In Korea, where the country is narrow and the mountains are large, it is essential to develop the slope accompanied by large-scale land construction, road construction, and railroad construction. However, since slope and rock are heterogeneously distributed on the slope, it is a natural disaster such as rainfall, which causes the slope to collapse and causes loss of valuable lives and property.
Generally, when constructing a road or a building, the rock and earth are subjected to the embankment and embankment work, and when the construction is completed, the embankment is formed by forming the slope surface. Such a slope surface may be caused by rainfall during the rainy season, This was unstable, and there was a widespread occurrence of a landslide, which is often called.

Various methods have been applied to protect slope slope such as embankment or slope surface during construction.
In the case of Seedspray, carboxymethylcellulose (CMC), which is simply a coagulation agent, is mixed with fiber as a curing agent to prevent seeds from slipping on the slope, It can not be expected to prevent surface scour phenomenon or slope slope failure.
Recently, a spraying method of applying natural fiber material such as coir net or jute mesh on sprayed seeds has been applied. However, this method is also applied to the case where the net made of a grid mesh structure is used as the surface water By penetrating into the slope soil layer, there is a limitation in prevention of scouring and prevention of slope surface loss. Particularly, in the conventional seed spraying and netting method, there is a lack of the nutrient supply method of the soil. Since the initial germination after seed spraying is delayed and the growth condition is poor, it takes a considerable period of time until the secondary slope- Have a shortcoming

Hereinafter, the present invention will be described in more detail.
It is to be understood that the invention is not to be limited to the specific embodiments but includes all changes, equivalents and alternatives falling within the spirit and scope of the invention.
Slopes and roads are formed in roads and dams due to various civil engineering works, road construction or natural disasters, and soils and rocks are exposed. These slopes are not only detrimental to the surrounding landscape, but also carry a risk of collapse or fall. These slopes should be applied by the greening method in order to prevent penetration of rainwater, loss of soil, frost, weathering. Glazing should be constructed so that the greening composition attached to the slope does not flow down from the slope, taking into account the soil, rock condition, gradient, and water availability.
Currently, in Korea, Korean traditional grasses (grasses) and grasses are mainly used as plant materials to record these slopes. In order to promote their growth, organic fertilizers such as artificial soil such as rye soil, vegetation soil, And planting seeds such as grasses or grasses to the growth-based material mixed with inorganic fertilizer, or using a method of planting grass turf, such as strips or paddy fields.
However, the recording using foreign plants such as Korean traditional grasses (grasses) and herbaceous plants is capable of rapid recording in a short period of time, but it causes aesthetic problems such as showing a heterogeneous appearance with surrounding scenery. Moreover, the use of lawns and alien plants for greening causes problems such as confusion of natural ecology.
The present invention solves the above problems by maximizing the slope-side greening and stabilizing effect of the native plants of Korea using ecological restoration greening technology and ecological transition inducing technology that promote the useful microbial activity of the soil.
In one aspect, the present invention relates to a slope surface greening method using the vegetation soil composition for slope surface greening.
Slope slope glazing method is divided into green slope slope to cover the slope slope to stabilize the slope surface, and sand slope slope method, sand slope method, vegetation mat method , Vegetation planing method, vegetation cutting method, partial slope vegetation method, vegetation lacing method, and rock slope greening method, there are natural soil, lime soil method, Texol green soil method, and wet surface soil wet method.
In the present invention, the slope surface greening method can be carried out by applying any known method to those skilled in the art.
First, the vegetation environment and construction conditions of the site to be recorded, namely soil condition, slope, climatic condition, surrounding vegetation analysis, and surrounding environment are analyzed. Next, appropriate plant material (plant species, seed mixture) and construction conditions (construction thickness) are selected. Next, a vegetation composition is prepared and applied to suit the site conditions. And, thoroughly analyze landscape and ecological transition and follow-up management.
Hereinafter, the present invention will be described in more detail.
As one specific example, the present invention relates to a slope surface greening method including the following.
(i) the attachment network installation phase;
(ii) a fixing pin fixing step;
(iii) vegetation soil containing native seeds; Microbial agents having industrial waste resolution or plant growth promoting activity; And a PCM (phase change material) as an effective component; And
(iv) Vegetation net installation stage.
