Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vegetation bag used for protection of natural ground.

[0002]

2. Description of the Related Art Hitherto, as this type of vegetation bag, there has been a vegetation bag in which a sandbag provided with vegetation material is filled with soil.

[0003]

In the above structure, the opening of the vegetation bag is the entire upper end, and when the soil is put in, especially at the site, the entire upper end opens in a circular shape, so the soil is overfilled and the weight is The weight was around 25 kg, the weight was heavy, and the soil was biased to the lower part of the bag, making it difficult to carry and handle other things, and construction was also difficult.

[0004] Further, the net-like body constituting the above-mentioned vegetation bag is generally woven and woven with synthetic resin fibers, which are different from plant and animal materials and exposed to wind and rain over many years. There has been a problem that weathering or corrosion does not homogenize with vegetation materials and soil and deteriorates the growth and rooting of growing vegetation.

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) that completely corrodes even after a long period of time is used as a material. Alternatively, it has been proposed to construct a net body or a bag body by using a corrosive biodegradable plastic as a material. However, these materials do not corrode about two months after they are laid on the slope. The seeds in the vegetation bag germinate, and the period of two months is too short to grow and grow sufficiently,
The fact that the required tensile strength is lost during this period is fatal in terms of preventing the vegetation material from running away due to rainfall or frost heaving, and so it is the current situation.

[0006] From the above, as a material of the net-like body which constitutes the net-like body of the vegetation bag, the tensile strength of the vegetation bag installed on the slope is at least half a year and has a margin from the standpoint of protecting the slope and growing the plant. It is expected to be maintained for about two years, and after the plant has grown to a certain degree and grown, it eventually corrodes,
It can be said that it is ideal to have a condition for homogenization in soil.

The present invention has a uniform thickness, can prevent excessive soil filling, is easy to carry and handles, can be easily constructed, and has the above-mentioned ideal conditions. The purpose is to provide a vegetation bag constructed by.

[0008]

Means for Solving the Problems The first invention of the present application is a table,
In the state where the two nets on the back are polymerized, both sides and the lower end of the net are integrally joined to form a bag, and the nets on the front and back are vertically aligned at arbitrary intervals in the width direction. The bag is filled with a vegetation material by connecting with a plurality of connecting threads, and at least a part of the front or back net-like body is knitted with strong rayon.

Further, according to the second invention of the present application, both side portions and the lower end portion thereof are integrally joined in a state where the three mesh bodies of the front, back and middle are superposed, and further, at arbitrary intervals in the width direction,
The back and the intermediate net are connected by a plurality of connecting yarns in the longitudinal direction, and the bag portion formed by the front and the intermediate net is filled with vegetation material, and is formed by the back and the intermediate net. The bag portion is filled with the vegetation growth base material, and at least a part of the front or back net-like body is knitted with strong rayon.

In both the first and second inventions, strong rayon is used for at least a part of the reticulate body. Instead of this, an antiseptic corrosive material is used, or a corrosive material is used. It is also possible to knit and weave with the material and to subject the net-like body to preservative treatment.

[0011]

In the first aspect of the invention, the mesh bodies on the front and back sides are connected to the second mesh.
In the invention, since the back and the intermediate mesh body are connected by a plurality of connecting threads, the upper end opening does not open in a circular shape as in the conventional case, but it opens in a uniform width. It is possible to prevent uneven distribution of soil and bags containing soil that is more than necessary, easy to carry and handle, easy to construct, ensure greening, and grow vegetation materials and vegetation in factories. If the base material is filled, the weight can be reduced to a predetermined value and quality control can be easily performed.

The strong rayon (polynosic rayon and viscose rayon for tire cord) for forming the reticulated body selected in the first and second inventions has a higher tensile strength than general viscose rayon or biodegradable plastics. The strength is high, the decrease in strength when wet is small, and the tensile strength of about 90% of the initial value is maintained even after the lapse of half a year after laying, and then the strength decreases with the passage of time and eventually corrodes. Exhibits the property of homogenizing with soil, and the material exhibiting this property correctly fulfills the ideal conditions described above, and the tensile strength of polynosic rayon is 3.4 g /
The tensile strength of the viscose rayon for tire cord is 3.0 g / D or more.

In the third and fourth inventions, the constituent material of the reticulate body is made a corrosive material, and this is subjected to antiseptic treatment. Therefore, even if it is a corrosive material, by applying antiseptic treatment such as water repellency, water proofing, insect repellent (anti-mold, anti-bacterial, etc.), the material strength of the vegetation substrate can be laid in the second half or two years. The degree can be maintained sufficiently, and eventually corrosion will start as the effect of antiseptic treatment weakens or disappears, which will also become homogeneous with soil, and on the slope protection equivalent to the above-mentioned strong rayon. A vegetation bag with ideal conditions is constructed.

