Description

Detailed Description of the Invention

[0001] The present invention relates to a vegetation base for greening, which is used, for example, in greening work.

[0002]

2. Description of the Related Art Generally, on slopes of hillsides formed by road construction and land development, plants are vegetated and greened in order to protect them and preserve the scenery. By the way, the applicant of the present application has disclosed that, in Japanese Utility Model Publication No. 57-52204, Japanese Utility Model Publication No. 58-5709, and Japanese Patent Application Publication No. 61-179923, there is no need for large-scale equipment or complicated construction. Has applied for a greening vegetation substrate which can economically perform greening on the slope and the like by various construction means.

The vegetation base for greening has an accommodating portion formed in a net-like body, and an accommodating portion accommodates a vegetation bag containing an organic material, a water retaining material and a vegetation base material such as fertilizer.
You can directly attach and hold plant seeds, fertilizer, etc. on the net,
Alternatively, a tension lawn belt holding these plant seeds and fertilizers is attached, or a mat capable of germination and growth of plant seeds is attached to the reticulate body, and the plant seeds are adhered and held on this mat. is there. Then, by laying such a greening vegetation substrate on a construction target surface such as a slope, the seeds of the plant are germinated to green the slope.

By the way, all the net-like members used for the greening vegetation substrate are made of plastic fibers such as nylon, polyethylene and polypropylene. This is because these plastic fibers are sturdy and inexpensive, in order to green the slope etc., the plant roots on this slope, maintaining the strength of the reticulate body until this plant grows to some extent, This is because it is necessary to protect the slope with a net and the net serves as a vegetation base for plants.

However, the above-mentioned plastic fibers have the property that they do not deteriorate semipermanently under normal conditions, and therefore, unlike other animal and plant fibers, they are exposed to wind and rain over the years to weather or corrode to soil. The reticulate body remains semi-permanently without being homogenized. Therefore, recently, the above characteristics are rather a disaster,
It has become a global environmental problem as plastic pollution. In other words, under the above circumstances, it is a contradiction that using a mesh made of plastic fibers for greening slopes, etc. contributes to environmental greening on the one hand, but causes pollution problems on the other hand. Will be done.

Therefore, in order to solve such a problem, it has been attempted to use a reticulated body made of vegetable fiber such as jute, and viscose rayon is made of regenerated cellulose, so that a long time has passed. It is a so-called corrosive fiber that is completely corroded even if it is not, and since it can be applied to a loom relatively easily, this viscose rayon is disclosed, for example, in Japanese Utility Model Publication No. 63-828. Attempts have been made to use it in the case where the mesh is partially corroded.

[0007]

However, as described above, when vegetable fibers such as jute or viscose rayon are used as the constituent material of the reticulate body, the following problems occur. That is, an ideal mesh-like body used for greening slopes is about half a year to 1 year after its construction.
It is desirable to maintain sufficient tensile strength for about a year and to corrode and homogenize with the soil after the plant has grown to a certain degree, but any of the reticulate bodies made of plant fibers or viscose rayon is a method. Almost two months after laying on the surface, etc., most of them will be corroded and the vegetation base strength necessary for vegetation will not be obtained. In other words, by the time the plants germinate and grow sufficiently, The period of two months was too short, and it was not possible to achieve the original purpose of securing the vegetation base of plants by protecting the slopes with a net-like body.

The present invention has been made with the above matters in mind, and the purpose of the present invention is, for example, in the latter half of the laying period.
For a period of about one year, it retains sufficient tensile strength as a reticulate body, and after that period, most of the constituent materials decompose and corrode and become homogenous with the soil, without causing pollution problems and environmental greening. Another object of the present invention is to provide a vegetation substrate for greening that can contribute to

[0009]

In order to achieve the above object, the present invention adopts the following configuration.
In the first aspect of the present invention, a vegetation bag body containing a vegetation material in a bag is attached to a reticulated body, and the reticulated body is made of strong rayon in a greening vegetation substrate formed by adhering and holding plant seeds to the reticulated body. I am configuring.

In the second aspect of the present invention, a vegetation bag body in which a vegetation material is housed in a bag is attached to a mesh body, and a vegetation base for greening is formed by attaching a stretch grass body holding plant seeds to the mesh body. In, the reticulate body is made of strong rayon.

