Description

NATURAL MIXED SOIL COMPOSITION AND THE PREPARATION METHOD THEREOF [0002]

The present invention relates to a natural formulated soil composition and a method for producing the same. More particularly, the present invention relates to a natural planted soil composition and a method for producing the same, and more particularly, And which can be applied by both wet spraying and dry spraying, and a method for producing the same.

As the rapid economic growth and industrialization accelerated, slope slopes were created in various construction or development sites such as roads and complexes. If the damaged sliced slices were left untouched, poor slopes were formed and the slopes were structurally unstable. In the case of landslides in the melting season or over time, the weathering and erosion of the slope surface rapidly progresses, resulting in the risk of rockfall and collapse. In addition, the slope caused by excavation in the forest area is affected by soil hardness, slope, , Slope direction, and so on. However, it is necessary to make ecological restoration through analysis and analysis of various factors closely related to plant growth. However, Early recording only On the results it did not match the surrounding forests and ecologically also have been made heterogeneous Corporation recorded a foreign introduction of Species centered. Although introduced shoots mainly used for slope surface greening are effective for early greening, they are not adaptable to the climate of Korea, resulting in a large number of pests and diseases, and a heterogeneous landscape. In particular, the existing methods of videotaping the cancer incision sites with the exotic introduction species alone are not satisfactory in terms of landscape and ecology. Many of the artificial soil compositions used for greening from a seed spraying method for spraying seeds on a sloped surface of a slope have been developed.

Currently, the slope greening method that is mainly used is the method of covering the rice straw and cornet after sowing by mixing simple seeds, fertilizer and pigment in the Tosa area, the artificial waste based on industrial waste such as sewage sludge and paper sludge A method of dry spraying soil with a high-pressure sprayer (spraying using self-water of artificial soil material) and spraying wet spraying of water and adhesive with artificial soil have been mainly developed and used.

For example, in Korean Patent No. 1996-10930, "Rye soil composition prepared by mixing sludge cake, pulp sludge, briquette material and pit" is described. In Korean Patent No. 1996-11616, "paper by-product, briquette, , Peat, masato, boszedetel, and organic materials ".

However, until now, artificial soil use methods have been focused on the use of low-quality low-cost materials for slope-dyed greenery composition only considering economic efficiency or focusing on composition and composition ratio of sewage sludge and paper sludge industrial waste, And the use of an excessive amount of adhesive makes it possible to prevent the formation of soil, which is a soil structure suitable for plant growth, due to the cementation phenomenon of "concretization (soil hardness of 30 mm or more)", In addition, there is an additional cost of re-construction due to deterioration of greening, deterioration of the greening continuity due to elongation of the air due to collapse, Several types of decaying anaerobes in sewage sludge Generates a lot of bacteria and odor after construction directly due to microbial activity are required, the use of environmentally friendly materials based on natural ingredients and uniform germination and continuous growth of current seeds as possible.

In addition, the dry spraying method in the construction method is spraying at a high pressure, and it is difficult to control the thickness of the conventional artificial soil greening material composition, so that it is difficult to make a thick and thin construction. In case of applying with a weak pressure for thin construction, In the wet spraying method, when the recording material composition is stirred with water and sprayed, the load of the artificial soil composition itself is increased, and when the soil is thickly applied to the slope of the rock, it flows to the lower end portion The problem of falling or dropping occurred frequently, and when the adhesive was used only for adherence, the soil was not cured and germinated, or the plant could not reach the root, resulting in poor recording. For example, greening methods developed using artificial soil such as Korean Patent Nos. 1992-10930 and 1996-11616 can be divided into a dry method and a wet method, and the thickness of the applied (spray) 7 cm, or 10 ~ 15 cm in diameter.

In order to solve these problems, it is possible to compensate for the disadvantages of the free construction thickness control, the wet spraying method and the dry spraying method suitable for the plant growth in the poor base environment of the damaged area, and the problem of the artificial soil greening material using the industrial waste as the main material There has been a constant need for a recording material composition capable of solving the above problems.

The "clay loam" is a natural soil excellent in red viscous force, which is collected in the ground. It is collected at a depth of 0.5 ~ 1m depth and has no foreign matter and germs. It has excellent surface tension and the anion property of colloidal particles It is very strong and plays an important role in binding and binding with organic matter of cations.

The above-mentioned "Masato" is a natural soil with a solid brown soil structure, which is collected in the ground. It is free from this substance and germs and is excellent in drainage and ventilation to help seed germination. .