One. Attachment network Installation Steps
After arranging the slope or the slope to be applied, the installation network such as a wire net, a net net, or a polyvinyl chloride (PVC) coated net is installed downward from the upper side
The step of installing an attachment network such as a wire mesh or a net network is a step of removing a foreign substance such as garbage on a slope and installing a wire mesh or net network. The slope can be a slope generated by a natural disaster such as a slope, a flood, a landslide, or the like, which is artificially damaged, such as a house, a road, a quarry and a road construction site. Specifically, the slope can be slope, slope, have.
The wire mesh may be attached after a pin capable of fixing a wire mesh such as an anchor pin or a landing pin is put on the slope surface, or the net mesh may be laid on the slope surface. The net network may be a coin net / a jute net or the like.
2. Fixing pin fixing step
After the attachment net is installed, a standard tensile force is maintained, and the crossed portion of the manganese is firmly fixed with a wire or the like so as to be fixed on a flat surface or an inclined surface. After drilling at an interval, fix it firmly with a fixing pin. The fixing pins may have different lengths of the fixing pins depending on the thickness and strength of the flat surface or the inclined surface, and the spacing is fixed at one per m < 2 >.
Optionally, additional scavenging debris may be provided.
In general, when there is a lot of water in the soil due to the softness of the soil in the tidal flats or adjacent to the river, a building or structure is constructed after the construction for improving the ground is preceded. Especially, in order to construct large-scale industrial complexes such as harbors and new ports, and to construct mass residential complexes, coastal landfills are being constructed for the efficient utilization of the national land, and complexes are built on soft grounds such as rivers where the site is relatively easy to secure. Most of these papers can not be used for the original purpose without stabilizing the ground by improving the soft ground with super soft ground which can not stably maintain the structure, so it is desirable to improve the soft ground.
Particularly, when we look at the climate characteristics of Korea, it is mostly rainy season in June, heavy rain accompanied by typhoon from July to August, so that the slope protection work that was constructed in dry season, that is, the vegetation soil, A problem occurred. That is, the high settlement used in the conventional vegetation method is used to increase the adhesive strength to the slope at the time of soil application and to accelerate the hardening time of the vegetation soil. However, when the surface of the vegetation soil is firmly hardened, , Resulting in the increase of the pore water pressure and the loosening of the vegetation soil and the vegetation so that the vegetation soil is scraped. Therefore, it is desirable to implement a method for preventing scour due to rainfall.
In addition, the conventional net has been installed to improve the adhesion strength of the vegetation soil. However, the shape of the diaphragm is generally PE coated on the thin wire (d2 ~ 4mm) and is in the form of a grid (10cm x 10cm) , The rebound ratio is high, and when the PE coating is peeled off at the time of construction, the steel wire is corroded.
In order to solve such a problem, it is preferable that a drainage material (drain board, etc.)
Particularly, as a result of installing the drainage material on the diaphragm net, the rebounding rate can be lowered due to the filling of the vegetation soil in the spacing space due to the separation from the paperboard, and even if the diaphragm is corroded, the vegetation soil can be stably attached through the adhesive force with the drainage material . Also, it is possible to prevent the increase of the pore water pressure by forcibly discharging the penetration exudation between the paperboard and the vegetation soil through the drainage material.
The drainage material of the present invention satisfies both the criteria of permeability criterion that allows the flow of water without delay and the criterion of retention criterion that prevents the flow of the clay without blocking the flow of water desirable.
The filter is installed at the lower part of the auxiliary drainage. In order to allow more water to pass, the circumference and the gap of the drainage pipe must be large. However, when the slurry is lost along the gap, piping, building settlement, Etc. may occur. Therefore, to prevent this phenomenon, the pores of the filter should be small enough to hold the protective soil.
The most reasonable approach to establish retention criteria is to compare the particle size of the particles to the apparent aperture size (O) of the filter.
Particularly, the drainage material is characterized in that the filter has a diameter of 0.04 mm and a percentage of passage of 50% or less to a diameter of 0.074 mm and a passing percentage of 50% or more so that the vegetated soil to be attached does not enter the inside of the drainage material.