In the third invention, a vegetation bag body containing vegetation material in a bag is attached to a net-like body, and a mat capable of germination and growth of plant seeds is attached to the net-like body, and the plant is placed on the mat. In a vegetation base for greening in which seeds are adhered and held, the mesh is made of strong rayon.

According to a fourth aspect of the present invention, a vegetation bag for vegetation containing a vegetation material in a bag is attached to a reticulated body, and the reticulated body is a vegetation base for greening, in which plant seeds are attached and retained. It is made of antiseptic corrosive material.

In the fifth aspect of the present invention, a vegetation bag body in which a vegetation material is housed in a bag is attached to a mesh body, and a vegetation base material for greening is formed by attaching a stretch lawn body holding plant seeds to the mesh body. In the above, the reticulate body is made of an antiseptic corrosive material.

In a sixth aspect of the present invention, a vegetation bag body containing vegetation material in a bag is attached to a net-like body, and a mat capable of germinating and growing plant seeds is attached to the net-like body, and the plant is placed on the mat. In a vegetation base for greening in which seeds are adhered and retained, the net-like body is composed of a corrosive material that has been subjected to an antiseptic treatment.

[0015]

In the first aspect of the present invention, the reticulate body, which is the main material of the vegetation base for greening, is made of strong rayon such as polynosic rayon and viscose rayon for tire cord. Mechanical strength, such as tensile strength, is higher than that of ordinary materials such as viscose rayon and biodegradable plastics used. For example, the tensile strength of polynosic rayon is
It is 3.4 g / D or more, and that of viscose rayon for tire cord is 3.0 g / D or more.

The high-strength rayon has such characteristics that the strength decreases little when wet and the strength decreases with the passage of time. In addition, the net-like body made of this strong rayon has a tensile strength of about 90% of the initial value even after the half year of construction. Therefore, the vegetation base for greening, which has a net-like body made of strong rayon having such characteristics, maintains the required strength and protects the slope for the second half to two years after being laid on the slope of the hillside. As a result, the vegetation base of the plant can be secured, and the plant seeds attached and retained on the reticulate body can be well grown.

As described above, high-strength rayon has a higher tensile strength than ordinary materials such as viscose rayon and biodegradable plastics, but since it is a cellulosic material, its strength gradually decreases, When plant seeds vegetated on slopes germinate and grow, they are decomposed and decomposed by microorganisms and become homogenized with soil. Therefore, it is possible to contribute to the greening of the environment without causing the pollution problem by leaving the whole mesh body semipermanently on the slope or the like.

In the second invention, as in the case of the first invention, the reticulate body which is the main material of the greening vegetation substrate is made of strong rayon such as polynosic rayon or viscose rayon for tire cord. Therefore, the required strength can be maintained for a certain period of time, the slopes, etc. can be protected with a mesh body to secure the vegetation base of the plant, and the plant seeds on the tension grass body attached to the mesh body can be well grown. . In addition, when the plant seeds on the turf are germinating and growing, the reticulate body is decomposed and corroded and homogenized with the soil. Therefore, it can contribute to environmental greening without causing pollution problems. .

In the third invention, as in the case of the first invention, the reticulate body, which is the main material of the greening vegetation substrate, is made of strong rayon such as polynosic rayon or viscose rayon for tire cord. Therefore, the required strength can be maintained for a certain period of time, the slopes, etc. can be protected with a mesh to secure the plant vegetation base, and the plant seeds on the mat anchored to the mesh can be satisfactorily grown. . In addition, when the plant seeds on the mat germinate and grow, the reticulate body is decomposed and corroded and homogenized with the soil. Therefore, it can contribute to environmental greening without causing pollution problems. .

In the fourth aspect of the invention, since the net body which is the main material of the vegetation base for greening is composed of the corrosive material which has been subjected to the antiseptic treatment, compared with the net body which is made of only the corrosive material, the latter half of the laying It has the necessary strength for about 1 to 2 years, and is about the same strength as the strong rayon. Corrosion begins as the effect of the antiseptic treatment weakens or disappears, and when the plant seeds vegetated on the slopes germinate and grow, they are decomposed and corroded by microorganisms and become homogenized with the soil.
Therefore, it is possible to contribute to the greening of the environment without causing the pollution problem by leaving the whole mesh body semipermanently on the slope or the like.

