3 is an exemplary view showing experimental results for moisture content according to Examples and Comparative Examples of the present invention;
4 and 5 are photographic diagrams showing the experimental results for the embodiment of the present invention;

Green soil according to the present invention contains 5 to 15% by weight of papermaking fiber, 10 to 15% by weight of organic fertilizer, 5 to 10% by weight of fecal soil, 5 to 10% by weight of loess balls, 5 to 10% by weight of coffee powder, 5% by weight of calcium carbonate -10 wt%, Masato 15-30 wt%, sandy soil 10-20 wt%, rice husk charcoal 5-10 wt%, and zeolite 5-10 wt%.

The paper fiber is a combination of fibers of various thicknesses made from wood fibers such as pulp and newspaper paper as a raw material, and contains a large amount of air between the fibers, so it has good air permeability and serves as a long-term food source for soil microorganisms. And, since the main component is cellulose and is composed of fine polymer fibers, when mixed with water, the viscosity increases and adhesion is exerted.

The paper fiber is contained in an amount of 5 to 15% by weight, and when the paper fiber is contained in an amount of less than 5% by weight, the effect as an adhesive for binding the materials is insignificant and the base environment is weak, and the paper fiber is contained in an amount exceeding 15% by weight. In this case, it is undesirable because the hardness of the green soil increases and plant growth may be disturbed.

The organic fertilizer contains three elements of fertilizer evenly distributed and contains various trace elements necessary for plants, and is slowly decomposed in the soil layer to supply nutrients.

As the organic fertilizer, all commercially available organic fertilizer products can be used, and preferably, natural organic fertilizer made by ripening the carcasses of all plants such as fallen leaves, sawdust, and rice straw is used.

The organic fertilizer is included in an amount of 10 to 15% by weight, and when the organic fertilizer is less than 10% by weight, the function of a sufficient nutrient source for plants in a poor space becomes insignificant, and when it contains more than 15% by weight, the composting process As the porosity of green soil increases, the cohesion can be weakened, and a phenomenon in which only specific plants dominate due to excessive supply of nutrients in the initial stage can occur, so it is added within an appropriate range.

The fecal soil is soil that has undergone a fermentation process by mixing livestock excrement with soil, and the livestock excrement is an organic fertilizer that can improve a poor environment and is used as a great nutrient for plant growth. There is a difficulty in use due to the content of a large amount of moisture. Accordingly, in the present invention, fecal soil, which is a soil that has undergone a ripening process by mixing soil with livestock excrement, is used.

The fecal soil functions as an organic fertilizer in a barren environment, is used as a great nutrient for plant growth, and has a function of maintaining plant growth in a space without a soil environment such as a bedrock area.

The fecal soil is contained in an amount of 5 to 10% by weight, and when the fecal soil is less than 5% by weight, the effect of plant growth in a bedrock area without soil is insignificant, and when it is contained in an amount exceeding 10% by weight, the binding force of the vegetation composition may be weakened. It would be undesirable for

The loess ball is made by mixing clay and water and expanding it at a high temperature of 800 to 1,200 ℃ to bake it like a stone. And it has good moisturizing properties, so it not only supplies an appropriate amount of moisture and oxygen to plants, but also has a function of adsorbing excrement generated from roots to prevent decay and help root growth.

The loess ball is made of a size about the size of a pea, and preferably has a particle size of about 4 mm or less.

The loess balls are included in 5 to 10% by weight, and when the loess balls are less than 5% by weight, the breathability and moisturizing effect are insignificant, and when contained in excess of 10% by weight, root growth is weakened due to excessive oxygen supply Therefore, it is added within an appropriate range.

The coffee gourd, as an organic resource with high recycling value, contains a large amount of various organic and functional materials such as abundant fiber, lignin, caffeine, and polyphenolic compounds, as well as organic materials, and thus has a nutrient function for plant growth.

The coffee foil is included in an amount of 5 to 10% by weight, and when the amount of coffee foil is less than 5% by weight, the base environment becomes weak, and when it is contained in excess of 10% by weight, a weakening of the binding force of the vegetation composition may occur.

The calcium carbonate, which is used as a main component of calcareous fertilizer, has a function of supplying a calcium component to plants with an effect of improving the soil pH of the soil is low or close to acidification.

The calcium carbonate is contained in an amount of 5 to 10% by weight, and when the amount of calcium carbonate is less than 5% by weight, the base environment becomes weak, and when it contains more than 10% by weight, the soil becomes alkalized and the plant roots are weakened. Therefore, it is used within an appropriate range.

