Description

Soil for Cutting Ground and Afforestation Method Thereof}

The present invention relates to a soil for incisional surface and a greening method using the same, and more particularly, to an incisional surface soil for planting trees or flowers on the incisional surface so that the incision surface is not damaged by rainwater, and a greening method using the same. .

As the 20th century enters the 20th century, in order to construct roads that increase due to the development of transportation methods, incisions are formed on the edges of roads as the roads are cut by cutting parts of mountains, rivers, and rivers. .

These incisions cause unexpected rains due to global abnormal temperatures such as El Niño and La Niña, and as a result, about 70-80% of rainwater that falls on the incisions flows to the ground.

In this way, the rainwater flows down and part of the rainwater penetrates into the ground of the incision. The rainwater that penetrates into the incision surface becomes bulky at the weak soil, causing the landslide to collapse and cause landslides.

This disruption of the incision cuts off not only road traffic but also accidents such as vehicles being buried or overturned, resulting in accidents that cause loss of life as well as loss of life.

The soil of these incisions is excavated from rock or soil, and the soil that forms most of the soil is produced through physical, chemical and biological weathering for many years.

In addition, the main components of the soil generated from the rock includes minerals, which are the weathering products of the rock, and water, carbon dioxide, and oxygen generated during the decomposition of organics and organics formed from animal and plant debris.

Therefore, incisions such as mountains or rivers are changed to soils that plants can grow through biological weathering of soils after approximately 5 to 10 years after construction of incisions.

Such incisions are planted and planted with tubular plants, such as grass and shrubs, so as not to be damaged by heavy rains, heavy rains, etc. during the rainy season, so that the incisions surface is not collapsed or damaged.

The greening method of the incision method covers the incision surface, sowing seeds of grass and shrub plants, and then covering the thermal insulation materials such as rice straw and fiber nets to maintain humidity, so that the germinated seeds grow and grow on the incision surface. To be done.

As the greening method of the incision method, various methods are carried out. The first method is a method of spraying a mixture of seeds, fibers, pigments, and fertilizers in water, and the second method is a seed, Fiber, pigment, fertilizer, etc. are mixed and sprayed and then covered with green straw, cocoa net, jute fiber net, and the third method is to mix the soil with water in the form of dough and pressurize the high-pressure rotary pump to the incision. The method of spraying by the furnace, and the fourth method include a soil mixing machine, a super-compressor, a method of attaching by using an equipment such as an excavator.

In addition, the first method is to mix seeds, fibers, adhesives, pigments, and fertilizers in water. Such a greening method does not make greening even if the greening is on a dry cut slope when there is no rain. In addition, when heavy rain falls, a large water bone is generated, which causes the disintegration method to collapse, which does not require greening in the first method.

In addition, the second method is spraying by mixing seeds, fibers, adhesives, pigments, and fertilizers in water and then covering rice straw, cocoa net, jute, and fiber to maintain moisture. After the formation and recording, if the heavy rain falls, the soil leakage and the surface has a disadvantage of collapse.

In addition, the third method is a wet method in which water and soil are mixed and sprayed, and the product is sprayed in the dough state at the time of expensive machine and incision paper spraying, so that the soil flows down and sprays 2-3 times and the soil dries and thins. And cracking of the soil occurs.

In addition, since it uses equipment such as soil transportation vehicle, water transportation vehicle, and crane for mixing water and tanks with large capacity to transfer and spray to the incision in the state of dough, it is not only difficult to construct but also expensive equipment. The cost is increased, the work efficiency is lowered.

In addition, the fourth method is a method of compressing soil made of waste sludge, manure, and soil to rock slopes using high-pressure air force using machines such as cranes, soil mixing machines, and large compressors, resulting in high cost of equipment and oil. It is expensive and has a disadvantage of being mainly used for rock recording.

Among the existing greening methods, the first method of sowing seeds so that they are greened in the soil area at a low cost, and the second method of covering rice straw, jute, fiber, etc. after seeding are recorded. Even if the planting has taken place after ~ 5 years, if guerrilla heavy rain falls, there is a small crust and most of the surface collapses.

In addition, there is a problem in that the road surface and the embankment, such as civil engineering construction site to cut again and then greening again, there was a problem that the construction at a cost corresponding to several times the initial construction cost.

The present invention has been made to solve the above problems, an object of the present invention is to provide an incision surface soil and greening method using the same to quickly green the incision surface at low cost.

In order to achieve the above object of the present invention, the soil for cutting incision method of the present invention is 33 to 38% by weight of paper fiber, 2 to 3% by weight of moisturizer, 15 to 19% by weight of cocoite, 1 to 2% by weight of seeds, 3 to 5% by weight of animal and vegetable fibers, 7 to 8% by weight of rotten rice straw, 3 to 5% by weight of quicklime, 3 to 5% by weight of briquettes, 13 to 20% by weight of peat, 5 to 10% by weight of clay soil It is characterized by.

