Description

[Detailed explanation of the invention] This invention was used for the earthen embankment of embankments, new roads, railways, etc.
Nets that are used to cover exposed soil on slopes where residential land has been developed to prevent the soil from being washed away by rainwater, wind, etc., and to improve the germination and growth of plant seeds. It is.

Traditionally, plant seeds are sown on exposed soil on slopes such as embankments of embankments to generate plants, thereby preventing the soil from flowing away and greening the slope. If you sow seeds directly on the slope, the seeds will fall and move downwards along the slope, so the distribution of seeds will be different from the slope, with fewer seeds at the top of the slope and more seeds at the bottom. The drawback is that the soil becomes uneven and the germination of plants becomes uneven. Furthermore, it takes a considerable period of time after seeds are sown to germinate and produce plants that prevent the soil on the slope from being washed away, so during that period, the soil exposed on the slope is washed away by rainwater and plants germinate. There are drawbacks such as the fact that it can also ruin the product.

This invention eliminates these drawbacks and prevents the soil exposed on slopes from being washed away, and makes it easier for plant seeds to germinate and produce on the soil exposed on slopes, so that slopes with exposed soil can be cleaned more quickly. The purpose is to create greenery.

Next, an embodiment illustrating the soil outflow prevention net of this invention will be described.

Example 1 Coconut fibers with a brushed surface are twisted together to form a twisted string 1 with a thickness of about 5 mm, and two twisted strings 1 are arranged in parallel at an interval of about 5 mm to form one unit of warp string 2. This is a soil runoff prevention net 5 in which two twisted cords 1 arranged in parallel at an interval of about 5 mm are used as one unit of weft cord 3, and the mesh is about 40 mm vertically and horizontally.

By covering and fixing the soil runoff prevention net 5 of Example 1 over the exposed sloped soil 6 of the earthen embankment of an embankment, it is possible to prevent the soil exposed on the slope from flowing out and After covering and fixing the runoff prevention net 5 on top of the soil, when plant seeds are sown, the surface of the coconut fibers constituting the runoff prevention net 5 is brushed 4, so the seeds will fall off the runoff prevention net 5 in the raised area. The seeds land softly on the surface of the soil and fall into the comparatively large mesh of the nearby spill prevention net 5, and in places where the napping is not done 4, they fall directly into the mesh and roll down to the bottom of the slope and do not move. The distribution of seeds becomes almost uniform, which is advantageous for the germination and production of plants, and is also advantageous in terms of uniform greening of slopes.

In addition, since the coconut fibers constituting the spill prevention net 5 of Example 1 are natural fibers, the coconut fibers themselves have good water retention properties, and since the coconut fibers are twisted together, there is a large amount of space between the twisted fibers. Because water is retained in the water and the water retention property is further improved,
It is favorable for the growth of plants and for preventing dry topsoil from being washed away by wind.

In particular, in the runoff prevention net 5 of Example 1, the warp cord and the weft cord are made of two twisted cords arranged in parallel at a small interval of about 5 mm, so the effect of preventing topsoil from drying is particularly high in the small interval portions of this net. This makes it especially easy for seeds of plants that are sensitive to drought to germinate and grow in this area.
Seeds of plants that are resistant to drought can germinate and grow in the large spacing between meshes of about mm. Therefore,
By sowing a mixture of seeds of drought-resistant plants and seeds of drought-resistant plants in the area covered with the spill prevention net 5 of Example 1, the germination and growth of the plants can be improved.

Example 2 Coconut fibers with a brushed surface 14 are twisted together to form a twisted string 11 with a thickness of about 5 mm, and two twisted strings 11 are arranged in parallel at an interval of about 5 mm to form one unit of warp string 12. Also, add 3 twisted strings 11 5mm.
The soil runoff prevention net 15 is formed by using weft cords 13 that are arranged in parallel at intervals of about 100 mm to form a mesh having a mesh size of about 30 mm in length and 40 mm in width.

The soil outflow prevention net 15 of the second embodiment is also used in substantially the same manner as the net 5 of the first embodiment.

The soil runoff prevention net of this invention is made by twisting coconut fibers together into twisted strings with a thickness of about 5 mm, and by arranging multiple strings in parallel at intervals of about 1 mm to 5 mm, one unit of warp strings and weft strings is used. 20 meshes using
Since the net has a net shape of about 50 mm to 50 mm, it is possible to prevent soil runoff by covering and fixing the net over soil exposed on a slope. By sowing the seeds from above the spill prevention net, some of the seeds will land softly on the raised part of the spill prevention net, so the seeds will not scatter down the slope, and the seeds will be more stable compared to nearby spill prevention nets. Some of the seeds fall directly into the mesh, so they do not roll down to the soil on the slope and move, reducing the distribution of seeds to the soil on the slope. It is possible to sow almost uniformly and also to uniformly green the slope.

Furthermore, the soil runoff prevention net of this invention consists of multiple strings made of coconut fibers twisted together to a thickness of about 5 mm.
The net is made up of 20 to 50 mm nets, with warp and weft strings arranged in parallel at ~5 mm intervals as one unit, which is why coconut fiber, which is a natural fiber, has good water retention properties. In addition, by twisting the fibers together and creating a lot of space between the fibers, a lot of water is retained in this space, which further improves water retention. Because they are placed in parallel at intervals, the effect of preventing the topsoil from drying out is particularly excellent in the small spaced areas, making it easier for plant seeds to germinate and grow. By changing the mesh size from 20mm to 50mm, the large spacing between the meshes is suitable for seeds of drought-resistant plants to germinate and grow, making it possible to quickly revegetate slopes with exposed soil.

Since the soil runoff prevention net of this invention is made of coconut fiber, it has excellent weather resistance and corrosion resistance, so it is strong enough to prevent soil runoff over a long period of one year or more. The runoff prevention net can prevent soil runoff until the slope becomes green and stable as plant seeds germinate and grow.