For example, assuming that d = 0.04 mm and 0.074 mm pass percentage is greater than 50% based on typical particle size distribution curve characteristics,
With reference to Carroll's criteria, the effective diameter O = 0.089 mm < 2.5 (0.04) = 0.1 mm when the geotextile apparent pore size (89 [mu] m or less)
For Task Force # 25 standard application, O <0.59mm when 50% ≤ 0.074mm (0.074mm sieve percentage less than 50%); O <0.30 mm when 50%> 0.074 mm (0.074 mm sieve passage percentage 50% or more), and O = 0.089 mm <0.30 mm in geotextile appearance hole size (89 μm or less).
3. Vegetation Composition formation and spraying step
The step of forming the vegetation composition for slope side greening means the step of preparing the vegetation soil by blending the materials described below.
In another aspect, the present invention relates to a vegetation composition for slope-side greenery suitable for plant growth and use thereof.
Especially vegetation soil containing seeds according to local plant community distribution; Microorganisms capable of eliminating pollution of industrial wastes generated at construction sites; And a PCM (phase change material) capable of providing a temperature environment suitable for the activity of the microorganism as an active ingredient, and a variety of uses thereof.
strain
The composition of the present invention includes a vegetated soil containing seeds.
The soil constituting the vegetation soil is composed of a solid formed from organic matters such as minerals which are weathered rocks, residues or faeces of animals and plants, and pores between these particles, and the pores contain soil water and soil air. The soil may generally comprise soil or dredged soil resulting from excavation. For example, dredged clay or dredged sand, which is likely to be generated by dredging, granitized weathered soil that has been used in the field, or organic soil that can be utilized in a walkway and a trail
Depending on the size, it can be divided into gravel (2 ~ 5mm), sand (0.02 ~ 2mm), silt (0.002 ~ 0.02mm) and clay (less than 0.002mm) Soil in which clay and sand are appropriately mixed is preferable so that both drainage and air permeability are good.
As an example of the soil to be used, topsoil obtained by removing the foreign materials such as stones, leaves, and wood chips from sieves collected from the site can be used. These topsoil will help to harmonize well with the surrounding vegetation. Soil buried seeds (Soil Buried Seedbank) suitable for organic matter and on-site conditions are included in the topsoil, which is a useful and good base material.
The vegetation soil of the present invention preferably contains Korean native plant seeds according to the local plant community distribution.
The plant seeds are native to wild mountainous areas of Korea and can be used for seed germination and most well-tolerated plant groups. Especially, it is possible to induce conservation of ecosystem by using traditional seeds in the vicinity of the slope to harmonize with the surrounding environment.
The above-mentioned conventional seeds can be classified into two types according to the kinds of seeds, such as silkworm, chrysanthemum, mandarin, persimmon, wormwood, angiosperm, weevil berry, Hazelnut, Pine tree. Side Swallow, Rhododendron, Azalea, Araliaceae. Can be native wood or herbaceous seeds, such as bluegrass / blue-thorn / vine species, standing trees, birds, birds, birch trees, pine trees, pine trees and maple trees.
The content of the seeds contained in the composition is determined according to various conditions such as the kind of seed, the characteristics of greening paper, and the climate.
The seeds can be used by molding the pellets by appropriately mixing the seeds mixed with pellets of the standard of 50 to 80 mm. The size of the pellet according to an embodiment is a cylindrical shape and can be formed into a size of 10 to 50 mm in diameter and 20 to 80 mm in height, but the shape and size of the pellet can be freely deformed according to the application. It will be apparent to those skilled in the art that the amount of seed used and the blending ratio can be adjusted in view of the site characteristics of the application.
Optionally, the seeds may be subjected to germination / rooting promoting treatment, pest resistance and barley adaptation.
A treatment method for promoting germination comprises seeding a seed solution in any one of potassium hydroxide (KOH), sodium hydroxide (NaOH), or germination accelerating solution of NaOC1 so as to increase seed germination rate and enable short- Soaked seedlings are thinned and washed with water to induce germination promotion.
Meanwhile, the vegetated soil of the present invention may further include a compost material and / or a blended soil.
Since the composting material uses natural material wastes, the recyclability of the resources is high and the composting process can proceed in the artificial soil, so that the organic nutrients can be continuously supplied and the moisture can be supplied, thereby increasing the survival rate of the plants. . The composting material may be an organic waste or a vegetable material.