In the fifth aspect of the invention, as in the case of the fourth aspect of the invention, since the reticulate body, which is the main material of the vegetation base for greening, is made of a corrosive material that has been subjected to an antiseptic treatment, it is reticulated for a certain period of time. The vegetation base of the plant can be secured by protecting the slopes with the body, and the plant seeds on the stretched grass body attached to the reticulate body can be well grown. Moreover, since the reticulate body is decomposed and corroded and homogenized with the soil when the plant seeds on the stretched grass are germinated and grown, it is possible to contribute to environmental greening without causing pollution problems.

In the sixth aspect of the invention, as in the case of the fourth aspect of the invention, the reticulate body, which is the main material of the vegetation base for greening, is composed of a corrosive material that has been subjected to an antiseptic treatment, so that the reticulate for a certain period of time. The vegetation base of the plant can be secured by protecting the slopes with the body, and the plant seeds on the mat anchored to the net can be well grown. Moreover, since the reticulate body is decomposed and corroded and homogenized with the soil when the plant seeds on the mat germinate and grow, it can contribute to environmental greening without causing pollution problems.

In any of the above inventions, the net-like body prevents erosion on the slope due to rainfall, snow melting, wind erosion, frost heave, etc., and vegetative seeds fixed to the vegetation substrate are germinated and grown. Slopes can be protected by greening within a few years.

[0024]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show a first embodiment of the present invention. First, in FIG. 1, N is a vegetation substrate for greening, and 1
Is a reticulate body which is the main material. The warp yarns 2 and the weft yarns 3 of the reticulate body 1 in this example use monofilaments made of polynosic rayon having a characteristic that the tensile strength is higher than that of ordinary viscose rayon, but the strength decreases with the passage of time. Depending on the Russell loom, width 1 m, length 5 m, mesh size 20 × 12
It is woven into the mesh body 1 of mm. A reinforcing rope (not shown) is often provided, but this reinforcing rope is also made of polynosic rayon.

On one surface of the mesh body 1,
As shown in an enlarged view in the figure, plant seeds 5 are adhered and held together with a fertilizer, a soil conditioner, etc. through a water-soluble sizing agent 4 such as polyvinyl alcohol (hereinafter referred to as PVA). In addition, the vegetation bag body 6 is attached to the other surface of the mesh body 1 at an appropriate interval (for example, 50 cm).

The vegetation bag 6 is used for growing plants such as fertilizers, water retention agents and soil conditioners in a bag 7 made of corrosive material such as staple fiber, pulp-based nonwoven fabric, soluble paper or biodegradable plastic film. The necessary vegetation material 8 is contained, and the composition of the vegetation material 8 is arbitrary. Then, in this embodiment, the vegetation bag body 6 is held so as to be parallel to the weft thread 3 so that a part of the warp thread 2 of the net-like body 1 is submerged. The vegetation bag body 6 may also have plant seeds mixed in the bag 7.

Vegetation substrate N for greening constructed as described above
As shown in FIG. 2, the plant seeds 5 are laid on a slope 9 such as a hillside so that the vegetation bag body 6 is parallel to the contour line. Both are fixed).

In the greening vegetation substrate N laid on the slope 9 in this manner, the net-like body 1 has a higher tensile strength than ordinary viscose rayon, but the strength decreases with the passage of time. Since it is made of polynosic rayon, which has the characteristics, it maintains the required strength for about two to two years after its installation. Therefore, the reticulate body 1 protects the slope 9 to secure the vegetation base of the plant, and the plant seeds 5 adhered and retained on the reticulate body 1 can be favorably grown. Then, the reticulate body 1 is decomposed and corroded over time by microorganisms, homogenized with the soil when the plant seeds 5 germinate and grow, and the constituent elements of the vegetation base N for greening are homogenized with the soil, and the reticulated body is reticulated. The whole body 1 can contribute to environmental greening without leaving the slope 9 semipermanently and causing pollution problems.

3 and 4 show a second embodiment of the present invention. The vegetation substrate N for greening in this embodiment does not directly attach and hold the plant seeds 5 to the reticulate body 1, but the reticulated body 1 in which the above-mentioned polynosic rayon is knitted and woven on the stretched grass body 10 holding the plant seeds 5. It is attached to one surface of the.

