The present invention relates to a vegetation block, and more particularly, to fix / install a plurality of vegetation blocks for greening consisting of a geotextile layer, a cotton fiber mat layer, a geogrid network and a germinated layer on the inclined surfaces formed on the roadside and riverside, the cotton fiber mat layer By stabilizing the soil layer of the slope through the root system of the vegetation plant in the plant, it relates to a vegetation block for slope greening that can maintain the state of the natural slope without artificial feeling even after construction.

Recently, due to the rapid development of urbanization, industrialization, and leisure industry, a huge area of land is required, and the development of the mountain is actively progressed to reduce such land shortages, and also to prevent the flood protection of rivers and the overflow of river waters during rainy weather. Embankment construction is being done actively.

However, since slopes and embankments take the form of earth and sand that eliminates the rooting of vegetation roots, they not only cause ecological problems and damage the surrounding landscape, but also have high potential for earth and earth collapse. .

It is important that the greening of slopes to compensate for these problems is done as early as possible to help herbaceous growth and to prevent soil collapse in rainfall. Accordingly, one of the general slope greening methods are constructed in the form of blocks.

That is, as shown in Figure 1 by making the concrete in the form of a block 10 and fixing it with an anchor bolt on the slope, to prevent the outflow of the soil on the inclined surface as well as between the block 10 and the block 10 This is to allow various plants to plant.

However, when the concrete product is installed on the inclined surface, there is a problem that not only contaminates the soil or river water by the material properties of the concrete, but also exposes the concrete surface to the outside to artificially build a feeling.

In order to solve this problem, a recent greening technique is biotechnological greening. In other words, biotechnological greening mainly uses living plants to protect the soil layer from slopes from various erosion factors (snow, wind, water). It is assumed that plants can achieve technical effects such as building materials. (Germany), biological engineering (UK)] (Schiechtl, 1958, Schlueter, 1986).

This biotechnological greening method is distinguished from the conventional greening method in that it restores the environment destroyed by vegetation plants in terms of the engineering function of the plant rather than the landscape. The scope of application can be widely applied in natural environments and artificially created urban spaces that require engineering and ecological functions as well as cut and fill surfaces.

One of these biological greening methods forms a seed germination layer in which seeds are distributed on the surface of a slope, and then processes the palm or coconut fibers in a mat form on the seed germination layer to cover the seed germination layer so that the plant can grow. It would be.

However, when the palm fiber or coconut fiber is covered on the inclined surface as described above, corrosion not only lasts for a long time, but when wet or wet in rainy weather, red leachate is generated, thereby causing environmental pollution and environmental damage.

The present invention has been made in view of the problems with the conventional greening method of the slope, the purpose is to stabilize the soil layer of the slope through the root system of the vegetation plant in the vegetation block for slope greening, natural-friendly without artificial feeling even after construction A vegetation block for slope recording is provided to maintain the state of the inclined surface.

In addition, another object of the present invention is excellent in moisture moisturizing ability in the section of the components of the vegetation block for the slope green vegetation is made, by forming a cotton fiber mat layer without the discharge of contaminants in the corrosion process after construction, germination In addition to providing sufficient moisture to the seeds of the process, it provides a vegetation block for slope greening, in which the temperature rises during the corrosion process so that the plant can achieve a good vegetation condition for reproduction.

In addition, another object of the present invention is that the vegetation block for greening provides a germination layer in which fecal soil and charcoal without fertilizer component are mixed thereon to allow microorganisms to reproduce in the soil layer of the inclined surface, thereby increasing the germination rate of seeds and plants. It provides a vegetation block for slope recording to activate the activity of the slope.

The present invention for achieving the above object

In the vegetation block for recording the inclined surface of the incision support generated during road construction and river construction and to prevent the loss of earth and sand to create a nature-friendly environment,

Geosynthetic layer is formed to a suitable size by using a material having corrosion resistance and permeability to contact the soil surface of the inclined surface, and a mixture of paper pulp and seeds is coated on the surface of the geotextile layer, so that moisture is applied to the seeds. A layer of cotton fiber mat for nourishing the seeds by the corrosion effect after construction with the moisturizing ability to be supplied is laminated in the same size, and the geotextile layer is fixed together with the cotton fiber mat layer on top of the cotton fiber mat layer to improve durability. Geogrid network consisting of a lattice structure is provided to form a vegetation block of a suitable size of a multi-layer structure.