Holds a vegetation material (in this embodiment, so-called seed sheet in which seed and fertilizer are sandwiched between two pieces of crepe paper, and a suhu kaya is attached to the upper surface).

In addition, the bag portion 13 formed by the mesh bodies 2 and 11 between the back and the middle is filled with a vegetation growth base material 15 such as soil, bark, peat moss, vermiculite, and a soil conditioner. . When the vegetation material 14 and the vegetation growth base material 15 are housed and filled in the bag portions 12 and 13, respectively, as shown in FIG. 6, the intermediate mesh body 11 is positioned close to the mesh body 1 in the table. It has become.

In FIGS. 5 and 6, the same symbols as those shown in FIGS. 1 to 4 indicate the same items, and detailed description thereof will be omitted. Further, instead of the string-shaped body 7 in each of the above-mentioned embodiments,
As shown in FIGS. 7 and 8, a long core 16 may be used to seal the mouth of the bag 8 with a metal fitting 17 such as a wound stitch.

By the way, strong rayon such as polynosic rayon and viscose rayon is selected as a constituent material of the net-like bodies 1 and 2 of the vegetation bag according to each of the above-mentioned examples, but a corrosive one is selected as the constituent material. Select this corrosive material itself or a vegetation substrate composed of this corrosive material, and apply a water-repellent antiseptic treatment to it.
It can be used for greening protection of.

That is, the corrosion is caused by the presence of bacteria and water, and if the water repellent treatment is performed so that the water in the bacteria and water does not penetrate into the material of the vegetation bags 1 and 2, the progress of the corrosion can be delayed for a considerable period of time. it can. There are various corrosive materials targeted for this water repellent treatment such as animal, vegetable, and chemical. For example, animal material is leather or hair, and vegetable material is cotton or cotton. Typical examples are natural fibers such as hemp and pulp. Further, as the chemical material, there are a polyolefin-based material easily corroded by chemicals, recycled fiber such as viscose rayon, and other biodegradable plastics and photodegradable plastics.

Examples of the above-mentioned microbial-degradable plastics include trade name Tone (manufactured by AMKO, USA), trade name Pullulan (manufactured by Hayashibara Co., Ltd.), trade name Thor Phil (manufactured by Mitsubishi Rayon Co., Ltd.) and the like. The photodegradable plastics include, for example, trade name Polygrad (manufactured by Anvas, USA) and trade name Plastigon (manufactured by Ideamasters, USA).

The vegetative bags 1 and 2 are obtained by subjecting them to water repellency treatment. The procedure for subjecting the regenerated fiber viscose rayon to water repellency treatment will be described with reference to FIG. In this figure, 18 is a known viscose rayon manufacturing apparatus,
19 is a dryer, 21 is a water repellent treatment tank containing a water repellent 20, 22 is a pair of squeezing rollers, 23 is a dryer, 24 is a curing device,
25 is a winding device. As the water repellent 20 described above,
For example, product names Asahi Guard AG-710 and AG-730
A 5 to 7% solution (all manufactured by Asahi Glass Co., Ltd.) is used.

In the apparatus constructed as described above, the viscose rayon 26 fed from the viscose rayon production apparatus 18 passes through the dryer 19 to be pre-dried at an appropriate temperature, and the water repellent treatment tank 20. It is submerged in the water repellent 21 inside. Then, the viscose rayon 26 is appropriately squeezed by a pair of squeezing rollers 22, dried by a dryer 23, and passed through a curing device 24, for example, at 150 ° C. for 3 minutes or 170 ° C. for 1 minute. After being cured, it is wound by the winding device 25. Incidentally, the viscose rayon 26 may be applied to the viscose rayon 26 by means such as showering or spraying, without being submerged in the water repellent agent 21.

The viscose rayon 26 thus water-repellent treated, unlike the water-repellent treated water, has a small decrease in strength when wet and has properties almost equivalent to those of the above-mentioned strong rayon. . The so-called water-repellent treated vegetation bags 1 and 2 are knitted using the water-repellent treated viscose rayon 26. The vegetation bags 1 and 2 are knitted using a corrosive material. Therefore, the vegetation bags 1 and 2 may be immersed in a water repellent agent, or may be subjected to water repellent treatment by means of showering or spraying the water repellent agent.