That is, as shown in an enlarged manner in FIG. 3, the plant seed 5 is fixed between the two soluble sheets 11 and 12 by using a water-soluble sizing agent 13 such as PVA together with a fertilizer, a soil conditioner and the like. The sandwiched grass body 10 is formed by sandwiching the
One of the soluble sheets 11 is attached to one surface of the mesh body 1 by using a water-soluble sizing agent 14. Soluble sheets 11 and 12 do not hinder the germination and growth of vegetation,
In addition, water-soluble paper with crepe paper, polymer film or starch film, or syrup that dissolves in water
and so on. In this example, the soluble sheet
12 may be omitted.

FIG. 4 shows a state in which the greening vegetation base N constructed as described above is laid on the slope 9. In this embodiment, as in the first embodiment, the reticulate body 1 which is the main material of the greening vegetation substrate N is formed by using polynosic rayon, so that the necessary strength is maintained for a certain period. The vegetation base of the plant can be secured by protecting the slope 9 with the reticulate body 1, and the plant seeds 5 on the stretched grass body 10 attached to the reticulate body 1 can be well grown. Also,
By the time the plant seeds 5 on the turf grass 10 germinate and grow, the reticulate body 1, the vegetation bag body 6 and the turf grass body 10 are decomposed and corroded and become homogenized with the soil, thus causing pollution problems. Instead, it can contribute to environmental greening.

5 and 6 show a third embodiment of the present invention. The vegetation substrate N for greening in this embodiment has a mat 15 capable of germination and growth of plant seeds 5 attached to one surface of a net-like body 1 formed by weaving the above polynosic rayon.
The plant seeds 5 are adhered and held on the mat 15.

That is, as shown in an enlarged manner in FIG. 5, a mat 15 made of a soluble material is attached to one surface of the mesh body 1 by using a water-soluble sizing agent 16, and the mesh body 1 of the mat 15 is attached. The plant seeds 5 are adhered and held on the surface opposite to the above, using a water-soluble sizing agent 17 such as PVA together with fertilizers and soil conditioners. Examples of the material of the mat 15 include soft cotton, soft nonwoven fabric, and pulp nonwoven fabric capable of germination and growth of the plant seed 5.

FIG. 6 shows a state in which the greening vegetation substrate N constructed as described above is laid on the slope 9. In this embodiment, similar to the first and second embodiments,
Since the reticulate body 1 which is the main material of the vegetation base material N for greening is formed by using polynosic rayon, it retains a required strength for a certain period of time, and the reticulate body 1 protects the slope 9 etc. The vegetation base can be secured, and the plant seeds 5 on the mat 15 attached to the reticulate body 1 can be favorably grown.
Also, when the plant seeds 5 on the mat 15 germinate and grow, the reticulate body 1, the vegetation bag body 6 and the mat 15 are decomposed and corroded and become homogenized with the soil, thus causing pollution problems. Without doing so, it can contribute to environmental greening.

In the above-mentioned first to third embodiments, strong rayon such as polynosic rayon or viscose rayon for tire cord is used as the constituent material of the mesh 1 in the greening vegetation substrate N. The present invention is not limited to this, and the materials such as the warp yarns 2 and the weft yarns 3 constituting the reticulated body 1 and the reinforcing rope are made of a corrosive material subjected to antiseptic treatment, and are made of the above-mentioned strong rayon. You may make it give the same effect as the mesh body 1. And as a means of antiseptic treatment, a water repellent,
There are adhesives, antifungal agents, antibacterial agents, antiseptics, etc. Hereinafter, this will be described in detail.

First, the corrosive material is animal-based,
There are various things such as plant and chemical, but for example animal,
As the plant material, natural fibers such as leather, hair, cotton, hemp, and pulp are typical. In addition to chemical materials, there are polyolefin-based materials that have been easily corroded by chemicals, recycled fibers such as viscose rayon, microbial degradable plastics, and photodegradable plastics. Examples of biodegradable plastics include trade name Tone (manufactured by AMKO, USA), trade name Pullulan (manufactured by Hayashibara Co., Ltd.), and trade name Thor Phil (manufactured by Mitsubishi Rayon Co., Ltd.). And
The photodegradable plastics include, for example, trade name Polygrad (manufactured by Anvas, USA) and trade name Plastigon (manufactured by Ideamasters, USA).