Organic wastes are food wastes which are generated in homes, restaurants, etc. and which have been depleted of foreign substances such as plastic, packaging materials and the like which have low natural decomposability. The food waste may be a dry or a wet mixture. Specifically, the food waste may be desalinated and dehydrated and finely crushed mixture, preferably composted for several days at high temperature. The organic waste may be contained in an amount of 5 to 50% by weight based on the soil. If the organic waste is contained in an amount of less than 5% by weight, it is difficult to provide sufficient organic nutrients to the plant for ecological restoration. The balance of organic / inorganic nutrients in the artificial soil may be inhibited or the adhesion of the artificial soil may be lowered.
The vegetable material has a high water absorption capacity to absorb water during the rainy season to continuously supply water to the plant and to provide organic nutrients to the ecological restoration plant by acting as a supplementary nutrient source for the organic waste. In addition, since the vegetable materials are mixed irregularly and a space is formed therebetween, it is possible to provide excellent drainage ability in the wet season.
The vegetable material may be a vegetable material generated in a restoration area, and more specifically, a plant material selected from the group consisting of wood waste chip chips, sawdust, hardwood leaves and crushed timber, seeds of shrubs and by-products of rice straw and corn, It may be a mixture of two or more. Alternatively, the vegetable material may be a dry mix or a wet mix of the above-mentioned ingredients, preferably composted. The vegetable material may be included in an amount of 5 to 30% by weight based on the artificial soil. If the amount of the vegetable material is less than 5% by weight, the recyclable effect of the vegetable waste generated in the mountain area may not be obtained. And if it is more than 30% by weight, the mixing of the constituents among the constituents during the production of the artificial soil may not be uniform, and cracking of the vegetation-based material may occur after the construction.
The blended soil can provide an environment suitable for the decomposition of the composting material, thereby increasing the amount of nutrients that can support the growth of the plant for ecological restoration, and improving the incorporation of the soil, the drainage property, the breathability, .
The blended soil may be clay, marathon, mud, peat and the like, and the blended soil may be selected in consideration of the surrounding environment of the slope and the soil condition. The clay is excellent in water absorption ability, can prevent the loss of artificial soil due to rainfall or temperature change, and is excellent in ventilation, drainage and water retention, so that the composition of the composition is increased, . By using the above-mentioned Masato, the air permeability and the drainage property are improved, and the rainwater is generated at the time of rainy season, so that the anaerobic decay of the compost material and the roots of the plant for ecological restoration can be prevented from being rotten. Finally, cow dung and peat can be used to provide inorganic nutrients such as inorganic nitrogen, and to improve bracing and water retention. It may also provide microbial habitats within the vegetation-based bed.
More specifically, the blended soil may contain 5 to 30% by weight of clay, 5 to 20% by weight of clay, 5 to 20% by weight of fowl and 5 to 20% by weight of peat with respect to artificial soil.

The microorganism preparation may be a microbial culture solution containing all or a part of the microorganisms and a mixture thereof, and the medium required for the microbial culture may be hydrocarbon enriched mineral media supplemented with LB and oil.
There are many kinds of industrial wastes generated at construction site. Most of them are found in landfill such as seabed soil, construction waste, construction waste, municipal waste (garbage), and sewage sludge. These include high concentrations of salts, methane gas, oil, chemicals and heavy metals from factories that have been torn down by redevelopment of the city.
The present invention relates to a microorganism, for example, a microorganism of the genus Pseudomonas, a microorganism of the genus Bacillus, a microorganism of the genus Seriforopsis, a genus microorganism of the genus Endomyces, a genus of the genus Saccharomyces, Including microbial agents such as Rhodococcus spp., And the like.

Microbial agent
Further, it is more preferable that the composition of the present invention further comprises a microbial agent for assisting germination and growth of seeds contained in the vegetated soil.
Plant growth-promoting rhizobacteria (PGPR), a plant-promoting rhizobacteria (PGPR) that has a beneficial effect on plants, refers to bacteria that inhabit the plant rhizosphere and promote plant growth by adsorbing to plant roots, And grows using root exudates. Soil microorganisms produce antibiotics, protect plants from plant pathogens, fix nitrogen in the air to supply plants with nitrogen sources, produce enzymes or growth regulators that regulate plant growth, It solubilizes minerals such as phosphorus to help plants to absorb easily, and also produces useful antibiotics for plants.
