Description

[Detailed Description of the Invention] The present invention mainly relates to a turf body designed to prevent the collapse of earth and sand on slopes.

(Conventional technology) The conventionally used turf material is one in which seeds and fertilizer are stuck between two sheets of water-soluble paper, and a chemical or vegetable net is attached to the material, or a material made from fallen cotton. Seeds and fertilizers are generally stuck between the cotton and the fallen cotton.

The sites where these turf structures are installed have traditionally been gentle embankment slopes, but in recent years, cuttings have been constructed with fairly steep slopes, and the ability to hold back earth and sand is also required.

Also, due to heavy rainfall during the rainy season or summer,
The turf body may be washed away, especially in Southeast Asia, where the turf body can be washed away in a short time due to squalls, so a turf body that has a stronger integration between the slope and the turf body is desired. It was.

In order to meet these requirements, we investigated the shortcomings of conventional turf structures and found that if the turf structure is anchored using an anchor stopper during tensioning, the anchor stop may be torn or the anchor stopper may easily come off, resulting in legal problems. The problem was that the anchoring part, which is the point of contact between the surface and the turf body, was not integrated with the slope, and this caused the turf body itself to not have the ability to hold back soil and to be washed away by rain. The time has come.

In view of the above-mentioned shortcomings of conventional tensioned turf bodies, the inventors of the present invention were researching on a tensioned turf body that would not be washed away even in the event of rain and would have the ability to prevent soil from collapsing. Focusing on this, they arrived at the present invention, believing that the drawbacks of the conventional method could be solved by making the mesh structure of the part of the anchoring device that anchors the net on the slope denser and stronger.

That is, the present invention is a turf material for preventing landslides, in which seeds and fertilizers are attached to a net in which a horizontal striped pattern is formed by repeating the opening and closing of the net at appropriate intervals.

(Configuration of the present invention) The configuration of the present invention will be explained below.

First, the net 1, which is the most important component of the landslide prevention tension turf body of the present invention, will be explained.

The material constituting the net may be chemical, vegetable, or metallic, but chemical fiber threads called monofila or flat yarns are most suitable for use.

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 arranged in a normal first stitch, and the second stitch is made into a unit to create a dense part, and the sparse part 3 is the part with a normal stitch. be.

The pitch, which repeats the spacing and spacing, is 20 to 50 cm, the width is 1 to 2 m, and the length is arbitrary depending on the manufacturing process, and reinforcing ropes 4 are arranged at both ends and the center as necessary.

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

In this case, if you add about one weft yarn to each stitch just above the horizontal striped pattern formed by making the two stitches of the mesh dense, the effect of preventing the earth and sand from collapsing on the slope will be more effective. Remarkable.

Next, we will explain the manufacturing method for manufacturing a stretched turf body for preventing landslides. First, as shown in FIG. There is a method of pasting seeds 5, fertilizer 6, soil improvement materials, etc. to make a turf material.

The second method, as shown in Figure 3, consists of 72 sheets of water-soluble paper or cotton cloth with seeds 5, fertilizer 6, soil improvement materials, etc. stuck between them, and a net with a horizontal striped pattern as a glue. Alternatively, there is a method of pasting with heat sealing.

Thirdly, as shown in FIG. 4, a cotton-like fiber cloth 8 is first attached to a net body exhibiting a horizontal striped pattern.
There is a method of pasting seeds 5, fertilizer 6, soil improvement material, etc. on top of it using a glue.

A fourth method, as shown in FIG. 5, is to attach straw grass 9 to which seeds, fertilizers, and soil improvement materials are attached to a net having a horizontal striped pattern.

Using the above four methods, the turf body for preventing landslides of the present invention, in which seeds and fertilizers are attached to the net body exhibiting a horizontal striped pattern, is completed.

The turf body for preventing landslides completed as described above has a bag body with ventilation and water permeability, seeds and
Bag-like materials 10 filled with one or more types of vegetation materials such as fertilizers and soil conditioners that directly or indirectly have a useful effect on plants are attached at appropriate intervals as shown in the cross-sectional view of FIG. In some cases.

In this case, since the net has horizontal stripes at regular intervals, there is no need to measure the intervals at which the bags are attached using a measurer, and the bags can be attached very easily.

(Effects of the present invention) As described above, the present invention has a mesh body in which a horizontal striped pattern is formed by repeating the opening and closing of the mesh at appropriate intervals.
Since the turf body is loaded with seeds and fertilizer to prevent landslides, the slope and the turf body can be firmly integrated by securing the dense portions of the net body with anchors.

Therefore, in the conventional tension grass body, the anchoring part may be torn,
The anchor anchors used to easily come off and fall off, but with the tensioned turf body of this invention, the anchor anchoring parts are dense and strong, so this problem is eliminated, and the collapse of earth and sand on the slope is prevented from occurring in the dense areas of the net. Since it can be completely shut off by the winding, it can now be used even on steep cut slopes.

In addition, even if there is a large amount of rainfall, the slope and the turf body are completely integrated at the anchorage, so the turf body will not be washed away, making it a much superior turf body compared to conventional turf bodies. I was able to provide it.
