Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a net body equipped with a bag body, which is extremely easy to attach a bag-like object to.

(Conventional technology) Fiber seed spraying, which has traditionally been carried out,
It is often used because it is easy to construct, but even if the slope is fertile and the slope is gentle, vegetation can grow well over a long period of time. In steep or hard areas, a phenomenon was observed in which vegetation declined in a short period of time.

Therefore, the present inventors proposed in Japanese Patent Publication No. 57-55851 that a net for preventing the sprayed material from collapsing includes a vegetation material that has a direct or indirect beneficial effect on the plants in order to make the plants flourish for a long period of time. We proposed a method of attaching a bag-like material filled with

The present invention aims to improve the net body to which the bags are attached, which is used in this construction method. Conventionally, when attaching bag-like objects to the net body, the intervals at which the bag-like objects were attached were measured one by one. The aim is to improve the problem that it was difficult to attach the bags at regular intervals and the parts where the bags were attached were easy to tear or come off, and at the same time provide a product that is more effective in preventing landslides from falling. It is something.

(Configuration of the present invention) The configuration of the present invention will be explained in detail below based on the drawings.

First, to explain the net which is the most important component of the net fitted with the bag of the present invention, the material constituting the net 1 may be made of chemical, vegetable or metallic material. The most suitable yarns are monofila or flat yarns made from chemical fibers.

This yarn is knitted using a knitting method called latselle knitting, so that the stitches are repeatedly dense and dense at appropriate intervals, but this dense part 2 is
Approximately 5 weft threads are placed in a normal first stitch, and the second stitch is used as a unit to create a dense section.
~12mm square mesh area.

The pitch in which the thinning and thinning can be repeated is 20 to 50 cm, the width is 1 to 2 m, and the length is arbitrary, but the length is about 100 m, and the reinforcing rope 4 is arranged at both ends and the center.

When this net is expanded, it appears as a horizontal striped pattern.

In this case, if you add about one weft thread to each stitch just above the horizontal striped pattern formed by making the second stitches of the net dense, it will be possible to improve the slope surface when the net is stretched. The effect of preventing landslides is more significant.

Next, to explain the bag-like object 5, the bag-like object is a bag body that has ventilation and water permeability and is made of chemical or vegetable non-woven fabric, thread, polyethylene or polypropylene warp cloth, or fabric.
It is filled with one or more types of seeds, fertilizers, water retention materials, soil improvement materials, etc. that have a direct or indirect beneficial effect on the growth of plants.

The above-mentioned bag-like objects 5 are attached to the net having the above-mentioned horizontal striped pattern using wire or vinyl-coated iron wire 6, etc., in rows or in dots.

In this case, the pitch at which the bag-like object is attached is arbitrary, depending on the situation of the slope, from 20 to 50 cm, but in any case, since the mesh exhibits a horizontal striped pattern, there is no need to measure it with a mager, so it is extremely easy to do. Can be installed.

It should be noted that the bag-like object is usually attached to a dense part of the net, but sometimes it is attached to a sparse part.

The net with the bag-like object constructed as described above is spread out on a slope and anchored using an anchoring tool.

A well-known seed spraying method is usually applied on top of this, but
When spraying a thin layer with the spray base material, the bag-like material is stretched so as to be above the net, and when spraying a thick layer, the bag-like material is stretched so as to be below the net.

(Effects of the present invention) As described above, the present invention allows the net body to have a horizontal striped pattern by repeating the opening and closing of the net body at appropriate intervals, and allows for the growth of plants in the bag body having water permeability. This net is made up of bags filled with vegetation material that has a beneficial effect directly or indirectly, and is attached at appropriate intervals, making it extremely easy to attach bags to the net. Can be installed.

Therefore, in the past, in order to attach the bag-like objects to the net, it was difficult to attach the bag-like objects at regular intervals even though it was measured each time using a mager, etc. However, the net of the present invention Since the body has horizontal stripes at regular intervals, it is possible to attach a bag-like object extremely easily without having to measure it.

In addition, if you attach a bag-like material to the dense part of the net, it will be strong, so it will not tear or come off, and if it is stretched on a slope, it will be more effective in preventing landslides than conventional ones. , it has excellent effects.