The following experiments were conducted to examine the degree of corrosion and tensile strength of the water-repellent vegetation bag. That is, two vegetation bags were knitted and woven with 2000 denier viscose rayon which was not treated for water repellency, and only one of the vegetation bags was treated for water repellency by the above-mentioned spray of Asahi Guard AG-710. When it was laid on the slope facing south and the degree of corrosion and the tensile strength after the laying were examined, the results shown in Table 1 were obtained.

[0031]

[Table 1]

As is clear from Table 1, the water-repellent vegetation bags 1 and 2 maintain the tensile strength of about 96% of the initial value even after half a year, and the degree of corrosion when reduced. (That is, the degree of decrease in tensile strength) was about 4%, and it was found that corrosion hardly progressed.

Although the corrosion slightly progressed with the passage of time, the tensile strength was 90% of the initial value even after one year.
The degree of corrosion is maintained (corrosion is about 10%), and the tensile strength decreases sharply after two years, but the degree of decrease in tensile strength is still about 40%, and there is still sufficient tensile strength. The vegetation bag 1, which has such characteristics
It is no exaggeration to say that 2 has a function equivalent to that of the strong rayon vegetation bags 1 and 2 described above, that is, the vegetation bags 1 and 2 made of a corrosive material treated to be water-repellent. However, it is easy to understand that the green protection on the slope is permanently maintained.

Although the above-mentioned water repellent treatment is intended for viscose rayon 26, various corrosive materials such as the above-mentioned microbial-degradable plastics and photodegradable plastics are also subject to the water-repellent treatment, and The vegetation bag 12 knitted with a corrosive material can be the target of the water repellent treatment.

When the water repellent treatment target is a chemical fiber other than a cellulosic type, for example, a 3 to 5% solution such as the above mentioned trade name Asahi Guard AG-710 or AG-730 is suitable. Depending on the object to be treated, other silicone-based, fluorine-based, wax-based water repellents and the like can also be suitably implemented.

As can be understood from the above description, the vegetation bags 1 and 2 made of a corrosive material are subjected to a water repellent treatment to maintain a desired strength within a predetermined period after being laid on the slope. While it is possible to gradually corrode after a lapse of time, it is also possible to use an adhesive for the water repellent treatment for imparting such characteristics. As an adhesive used for this treatment, for example, acrylic resin type trade name Polysol A-403-2 or AT
-130, other AP-6710 (both manufactured by Showa High Polymer Co., Ltd.), etc. can be selected, these are diluted 2 to 3 times, and the vegetation bag 1 woven and woven with the corrosive material itself or the corrosive material 1 , 2 or by dipping the diluted adhesive in the corrosive material itself or the vegetation bags 1, 2 woven with the corrosive material.

As mentioned above, the corrosion is due to the presence of bacteria and moisture, and by killing or keeping away the bacteria therein,
Corrosion can be delayed for a period of time. Therefore, the vegetation bag 1, which is woven or woven with corrosive material itself or corrosive material,
2, antifungal agents such as Benlate (made by DuPont), Topjin M (made by Nippon Tanka Co., Ltd.), and Xylamon EX (made by Takeda Pharmaceutical Co., Ltd.)
Vegetation bags 1, 2 coated with antibacterial agents, antiseptics, etc. or woven with corrosive material itself or corrosive material
May be dipped in these chemicals.

Further, in each of the above embodiments, a part or all of the front or back net-like body may be formed of the above-mentioned material, and the back and middle net-like bodies and the connecting threads may be made of a corrosive material, for example. It is also possible to employ flat yarns of leather, wool, cotton, hemp, pulp, polyolefin fibers, and so-called regenerated fibers (viscose rayon is particularly preferable).

[0039]

As described above, according to the present invention, since the front and back mesh bodies or the back and middle mesh bodies are connected by a plurality of connecting threads, the upper end opening is formed into a circular shape as in the conventional case. Since it opens in a uniform width without opening, it can be prevented from shifting even if soil is put into it, and it is possible to prevent bagging of soil with an excessive weight, easy to carry and other handling, and easy to construct. When the plant is filled with the vegetation material or the vegetation growth base material, the weight can be reduced to a predetermined value and the quality control can be easily performed.

Further, according to the present invention, strong rayon is selected as a constituent material of the vegetation bag, or a corrosive material is used as a constituent material of the vegetation bag and is subjected to an antiseptic treatment. A vegetation bag that maintains the desired strength inside and gradually corrodes after that period is obtained, and during the above period, the runoff of soil and vegetation base material in the sandbag is effective. Of the vegetation seeds, the growth and overgrowth of the vegetation seeds provide permanent protection of the greenery on the slopes. Since the rooting property is improved, it is possible to provide a vegetation bag made of an ideal material for protection on the slope.