Next, of the corrosive material, the procedure for water repellent treatment of viscose rayon, which is a recycled fiber, will be described.
This will be described with reference to FIG. In this figure, 18 is a known viscose rayon manufacturing apparatus, 19 is a dryer, 20 is a water repellent treatment tank containing a water repellent agent 21, 22 is a pair of squeezing rollers, and 23
Is a dryer, 24 is a curing device, and 25 is a winding device. As the water repellent agent 21, for example, a 5 to 7% solution of Asahi Guard AG-710 or AG-730 (both manufactured by Asahi Glass Co., Ltd.) under the trade name can be used.

In the thus constructed apparatus, the viscose rayon 26 fed from the viscose rayon producing apparatus 18 is pre-dried at an appropriate temperature in the dryer 19. The pre-dried viscose rayon 26 has the water repellent 21 in the water repellent treatment tank 20 hidden therein. Next, water repellent 21
The viscose rayon 26, which was dipped in the
It is appropriately squeezed in 22 and reaches the dryer 23 to undergo a predetermined drying process. Then, the viscose rayon 26 that has been subjected to this drying process, in the curing device 24, for example,
After being cured at 150 ° C. for 3 minutes or 170 ° C. for 1 minute, it is wound by the winding device 25.

FIG. 9 shows the viscose rayon 27 which has been subjected to the water repellent treatment as described above. In FIG. 9 (A), the coating layer 28 made of the water repellent 21 is formed on the outer periphery of the viscose rayon 26. Are formed. Further, as shown in FIG. 2B, a coating layer 28 is formed on the outer circumference of the viscose rayon 26, and a permeation layer 29 in which the water repellent 21 is soaked from the surface is also formed over the entire circumference.

The water repellent treatment of a corrosive material such as viscose rayon is not limited to that shown in FIG. 7, and may be configured as shown in FIG. 8, for example. That is, in this figure, the viscose rayon 26 fed from the viscose rayon manufacturing device (not shown) is passed through the water repellent agent applying device 30 to apply the water repellent agent to the surface thereof, and then dried. After being dried by the machine 31, further subjected to predetermined curing by a curing device (not shown), it is wound by the winding device 32.

By any of the water repellent treatments shown in FIG. 7 or 8, the water repellent viscose rayon 27 as shown in FIGS. 9A and 9B can be obtained. Unlike the conventional viscose rayon 26, the course rayon 27 has little decrease in strength when wet, and has properties almost equivalent to those of the above-mentioned strong rayon. And
By knitting the viscose rayon 27 thus water-repellent with a Russell loom, for example, the mesh body 1 shown in FIGS. 1, 3 and 5 can be constructed, and the so-called water-repellent treatment is performed. A reticulate body can be obtained.

Further, the water-repellent reticulated body is, as in the above-mentioned embodiment, made of a material before being woven on the loom, that is, a material which has been water-repellently treated at the stage of monofilament or flat yarn. It may be woven on a loom to form a reticulated body, or it may be woven or woven into a reticulated body of a predetermined shape using a monofilament or flat yarn, and then immersed in a water repellent or showering or spraying the water repellent. You may apply using means, such as.

By the way, in order to examine the corrosion degree and the tensile strength of the water-repellent reticulated body, the following experiment was conducted. That is, two mesh-like bodies entwined and woven using strands of 2000 denier viscose rayon (tape shape) were prepared, and one of the mesh-like bodies was sprayed with Asahi Guard AG-710 as a water repellent. The other mesh-like body was untreated, and these were laid on a south-facing slope with a gradient of 10 minutes, and the degree of corrosion and tensile strength after laying were examined. Results were obtained.

[0044]

[Table 1]

From the above Table 1, it can be seen that the water-repellent reticulated body is hardly corroded even after half a year and the tensile strength is maintained at about 96% of the initial value. . Therefore, it is considered that the reticulated body has the same effect as the conventional reticulated body for about two years after the installation. In addition, in the above test, it is added that the net-like body was covered with vegetation half a year after the installation.

In the above-mentioned embodiment, the viscose rayon is subjected to the water repellent treatment, but the present invention is not limited to this, and the other corrosive materials mentioned above are treated to the water repellent treatment. It goes without saying that a net-like body may be formed or a water-repellent treatment may be applied to the net-like body made of these corrosive materials.

