Tree planting using vegetation nets is being carried out. In this construction method, for example, a net that is knitted and woven with an appropriate texture is formed with a portion capable of accommodating a vegetation bag containing a vegetation base material including seeds, fertilizer, and water retention material, and laid on a slope. The fixing is performed using an anchor or a peg.

[0003] In such a construction method using a vegetation net, the runoff of the vegetation base material is prevented by the net, and the slope is greened by appropriately supplying fertilizer to the germinated and grown plants. The net can effectively prevent slope collapse and frost heave.

[0004]

However, in a snow-covered area, a normal vegetation net may be cut off by the weight of snow or a collapse (avalanche), and it is difficult to sufficiently protect the slope. In some cases, it was not possible. Further, when a net is formed of a synthetic fiber material, it does not corrode and remains behind, which causes a pollution problem.

The present invention has been made in view of such circumstances,
An object of the present invention is to provide a vegetation net that can withstand the weight of snow in a snowy area and does not cause a pollution problem.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a vegetation net with a wire net (hereinafter referred to as a net) according to the present invention will be described in detail below.
FIG. 1 is a schematic cross-sectional view of a net N, FIG. 2 is an exploded perspective view, and in these figures, reference numeral 1 denotes a wire net, 2 denotes a coarse palm net knitted with coconut fibers, and 3 and 4 denote water-soluble or hydrolyzed. 6 is a vegetation base material such as seeds, fertilizer, and soil improving material sandwiched between the two paper cloth pieces 3 and 4, 7 is a mesh or cloth piece, 8 is a suture thread, Palm net 2, vegetation base material 6
The vegetation sheet 5 and the net-like body 7 made of the paper cloth pieces 3 and 4 sandwiching the above are stacked in this order and integrated by sewing.

The wire mesh 1 has a mesh size of 10 to 70 m.
m, for example, 40 mm, a wire diameter of 0.5 to 3 mm, for example, 1 mm), and a net having a net width of 105 cm can be used. In addition, a rhombus wire mesh, a plain weave wire mesh, a crimp wire mesh, or the like can be used, and the wire can be a vinyl coating, particularly a biodegradable resin coating.

The palm mat 2 has a configuration in which the material (string) has a thickness of 1 to 10 mm, for example, 5 mm, and 5 to 15 lines, for example, 7 lines per 10 × 10 cm. Such a coconut net 2 has an excellent heat retention property and a high function of suppressing evaporation, and has a high function of preventing movement and runoff of the surface soil on the slope when it is attached to the slope. In general,
Corrosion occurs two to five years after construction, leaving no residue, so it does not cause pollution problems.

When the thickness of the coconut net material is 1 mm or less, the strength is reduced, and there is a possibility that the coconut net material is broken by running water. In addition, the closing property of the net is reduced, and the net covering effect is reduced. When the thickness is 10 mm or more, the obstructiveness is too large, which hinders the emergence from the plant net, and the knitting property is deteriorated. 5 to 1 per 10 × 10 cm
The use of five is also intended to keep the obstruction of the net at an appropriate level and to take into account the covering effect and the emergence of the plant.

The vegetation sheet 5 is formed by sandwiching a vegetation base material 6 such as a seed, a fertilizer, a soil improvement material, etc. between two water-decomposable or water-soluble paper cloth pieces 3 and 4, and a reinforcing kayak is provided on one side. It is preferable to use the ground. By setting the kaya ground on the lower side, the holding ability of the sandwiched large-grain fertilizer is improved. For the Kaya ground, use a corrosive net such as soup. Further, a thin cotton bonded to one side of a corrosive net, to which seeds, fertilizers and the like are bonded, can also be used.

As the suture 8, a biodegradable resin fiber thread, hemp thread, cotton thread, or the like can be used as a component of a corrosive product, and it is not always necessary to corrode (a part of the constituent material is used). If corrosion protection is required and the slope protection needs to be sustained), use corrosion-resistant polyester,
A yarn such as vinylon can be used. These yarns are mainly twisted yarns, and have a thickness of 0.5 to 3 mm. In the case of a plastic yarn such as polyester, a monofilament yarn can be used. In this case, approximately 0.3 mm is used. It is possible to use a high-strength plastic thread even if the thread has the same thickness. The stitching may be performed in the longitudinal direction at intervals of 3 to 50 cm (see FIG. 3A).

