Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art As the above-mentioned sandbag greening vegetation bag, there is one formed by sewing a net-like main body having a mesh capable of germination and growth of vegetation into a bag shape.
Vegetation materials are prepared by appropriately mixing vegetation seeds, fertilizers, soil conditioners, and organic matter such as bark and peat moss into the soil.

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

[0004]

The net-like main body constituting the above-mentioned vegetation bag is generally woven and woven with fibers made of synthetic resin, but these are different from plant-based or animal-based materials, and they are weather-rained over many years. There was a problem that it would not weather and corrode upon exposure to the soil and would not become homogenous with the vegetation base material and soil, and would worsen the growth and rooting properties of the 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 use a corrosive biodegradable plastic as a material for weaving a mesh body or bag, but these materials will not corrode after about two months have passed since they were laid on the slope. The period of two months is too short for seeds held in the sandbags to germinate, grow well and flourish, and the loss of tensile strength during this period means that the sandbags inside the sandbags are affected by rainfall and freezing. Since it is fatal in terms of preventing soil runoff, it has not been implemented yet.

From the above, as a material constituting the reticulated main body of the vegetation bag for greening, the tensile strength of the vegetation bag installed on the slope is as short as half a year, from the viewpoint of protection of the slope and growth of vegetation. Ideally, it should be maintained for about two years in anticipation of the situation, and should be equipped with the condition that it will eventually corrode and homogenize in the soil after the plant life has grown to some extent and grown. It is an object of the present invention to provide a vegetation bag for greening, which is made of a material having the above ideal conditions.

[0007]

In order to achieve the above object, in the first to third inventions, the net-like main body constituting the vegetation bag is knitted with strong rayon. Further, in the fourth to sixth inventions, the net-like main body constituting the vegetation bag is knitted and woven with a corrosive material that has been subjected to antiseptic treatment. Further, in the seventh to ninth inventions, the net-like main body constituting the vegetation bag is knitted and woven with a corrosive material, and the net-like main body is subjected to antiseptic treatment.

[0008]

In other words, the strong rayon (polynosic rayon or viscose rayon for tire cord) selected in the first to third inventions has higher tensile strength than materials such as general viscose rayon and biodegradable plastics. The strength reduction when wet is small, and the initial tensile strength of about 90% is maintained even after the half year of laying, and then the strength decreases with the passage of time, eventually corroding and becoming the same quality as soil. Shows the characteristics to be converted. A material that exhibits this property correctly fulfills the above ideal conditions, because the tensile strength of polynosic rayon is 3.4 g / D or more, and the tensile strength of viscose rayon for tire cord is 3.0 g / D. There are more.

In the fourth to ninth inventions, the constituent material of the vegetation bag is made a corrosive material, and then the vegetation bag is subjected to antiseptic treatment.
Therefore, even if it is a corrosive material,
By applying antiseptic treatment such as insect repellent (antifungal, antibacterial, etc.), the material strength of the vegetation bag can be maintained adequately for the second half to two years after laying, and eventually the antiseptic effect weakens or disappears. Corrosion begins with this, and it also becomes homogenous with the soil, and it is possible to obtain a vegetation bag with ideal conditions for slope protection equivalent to the above-mentioned strong rayon.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an example of a vegetation bag 1 for greening configured as a sandbag, and FIG. 2 shows a net-like main body 2 having a mesh for allowing germination and growth of vegetation which constitutes the vegetation bag 1. The upper end 2a of the net-like body 2 is folded back to tie the cord 7
The insertion portion 8 is formed, and the net-shaped main body 2 is folded in the left-right direction so that the left and right edges 2b and 2c and the lower end edge both sides are formed.
By sewing 2d and 2e together, the sandbag main body 9 shown in FIG. 3 is formed.

In the present invention, the net-like main body 2 constituting the above-mentioned greening vegetation bag 1 is made of polynosic rayon (a kind of strong rayon, and viscose rayon can also be suitably used). The yarn for knitting and weaving the mesh body 2 into a bag and the binding string 7 for binding the mouth portion are also made of strong rayon.

