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. 6 (A) and (B), one of the above-mentioned slope greening methods is to stack two chemical nets, for example, 30 to 50 cm.
The net body main body 62 having the accommodating portion 61 is formed by forming the portions which are not woven about 5 cm or the portions which are not fused with each other at every interval, while the fertilizer and the soil improving agent are contained in the bag 63 made of the non-corrosive non-woven fabric. , A fertilizer base material 64, such as a water retention agent, which is directly or indirectly necessary for the growth of plants is formed to form a fertilizer base material bag 65, and the fertilizer base material bag 65 is accommodated in the accommodating portion 61 and reticulated. After stretching the body 66 on the slope 69 using the anchor 67, the peg 68, etc., the seed, the organic matter, the chemical fertilizer, the soil improving agent,
For example, a vegetation base material 70 in which a water retention agent or the like is formed into a gel is used as a reticulate body.
There is a method of spraying from above 66 with a spraying machine so as to have an appropriate thickness.

According to this construction method, the net-like body 66 prevents the vegetation base material 70 from extinguishing, and the seeds contained in the vegetation base material 70 germinate and grow in early stages. By appropriately supplying the fertilizer in 70 and the fertilizer base material 64 in the fertilizer base material bag 65, the plant can be surely grown on the slope 69 where the growth of the plant was difficult.

[Problems to be Solved by the Invention]

By the way, vegetation base material
70 tends to be sprayed thickly, for example, 3 to 5 cm, and in such a construction method, from the viewpoint of preventing runoff of the vegetation base material 70, the upper surface side of the net body 66 is the vegetation base material.
It is desirable that the net is located approximately in the middle of 70. However, in the conventional mesh body 66, the two nets are almost in close contact with each other except the accommodating portion 61 accommodating the fertilizer base bag 65. Since there is no thickness, it has a slope 69
As a result, the effect of preventing the vegetation base material 70 from running away due to rainfall or freezing is weak.

On the other hand, it is conceivable to reduce the mesh of the reticulated body 66, but by doing so, even if the vegetation base material 70 is sprayed from above the reticulated body 66 with a spraying machine, the vegetation base material 70 will have a reticulated mesh. However, there is a disadvantage that the spraying work is troublesome.

The present invention has been made with the above matters in mind, and an object thereof is to reliably prevent the vegetation base material that has been sprayed thickly against the slope from running away, and
It is to provide a reticulated body that can efficiently spray a vegetation base material.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, in the present invention, a net-like body formed by laterally forming a storage portion between both nets of a net-like body having a double paper structure formed by superposing a front net and a back net. In the above, the wefts of the both nets facing each other are bound every other row or every other row.

[Action]

In the net-like body having the above structure, when the fertilizer base material bag or the like is accommodated in the accommodating portion and is stretched on the slope, for example, the portions that are bound in every other row are joined together with the front net and the back net. Since it has a layered structure, the thickness of the portion other than the accommodating portion of the net-like body increases accordingly,
Since the vegetation base material is sprayed so as to be thick on the slope and the resistance of the mesh body to the vegetation base material is large, it is possible to reliably prevent the vegetation base material from running away. Further, since it is not necessary to make the mesh size of the mesh body smaller than necessary, and rather, the mesh size can be made larger than the conventional one, the vegetation base material can be sprayed efficiently.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

1 (A) to (C) show an example of a mesh N according to the present invention,
Reference numeral 1 denotes a net body having a double net structure, which includes a front net (upper net) 2 and a back net (lower net) 3, and
A plurality of accommodating portions 4 are formed between the nets 2 and 3 at appropriate intervals. And the meshes on both nets 2 and 3 are 1 inch (2.54
cm). In FIG. 1 (A), 5 is a reinforcing rope.

