wefts 27' as the reticulated body 24 (this weft 27 'is also a corrosive material subjected to antibacterial treatment). And knitting). After the portion 25 for separating the front and back sides is provided, for example, about 3 to 10 cm, it is returned to the single net-like body 24 again. By repeating this, a partial double mesh is completed, and
The vegetation substrate 23 is obtained by appropriately storing the fertilizer bag 14 and the vegetation bag 15.

FIGS. 9 and 10 show an embodiment of the third invention. First, in FIG. 9, reference numeral 28 denotes a vegetation base, and its mesh 29 has both the fertilizer bags 14 and 15 or the fertilizer bags. A bag bearing 30 for accommodating the bag 14 is formed.

The structure of the reticulated body 29 will be described with reference to FIG. 10 as well. A monofilament of about 2000 denier made of a corrosive material subjected to an antibacterial treatment as the warp 31 and an antibacterial treatment as the weft 32 are used. Flat yarns of about 2000 to 3000 denier made of corrosive material are used.

Next, the manufacturing method will be described.
1 and the weft 32 are respectively laid on a loom, and the single net-like body 29 is woven by plain weaving or entangled weaving. Then, when performing the above-described weaving, the warp 31 is arranged at appropriate intervals in the weft 32 direction.
While the warp 33 for the bag bearing portion (the warp 33 for the bag bearing portion is also made of a corrosive material subjected to antibacterial treatment) is knitted in the vertical direction so as to include the weft 32 , the weft 32 is arranged at every vertical interval. Then, a loop portion 34 is formed on the surface of the mesh body 29 so as to be able to communicate in the direction of the weft 32, and the bag bearing portion 30 is formed between the loop portion 32 and the mesh body 29.

In the mesh members 24 and 29 according to the second and third inventions as well, the fertilizer bag 14 and the vegetation bag 15 are appropriately arranged on the double part 25 and the bag bearing portion 30, respectively, and the same as in the first invention. Needless to say, the above-mentioned effects can be obtained.

As will be understood from the above description, the vegetation bases 1, 23, 28 of the present application have their nets 2, 24, 29
Can accommodate or support a fertilizer bag 14 and a vegetation bag 15 irrespective of whether it has a double structure or not, but the fertilizer bag 14 and the vegetation bag 15 when the vegetation bases 1, 23, 28 are laid on the slope 22. Is not limited to the arrangement shown in FIG. 5, but various arrangements can be considered.

FIG. 11 shows a fourth embodiment of the present invention .
Therefore, an example of the arrangement of the fertilizer bag 14, the vegetation bag 15, and the cotton wool is shown . In the example shown in FIG. 2A, a layer 36 of cotton wool sprinkled with seeds 35 of an annual flower plant is stuck to the reticulated body 2, while a fertilizer bag 14 and a perennial flower plant are accommodated in the accommodating portion 9a. The vegetation base 1 comprising the vegetation bag 15b accommodating the grass seeds in the accommodating portion 9b while accommodating the vegetation bag 15h accommodating the seeds of the vegetation, such that the layer 36 is close to the slope 22. Laying.

In the case shown in FIG. 3B, the layer 38 of the cotton wool on which the seeds 37 of the annual flowering plant and the perennial flowering plant are scattered and sown is adhered to the mesh 2 while the accommodation portion 9a
Fertilizer bag 14 and vegetation bag 15b containing grass seeds
And the vegetation substrate 1 in which the fertilizer bag 14 is accommodated in the accommodating portion 9b is laid such that the layer 38 is close to the slope 22.

In FIG. 11, it goes without saying that the net 24 according to the second invention or the net 29 according to the third invention may be used as the net.

In the above-described embodiment, the vegetation base 1 is merely laid on the slope 22. However, the vegetation base 1 is laid on the slope 22 from above the vegetation base 1 laid on the slope 22. May be sprayed. In this case, for example, only flower plant seeds may be provided as seeds on the vegetation substrate 1 side, and only tree seeds may be mixed into the sprayed vegetation substrate.

The spraying method may be a so-called dry method which does not use water in which seeds are simply mixed with an organic material, a chemical fertilizer, a soil conditioner, and a water retention agent.
It can also be used in a wet spraying method using a hydroseeder or gunki. Further, as a vegetation material to be sprayed, a material such as PM C material (a registered trademark of Jomo Ryokusan Kogyo Co., Ltd.) obtained by processing sludge into a vegetation material is used, and this is sprayed using a mini cleat pump. May be sprayed.

[0063]

As described above in detail, according to the slope revegetation method of the present invention, seeds and flower plants of alien species such as grasses,
Vegetable seeds such as seeds of native species such as wild grasses and trees can be reliably retained without migration or runoff, and their germination and growth can be performed smoothly.

[0064] That is, seed and flower plant exotics plants such as grass, wild grass, by arranging the separating the seed Local species plant such as a tree, without being squeezed alien species plants such grass, It is possible to surely germinate and grow native plants such as flower plants, wild grasses and trees, and to revegetate slopes and the like in a desirable state.

[0065] Further, according to the slope face greening method of the present invention,
After laying the vegetation substrate on the slope, for about half a year to two years, the mesh maintains the desired strength, and after the period elapses, it gradually decomposes and corrodes, so the slope is formed by the mesh. Erosion is prevented. And the reticulate body maintains its strength until the vegetation seeds in the vegetation bag germinate and various plants grow to some extent, so that the vegetation seeds and plants do not run off, Is greened over its entire surface.

A mesh body having maintained its strength for a certain period (about half a year to two years) after laying has its strength gradually reduced after the lapse of the certain period, is gradually decomposed and corroded, and becomes tattered. Finally, return to the soil. In addition, the fertilizer bags and the vegetation bags stored in the storage unit also gradually dissolve and return to the soil. Therefore, unlike conventional technology, greening can be promoted without promoting plastic pollution.

[0067] Incidentally, vegetation substrate used for slope greening method of the present invention is also applicable to other greening slope.