When greening the slope, a vegetation material obtained by appropriately mixing soil with vegetation seeds, fertilizer, water retaining material, soil improving material, etc. is put into the bag main body 9 and the mouth is tightly bound to the sandbag shown in FIG. Make up, bring this sandbag to a predetermined place on the slope,
The sandbags are attached or stacked in a lattice frame on the slope.

In the above-mentioned construction method, the strength of the net body 2, the sewing thread and the cord 7 is maintained for a period of about half a year to two years, and then the strength is reduced, and then the strength decreases with the passage of time. Since polynosic rayon, which has the property of corroding and homogenizing with the soil in time, is selected, runoff of the soil and vegetation material in the bag body 9 is effectively prevented at least during the above period.

During this period, the vegetation seeds in the bag body 9 germinate and grow, and the greening protection on the slope is achieved. The growth and rooting properties of
Even if the vegetation bag 1 is corroded, the greening protection on the slope is permanently maintained because the plants have been grown by then.

[0015] To the above vegetation material, for example, PM C-Zai (registered trademark of Jomo Ryokusan Kogyo Co., Ltd.), which is obtained by treating sewage sludge or the like into powder and granules, is added as an extender, or Since PMC-Zai has fertility and water-retaining property, it is possible to make only sandbags containing vegetative seeds into the bag main body 6 to form a sandbag.

[0016] Further, in the above-mentioned slope greening, a means of bringing sandbags into which the soil and vegetation materials have been put into the vegetation bag 1 for greening is taken to the slope.
A water-retaining material, soil conditioner, PM C-Zai, and other dry organic vegetation materials that have been appropriately mixed and mixed with organic substances such as bark and peat moss are pumped up to a predetermined point on the slope, and greening vegetation is applied to that point. It is also possible to take a bag 1 and put the above-mentioned vegetation material in the vegetation bag 1 for greening to form a sandbag, and to attach the sandbag to the sloped lattice frame or stack it. , Compared with the method of bringing sandbags to the slope, safe and efficient protection of slope slopes can be achieved.

FIGS. 4 to 6 show an example of a vegetation bag 1 for greening which constitutes a sandbag of another embodiment. In this embodiment, one half surface 2A of one side of a net-like main body 2 woven or woven from polynosic rayon is used. As shown in FIG. 4, vegetative seeds 3 such as grass and wild grass, a fertilizer 4 and a water retention agent 5 are added to the whole area of the water-soluble foaming adhesive 6 such as polyvinyl alcohol.
It is attached by.

The upper edge 2a of the mesh body 2 is folded back to form the insertion portion 8 of the string 7, and the half surface 2A on which the vegetation seeds 3 and the like are attached is folded in two so as to face the outer surface, and left and right thereof. Edge portions 2b, 2c and both lower end edge sides 2d, 2e are sewn together to form a sandbag bag body 9 shown in FIG.

The vegetative seed 3, the fertilizer 4 and the water retention agent 5 are directly adhered to the reticulated body 2, but in addition, a so-called turf grass in which the vegetative seed is sandwiched between two water-soluble papers. It is possible to employ means such as sticking the to the mesh body 2. Also,
The vegetation seeds 3 and the like are adhered to the entire half surface 2A of one side of the bag body 9 to form the bag body 9 with the vegetation seeds 3 and the like facing the outer surface, but the vegetation seeds 3 and the like are used on the inner surface. Alternatively, the vegetation seeds 3 or the like may be attached to a part of the half surface 2A, the entire area of one surface or a part thereof, and further, the entire area of both surfaces of the reticulated body 2. Alternatively, it can be carried out by attaching it to a part thereof.

