Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vegetation mat used for greening roads, hillsides, riverbanks and riverbanks, for example.

[0002]

2. Description of the Related Art The above-mentioned vegetation mat for greening is obtained by bonding coarse fibers such as coconut fibers with an adhesive or the like.
It is known that a plant seed is supported on one surface of the bonded coarse fiber layer, and in a vegetation mat supporting the plant seed, the support surface of the plant seed is on the back side, and this is installed on a slope or the like, A vegetation mat that does not carry plant seeds is sown with plant seeds on a slope or the like, and then placed on a slope or the like to cover the seeds.

[0003] When the vegetation mat is installed in this way, it is difficult for the seeds to be washed away due to rainfall and the like, and the coarse fibers themselves and the air in the fiber layer maintain the heat retention, so that good germination of the seeds can be achieved. It is also very suitable in terms of vegetation because it can also prevent young shoots from strong sunlight.

[0004]

However, in the vegetation mat having the above structure, the coarse fibers are adhered and the fibers cannot move with each other. That is, the vegetation mat itself has many gaps between the fibers. However, since the fibers are fixed in shape by adhesion and the size of the gap is fixed, it is possible to prevent the sprouts of the seeds of the germinated plant seeds from becoming thick and to prevent the germ from elongating. In many cases, it was difficult to uniformly cover vegetation such as slopes.

The present invention has been made in view of the above circumstances, and has as its object to take a form of accumulation of a unique fiber to reduce the growth and growth of germs and the like. The point is to provide vegetation mats.

[0006]

The vegetation mat for revegetation according to the present invention, which has achieved the above object, spreads coarse fibers into a loose state having a substantially constant thickness, while at least one side of the coarse fibers is spread. With a coarse net
It is characterized in that both are sewn at coarse intervals with coarse stitches.

[0007] The vegetation mat having the above-mentioned structure is similar to the conventional one.
When installed so as to cover the plant seeds sown on a slope or the like, or as described in claim 2, when at least one of a fertilizer and a water retention material in addition to the plant seeds is supported on one surface of the layer of coarse fibers It is installed on a slope or the like with the supporting surface for plant seeds on the back side, and there is no difference from the conventional one in that it is suitable for vegetation such as prevention of plant seeds from flowing out due to rainfall or the like.

On the other hand, in the vegetation mat having the above-described structure, the coarse fibers are loosely accumulated so as to be movable with respect to each other without adhering the coarse fibers as in the related art. Germs of germinated plant seeds can easily expand and elongate the coarse fibers, and therefore, according to the vegetation mat according to the present invention, the coarse fibers do not inhibit the elongation of the young shoots Therefore, uniform growth of the vegetation such as the slope can be satisfactorily achieved by the growth of the seedlings.

Preferably, in terms of ecology, at least one of corrosive fibers such as wood wool and coconut fibers and linear or belt-shaped biodegradable plastic fibers is selected as coarse fibers. The sewing thread is selected from those made of corrosive fiber or biodegradable plastic fiber (claim 4).

[0010]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show a vegetation mat 1 for greening according to an embodiment of the present invention.

The vegetation mat 1 has a coarse net 3 spread loosely on a coarse net 2 with a substantially constant thickness, and another coarse net 3 is placed on the upper surface of the coarse fiber 3 layer. 4 and the coarse fibers 3 are sandwiched between two coarse nets 2 and 4 to form a sandwich.
4 is sewn with coarse seams a and coarse intervals L,
Further, on one surface of the coarse fiber layer, a vegetation material 5 obtained by adding a fertilizer and a water retention material to the plant seed b is supported by a water-soluble adhesive such as polyvinyl alcohol (PVA).

More specifically, wood such as wood wool (akamatsu) is coarsened as coarse fibers 3 to a thickness of 0.1 mm × 1.5 mm or a thickness of 0.3 mm × 2.5 mm. Used as packing, length is 30-45cm
It is specified in. ) And coarse net 2,
4, so that the wood wool 3 can be prevented from falling off,
Select the one with a 3 to 10 cm mesh size,
Is spread on the coarse net 2 so as to have a thickness of about 1 m ² so as to have a substantially constant thickness, and the coarse net 4 is superimposed on the layer of the wood wool 3 to make the pitch P of the seam a 3 to 15 cm. And at an interval L of 5 to 20 cm,
3, 4 are sewn.

The coarse nets 2 and 4 and the sewing thread 6 for sewing the wood wool 3 on the nets 2 and 4 are made of corrosive fiber or biodegradable so as to be suitable in terms of ecology. It is made of conductive plastic fiber.

The coarse fiber 3 is selected from corrosive fiber wool which is easily available and inexpensive and is ecologically suitable. Instead, corrosive fiber such as coconut fiber and the like are used. Even if a linear or band-shaped biodegradable plastic fiber is selected, it is suitable from an ecological point of view, and a plurality of these fibers may be appropriately selected and mixed for use.

Further, instead of sewing the three members 2, 3, and 4 only in one direction, they may be sewn vertically and horizontally as shown in FIG. 3, and the pitch P of the seam a at this time may be used. It is optional whether this is the same as the above-mentioned interval L or 3-15 cm in accordance with the seam a of the vegetation mat 1 shown in FIG.

As shown in FIG. 4, the vegetation mat 1 having the above structure is placed on, for example, a slope N with the supporting surface of the vegetation material 5 including the plant seed b on the back side, and the germination / growth of the plant seed b is performed. After waiting, the slope N is greened. The coarse fibers 3 provided on the vegetation mat 1 are loosely accumulated so that they can move with each other, and easily grow with the elongation of the germ of the plant seed b. , The germ is not hindered by the growth of the coarse fibers 3, but expands and easily expands the coarse fibers 3, so that the slope N depends on the growth of the plant seeds b. Vegetation coverage will be uniform.

In particular, when the vegetation mat 1 is sewn with the sewing thread 6 made of corrosive fiber or biodegradable plastic fiber as described above, when the vegetation mat 1 is constructed on the The sewing thread 6 is corroded and decomposed or decomposed,
The coarse fibers 3 become more loose and germinate on the slope N
This is preferable because the inhibition of the elongation of the germ of the growing plant is further reduced.

Although the vegetation mat 1 having the above-described structure supports the vegetation material 5 containing the plant seed b on one surface thereof, it is not always necessary to support the vegetation material 5; Even if the vegetation material 5 is not carried on the mat 1, if the vegetation mat 1 is placed so as to cover the plant seed after sowing the plant seed on the slope N or the like, as described above, the larvae are coarse. Since the fibers 3 are pushed and spread to easily ascend and extend, the slope N is uniformly covered with vegetation by the growth of the plant seeds b.

As the vegetation mat 1, the coarse fibers 3 are sandwiched between two coarse nets 2 and 4 in a sandwich shape, and the three members 2, 3 and 4 are sewn. It may be arranged only on one side, and both may be sewn. At this time, the vegetation material to be carried as necessary is a surface portion of the coarse fiber layer on the net side or a surface portion on the side where the net does not exist. May be carried on any of them.

[0020]

As described above, the present invention is characterized in that, in a vegetation mat for greening, the coarse fibers are loosely accumulated so that the coarse fibers move relative to each other as the young shoots grow. Therefore, according to the vegetation mat having such a configuration, since the upgrowth of the germ is not inhibited by the coarse fibers, uniform vegetation coverage such as a slope is favorably achieved.
