Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a vegetation base material holding net (hereinafter simply referred to as a net) used in, for example, a slope greening method.

[Conventional technology]

As shown in FIGS. 10 (A) and 10 (B), one of the above-mentioned slope greening methods is one in which two nets made of a chemical material are overlapped and, for example, a portion which is not woven about 5 cm at intervals of 30 to 50 cm or While forming a net-like main body 42 having a housing portion 41 by forming a portion that is not fused to each other, fertilizer, a soil improver, a water retention agent directly in the growth of plants such as a bag 43 made of a corrosion-resistant nonwoven fabric. Alternatively, a fertilizer base bag 45 is formed indirectly by containing the required fertilizer base material 44, and the net-like body 46 in which the fertilizer base material bag 45 is housed in the housing portion 41 is used as an anchor 47, a peg 48, or the like. After being stretched on the slope 49 using, seeds, organic matter, chemical fertilizer,
Soil conditioner, water retention agent, etc.
There is a method of spraying 50 onto the net-like body 46 by a spraying machine so as to have an appropriate thickness.

According to this method, the net-like body 46 prevents the vegetation base material 50 from running away, and the seeds contained in the vegetation base material 50 germinate and grow vegetatively at an early stage. By appropriately supplying the fertilizer in 50 and the fertilizer base material 44 in the fertilizer base material bag 45, the plant can be surely grown on the slope 49 where the growth of the plant was difficult.

[Problems to be Solved by the Invention]

By the way, the reticulate body 46 is conventionally formed by braiding a warp yarn a formed by chain-knitting a polyethylene yarn, for example, a weft yarn b made of polyethylene yarn with a width of 6.5 mm and a thickness of 16 μm and a thickness of 1000 denier. It is used.

However, the polyethylene yarn is soft, and therefore, when a flat yarn having the above-mentioned width is braided, it becomes crumpled and becomes substantially narrower. Moreover, the weft yarn b made of this flat yarn extends in the lateral direction of the slope 49. When provided alongside, since the weft b is soft, the effect of preventing the vegetation base material 50 from running away is weak due to too close contact with the slope 49.
Due to the weight of the sprayed vegetation base material 50, the weft b may be stretched out, and the vegetation base material 50 may not be completely prevented from running away.

On the other hand, it is conceivable to reduce the mesh size of the net-like body 46, but by doing so, even if the vegetation base material 50 is sprayed from above the net-like body 46 with a spraying machine, the vegetation base material 50 has a mesh-like shape. However, there is a disadvantage that the spraying work is troublesome.

By the way, the major purpose of applying the greening method to the slope is to restore the slope to the original mountain and it is also required to have an aesthetic appearance with flowers, but the slope is stable only with native plants such as wildflowers and trees or flowers. The vegetation base material that cannot be protected against
In addition to the native species plant or flower, an alien species plant such as grass is added to 50, and the vegetation base material 50 in which the native species plant or flower and the alien species plant are mixed is sprayed from above the reticulate body 46 by a spraying machine. Was doing.

However, the native species plants and flowers germinate and grow later than the exotic plants. It cannot be grown sufficiently because it is pressed by exotic plants, and only exotic plants become green. However,
Exotic plants grow fast but die out in a short period of time,
After all, it becomes a short-term greening, and there is a problem that the greenery on the slope cannot be maintained permanently.

The present invention has been made in view of the above matters, and an object of the present invention is to surely prevent runoff of a vegetation base material without reducing the mesh size, and further, to prevent alien species such as grass. It is an object of the present invention to provide a reticulate body that can surely germinate and grow native seed plants and flowers such as wildflowers and trees without being pressed by seed plants.

[Means for Solving the Problems]

In order to achieve the above object, the present inventor has reached the following means as a result of various studies.

That is, a housing portion is formed in the lateral direction between the both nets of a net body having a double structure formed by stacking a front net and a back net, each of which is composed of a chain-knitted warp yarn and a flat yarn weft yarn. In the first aspect of the present invention, there is provided a vegetation base material holding mesh body, wherein the flat yarn has a denier of 500 to 3000, a width of 2 to 5 mm, and a thickness of 30.
A polypropylene fertilizer base bag containing a fertilizer base material in the bag, and a vegetation bag containing vegetative seeds in the bag are used. In the invention of 2, the flat yarn has a denier of 1000 to 3000, a width of 2 to 5 mm, and a thickness of 30.
A polyethylene fertilizer base material containing a fertilizer base material in the bag and a vegetation bag containing vegetation seeds in the bag are housed in the housing part while using a polyethylene thread having a size of up to 200 μm.

[Action]

According to the first aspect of the present invention, the polypropylene yarn itself has a higher rigidity than the polyethylene yarn, and therefore the rigidity of the flat yarn as the weft yarn is sufficiently higher than that of the conventional one even if it has a small diameter.

Further, according to the second aspect of the invention, the flat yarn itself as the weft thread becomes thicker, so that the rigidity is increased.