For the greening of the slope, only the soil is put into the bag body 9 or a vegetation material obtained by appropriately mixing the soil with vegetation seeds, fertilizers, water retaining materials, soil improving materials, PM C-Zai, etc. 6 and with the mouth tightly bound Figure 6
Make up the sandbag shown in. The sandbags are brought to a predetermined place on the slope, and the vegetation seeds 3 and the like are directed outward, so that the sandbags are stuck or stacked in the lattice frame of the slope. In addition to the vegetation seeds in the bag body 9, the vegetation seeds 3 attached to the vegetation bag 1 germinate, grow, and flourish, and thus the greening protection on the slope is more favorably achieved. It

FIG. 7 shows an example of a vegetation bag 1 for greening which constitutes a sandbag of another embodiment. In this embodiment, when knitting or weaving the reticulated body 2 using polynosic rayon as a material, as shown in FIG.
The warp yarns 11 placed every other one in a range corresponding to the six weft yarns 10 are doubled on the front and back sides, and the weft yarns 10 are respectively applied to the front and back warp yarns 11.
The front and back sides are alternately entwined, and the bag accommodating portion 12 is attached to a part of the mesh body 2.
Is formed.

Then, on the entire half surface 2B of the net-like main body 2 on the side opposite to the bag accommodating portion 12, appropriate vegetative seeds 3 such as grass and wild grass are formed.
And a fertilizer 4 and a water retention agent 5 are pasted together with a water-soluble foaming adhesive 6 such as poly (vinyl alcohol), or so-called tension grass in which vegetative seeds are sandwiched between two sheets of water-soluble paper is a net body. 2 and the net body 2 is folded in two with the half surface 2B having the vegetation seeds 3 and the like facing outward, and the two sides are sewn together to form the bag body 9. ing.

As shown in FIG. 9, the bag accommodating portion 12 has a bag body 13 filled with one or more vegetation base materials 14 such as slow-acting or ultra-slow-acting fertilizer, water retaining material, and soil improving material. And a vegetative seed, a fertilizer, a water retaining material, a soil improving material, PMC Cai, and other organic substances such as bark and peat moss, soil, etc. are appropriately placed in the bag body 9 to form a sandbag.

It should be noted that a bag body 13 for filling the above-mentioned vegetation base material 14
In the case where the vegetation base material 14 contains vegetation seeds, it is preferable from the viewpoint of germination of vegetation seeds to select pulp, suf, or a relatively thin non-woven fabric obtained by blending them. When the vegetation base material 14 to be filled in the bag body 13 does not contain vegetation seeds, if pulp or rayon or a relatively thick non-woven fabric made by mixing these is selected, the fertilizer will slowly exude and the fertilizing effect will be long. It is preferable because it can be maintained over a period of time, or the runoff of soil improving materials, water retention materials, etc. can be effectively prevented, but it is not necessarily limited to these.

By the way, the vegetation bag 1 according to each of the above embodiments
Although strong rayon such as polynosic rayon and viscose rayon is selected as the constituent material of the reticulated body 2, the corrosive material is selected as the constituent material, and the corrosive material itself or the corrosive material is used. It is possible to apply water-repellent antiseptic treatment to the vegetation bag thus prepared and use it as a sandbag for protecting the greening of slopes.

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 bag 1, the progress of the corrosion can be delayed for a considerable period of time. 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. Natural fibers such as hemp and pulp are typical. 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 biodegradable plastics include trade name Tone (manufactured by AMKO, USA), trade name Pullulan (manufactured by Hayashibara Co., Ltd.), trade name Thor Fill (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 bag 1 is obtained by subjecting these to water repellent treatment. The procedure for subjecting the viscose rayon, which is a recycled fiber, to water repellent treatment will be described with reference to FIG. In this figure, 15 is a known viscose rayon manufacturing apparatus, 16
Is a dryer, 17 is a water repellent treatment tank containing a water repellent 18, 19 is a pair of squeezing rollers, 20 is a dryer, 21 is a curing device, 22
Is a winding device. The water repellent 18 may be, for example, a trade name of Asahi Guard AG-310 or AG-433.
A 5 to 7% solution (all manufactured by Asahi Glass Co., Ltd.) is used.