The massato, as soil produced by the weathering of various rocks, has excellent drainage properties and has a high oxygen content in the soil, so it has a function of preventing inhibition of plant growth due to low pressure.

The massato is included in an amount of 15 to 30% by weight, and when the massato is less than 15% by weight, the oxygen content of the green soil is lowered, and when it is contained in excess of 30% by weight, a weakening of the binding force of the green soil may occur.

The sandy soil has a high content of sand particles and clay with a clay or silt content of 15% or less and a water content of soil particles of 20% or less. , it has the function of helping plants to supply nutrients because the decomposition of organic matter is fast.

The sandy soil is included in an amount of 10 to 20% by weight, and when the sandy soil is less than 10% by weight, the ventilation becomes weak, and when it contains more than 20% by weight, the loss of nutrients supplied to the green soil is accelerated, so that the role of long-term nutrient supply is may be weakened.

The rice hull charcoal, which is made by burning rice husk in the form of charcoal, has excellent adsorption, breathability, and retention power, thereby providing an optimal habitat for effective microorganisms in the soil, thereby energizing the soil to promote root growth and plant growth, and It contains up to 30% oxygen, so that the microorganisms in the ground are active, and it is smoothly supplied to the roots during carbon assimilation of plants to induce the growth of roots and root hairs during growth.

The rice hull charcoal is included in an amount of 5 to 10% by weight, and if the rice hull charcoal is less than 5% by weight, the underlying environment becomes weak, and when contained in excess of 10% by weight, the binding force of the vegetation composition may be weakened.

The zeolite not only has a function of concentrating and recovering harmful substances or useful components in the soil, but also has an antibacterial function, and has an excellent catalyst function. In particular, the zeolite has a moisturizing power as a desiccant due to its dehydration and reabsorption properties, but the dried zeolite has a water reabsorption function and plays a functional role as a humectant.

The zeolite is contained in an amount of 5 to 10% by weight, and when the zeolite is less than 5% by weight, the underlying environment becomes weak, and when it is contained in excess of 10% by weight, a lack of moisture in the soil may occur due to an exothermic reaction. It is added within an appropriate range.

As described above, green soil according to the present invention is composed of papermaking fiber, organic fertilizer, fecal soil, loess ball, coffee powder, calcium carbonate, masato, sandy soil, rice husk charcoal, and zeolite. The function of the components is optimized and the efficiency is increased, and the greening is done by applying dry or wet to the inclined surface.

That is, the green soil according to the present invention, when the content of each component is out of the mixing range, the function as green soil becomes insignificant, the nutrients for forming vegetation and the moisture retention ability in the soil are reduced, and the binding force of the soil is reduced. As it deteriorates, weathering and thawing of the soil occur, making it difficult to apply the slope greening method.

In particular, the coffee meal, rice hull charcoal, and paper fiber have the characteristic of being decomposed in the soil over time, and when the mixing ratio is increased, the loss of the adhesion between the cultivated and artificial soil occurs due to a decrease in adhesion during the thawing period, resulting in defects. If the mixing ratio is low, the nutrient supply is insufficient in the composting process and vegetation is not formed.

Accordingly, the green soil of the present invention is effective for plant growth on a slope by optimal mixing of papermaking fiber, organic fertilizer, fecal soil, loess ball, coffee meal, calcium carbonate, masato, sandy soil, rice husk charcoal and zeolite. It induces landscape improvement and ecological function by the

In particular, the green soil of the present invention is commercialized by recycling resources thrown away as household waste or industrial waste, preventing resource waste, and reducing the cost of producing green soil, and construction costs are also reduced.

In the green soil according to the present invention made as described above, seeds are mixed and applied to the inclined surface in a dry or wet manner, so that the inclined surface is greened.

1 is a block diagram showing an inclined surface greening method according to the present invention, and FIG. 2 is an exemplary diagram showing an inclined surface greening method according to the present invention.

For example, the present invention

Pre-inspection and preparation steps for maintenance work on the slope;

After the preliminary inspection and preparation step, a jute net or natural fiber net or PVC wire mesh is installed on the slope to form a slope safety layer;

After the installation step, the multi-functional green soil is mixed with seeds and applied to a predetermined thickness on the slope to form a vegetation layer;

After the application step, the woods are sprayed to form a woody active layer is sprayed; including, but

The green soil is 5 to 15% by weight of papermaking fiber, 10 to 15% by weight of organic fertilizer, 5 to 10% by weight of fecal soil, 5 to 10% by weight of loess balls, 5 to 10% by weight of coffee powder, 5 to 10% by weight of calcium carbonate , 15 to 30% by weight of Masato, 10 to 20% by weight of sandy soil, 5 to 10% by weight of rice husk charcoal, and 5 to 10% by weight of zeolite.