The above-mentioned "Torryo soil" is a high-quality organic composted soil produced by complete fermentation by various enzymes and microorganisms existing in the body of earthworm, and has a high cation exchange capacity (CEC) It improves the physical and mosaic properties of soil by promoting the incorporation of soil. Also, it is rich in various useful enzymes, microorganisms and trace elements, and activates microorganisms and soil microbes that are beneficial for plant growth, thereby improving soil intellect.

The "fermented soil" contains a large amount of nitrogen components to increase initial growth after germination of seeds, and also has an excellent viscous force to increase the mixing and adhesion of the materials, thereby preventing the sliding phenomenon For example, sewage sludge, paper sludge, sawdust, and masato are mixed, and a fermentation liquid prepared by mixing molasses, soil sugar, and rice supernatant with EM stock solution (trade name, EMZONE, Korea) And 0.5 to 1 L, and the mixture is completely fermented for 30 to 60 days at a temperature of 20 to 25 ° C.

These components form organic bases that form the foundation of plant growth, have excellent moisturizing, bibbing and cation exchange capacity, and the anions of the soil particles serve as a major factor of anion binding for the epoxidation reaction

The "chaff charcoal" (or "charcoal") neutralizes acidic soil, removes harmful bacteria and viruses in the soil, removes odors in the soil, absorbs and supplies the water required for the plant, It absorbs the carbon dioxide gas generated by various microorganisms and supplies oxygen, increases the temperature of the soil, helps to activate the roots of the plant, and improves soil physical properties. In addition, it enhances the adsorption force between the composition materials, thereby promoting the anionization reaction between the anion properties of the soil and the cationic properties of the organic materials.

The above-mentioned "coco peat" is an organic material mainly composed of vegetable cellulose, which improves the soil physical properties by influencing the formation of the entrance structure of the soil. It can improve water retention, bobbing and air permeability and promote the development of the rootstock and the activity of aerobic microorganisms .

The above-mentioned "peat" is a kind of vegetable coal in which the carbonization is not fully developed due to a long age, is a natural organism which is used as a fertilizer raw material because of its low heating value and excellent organic matter. This shows the same ingredients and characteristics as those in which the leaves are sufficiently composted and serves to increase the physical properties of the composition such as air permeability and water retention after application together with the fertilizer component.

The above-mentioned "crushing tree" is a crushing of forest waste (oak, pine, etc.) to a length within 10 mm to 30 mm, and is rich in organic matter. By strengthening the binding force between the compositions by the nature of cation, It accelerates the reaction and it composts natural compost over time, and it has the effect of increasing the bibbing power of natural blended soil.

The above-mentioned "natural oriental organic composting" is an organic composting method in which organic matter provides sustained excellent nutrients to plants, activates soil microorganisms, inhibits harmful microorganisms in the soil, activates soil microorganisms such as earthworms (earthworms) It plays a role of forming a rich organic natural topsoil close to the soil. For example, it is used as a fermentation liquid together with the residues, humus, masato, and rice straw used for natural herbal materials necessary for human, , Korea) was fermented at a temperature of 20 to 25 ° C for 20 days or more using 0.2 to 0.5 L / m 3 of fermentation broth prepared by mixing molasses, soil sugar and rice flour.

Preferably, the natural herbal organic compost is completely fermented for more than 60 days after mixing with 10 to 60% by weight of natural herbal ingredients, 20 to 50% by weight of humus, 10 to 30% by weight of masato and 0 to 20% by weight of rice straw .

The "compound fertilizer" is a blend of nitrogen, phosphoric acid and carrie, which helps in the germination and growth of plants, at a weight ratio of 21:17:17, which smoothes the initial germination of the plant without polluting the soil.

The soil surface erosion stabilizer constituting the natural ground soil composition of the present invention is preferably 20 to 85% by weight of blastocyst, 10 to 70% by weight of bentonite, 2 to 5% by weight of anhydrous gypsum (CaSO ₄ ), 3 to 15% by weight of diatomaceous earth %.

The "blast furnace cement" serves as a binder for interlocking various materials and mainly comprises clay and lime (CaO) made of iron oxide (Fe ₂ O ₃ ), silica (SiO ₂ ), alumina (Al ₂ O ₃ ) . These blast furnace cements have no toxicity due to strong alkalis as compared with general cement, and improve the strength and durability of the soil to maintain long-term stability in the soil. In addition, the calcium hydroxide produced by hydration reaction of cement under normal temperature and normal pressure makes alkaline cement admixture and gradually neutralizes the acidified soil.