In the thus constructed apparatus, the viscose rayon 23 fed from the viscose rayon manufacturing apparatus 15 passes through the dryer 16 to be pre-dried at an appropriate temperature and the water repellent treatment tank 17 It is submerged in the water repellent 18 inside. Then, the viscose rayon 23 is appropriately squeezed by a pair of squeezing rollers 19, dried through a dryer 20, and passed through a curing device 21 at, for example, 150 ° C. for 3 minutes or 170 ° C. for 1 minute. After being cured, it is wound by the winding device 22. Incidentally, the viscose rayon 23 may be applied to the viscose rayon 23 by means such as showering or spraying, without being immersed in the water repellent agent 18.

The viscose rayon 23 thus water-repellent treated, unlike that before water-repellent treatment, 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 bag 1 is knitted using the water-repellent treated viscose rayon 23. The vegetation bag 1 is knitted using a corrosive material, and then the vegetation bag 1 is woven. The bag 1 may be dipped 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-310. To 1
When laid on a south-facing slope with a half-division slope and examined the degree of corrosion and the tensile strength after laying, the results shown in Table 1 were obtained.

[0032]

[Table 1]

As is clear from Table 1, the water-repellent vegetation bag 1 had an initial tensile strength of 96 after half a year.
%, The degree of corrosion when reduced (that is, the degree of decrease in tensile strength) was about 4%, and it was found that the corrosion hardly progressed. Although the corrosion progresses a little with the passage of time, the tensile strength maintains about 90% of the initial value even after one year (the degree of corrosion is 10%).
%, And the tensile strength sharply decreases after two years, but the degree of decrease in tensile strength is still about 40%, and the tensile strength is still sufficient. It is no exaggeration to say that the vegetation bag 1 that it has has the same function as the vegetation bag 1 made of strong rayon described above, that is, even if it is the vegetation bag 1 in which the viscose rayon 23 is treated to be water repellent. It is easy to see that the green protection on the slope is permanently maintained.

The above-mentioned water repellent treatment is intended for viscose rayon 23. However, 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 1 woven and woven with a corrosive material can be the target of water repellent treatment.

When the water repellent treatment target is a chemical fiber other than the cellulose 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 be preferably used.

As can be understood from the above description, by applying water repellent treatment to the vegetation bag 1 made of a corrosive material, it is possible to maintain a desired strength within a predetermined period after laying 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. Examples of the adhesive used for this treatment include acrylic resin-based products such as Polysol A-403-2 and AT-
130, other AP-6710 (both manufactured by Showa High Polymer Co., Ltd.), etc. can be selected, and these are diluted 2 to 3 times to form a vegetation bag 1 woven with a corrosive material itself or a corrosive material. It may be applied, or the diluted adhesive may be dipped in the corrosive material itself or the vegetation bag 1 woven with the corrosive material.

As mentioned above, the corrosion is due to the presence of bacteria and water, and by killing or keeping away the bacteria,
Corrosion can be delayed for a period of time. Therefore, the vegetation bag 1 woven or woven with corrosive material itself or corrosive material
In addition, the product name Benlate (made by DuPont), the product name Topzin M (made by Nippon Tank Co., Ltd.), and other product names Xylamon EX (made by Takeda Pharmaceutical Co., Ltd.), etc. Alternatively, the corrosive material itself or the vegetation bag 1 woven with the corrosive material may be dipped in these chemicals.

[0038]

As described in detail above, according to the present invention, strong rayon is selected as a constituent material of the vegetation bag for greening, or a corrosive material is used as a constituent material of the vegetation bag, and preservative-treated. By doing so, it becomes possible to obtain a vegetation bag that maintains a desired strength within a predetermined period and is gradually corroded after the period elapses, and thus the soil in the sandbag during the above period is obtained. Along with the effective prevention of runoff of vegetation and vegetation base material, vegetation seeds grow and grow during this period to achieve permanent protection of the greening of slopes, and
Since the vegetation bag is homogenized with the soil due to the subsequent corrosion, the growth and rooting properties of the vegetation are improved, and it is possible to provide a vegetation bag made of an ideal material for protection of slopes.
