Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a net used for vegetation, etc.

(Prior Art) Slopes cut out for construction of mountain roads, etc., are at risk of falling rocks if left unattended, so measures such as covering them with netting are usually taken. At this time, vegetation is often added to the slope in order to further increase the soil retaining effect.

The net used must have a certain degree of toughness in order to retain the earth. However, in the effort to make it tougher, it seems that the adhesion to the slope was reduced.
The original function of the earth retainer is lost. Therefore, in the past, a method was devised in which a two-layered net made of a flexible net and a strong net was layered.

(Problems to be Solved by the Invention) However, when the net is stacked in two layers, the entire net becomes bulky when folded, which is particularly inconvenient for carrying. Furthermore, in order to prevent the net from floating up on a slope, it is necessary to hold down both nets, which poses problems such as the work of holding down the net is troublesome.

Therefore, the present invention uses two types of nets, a flexible net and a strong net, but by knitting them into one piece, the bulk of the net is reduced, making handling and construction on slopes easier. I was relieved.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a main net formed of a thick string and a subnet formed of a thin string. The structure was created so that the strands intertwine and are woven into a single layer.

(Function) Therefore, since the net according to the present invention is knitted with two types of nets with different thicknesses of strings, the main net is strong and the secondary net is flexible. ing. Therefore, regardless of the size of the particles, it is possible to reliably press down on the slope.
Also, although it is composed of two types of nets, it is woven in a single layer, so the folding allowance is small and it is not bulky.

(Example) Hereinafter, an example embodying the present invention will be described in detail with reference to the drawings.

In the drawings, 1 indicates the entire network.
The net 1 consists of a main net M knitted with thick strings 2 and a subnet S knitted with thin strings 3, which are knitted in a single layer with diamond-shaped meshes out of phase. In this example, both the thick string 2 and the thin string 3 are made of synthetic fibers such as polyethylene, polyester, nylon, etc., and both have threads of approximately the same thickness. However, due to the difference in the number of threads used, the main net M side may be replaced with the secondary net S.
It is designed to be stronger than the sides.

Although not shown, a fertilizer bag may be attached to the net 1 during vegetation work on a slope.

2 and 3 schematically show how the net 1 is knitted. Thick string 2 and thin string 3 are the second
They are tied as shown in the figure. In the figure, L2,
L3 indicates the thin string 3, and L1 and L4 indicate the thick string 2. According to this, the thin strings L2 and L3 intertwine at the knot () and then move in directions that separate from each other. Then, in the middle, thick strings L1 and L
While making a knot () with 4, it intersects with the thick strings L1 and L4, and after making a knot () with the thin string 3 of the adjacent wale, they proceed in the direction of approaching each other. Then, intersect with thick string 2 again and make a knot ()
After they are made, they are tied together again. Net 1 is basically organized by repeating this pattern.

In reality, for example, the thick string 2 and thin string 3 have two inserted threads.
It is constructed by adding books one by one. An example of this is shown in FIG. 3, which corresponds to FIG. Therefore, L2,L
3 indicates a thin string, and L1 and L4 are thick strings. Of these, L2ab, L3ab and L1ab, L4ab are insertion systems, respectively.

However, in actual netting, the number of threads constituting the thick string 2 and the thin string 3 is set to be increased or decreased as appropriate depending on the purpose and the like.

Next, the effects of the network 1 having the above configuration will be specifically explained.

For example, when performing construction on a slope,
A plurality of nets 1 are combined and successively connected so as to cover the entire surface of the slope to be constructed. In this case, the net is fixed by driving anchors or the like into the slope. After that, by spraying seeds on the slope, the earth retaining work and vegetation work will be completed.

Since the net 1 of this example is a single-layer net that has two types of properties, it is not bulky when folded and is easy to carry. Since the mesh is diamond-shaped, both the main and subnets M and S can be expanded and contracted in the direction of the arrow shown in FIG. Therefore, the above-mentioned ease of carrying is further facilitated. This can be said to be a very beneficial effect when considering the slope, which is a place with poor working conditions.

Furthermore, by using a single layer net, the following effects can also be obtained. That is, in the net of this example, in addition to the knots between the thick strings 2 and the thin strings 3, there are knots between the thick strings 2 and the thin strings 3. In this regard, in the conventional double net, there are only knots between the thick strings 2 and between the thin strings 3. Therefore, if one of the strings breaks, there is a risk that the thread will unravel in the conventional net, but in the net 1 of this example, the knot between the thick string 2 and the thin string 3 prevents the thread from unraveling. It is possible to control the progress of the damage, and to prevent the spread of damage to the net as much as possible.

Of course, since two types of nets, one strong and one flexible, are used, large gravel can be held down by the main net M, and pebbles can be held down by the secondary net S, which provides high adhesion to slopes and a soil retaining effect. It also contributes to improvement.

Note that the net of this example can be used not only for vegetation, but also for a wide range of purposes, such as for ball protection in golf, baseball, and the like.

Further, in this example, the mesh is illustrated and described as having a diamond shape, but the mesh may be made into square mesh from the beginning of knitting, or may be made into square mesh by processing after knitting.

(Effects of the Invention) As is clear from the above description, since the net of the present invention is woven in a single layer from a main net formed of thick strings and a subnet formed of thin strings,
It is less bulky than conventional products and is convenient to carry and install, making it particularly suitable for work on slopes.