The "bentonite" is extremely fine grained clay which is formed by decomposing the glass component of the volcanic ash and has a very strong point. When the volcanic eruption occurs, the volcanic ash and tuff deposits on the seabed are altered by the rocks for millions of years or tens of millions of years It is a clay mineral that is swelled rapidly when it comes into contact with water. It has the characteristic that the volume expands to several times or several times its volume. When it comes into contact with water, it forms a viscous gel or colloid solution and its ion exchange capacity and surface area are very large. great.

The above-mentioned "diatomaceous earth" is a mineral, physically and chemically stable inorganic material mostly made of amorphous silica, and reacts with water to promote aggregation. Also, it is porous, lightweight, excellent in breathability, water retention, and bending strength, and has a property of slowly releasing nutrients it has, which is useful for soil erosion prevention and plant growth.

The above-mentioned "anhydrous gypsum (CaSO ₄ )" dissolves in water and dissociates to form calcium hydrate, which coagulates with the bentonite component to prevent erosion.

In addition, the soil entanglement activator constituting the natural ground soil composition of the present invention is preferably an organic polymeric compound which is an environmentally friendly polymer compound based on poly acryl amide, and is used in an amount of 0 to 5 wt% for dry mounting, 0.5 To 3% by weight may be mixed and used.

The above-mentioned "organic polymer" plays an important role in enhancing the physical properties of the soil of the natural blended soil through a high-order grafting reaction between the materials. The cationic nature of the organic material and the reaction So that the entangled composition is allowed to act on the slope surface. In addition, it serves to prevent erosion and spillage of the composition by controlling the usage amount according to slope inclination and spraying method (dry spraying, wet spraying).

As described above, the natural formulated soil composition according to the present invention preferably contains 40 to 80% by weight of organic soil, 19 to 50% by weight of cured soil, 0.5 to 7% by weight of soil surface erosion stabilizer, (0 to 1% by weight for dry mounting and 30 to 60% by weight for wet mounting) are mixed and sufficiently stirred to be sludged with a composition having a predetermined viscosity After spraying with spraying equipment on the slope, the installation is terminated. This composition reacts with the injection at the same time as the injection, and adheres to the slope surface and is stabilized.

The natural blended soil composition of the present invention comprises 30 to 60% by weight of water during wet spraying.

The water plays an important role in the germination of plants according to the amount of usage, and plays a role of establishing the optimum vegetation base by completely reacting the physical and chemical bonds between the compositions. Depending on the usage amount, It is influenced by runoff and soil dropout, which ultimately has an important influence on plant growth.

In the present invention, the water is mixed with the natural blended soil composition in the wet spraying, so that ultimately, the natural blended soil composition of the present invention increases wetting reaction of the soil blasted soil activator during the wet construction, It does.

The "dry spraying" and "wet spraying" apparatuses used in the present invention include all conventional dry and wet spraying apparatuses that can be used to uniformly spray a mixture of the natural blended soil composition, A wet spraying apparatus or its modifying apparatus.

After the vegetation-based environmental analysis of the greening site according to the present invention, the greening method of the present invention determines the presence or absence of foundation fire (core net, foundation wire netting) according to slope inclination and soil condition, Adjust it to the most suitable thickness for growth (0.5 ~ 20cm).

The core net is fixed to a slanting surface by using a pin (φ 16 mm, L = 200 mm) using φ 3 to 5 mm (10 to 100) × (10 to 100) generally used in a slope surface greening method, And the attachment of the natural fertilizer composition, and is composted with time to be utilized as an organic compost.

According to the Design and Construction Guideline 2009. 6 of the Ministry of Land, Transport and Maritime Affairs Road slope greening construction, the wire netting is made of a wire net covered with hard vinyl chloride on a suitable wire of KSD 3552, and the wire netting is appropriately laid on the entire slope If the unevenness is severe, the landing pin should be installed so that the wire mesh is well installed in the concave area. However, when the attachment network can not be located in the middle of the spraying thickness, the attachment network is to be installed by using a piece of wood or a spacer.

Hereinafter, the present invention will be described in more detail with reference to Examples. It is to be understood, however, that these examples are provided so that the scope of the present invention is not limited thereto.

[Example 1]

As shown in Table 1, when organic soil mixed with 60% by weight of clay loam, 5% by weight of Masato, 5% by weight of Tongryong soil and 30% by weight of fermentation soil was applied to slope 1: 1 slope surface, It was found that the soil hardness increased to 29mm or higher after adhering to the slope and the soil hardness became higher and the germination remarkably decreased as the rainfall persisted, so that the germination was poor and the coverage rate was less than 15% even after 30 days passed .