Specific examples include bacteria such as Bacillus, Trichoderma, Phoma, Penicillium, non-pathogenic Fusarium, and Rhizoctonia. Thereby promoting plant growth.
The method for producing the microorganism preparation may be a known method, for example, as shown in FIG. 1, includes a step of sorting and culturing the complex microorganism, an inoculating step, a culturing step, a molding step and a drying step.
Rice bran, rice husk powder, peat moss, forest product by-products, food waste, etc., which are relatively easy to obtain as a raw material for culture and have low cost, can be used by pulverizing.
The pulverized raw materials are put into a rotatory incubator and maintained in an environment suitable for microbial inoculation and inoculated with the desired strain or strain mixture. When the strain is inoculated, unnecessary microorganisms are prevented from multiplying and the degree of gelatinization is increased, so that a person skilled in the art can appropriately select the temperature at which the rapid propagation of the inoculated strain can be induced. Considering the diversity of the species and the growth rate, the medium-low culture at 20 to 40 ° C or the high-temperature culture at 85 to 95 ° C is selected and carried out. .
The inoculation strain is obtained by culturing microorganisms having seasonal and environmental diversity without artificial filtration. It is preferable to inoculate 0.01 to 0.1% by weight at the time of producing the microorganism preparation.
After the inoculation step is carried out, it is cultured at room temperature (20 to 25 DEG C) for 10 days.
It is preferable to induce the homogenization of the sustained cells by rotating the microorganism preparation at a rate of 30 to 45 rpm for 2 hours at intervals of 72 hours.
After the culturing step, 20 to 30 parts by weight of the complex microorganism solution may be added to 100 parts by weight of the cultured mixed raw material, and the mixed raw material may be selectively roughed in a predetermined shape.
The cultured mixed raw material is present in a powder phase which contains some moisture but is not suitable for molding. If the microorganism is dried or further pulverized and then dried, it is possible to complete the microorganism preparation in powder form. However, since the microorganism preparation can be optionally subjected to the molding process as required, moisture is supplied for molding. There is no particular limitation on the molding process, and if the mixed raw material is molded into a pellet shape, the molding process can be performed using a molding machine having a throughput capacity of 400 to 600 kg per hour.
The microorganism preparation or the pellet-type microorganism preparation in powder form is prepared through a drying step of drying the mixed raw material or the shaped mixed raw material.
The drying process may be any known drying method without any fear of thermal deformation of the microorganism, and there is no particular limitation. For example, hot air drying can be carried out in the range of 40 to 60 占 폚.

PCM
The composition of the present invention includes PCM microcapsules that maintain the ambient temperature constant by absorbing and releasing heat according to changes in external temperature to provide a suitable growth environment for the microorganisms.
Phase Change Materials (PCM) refers to phase change materials and can be understood as latent heat, cold storage, and heat control materials. PCM materials accumulate positive heat energy through phase change processes or emit stored heat energy and can be used to control the temperature of a substance from solid to liquid, from liquid to solid, from liquid to gas, from gas to liquid, Is a material that accumulates heat or emits heat by using a kind of physical change process that changes to. During the phase change process, all materials change their physical arrangement, not chemical reactions such as chemical bonding or formation.
Specifically, when the ambient temperature rises, the PCM absorbs and stores heat to keep the surrounding temperature cool as the liquid becomes hot. When the ambient temperature falls, the PCM emits heat to become a solid, warming the surrounding temperature . Whereby the PCM ambient temperature can be kept constant. For example, the temperature of a material containing PCM can be kept constant without being affected by external temperature, especially when the ambient temperature difference is large, such as during summer or winter.
As the PCM usable in the present invention, any known PCM such as paraffin wax, ester, and materials having a melting temperature of about -20 to 90 ° C can be selected and there is no particular limitation thereto. It will be apparent that a person skilled in the art can appropriately select and use a kind suitable for the purpose.
The phase change materials that can be used in the present invention include various organic and inorganic materials. But are not limited to, hydrocarbons (linear or branched alkanes or paraffin hydrocarbons, etc.), hydrates (calcium chloride hexahydrate, potassium fluoride tetrahydrate, ammonium alum), waxes, oils, fatty acids (Ethylene glycol, propylene glycol, tetramethylol propane, etc.), polymers (such as polyethylene, polyethylene glycol, polypropylene, and polypropylene), polyhydric alcohols Polyesters, polyacrylate co-polymer, polyethylene glycol, etc.). May be selected differently depending on the temperature condition of the environment used. Octadecane, nonadecane, icocaine, lauric acid, tetradecanoic acid, and octadecanoic acid can be preferably used.