As another suturing method (FIG. 3)
(See (B)), it is also possible to use a stapler to integrate the respective materials at the above-mentioned intervals. In this case, the sewing can be performed with relatively simple equipment and the cost can be reduced. still,
In FIG. 3B, reference numeral 9 denotes a stapler needle.

As the material of the lowermost net-like body 7 in contact with the slope, a corrosive material is used, for example, hessian cloth (coarse hemp cloth), rayon nonwoven fabric, biodegradable resin net, Kaya ground, cotton cloth and the like can be used. It should be noted that a cloth material (not shown) may be used instead of the net-like body 7.

When the net N constructed as described above is mainly laid on the slope of a river, for example, on a low water floor 11 (see FIGS. 4 and 5), the coconut net 2 itself has a moderate durability. However, since the wire mesh 1 is stretched thereon, it has sufficient strength and is not cut by running water. In addition, the coconut net 2 has an excellent heat retaining effect, can prevent frost heave, and has a high germination / growth promotion effect, so that the seeds of native species carried by running water are established and early stable greening is achieved. Can be encouraged. If necessary, a peg or an anchor 10 may be cast and fixed on the slope (see FIG. 6).

The slope to which the net N is to be constructed is not limited to the river hydrophilic area, and is particularly suitable for snowy areas. The net N is prevented from being cut even by an avalanche at the time of melting snow, has an excellent heat retaining effect, and has a frost heave. It can prevent germination and enhance the germination / growth promoting effect. In addition, it can be applied to steep slopes because the effect of preventing the surface soil from collapsing is high. Since the palm net 2 has a high evaporation preventing effect, it is possible to sufficiently secure moisture for germination and growth of the plant even in a dry zone or a season with little rainfall.

On the other hand, the wire net 1 stretched on the surface of the net N, once bent, retains its shape, has good shape retention, and can easily adhere the net to a sloped surface having irregularities. Good workability. Further, the main members constituting the net N, the coconut net 2, the paper cloth pieces 3 and 4, the net-like body 7 and the like are corrosive and do not leave any residue on the slope,
There is no pollution problem. Further, the wire net 7 exhibits a slope protection effect for a considerable period of time, but eventually disappears.

Such a net N may be provided with a separately prepared fertilizer bag. In this case, for example, as shown in FIG. 7, the fertilizer bag 21 may be inserted into the bag-like portion 71 formed in the lowermost net-like body 7, and long-term stable replenishment of fertilizer nutrients and water retention to the established plants. The effect is exhibited and greening can be promoted more stably.

The vegetation sheet 5 includes a piece of paper cloth 3,
2. Instead of sandwiching the vegetation base material 6 between the four, a piece of paper cloth 3. It may be a turf body or the like in which the vegetation base material 6 is adhered to the surface with a water-soluble adhesive (see FIG. 8). Alternatively, the vegetation base material 6 may be directly bonded to the mesh body 7 with a water-soluble adhesive.

[0024]

As described above, according to the vegetation net with wire mesh of the present invention, a wire mesh is attached to one side of the coarse coconut net, and a vegetation sheet is attached to the other side, and these are integrally formed as appropriate. Because it was sewn to match, when applied to the slopes of rivers and snowy areas, the net is not cut even by running water or avalanches during snow melting, and the palm net has an excellent heat retaining effect, prevents frost heave, germination and growth It has a high accelerating effect and a high effect of preventing the surface soil from collapsing. In addition, the palm net has a high evaporation preventing effect, and secures moisture for germination and growth of plants.

Since a wire mesh is stretched on the surface,
Good shape retention, good workability on site, and good adhesion to the slope. In addition, since the main components are corrosive, no residue remains on the slope and no pollution problem occurs.