The structure of the mesh N and the manufacturing method thereof will be described in more detail with reference to FIGS. 2 and 3. In the front net 2, as shown in FIG. 2, the warp yarns 6 are, for example, polyethylene of 800 denier. It is formed by chain-knitting a monofilament 2 made of (PE) yarn,
The weft yarn 7 orthogonal to this is formed by knitting, for example, a 1500 denier PE yarn so as to proceed in a zigzag manner between two adjacent warp yarns 6. In the back net 3, as shown in FIG. 2, the warp 8 is formed by chain-knitting a monofilament made of, for example, PE yarn having a denier of 800, and the weft 9 orthogonal to the monofilament is, for example,
Monofilament 9A made of 1500 denier PE yarn and flat yarn made of, for example, 1000 denier polypropylene (PP) yarn (eg, width 2.5 mm, thickness 49 μ
m) 9B is formed by knitting between two adjacent warp threads 8 in a zigzag manner.

And these front net 2 and back net 3 are
As shown in FIG. 3, the warp yarns 6 and 8 are woven together to leave a portion which is not knitted at appropriate intervals and are formed into a net body 1 having a double net structure. (Measuring amount) is formed in the accommodating portion 4,
The warp yarns 6 and 8 facing each other of the nets 2 and 3 are stitched in every other row by a binding yarn 10 made of a monofilament made of, for example, 800 denier PE yarn. In this binding, for example, five stitches of the warp yarns 6 and 8 are bound by the binding yarn 10, and are inserted into any of the warp yarns 6 and 8 in the accommodating portion 4, and the binding portion is opened (see FIG. 1). (A), (B), (C)
reference). The weight of the reticulated body N configured in this way is 78.5 g / m ² excluding the reinforcing rope 5.

Referring again to FIG. 1 (A), 11 is a fertilizer base bag accommodated and held in the accommodating portion 4, which is made of a corrosion-resistant non-woven fabric.
A fertilizer base material 13 such as a fertilizer, a soil conditioner and a water retention agent, which is directly or indirectly necessary for plant growth, is housed in the inside 12.

When spraying the vegetation base material on the slope, first, as shown in FIGS. 1 (A) and 4, insert the fertilizer base material bag 11 into the accommodating portion 4 of the reticulated body N, and mount it. Anchor this
The back net 3 side is stretched by using 14 or pegs 15 so that the back net 3 side is close to the slope 16. In this case, as shown in FIG. 5, the portions 17 that are bound in every other row form a three-layer structure together with the front net 2 and the back net 3, so that the portion of the net N other than the accommodating portion 4 is only that much. The thickness increases.

In this way, after the three-layer structure net N is stretched on the slope 16,
For example, the seeds and the vegetation base material 18 in which the organic substance, the chemical fertilizer, the soil improving agent, the water retention agent, etc. are made into a gel form are sprayed from above the reticulated body N by a spraying machine so that the thickness is, for example, 1 to 5 cm. (See FIG. 5). In this case, even if the vegetation base material 18 is sprayed to the slope 16 so as to be thick, the front net 2 is positioned almost in the middle of the sprayed vegetation base material 18 as shown in FIG. Therefore, the resistance of the reticulate body N to the vegetation base material 18 increases, and
We can surely prevent the exodus of 18. Further, since the mesh N does not need to be made smaller than necessary and can be made larger than the conventional one, the vegetation base material 18 can be efficiently sprayed and the vegetation base material 18 can be used as a method. It can be brought into close contact with the surface 16.

The present invention is not limited to the above-described embodiment. For example, when the mesh body main body 1 has a relatively small mesh, the warp yarns 6 and 8 of the front net 2 and the back net 3 facing each other are provided.
May be bound every several rows (for example, 2 to 3 rows). The configurations of the both nets 2 and 3 can be set arbitrarily. For example, the both nets 2 and 3 may have the same configuration, and the flat yarn 9B is provided only on the front net 2 side to Only the monofilament 7 may be provided on the net 3 side. Furthermore, the meshes on both nets 2 and 3 do not necessarily have to be the same, and may be different from each other.

Further, the vegetation base material 18 is not limited to the gel-like material described above, and may be a dry one in which seeds are simply mixed with an organic substance, a chemical fertilizer, a soil conditioner, and a water retention agent without using water.

〔The invention's effect〕

Since the present invention is configured as described above, it is possible to reliably prevent the vegetation base material thickly sprayed on the slope from falling off due to rainfall or freezing. Since the mesh size does not have to be made smaller than necessary, the vegetation base material can be sprayed smoothly, the construction efficiency is improved, and the quality of slope greening can be improved.