Then, in any of these inventions, the rigidity of the weft is increased, whereby the runoff of the vegetation base material can be reliably prevented. Moreover, since the texture is the same as before, the vegetation base material can be sprayed as smoothly as before.

Further, in any of the above inventions,
For example, a fertilizer base material bag containing a fertilizer base material in a bag and a vegetation bag containing an alien seed plant seed as a vegetation seed are contained in the bag, while the local area is contained in the vegetation base material sprayed on the slope. If you put seeds of wild plants and trees and flowers that are seed plants and spray this vegetation base material against the slope, you can grow native seed plants and flowers with alien seed plants,
The greenery of the slope can be maintained permanently and at the same time the aesthetics can be improved.

〔Example〕

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 to 3 show a mesh body according to a first embodiment of the present invention. In these figures, N is a mesh body, and its main body 10 is composed of a front net 11 and a back net 12. The warp yarns 13 and 14 in both nets 11 and 12 are formed by chain-knitting polyethylene (PE) yarns, respectively.

More specifically, in the front net 11, one flat yarn (for example, a width of 2.5 mm and a thickness of 49 mm) made of, for example, 1000 denier polypropylene (PP) yarn is used.
.mu.m) 15 and one monofilament 16 made of, for example, 1500 denier PE yarn are braided with the warp 13 in a large number as wefts at appropriate intervals. And, as shown in FIG. 3 in particular, the flat yarn 15 is braided so as to proceed in a zigzag shape between two adjacent warp yarns 13. In the back net 12, a single monofilament 17 made of 1500 denier PE yarn is braided with the warp yarns 14 as weft yarns at appropriate intervals.

The front net 11 and the back net 12 are warp threads 13,
14 are woven together to leave a non-weaved portion at an appropriate interval to form a net body 10 having a double net structure, and the non-woven portion is formed in the accommodating portion 18.
The weight of the reticulated body 10 configured in this way is 77.6.
It is 4 g / m ² .

Further, in FIG. 1, 19 and 20 are the accommodating portions, respectively.
A fertilizer base bag and a vegetation bag that are housed and held in 18. The fertilizer base bag 19 is made of a corrosion-resistant and insoluble non-woven fabric having a thickness and air permeability that allows fertilizer nutrients to gradually exude due to rainfall and the like. It contains a fertilizer base material that is necessary for growth directly or indirectly. Also, the vegetation bag 20 is a germination of vegetation
In a bag made of a polymer film or starch film that does not hinder growth and dissolves with water, or water-soluble paper with a gauze (for example, Ponic (trade name): Ikeda Paper Industry Co., Ltd.), It contains grass seeds. Here, examples of grass seeds include green pinged red fescue, high-lined bend grass, red top, bermuda grass, and Kentucky blue grass, which may be appropriately selected and stored in a bag. At this time, a water retaining material and some fertilizer may be stored in the bag.

Thus, when spraying the vegetation base material on the slope, first, as shown in FIGS. 1 and 4, the fertilizer base material bag 19 and the vegetation bag 20 are inserted and mounted in the accommodating portion 18 of the mesh N. Then use the anchor 21 and pegs 22 to attach the back net 12
The vegetation bag 20 is stretched so that the side is close to the slope 23 and the vegetation bag 20 is located above the fertilizer base material bag 19.

Thus, in the reticulated body N having the above-mentioned configuration, the weft yarns P
Since one flat yarn 15 made of PP yarn and one monofilament 16 made of PE yarn having higher rigidity than the E yarn is used, the rigidity of the weft yarn is increased and therefore the slope 23
If it is stretched over, it will not stick too close to the slope 23.

In this way, from above the reticulated body N stretched on the slope 23,
The seeds, organic substances, chemical fertilizers, soil improvers, water retention agents, etc. are mixed and sprayed on, for example, a gel-like vegetation base material. The seeds used at this time are yellow daisies, French chrysanthemums, danishikigiku, saws. grass, Haetori pink, California poppy, Murasakihanana, Baby's Breath, cosmos, cockscomb, Kawaranadeshiko, flowers and seeds, such as Gaillardia pulchella, mugwort, Japanese pampas grass, Medohagi, seeds of wild plants such as Japanese knotweed or, pine, Alnus firma, weasel There are tree seeds such as Hagi, Yamahagi, and Komatsunagi, and these may be appropriately selected.

Then, the gel-like vegetation base material is sprayed from above the net-like body N by a spraying machine so as to have an appropriate thickness. In addition, in FIG. 4, 24 shows the sprayed vegetation base material.

Even if the vegetation base material 24 is sprayed in this manner, the weft yarns of the reticulate body N do not fully extend due to the weight of the vegetation base material 24, so that the vegetation base material 24 is almost completely prevented from running away. can do. Then, in this case, as shown in FIGS. 2 (A) and 2 (B), some of the flat yarns 15 having high rigidity stand up, so that the runoff of the vegetation base material 24 can be better prevented. . Also, monofilament 16
Since it also functions as a reinforcing material, the effect of preventing the vegetation base material 24 from running away is improved compared to the conventional net-like body of this type. Further, it is not necessary to make the mesh of the mesh body 10 smaller than necessary, but rather, it can be made larger than the conventional one, so that the vegetation substrate 24 can be efficiently sprayed and the vegetation substrate 24 is It can be closely attached to the slope 23.

