DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope greening method using a vegetation net knitted with jute yarn.

[0002]

2. Description of the Related Art In the revegetation method of a slope, a vegetation net is laid on a slope to be constructed, and a plant seed, a fertilizer, a soil improvement material, a water retention material, etc., which are necessary for growing a plant, are placed on the net. A method of spraying a vegetation base material that is a mixture of materials with a spraying machine, or attaching a thin cotton that decomposes or dissolves early due to moisture and dissolves into the environment on the lower surface of the vegetation net, And a method of laying on a slope a material which is bonded with a foam adhesive or the like.

[0003] Knitting a vegetation net used in such a slope greening method with jute yarn is very preferable in the following points.

[0004] That is, the vegetation net plays a role of preventing the movement or loss of the vegetation base material and a role of protecting the slope and preventing erosion until the vegetation is greened and protected. If it remains on the slope forever like a synthetic resin net, it not only hinders the growth of vegetation, but is also undesirable in view of the landscape. In this regard, jute yarn is a natural fiber, and when exposed to moisture,
Eventually, it will melt into the environment due to corrosion and will not remain on the slope forever.

[0005] In addition, since the surface of the jute yarn is fluffy, the vegetation net knitted with the jute yarn narrows the fiber gap due to the fluff, so that the net (slope) of the ground (slope) is relatively small. The coverage is increased, and the protection of the slope and prevention of erosion can be performed efficiently.

[0006] Knitting a vegetation net with jute yarn has such advantages, but also has the following disadvantages because the surface of the jute yarn is fluffy.

That is, when knitting into a net, the fluff on the surface of the jute yarn adheres to a movable portion (particularly, a knitting portion) of a loom or a knitting machine, and it is difficult to stably manufacture the net. However, it was difficult to apply the jute yarn to the sulzer which had a fuzz. In addition, the fluff is scattered during the production of the net, deteriorating the working environment, and there is a problem in the health of workers.

[0008]

DISCLOSURE OF THE INVENTION In view of the above situation, the present invention, despite being a vegetation net knitted with jute yarn, has a vegetation net constructed on a slope or the like, and has a water content due to rainfall or the like. Until it touches, it suppresses the fuzz on the surface, enables stable production, prevents the work environment from deteriorating due to the scattering of fluff, and makes full use of the advantages of knitting the vegetation net with jute yarn. It is intended to be.

[0009]

The technical measures taken by the present invention to solve the above-mentioned problems are as follows. That is, in the slope revegetation method of the present invention , a vegetation thread knitted with jute yarn whose fuzz is prevented by a water-soluble glue.
By stretched the Tsu door to the slope, by the moisture of the rain, etc.
Dissolve the water-soluble glue to form a vegetation net.
Restores the fluff of the cotton thread to cover the vegetation net
It is characterized by raising the rate . In addition, you may use the vegetation net which used the jute thread which prevented fluffing by the water-soluble glue for both the warp and the weft,
A vegetation net using jute yarn whose fluff is prevented by a water-soluble glue may be used only for the warp or weft.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a slope greening method according to the present invention.
FIG. 2 is an explanatory diagram of a configuration of a vegetation net 1 used in the method, and FIG. 2 is an explanatory diagram of a production line of the vegetation net 1. The above-mentioned production line is composed of a jute yarn feeding device 3, a water-soluble glue coating device 4, and a net making machine 5 such as a sluser. In the above-mentioned production line, the jute yarn 2 of the present invention is not always supplied continuously to a net manufacturing machine such as a throughr.

As shown in FIG. 1 (C), the vegetation net 1 is knitted with jute yarns 2 which are prevented from fluffing by a water-soluble glue.

More specifically, as shown in FIG. 1A and an enlarged view in the right circle of FIG. 2, a jute yarn 2 having an innumerable fluff a on its surface is continuously or intermittently fed from a feeding device 3. In the water-soluble glue application device 4,
By applying and drying the water-soluble glue b, FIG.
As shown in FIG. 2B and an enlarged view in the left circle of FIG. 2, the jute yarn 2 in which the water-soluble glue b prevents fluffing is obtained.

Next, the jute yarn 2 is supplied to a net making machine 5 such as a sluser to manufacture the vegetation net 1 shown in FIG. 1 (C). At the time of this production,
Since the vegetation net 1 is knitted with the jute yarn 2 in which the fluff is prevented, the fluff a does not scatter around and deteriorate the working environment, and adheres to the movable part (particularly, the knitting part) of the net making machine 5. It does not hinder stable production.

The vegetation net 1 thus obtained
Since the water-soluble glue b is melted and loses the fuzz prevention function when it is exposed to water by rainfall or the like after construction on a slope or the like, it is knitted with a jute thread as shown in FIG. 1 (D). The original fluffy state of the vegetation net 1 is restored.

Therefore, in the vegetation net 1 used in the present invention,
Is a net for vegetation 1 until the coverage of the ground (slope) increases for the purpose of greening and greening and protection by vegetation are achieved.
This effectively protects the slope and prevents erosion.

Then, as time passes, corrosion progresses from the fine fluff a, and eventually, the entire body corrodes and melts into the environment.

The jute yarn 2 may be either a twisted yarn or a non-twisted yarn.
5th to 50th are used. In the illustrated example, the jute yarn 2 is used for each of the warp and the weft. However, the jute yarn 2 is used only in one of the warp and weft directions, and corrosive chemical fibers such as rayon or acetate and cotton are used in the other direction. Natural fibers, such as, for example, may be used. When the net making machine 5 is a weaving machine, it is desirable to set the crosswise direction (the number of wefts to be driven) to 2 to 15 yarns / inch and the vertical direction to about 1 to 20 cm.
In the case of a knitting machine, it is desirable that the mesh size be 0.5 to 10 cm in the horizontal direction and 0.5 to 10 cm in the vertical direction. Also,
At the stage of the jute yarn 2 or at the time when the vegetation net 1 is manufactured, it is also possible to perform an antibacterial treatment to extend the corrosion resistance period of the vegetation net 1.

[0018]

According to the slope greening method of the present invention, the water-soluble paste
For vegetation knitted with jute yarn to prevent fluffing
By stretching the net on the slope,
Dissolve the water-soluble glue to form the vegetation net.
To restore the fluff of the woolen thread,
The coverage is increased. In particular, vegetation nets
As the fuzz on the surface of the formed jute yarn is prevented,
When manufacturing a net, fluff does not adhere to a loom or a knitting machine, stable manufacturing is possible, and manufacturing with a throughr is also possible. In addition, since the scattering of fluff to the surroundings is prevented,
The working environment can be improved and the health of workers is not adversely affected. Nevertheless, since the fuzz is prevented by the water-soluble glue, if the vegetation net is applied to the slope or the like and then comes into contact with water due to rainfall, etc., the water-soluble glue dissolves and the function of suppressing the fluff is lost, The original fluffy state of the vegetation net knitted with the jute yarn is restored, and the advantage of knitting the vegetation net with the jute yarn as described at the beginning is fully utilized.