In addition, it is preferable to have a structure in which a germinated layer is further laminated on the geogrid network constituting the upper surface of the vegetation block.

In addition, it is preferable to laminate the cotton fiber mat layer and the geogrid network on the geosynthetic layer to the same size, and then sew using a thread to connect each other.

Hereinafter, another vegetation block for slope recording according to a preferred embodiment of the present invention with reference to the accompanying drawings will be described in detail.

Figure 2 is an exploded perspective view showing a vegetation block for slope recording according to a preferred embodiment of the present invention, Figure 3 is a combined perspective view showing a vegetation block for slope recording according to a preferred embodiment of the present invention, Figure 4 is It is AA sectional drawing.

2 to 4, the vegetation block 100 for slope recording according to the present invention is installed to prevent the soil loss of the inclined surface formed on the road side and river side geotextile layer 110, cotton fiber mat layer 120 And a geogrid network 130.

The geotextile layer 110 is made of a plate-shaped body of the overall shape. Here, the ground fiber layer 110 is one side is in contact with the inclined surface (S) so that rain water is smoothly drained during rain, while the soil of the inclined surface (S) is easy to flow down mixed with rain water the civil fiber layer (110) To prevent the loss of sediment.

At this time, the geosynthetic layer 110 is preferably made of a material having corrosion resistance together with water permeability.

On the other hand, the cotton fiber mat layer 120 seated on the top of the geotextile layer 110 is made of a plate-like body having the same width as the geotextile layer 110. At this time, the cotton fiber mat layer 120 is coated with a mixture 121 of paper pulp 121a and seeds 121b mixed with water on the surface thereof.

Accordingly, when the vegetation block 100 for slope recording is installed on the inclined surface, the cotton fiber mat layer 120 absorbs moisture and supplies continuous moisture to the seeds 121b.

In addition, when a predetermined time after construction of the slope green vegetation block 100, the cotton fiber mat layer 120 is corroded, the heat generated at this time increases the ambient temperature, thereby promoting the germination of seeds 121b after sowing. . And if the corrosion continues as described above, the cotton fiber mat layer 120 is finally mixed with the soil without leaving any traces to supply the nutrients to the seeds (121b).

At this time, the cotton fiber mat layer 120 is made of the same size as the geosynthetic layer 110, and does not discharge the discolored leachate even after construction does not damage the natural environment.

Meanwhile, the geogrid network 130 seated on the top surface of the cotton fiber mat layer 120 is formed of a lattice structure in which a plurality of warp yarns and a plurality of weft yarns are orthogonal to each other as a polymer material.

In addition, the geogrid network 130 preferably has a larger area than the geotextile layer 110 and the cotton fiber mat layer 120 so that the outer peripheral surface thereof can be fixed to the inclined surface (S) by the pile 132 of the synthetic resin material. .

On the other hand, the germinated soil layer 140 is provided on the geogrid network 130. At this time, the germination layer 140 is made of a mixture of fecal soil and charcoal without any fertilizer components.

Here, when the germination layer 140 is laminated on the geogrid network 130, the germination layer 140 passes through the geotextile layer 110 and cotton fiber mat layer 120 to the soil layer of the inclined surface (S) Infiltrate. Accordingly, the germinated soil layer 140 forms a microbial reproductive space in the soil layer of the inclined surface S, promotes germination and increases the germination rate of the seeds 121b, and activates the slidability of the germinated plant.

At this time, the plant rooted in the inclined surface (S) through the civil fiber layer 110, so that the vegetation block 100 for greening by the root system can be more firmly fixed to the inclined surface (S).

Thus, the vegetation block for slope recording according to a preferred embodiment of the present invention made of the above configuration is stabilized by the root system of the vegetation plant planted on the inclined surface and at the same time without stabilizing the soil layer of the natural environment after construction In order to maintain the state of the inclined surface, according to the series of installation relations and the resulting interactions are as follows.