Thus, on the slope 23, the grass in the vegetation bag 20 accommodated in the accommodating portion 18 of the net-like body N grows quickly and grows in a streak shape to protect the slope 23. Then, in other parts of the reticulate body N, wild grass, trees and flowers germinate from the sprayed vegetation base material 23, but since it is distant from the pasture grass, it can grow without being affected by the pressure, and the slope 23 The entire plant will be green.

5 (A), (B) and FIG. 6 show a mesh body 10 according to a second embodiment of the present invention. In this embodiment, as a monofilament provided on the front net 11 and the back net 12, respectively. , 16 ', 17' of 800 denier, which is slightly thinner than that of the first embodiment, is used.
Other configurations are unchanged. The weight of the mesh body 10 according to this example is 77.64 g / m ² .

7 (A), (B) and FIG. 8 show a mesh body 10 according to a third embodiment of the present invention, and in this embodiment, the structure of the mesh body 10 according to the second embodiment. Back to 12
As a weft yarn of, similar to the construction of the front net 11, one flat yarn (this flat yarn is the same as the flat yarn 15 of the front net 11) 25 made of 800 denier PP yarn is added to the front net 11. The back nets 12 are configured so that they have exactly the same form. The net body according to this embodiment
The weight of 10 is 68.61 g / m ² .

It goes without saying that the reticulated body main body 10 according to the second and third embodiments has the same or more effects as the reticulated body main body 10 according to the first embodiment.

Although not shown, in the net body 10 according to the third embodiment, the monofilaments 16 'and 17' may be removed from the configuration of the front net 11 and the back net 12.

Further, as the flat yarn 15 (or 25) in each of the above-mentioned embodiments, P of the above-mentioned denier number, width and thickness is used.
Not limited to P thread, 500-3000 denier,
A PP yarn having a width of 2 to 5 mm and a thickness of 30 to 200 μm can be appropriately selected and used.

In each of the above embodiments, the flat yarn 15 (or
25) is composed of PP yarns, the present invention is not limited to this, and instead of PP yarns, flat yarn 15
(Or 25) slightly thicker PE of 1000 to 3000 denier
You may comprise with a thread. For example, if you make a flat yarn 15 (or 25) with 1000 denier PE yarn,
The thickness should be 2.5 mm and the thickness should be 46 μm.

Thus, by using a thicker PE yarn than in the past, the rigidity of the weft yarn is increased, and when it is stretched on the slope, it does not adhere too much to the slope and the sprayed vegetation base material Because of the weight of the weft, the weft will not be stretched out, and the runoff of the vegetation base material can be almost completely prevented. Even when the flat yarn 15 (or 25) is made of PE yarn, it is possible to appropriately select and use one having a denier of 500 to 3000, a width of 2 to 5 mm, and a thickness of 30 to 200 μm.

Further, in the above-described embodiment, the constituent members of the vegetation base material 24, in which the seeds of an alien plant such as grass are stored in the vegetation bag 20 housed in the housing portion 18 of the reticulated body N and sprayed on the slope 23. As seeds of native species plants such as wildflowers and trees are used as the seeds, instead of this, the seeds of native species plants and flowers are stored in the vegetation bag 20 and the seeds of alien species are used as constituent members of the vegetation base material 24. You may make it use a seed.

Then, the vegetation base material 24 is not limited to the gel-like one, and may be a so-called dry type that does not use water in which the seed and the organic matter, the chemical fertilizer, the soil conditioner, and the water retention agent are simply sufficiently mixed. .

In the above-mentioned embodiment, the gel-like (or dry-type) vegetation base material 24 is sprayed from above the net-like body N laid on the slope 23, but the net-like body N according to the present invention is as follows. It can also be used for constructions other than the above method, for example, a construction method in which the vegetation base material 24 is not sprayed on the mesh N. This will be described with reference to FIG.

That is, FIG. 9 (A) shows one in which the mesh N is laid on the slope 23, and in this example, the fertilizer base bag 19 and the fertilizer base bag 19 are provided in every other accommodating portion 18A. A vegetation bag containing the seeds of annual flowers such as California poppy, purple hanahana, gypsophila, cosmos, citrus, and seeds of perennial flowers such as kawaranadeshiko, ginseng, sawtooth grass, french chrysanthemum, and danishiki chrysanthemum. 20
In addition to accommodating A and A, a vegetation bag 20B in which the seeds of grass such as Kentucky bluegrass, Bermudagrass, and Olympic tall festival are properly selected and accommodated is accommodated in the accommodating portion 18B between them.

In addition, in the same figure (B), the seeds of the annual flower plant 26