The greening method made in this way has the feature of improving the viability of woody trees from which natural vegetation can be induced for a long time in the greening of slopes.

The pre-inspection and preparation step includes: a first preparation step in which the site is pre-inspected for reviewing the construction method and construction thickness according to the site environment; It includes; maintenance work for the rockfall and scour occurrence area of the construction area according to the preliminary inspection and the second preparation stage in which the construction equipment is installed.

The installation step is a step for preventing rockfall occurring on a slope, preventing loss of soil surface, and improving the slope safety of the slope. layer is formed.

For example, if the slope (vertical height: horizontal distance) of the slope is 1:1 or more, a jute net or natural fiber net is installed, and the slope (vertical height: horizontal distance) of the slope has a slope of less than 1:1. On slopes, PVC wire mesh can be applied.

That is, jute net or natural fiber net is applied to an area having a slope of less than 45 degrees based on a slope slope of 45 degrees, and an area having a slope exceeding 45 degrees (for example, slope slope 1: 0.7 or less), PVC wire mesh can be applied.

In general, the slope of the soil surface cannot be erected exceeding 45 degrees, and if the slope exceeds 45 degrees, soil loss and loss of green soil may occur due to the safety of the slope. When provided with a slope exceeding the degree, PVC wire mesh is installed to prevent the above phenomenon.

In addition, in the installation step, jute net or natural fiber net or PVC wire mesh is installed differently depending on the slope of the slope and soil conditions, and the construction thickness of green soil may also vary.

In particular, in the rock-cutting process, the slope of the slope is rapidly created for the expansion of roads and residential land, so it is necessary to install a PVC wire mesh to prevent safety accidents caused by falling rocks. When these auxiliary materials such as jute net, natural fiber net, or PVC wire mesh are installed, green soil should be installed so that the installed shape is not exposed. The mounting thickness will be different.

That is, the jute net can be applied when wet mounting at an installation thickness of less than 20 mm in the soil area, and the natural fiber net can be applied at an installation thickness of less than 50 mm in the soil area and some weathered rock areas. In addition, the PVC wire mesh can be applied at an installation thickness of 50 mm or more in a sandy area and a bedrock area.

In this case, the jute net means woven from jute, and the natural fiber net is woven from natural palm fibers extracted from coconut.

As described above, in the present invention, jute net or natural fiber net or PVC wire mesh may be installed depending on the slope, slope soil characteristics and mounting thickness, and preferably jute net or natural fiber net or, depending on the slope, PVC wire mesh is optionally applied.

In addition, the installation step includes an initial review step for installing the auxiliary material. That is, the installation of the jute net or the natural fiber net or the PVC wire mesh is selectively or complexly installed by the initial review step for the auxiliary material installation.

The slope created by the construction work requires the safety of the slope depending on the soil quality and the slope of the slope. The installation of auxiliary materials is required. When the soil hardness value is 10 mm or less, soil loss occurs, and a net made of natural materials such as jute net or natural fiber net is required to be installed. Accordingly, auxiliary materials may be selectively installed through a review.

The application step is a step in which multifunctional green soil and seeds for vegetation restoration and landscape guidance are mixed and constructed so that the vegetation layer is formed. . For example, it is preferable to mix within the range of 20 to 30 g for the silt area, 50 to 70 g for the ripping rock area, and 90 to 100 g for the blast rock area.

As the seed, known plant seeds used in the greening method may be used, and the seeds include 20 to 50% by weight of woody plants, 10 to 25% by weight of native herbs, 20 to 40% by weight of wild flowers, and introduced weeding species. It is preferable that it consists of 3 to 15 weight%.

In addition, in the application step, based on the design and construction guidelines of the Ministry of Land, Infrastructure and Transport, the seed usage standards and construction standards may be reviewed.

The spraying step is a step in which 10 to 20 parts by weight of woody trees are further sprayed based on 100 parts by weight of the seeds applied during the application step to form an active woody layer. Since it is a slow-growing plant species, after the application step is completed, additionally spraying woody trees to increase viability in damaged areas, through this, landscape improvement and natural vegetation restoration effects on the slopes of damaged areas can be further improved. At this time, the woods may be mixed and sprayed (sprayed) with air pressure or water, preferably mixed with water and sprayed. In addition, the woody active layer is not formed separately on the vegetation layer, but penetrates into the surface and inside of the vegetation layer to be formed integrally with the vegetation layer.
