Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a vegetation net that has improved the conventional striped weave net made of chemical fibers, which has a drawback of not being able to follow the undulations of a slope, especially the concave parts. This invention relates to the invention.

Conventionally, chemical fiber nets have been widely used as erosion prevention materials or anchoring materials for seed spraying methods, but the advantages of chemical fiber nets are: ■ They are lightweight, easy to handle, and have excellent construction properties.

@If it is shielded from light, it will not corrode and its strength will not decrease. There is,
On the other hand, the disadvantages are ■The fiber itself has a lot of repetitive force, so
It is difficult to follow the undulations of the slope. @ When tensioned, the tensile strength is slightly poor. It has advantages and disadvantages. This drawback of not being able to follow the undulations of the slope is a fatal drawback for a vegetation net, and if it does not follow the undulations of the slope, the following phenomena will occur. @ The surface layer of the slope causes erosion due to rainfall.

■ When spraying seeds, the sprayed material gets on top of the net and dries, making it impossible for plants to grow. @ Plants cannot grow because they are obstructed by the net during the germination period. ■ The sprayed base material sprayed at the bottom of the net is washed away by rain because there is no retaining material.

Wire mesh is also used as a vegetation net, but wire mesh has its advantages.

■ Easy to follow the undulations of slopes because the repetitive force is weak.

@ It has tensile strength when stretched. On the other hand, as a disadvantage.

■ Fertilizer and water corrode and reduce the strength significantly in a short period of time.

@ It is heavy, difficult to handle, and has poor workability.

It has advantages and disadvantages. Considering the above, a net that combines the advantages of chemical fiber net and wire mesh would be ideal as a net for vegetation.

The present invention was invented focusing on the above-mentioned characteristics of the chemical fiber net and wire mesh.The base is a chemical fiber net, and metal wire is used as a material to weaken the repetitive force of the chemical fiber net and increase its tensile strength. It was invented because it was believed that if the metal wire was used as the thread during net knitting, the repetitive force would be weakened.

The configuration of the present invention will be explained below.

The chemical fiber thread may be made of any material such as polyethylene, nylon, vinylon, etc., and the thickness of the thread is 300 to 6.
It is about 0.00 denier.

The metal wire is plated wire, vinyl-coated iron wire, annealed iron wire, etc., and the thickness of the thread to be used as the thread is slightly thicker than that of chemical fiber thread.

1-2 metal wires are placed in the threads of these chemical fiber threads.
The net is then mixed in and knitted together using a method such as raschel knitting to form a net.

In this case, metal wires are usually mixed only in the longitudinal direction of the net when viewed from the stretching direction, but sometimes metal wires are also mixed in the transverse direction to form a striped weave.

Also, pass reinforcing ropes through this net at both ends and in the middle.

The shape of the net is 1-2cm long and 15-30mm in length, so it is packaged in a roll, and the mesh is 8-3mm wide and 10-5mm long.
0 skin.

When the vegetation net of the present invention created in this way is stretched on a slope, the metal wire will dent along the depression simply by stepping on the depression, weakening the repetitive force of the vegetation net, making the vegetation net as a whole. This allows it to be stretched along the unevenness of the surface.

As described above, the present invention is a vegetation net characterized in that a chemical fiber thread and a metal wire are twisted together to form a strand, and the strand is knitted using at least either a warp thread or a striped thread. Since the repeating force is weakened by the action of the wires, it is now possible to stretch the net along the unevenness of the slope, which is the most important aspect of a vegetation net.

Furthermore, since the base is made of chemical fiber net when light is blocked, there is no semi-permanent loss of strength.Especially in the early stages of construction when tensile strength is required, it has superior tensile strength compared to simple chemical fiber net. It is easy to handle and has excellent workability.

Therefore, if the seed spraying method is applied over the vegetation net of the present invention, the net will not wash away the sprayed substrate due to the net's locking effect and will not cause erosion, making it an ideal net for vegetation nets. was completed.
