The present invention relates to an erosion prevention net that protects the upper part of the covering hole and prevents surface loss, thereby securing the safety of the steep slope surface and having an eco-friendly structure. In order to protect steep slopes such as railroads, railways, and tunnels, and to prevent erosion as much as possible in the environment, pre-coated constructions are lost in the state of using a hemp and a wooden pile made of coarse twine, a material that decays and decomposes on the top of the coating. The present invention relates to a method of preventing surface erosion of slopes, which is supplemented to prevent additional construction costs for additional reinstallation.

In general, in the case of the coating method, which is applied to protect the surface of the slope, the filet, the flat, the seed spraying, and the partial vegetation method are left as they are until they stick after the construction.

In addition, some loss occurs due to rain or the like to cover the surface using a tent or vinyl to prevent the loss during the rainy season.

FIG. 1 is a view showing a configuration of a covering hole provided on a general inclined surface, in which a covering hole 2 is generally provided in a constant thickness on the earth and sand surface layer 1 of the inclined surface.

2 is a view showing a situation in which the surface erosion and loss occurs during the rainy season on a general slope, when rain rains during the rainy season, rainwater penetrates into the soil surface layer (1) of the slope, as shown in the figure, The incision causes loss of loosened areas.

When using only the coating method as in the conventional method described above, when a large amount of rainwater is frequently introduced or where there is a large amount of groundwater, a part of the covering hole including the soil surface layer is easily lost due to the hydraulic pressure. When the rain is pouring, such as rainy season, the entire earth surface layer is slid, including some of the missing portion, and the collapse occurs, resulting in problems such as life and vehicle accidents.

The present invention, in order to solve the above problems, the present invention, by using an eco-friendly spigot, supporting rods and wooden piles in order to suppress the loss of the earth surface surface layer and coating hole as much as possible to add a surface to prevent the loss of steep slopes The purpose of the present invention is to provide a method of preventing the surface erosion of slopes so that safe slopes can be maintained by using ecological stalks and wooden piles as materials that can be continuously decayed and decomposed until the time when the cladding becomes active.

In order to achieve the above object, the present invention, in the surface protection method of steep slopes such as roads, complexes, embankments, railroads, tunnels, etc., the surface of the erosion of the surface during the excellent penetration by crimping the eco-friendly spigot on the coating hole And to solve the problem of the loss, while the support rod is to maintain a certain interval in consideration of the slope characteristics of steep slope, the wooden pile is used to connect the general wood with nails, the eco-friendly sack is woven using a thick twine After installing the supporting steel rod on the surface layer and the upper part of the covering hole, the ecological stalk is connected to cover the covering hole, and a plurality of wooden piles are installed therebetween to prevent sagging of the stool for maintaining the gap, and thus To decay and decay, to prevent surface erosion on slopes to provide conditions for the growth of cladding plants How to provide the ball.

Hereinafter, with reference to the accompanying drawings will be described the configuration and operation state of the present invention.

3 is a view showing the configuration of the erosion prevention net of the present invention.

A cover hole 2 is provided in the soil surface layer 1 of the inclined surface, while supporting steel bars 3 are provided at regular intervals in the soil surface layer 1, and an ecological stem between the supporting steel bars 3 is disposed therebetween. 4) is connected to cover the upper part of the covering hole, the plurality of wooden piles (5) are installed between the eco-friendly spigot (4) to prevent the squeeze and sag of the soil surface layer and the covering hole.

4 is a view showing a situation that the loss is prevented due to the erosion prevention net when the surface loss of the present invention.

If it rains during the rainy season, such as during the rainy season, rainwater flows into the interior of the slope and steep slopes using an ecological stem (4), where the relatively loose soil surface layer (1) and the cover layer (2) are the primary causes of erosion and loss. Compresses the slope to prevent loss.

Moreover, it shows the state which the plant of a covering hole spontaneously sticks between rotting bag sacks.

<Example>

1. Support steel bar

  1) Diameter: 16-25mm (depending on slope and spacing)

  2) Length: 0.7 ~ 1.0m (depending on the depth of topsoil)

2. Eco-type stools

  1) Material: coarse twine

  2) Gap spacing: Within 2mm

  3) Height: 70-100mm

3. Wood Stakes

  1) Length: 300mm

As can be seen from the above-described <Example>, the loss can be suppressed by using the simple wood pile 5 and the eco-friendly spigot 4, so that the stability of the steep slope can be more reliably maintained, By planting plants and the like on the upper part of (2) to provide an environmentally friendly surface erosion prevention net so that it can be spontaneously carried out to perform a full service life.

As shown in the lower side of FIG. 4, the supporting steel bar 3, the ecological stem 4, and the wooden pile 5 are installed at regular distances of the steep slope, and thus, the steep slopes 2, that is, the steep slope. Sliding of the soil surface layer on the slope is prevented as much as possible.

The effects according to the configuration and operation state of the present invention described above will be described.

The construction structure of the erosion prevention net of the present invention, by using the eco-type sack to compress the soil surface layer and the cover hole on the slope to obtain the effect that can solve the problems of the loss of the soil surface layer and cover hole due to rainwater and dropping of erosion Can be.                     

In addition, since the construction structure of the erosion prevention net of the present invention does not need to install a separate rainwater intrusion prevention facility even during the rainy season, such as manpower construction regardless of the steep slope slope, the construction is simple, economical and long-term stability of slope Has the effect of contributing to

In addition, the construction structure of the erosion prevention net of the present invention can be provided on the inclined slopes of roads, complexes, embankments, railways, tunnels, etc. to have an eco-friendly structure because the covering holes are spontaneously slid and little reinforcement residues remain even after sharing. .

In particular, due to the above-described reasons, it is possible to obtain an effect of providing a construction structure of the slope-erosion prevention net of the slope that can satisfy both the stability and environmental aspects of the slope.