In one embodiment, the PCM microcapsule is a mixture of a solid and a liquid having fluidity. It is preferable to have fluidity for uniform dispersion with the construction material and improvement of the individual adhesion force. In order to have fluidity, it is preferable that the solid content of the PCM microcapsule itself is maintained at 60% or less.
Therefore, in order to impart emulsification stability of the polymerization process in the production of PCM microcapsules, it is preferable to use an ethylene-acrylic acid copolymer, a styrene acrylic copolymer, a styrene maleic acid copolymer, an ethylene maleic acid copolymer, a polyvinyl alcohol, An emulsifier of a polymer having a molecular weight of from 10,000 to 800,000 can be used. This is a polymer surfactant having both a hydrophilic part and a hydrophobic part, and can form an aggregate capable of providing particle stabilization and polymerization sites in the production of microcapsules, and can simultaneously perform electrostatic stabilization.
Specifically, PCM microcapsules can be mixed at a rate of 3-6% of the dry weight of the soil. For example, when PCM microcapsules are mixed at a 5% ratio relative to the dry weight of the soil, the strength can be increased by 20-30% and the rate of decrease in strength in the freeze-thaw test can be reduced by 20%
This combination of PCM microcapsule's absorption characteristics and adhesive properties makes it possible to secure the bonding action between the soil and the environmentally friendly fireproofing, thereby preventing the surface of the pavement material from being worn when the soil pavement method is applied, Shrinkage expansion can be prevented.
If necessary, conventionally known water-soluble or usable binders may be added. The binding force of the binder, which is mostly polymeric in nature, is determined by the cohesive force of the binder and the binding force between the molecules of the binder molecular chemical acting at the bonding interface. When the adherent molecule and the binder molecule have a covalent bond, It is possible to form a binding by a hydrogen bond such as a secondary bond by the force of the Dervaus or an epoxy resin binder. As the kind of such binder, generally known ones such as epoxy resin, phenol resin, polyvinyl acetate, polyamide, polyvinyl alcohol, silicone resin, polyurethane, urea resin, melamine resin, polyolefin and rubber can be selected There are no restrictions on these binders
Due to the absorption characteristics and adhesion characteristics of the PCM microcapsules, the bonding action between the soil and the environmentally friendly solid fire can be strengthened, the temperature environment required for the microbial growth environment can be provided, and the wear It is possible to prevent the infiltration of water and to prevent the expansion and contraction of the packaging material.
On the other hand, a vegetation composition containing soil, native seed, microbial culture liquid and PCM as described above is formed, and the vegetation composition is sprayed at a high pressure on a slope or a flat surface provided with the attachment net.
At this time, the seeds of the present invention may be sprayed separately from the vegetation composition containing the other ingredients and sprayed separately or separately in the upper area. The seeds can be controlled by controlling the blending amount of the seeds according to local conditions such as climate, environment, and conditions such as the inclination angle to be sprayed and spraying time, thereby increasing the seeding rate of the seeds.
The seeds can be mixed together or separately. Seed species can be selected variously considering the soil condition of the slope and the ecosystem restoration of the surrounding environment.
The step of attaching the slope to the slope is a step of attaching the vegetation-based material layer to the slope surface by using the plant-based slurry composition for restoration of the slope ecology mixed with the seed as a dry or water wet method at the high pressure take-out part.
The thickness of the vegetation-based material layer may be 0.5 to 15 cm, and the thickness may be appropriately selected according to the soil condition of the slope, and preferably 0.5 to 6 cm.
4. Vegetation net Installation Steps
To prevent loss of seeds and soil by rainfall or external pressure, a vegetation net is installed to promote seed germination and fixed with a separate pin.
FIG. 2 shows a schematic diagram of the greening method of the present invention.
According to the slope surface greening method of the present invention, it is possible to restore eco-friendly ecology by applying a variety of native plants by a high-functional vegetation composition and to prevent the slope of the slope caused by road cutting, such as general roads and expressways, The slope can be made.