The water repellent 21 needs to be appropriately selected depending on the object to be treated, and when the object to be treated is a chemical fiber other than a cellulosic material, for example, trade name Asahi Guard AG-710 or AG-730 ( 3 to 5% solution such as Asahi Glass Co., Ltd.) may be used. In addition, a silicone-based, fluorine-based, or wax-based water repellent may be used.

As can be understood from the above description, the desired strength can be maintained within a predetermined period after laying by applying the water repellent treatment to the reticulated body made of the corrosive material.
The reticulate body is gradually decomposed and corroded after the lapse of the period, but it can be treated with an adhesive as a method for delaying the decomposition and corrosion of the reticulate body made of a corrosive material. As the adhesive used for this treatment, for example, acrylic resin type trade names Polysol A-403-2 and AT-13
No. 0, AP-6710 (both manufactured by Showa High Polymer Co., Ltd.) may be used, and these are diluted 2 to 3 times and applied to a mesh made of a corrosive material, or this mesh is diluted. It may be dipped in an adhesive.

By the way, the decomposition / corrosion of the reticulate body made of a corrosive material is caused by the presence of bacteria which decomposes / corrodes the corrosive material and the presence of water. Therefore, one or both of them are kept away from each other for a certain period of time. If you do
It is possible to delay the decomposition / corrosion of the mesh made of corrosive material for a certain period. Therefore, on the net-like body made of a corrosive material, the product name Benlate (manufactured by DuPont), the product name Topgin M (manufactured by Nippon Tanka Co., Ltd.), the product name Xiramon EX.
(Takeda Pharmaceutical Co., Ltd.) or the like may be coated with an antifungal agent, an antibacterial agent, an antiseptic agent or the like, or the reticulate body may be dipped in these chemicals.

In the above-mentioned embodiment, the vegetation bag body 6 is attached to the net-like body 1 so that the warp threads 2 of the net-like body 1 are hidden, but it may be arranged as shown in FIG. That is,
The vegetation bag body 6 may be attached to one surface of the net-like body 1 by binding it with a string 33. In this example,
Although the stretched grass body 10 is attached to the side where the vegetation bag body 6 is attached to the mesh body 1, the stretched grass body 10 may be attached to the side opposite to the side where the vegetation bag body 6 is attached. . In addition, the vegetation bag 6 is tied with a cord 33.
Needless to say, the method of attaching the reticulate body 1 to the reticulate body 1 by the above method may be applied to the greening vegetation substrate N shown in FIGS. 1 and 3.

The vegetation bag body 6 is attached to the net-like body by
You may make it as shown in FIG. That is, unlike the embodiment shown in FIGS. 1 to 6 and 10, the reticulated body 1 shown in this figure is formed as a so-called double net, and the front net 34 and the back net 35 are superposed on each other. The nets 34 and 35 are connected to each other by the rope 36 which also serves as a reinforcement, and the vegetation bag body 6 is inserted into the accommodating portion 37 formed by the rope 36, as shown in the enlarged view of FIG.
38 is a reinforcing rope.

As understood from the embodiments shown in FIGS. 10 and 11, the vegetation bag body 6 may be attached to the mesh body 1. Needless to say, the reticulate body 1 in these examples is formed using the strong rayon or the corrosive material subjected to antiseptic treatment.

[0053]

As described above, in the invention described in claims 1 to 3, since the net-like body which is the main material of the vegetation base for greening is formed by using strong rayon, it is used as a slope surface or the like. When laid, the reticulated body can maintain a desired strength within a predetermined period after being laid, and after that period, the erosion is gradually decomposed and corroded. To be prevented. And, the reticulate body maintains its strength until the vegetative seeds attached to the vegetation base germinate and grow, and the predetermined plant begins to grow, so the plant does not run away, The surface is greened over its entire surface. On the other hand, the reticulate body gradually decreases in strength, is gradually decomposed, and is corroded to become tattered, and finally is attributed to soil. Therefore, unlike conventional methods, it is possible to promote greening without promoting plastic pollution.

In Claims 4 to 6, since the net body, which is the main material of the vegetation base for greening, is formed by using the corrosive material subjected to the antiseptic treatment, the inventions described in Claims 1 to 3 are obtained. Similarly, the reticulated body can maintain a desired strength within a predetermined period after being laid, and after that period is gradually decomposed and corroded, so that the slope prevents the erosion by the reticulated body. It Therefore, also in these inventions, greening can be promoted without promoting plastic pollution. Can be promoted.