The soil hardness and green coverage percentage table of Example 1 Duration (days) 5 10 20 30 40 50 60 Coverage (%) 0 0 10 15 25 35 56 Soil Hardness (mm) 20 28 30 29 28 33 30

[Example 2]

As shown in Table 2, when the organic soil was mixed with 40% by weight of clay loam, 5% by weight of Masato, 25% by weight of Taurineae and 30% by weight of fermentation soil, Although the soil hardness was lowered and the coverage rate was increased, it was found that the coverage rate was less than 30% and the initial coverage was low even after 30 days at least.

The soil hardness and green coverage percentage of the Example 2 Duration (days) 5 10 20 30 40 50 60 Coverage (%) 0 3 15 30 45 50 72 Soil Hardness (mm) 18 25 28 27 28 29 27

[Example 3]

As shown in Table 3, when 20 days have elapsed as shown in Table 3, the organotiton blended with 30% by weight of clay loam, 30% by weight of Masato, 10% by weight of Tongryuto and 20% To 35%, and the soil hardness was less than 24mm, which is suitable for plant growth.

Therefore, as can be seen from Examples 1 to 3, when the amount of the clay loam and the fermented soil having a high viscosity were increased, the soil hardness was increased and the initial coverage rate was low as in Examples 1 and 2, The mixing ratio of the clay soil which can increase the hardness of the soil by increasing the viscosity of the highly effective silage and the high viscosity and the mixing ratio of the example 3 in which the amount of the fermented soil is reduced and the organic matter-rich soil is appropriately blended is suitable for soil hardness and plant growth I could see.

[Example 4]

The natural oriental organic compost was prepared by complete fermentation for 60 days or more after mixing with 10 ~ 60% by weight of natural herbage material residue, 20 ~ 50% by weight of humus, 10 ~ 30% by weight of Masato and 0 ~ 20% of rice straw.

[Example 5]

10% by weight of natural oriental organic compost produced in Example 4, 5% by weight of chaff charcoal (charcoal), 30% by weight of coco peat, 9% by weight of peat, 15% by weight of rice straw, 30% by weight of crushed wood, As shown in Table 4, the average soil acidity (pH) was good at 6.2, but the average electric conductivity (EC) was as high as 1.0 d / S 1.8 as shown in Table 4. As a result, And less than 25% when 30 days have elapsed.

The pH, EC, and green coverage percentage of Example 5 Duration (days) 5 10 20 30 40 50 60 Coverage (%) 0 8 19 25 42 63 77 Soil acidity (pH) 6.4 6.1 6.0 6.2 6.2 6.3 6.1 Electrical Conductivity (EC) 1.9 1.8 1.7 1.6 1.7 1.8 1.8

[Example 6]

10% by weight of rice husk charcoal (charcoal), 20% by weight of coco peat, 9% by weight of peat, 10% by weight of rice straw, 30% by weight of crushed wood, 1% by weight of compound fertilizer, 20% by weight of natural oriental organic compost produced in Example 4, As shown in Table 5, the average soil acidity (pH) was good, the average electric conductivity (EC) was less than 1.0 d / S, and the coverage rate At least 30 days have elapsed.

The pH, EC, and green coverage percentage of Example 5 Duration (days) 5 10 20 30 40 50 60 Coverage (%) 0 14 26 37 54 71 84 Soil acidity (pH) 6.4 6.3 6.2 6.2 6.3 6.1 6.3 Electrical Conductivity (EC) 0.8 0.9 0.9 0.8 0.7 0.7 0.7

[Example 7]

A mixture of 30% by weight of natural herbal organic compost produced in Example 4, 20% by weight of chaff charcoal (charcoal), 20% by weight of coco peat, 4% by weight of peat, 5% by weight of rice straw, 20% by weight of crushed wood, As shown in Table 6, the average soil acidity (pH) was good to be less than 6.5, the average electric conductivity (EC) was less than 0.7 d / S, and the green coat coverage Was at least 40% when at least 30 days had elapsed.

The pH, EC, and green coverage rates of Example 7 Duration (days) 5 10 20 30 40 50 60 Coverage (%) 2 18 29 41 59 76 92 Soil acidity (pH) 6.6 6.4 6.5 6.4 6.4 6.3 6.3 Electrical Conductivity (EC) 0.8 0.7 0.7 0.6 0.6 0.7 0.6

Therefore, as can be seen from Examples 4 to 6, it can be seen that when the amount of natural herbal organic compost and rice husk charcoal is increased, the soil pH is increased, but the initial germination and coating coverage is improved. However, in Example 7, there was no significant difference between the initial germination rate and the coating coverage rate as compared with Example 6, and the material cost cost was increased. Therefore, the mixing ratio of Example 6 was inefficient in terms of economy, It can be seen that it is appropriate.

