Description

[Detailed description of the invention] This invention relates to a net-like body for vegetation.

Currently, one known method for protecting slopes is to cover them with nets to prevent falling rocks. Additionally, in this construction method, fertilizer bags are placed on the net in advance to green the slope at the same time. However, it is difficult to produce a net equipped with this fertilizer bag. This is because this kind of net is usually a double net, and when stacking these, it is necessary to prepare a pocket part in advance to accommodate the fertilizer bag. In addition to this drawback, the position where the fertilizer bag is stored is fixed depending on the position of the pocket.
The problem is that the mounting position cannot be adjusted. This is also inconvenient when a large amount of fertilizer is required to be applied to the soil on the slope.

The purpose of the present invention is to eliminate the above-mentioned drawbacks, and to provide a net-like body for vegetation that is easy to manufacture and allows for arbitrary adjustment of the attachment position of a bag containing materials necessary for vegetation. That's true.

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

In the drawings, reference numeral 1 denotes the entire net-like body, which is a double net consisting of an inner net 2 on the side in contact with the slope surface, and an outer net 3 superimposed on this and to which a fertilizer bag 4 is moored.

In this example, the inner net 2 is made of polyethylene fibers knitted by lattice knitting,
Frame cords 5 for tying the outer net 3 are woven into its peripheral and central portions. Further, the size of the mesh of the inner net 2 is approximately 1 cm in this example.

In this example, the outernet 3 is made of fibers such as polyethylene or polypropylene knitted by knotless knitting, and a border 6 is formed around the periphery by bundling together a plurality of net fibers.
The size of the mesh of the outer net 3 is larger than that of the inner net 2, and is approximately 4 cm in this example. Furthermore, the mesh fibers of the outer net 3 are made thicker than those of the inner net 2, and are made tougher to prevent relatively large diameter pebbles from falling.

Both the inner and outer nets 2 and 3 are tied together by partially tying the frame cord 5 and the edging 6 together with a tie cord 7 under the mutually overlapping position.

The fertilizer bag 4 is formed into a long cylindrical bag shape from non-woven fabric and encloses fertilizer therein. In this example, slow-release chemical fertilizers, soil conditioners, and the like are selected and used as the fertilizer depending on conditions such as the soil quality of the slope. Then, the fertilizer bags 4 are passed through the mesh of the outernet 3 every other bag as shown in FIG. It is moored by binding it. In the net-like body 1 shown in the figure, four fertilizer bags 4 moored as described above are arranged in parallel at approximately equal intervals.

Next, an example of constructing a slope using the mesh body 1 having the above structure will be described.

First, a plurality of net-like bodies 1 are combined so as to cover the entire surface of the slope to be constructed, and these are successively connected using connecting fittings. Then, after fixing this by driving an anchor into the upper part of the slope,
Expand it while hanging downward along the slope. After this, the earth retaining work and vegetation work are completed by spraying seeds onto the slope.

The various fertilizer components in the fertilizer bag 4 are gradually leached out by subsequent rainwater, etc., and are applied to the slope soil.

Next, the effects of the net-like body 1 of this example will be explained.

(i) It is easy to produce.

That is, unlike the prior art, there is no need to provide a special pocket for attaching the fertilizer bag 4. In other words, the reticular body of this example has inner meshes with different meshes.
This is because it is sufficient to simply overlap both the outer nets 2 and 3 and to anchor the fertilizer bag 4 to the mesh of the outer net 3.

(ii) The attachment position of the fertilizer bag 4 can be arbitrarily selected.

That is, as explained in (i) above, since the attachment position of the fertilizer bag 4 is not fixed to a specific position on the outernet 3, the optimum position can be selected depending on the shape of the slope, etc. Furthermore, since the number of attachments can be easily increased or decreased, the amount of fertilizer applied can be adjusted depending on the soil quality of the slope.

(iii) Extremely effective in preventing rock falls on slopes.

That is, both inner and outer nets 2 and 3 are
Since the mesh sizes are different and the outer net 3 with a large mesh is stronger than the inner net 2, the inner net 2 mainly prevents falling rocks such as sand and pebbles and washes away surface soil. On the other hand, the outer net 3 functions as a hold down for gravel and the like.

In this example, two nets are stacked one on top of the other, but a larger number of nets may be stacked on top of each other due to the need for strength.

As is clear from the above explanation, the present invention has a two-layer structure consisting of an innernet and an outernet, and the outernet is stronger and larger than the innernet to prevent the surface layer of the slope from being washed away. The outer net is characterized in that it is formed into a mesh, and a bag containing materials necessary for vegetation is attached to the outer net by passing through the mesh of the net at appropriate pitches.

By overlapping different types of nets, the effect of retaining the earth can be enhanced. That is, since the inner net is more flexible and has a finer mesh than the outer net, it can hold down relatively small diameter soil particles and stabilize the surface layer. On the other hand, since the outer net is stronger than the inner net, it is effective in holding down debris.

Another effect is that the bag containing the materials necessary for vegetation can be easily attached.
That is, the bag is attached by taking advantage of the large mesh of the outer net and passing through the mesh at appropriate pitches, making the attachment work extremely easy. Furthermore, since the mounting position of the bag is not fixed and can be changed arbitrarily, various settings can be made depending on the topography of the slope. Furthermore, the number of attachments can be set as required, which is an excellent effect.