[Example 8]

The natural blended soil composition of the present invention, which was prepared by mixing 40 wt% of organic soil, 50 wt% of cured soil, 7 wt% of soil surface erosion stabilizer, and 3 wt% of soil soaking agent, was applied to slope 1: 1 slope 1 m x 1 m As shown in Table 7, the average soil hardness was 22 mm, and the average soil pH (pH) was 6.4 and the average electric conductivity (EC) was 0.8 d / S It was found that the coating coverage rate was over 30% after at least 30 days.

Therefore, as can be seen from Examples 8 to 10, the blending ratio of the organic soil, cured soil, soil surface soil erosion inhibitor, and soil soaking agent is the most reasonable in terms of soil physical properties and plant germination growth .

[Example 11]

The mixture was mixed at a ratio of 40% by weight of the natural formulated soil composition prepared in Examples 8 to 10 and 60% by weight of water, and a 1 m x 1 m square was formed at a slope of 1: 1 slope and a thickness of 5 cm was applied. As a result, there was a phenomenon in which the adhesive force between the materials of the composition was insufficient and flowed down or dropped off after attaching to the slope, and the soil hardness was low at the early stage of adhesion, Soil hardness increased and plant germination and coating rate were low.

[Example 12]

The mixture was mixed at a ratio of 60% by weight of the natural formulated soil composition prepared in Examples 8 to 10 and 40% by weight of water, and a 1 m 占 1 m square was formed on a slope of 1: 1 slope and applied to a thickness of 5 cm. As a result, the ratio of the natural fertilizer was increased and the ratio of the amount of water was lowered. As a result, the entraining reaction between the materials was promoted and stably adhered to the slope. The soil hardness was less than 22 mm and the soil erosion did not occur. Showed excellent germination and growth.

[Example 13]

The mixture was mixed at a ratio of 70% by weight of the natural compounded soil composition prepared in Examples 8 to 10 and 30% by weight of water, and a 1 m x 1 m square was formed at a slope of 1: 1 slope and applied to a thickness of 5 cm. And the soil hardness was stable to less than 23 mm and soil erosion did not occur. However, since the viscosity of the composition was higher than that of Example 12, the workability of spraying was poor, It was found that the period of early germination and covering was late and the amount of material used was increased and the economic efficiency was low

Therefore, as can be seen from Examples 11 to 13, the combination of the natural blended soil composition and the water of Example 12 was found to be excellent in slope adhesion, soil hardness, erosion resistance, and germination and greening coverage rate And it was found to be most effective.

[Experimental Example] Test construction

Using the natural blended soil composition of the present invention, basic stabilization fire installation and maintenance test was carried out at Hangil slope test pond in Gyeonggi-do, Korea.

The ground slope of the slope slope is composed of sandy to rocky slope, slope of slope of 1: 0.7 or less, and a core net installation test point and a wire net installation test slope are installed on slope slope of Masato, weathered rock and granite rock. The slope was fixed with a landing pin (φ16mm, L = 200mm), and the arm area was fixed by using an anchor pin (φ16mm, L = 300mm) after drilling.

The foundation wire net test was fixed by using anchor pins (φ16mm, L = 300mm) after drilling. As a plant for greening, mixed seeds mixed with herbaceous trees and woody trees were used in all experimental groups.

The mixed seeds of the natural blended soil composition of the present invention (40 to 80% by weight of organic soil, 19 to 50% by weight of cured soil, 0.5 to 7% by weight of soil surface erosion stabilizer, 0 to 3% by weight of soil- 5cm, weathered rocks 10cm, and rock blasting rocks 20cm thick were sprayed using a dry jet system, and no basic stabilizer was installed for each soil as a control.

As shown in the following Table 13, in the installation test of the cornets, the Masato test was excellent in recording without dropping and loss of soil, and in the weathered and blasted rocks, some of the cornets were damaged or the soil was removed, . In the basement wire netting site, all of the soil of Masato, weathered rock, and blasted rock was good without dropping out of the soil. In the control, all of the soil of Masato, weathered and blasted rocks were dropped and the greening was insufficient.

Therefore, in the Masato area, there is no dropout of the soil in both the core net installation and the foundation wire net installation area, and the coverage rate of greening is excellent. Considering the greening quality and economical construction, it is preferable to install a cornet on the slat surface of 1: 0.7 or less , Weathered rocks, and granite rocks. Also, it was found that the growth of plants was excellent in the test area where the maintenance was not properly performed.