In addition, the greening method of the incision method of the present invention is 33 to 38% by weight of paper fibers, 2 to 3% by weight of moisturizer, 15 to 19% by weight of cocoite, 1 to 2% by weight of seeds, 3 to 5% by weight of animal and vegetable fibers, 7 to 8% by weight of rotten rice straw, 3 to 5% by weight of quicklime, 3 to 5% by weight of briquettes, 13 to 20% by weight of peat, 5 to 10% by weight of clay soil, and then mixed and compressed to produce compressed soil, 93.8-95.9% by weight of water, 0.1-0.2% by weight of wood vinegar, 2-3% by weight of adhesive, 2-3% by weight of liquid ratio to prepare a compound aqueous solution, the compound while crushing and spraying the compressed soil obtained in the compression step It characterized by consisting of the step of spraying the aqueous solution at the same time.

The compressed soil of the present invention mixes paper fibers, moisturizers, coco peat, seeds, animal and vegetable fibers, rice straw, quicklime, briquettes, peat, and clay soil.

This paper fiber is used to crush waste paper with a pulverizer, Coco pit is used as a substitute for sawdust and sludge by mixing 20% by weight of the fiber component of palm tree and 80% by weight of coco pit component, moisturizer 30 weight of toilet paper powder It is a mixture of 70% by weight of non-woven fabric, which is used to make diapers, sanitary napkins, and towels.

Seeds also use mixed sheep grass and local vegetation, with 60% by weight mixed with one or more of Perennial, Kentucky, Creeping Lad Fescue, and 40% by weight of native vegetation , Angocho, silver grass mixed with one or more) is used.

In addition, animal and vegetable fibers are mixed with jute yarn and hair cut to length of 3 ~ 5㎝, respectively, to increase soil shrinkage and cohesion and to prevent soil splitting.

In addition, rice straw is cut into 3 ~ 5㎝ long with a cutter, then mixed with ocher, sprinkled with water, and covered with vinyl, and then over one month to decay rice straw, and then dried rice straw to grow microorganisms in the soil. These straws are installed on the incision surface and change the acidification of the soil to organic compounds.

In addition, the quicklime is composed mainly of calcium oxide (CaO), and is used as a soil stabilizer as a powder powder with an alkali content of 85% or more. The briquette material is a fly ash remaining in a thermal power plant, and has a specific gravity of about 2.1 to 2.27. It has alumina (Al ₂ O ₃ ) and silica (SiO ₂ ) as its main components, and is mixed with quicklime with low specific gravity and used as soil stabilizer.

In addition, peat is pulverized collected black lignite with a grinder to contain organic matter to improve the organic content, and to improve the viscosity, clay soil is a fine particle selected by the sorting machine, peat and clay soil to suppress water evaporation and soil It is to prevent viscosity and moisture evaporation and to prevent acidification of soil.

In this way, paper fibers, moisturizers, coco peat, seeds, animal and vegetable fibers, rice straw, quicklime, briquettes, peat, clay soils are prepared and mixed to prepare compressed soil.

Their mixing ratio is 33 to 38% by weight of paper fibers, 2 to 3% by weight of moisturizer, 15 to 19% by weight of cocoite, 1 to 2% by weight of seeds, 3 to 5% by weight of animal and vegetable fiber, and 7 to 8 pieces of rotten rice straw. Compressed soil is produced by drying weight%, quick lime 3 to 5%, briquette 3 to 5%, peat 13 to 20%, clay soil 5 to 10% by weight and drying it to a size suitable for mixing and use .

In this case, the compressed soil standard used has a length of about 40 to 50 cm and a length of about 100 cm in a rectangular frame, and the compressed soil is compression molded to a thickness of 40 to 50 cm and a length of 100 cm.

In addition, when the paper fiber is less than 33% by weight, the weight of the ground soil is heavy, so it is difficult to transport the air volume, and when the paper fiber is more than 38% by weight, the soil is too swelled to weaken the cohesion.

In addition, when the cocopit is less than 15% by weight, the organic component is less than enough to supply the organic matter necessary for plant growth, and when the cocopit is more than 19% by weight, the air permeability of the plant is high, so that the rooting of the plant occurs. Cocopit is mixed with 30% by weight of paper moisturizing paper scrap and 70% by weight of moisturizer powder to prevent evaporation of the plant to prevent the rooting of the plant.

In addition, if the peat and clay soil is more than 30% by weight, the coating layer of the soil becomes thin, the ventilation is bad, and the soil becomes heavy, and if the peat and clay is less than 18% by weight, the ventilation is good and it causes obstacles to plant growth.

In addition, when the animal and vegetable fiber is 5% by weight or more, the grinding is not smoothly during the crushing and spraying of the compressed soil, and 3% by weight or less has the disadvantage of being scattered too much during the spraying of the compressed soil.

In addition, quicklime reduces heat generation by mixing fly ash, and when the quicklime is more than 5% by weight, the compressed soil is hardened and then the soil is hardened so that the root of the plant is hard to take down. We cannot supply enough.

In addition, rotten rice straw is less than 7% by weight of the soil's cohesive strength is weak, 8% by weight or less the soil's cohesion is strong.

The compressed soil is maintained in a compressed state by applying a high pressure in a state in which not only animal and vegetable fibers but also cocoite, paper fibers, etc. are injected into the rectangle during mixing.

At this time, the size of the compressed soil to be compressed is preferably compressed to a size of 40 ~ 50㎝ thickness, 100cm in length. In addition, the size of the compressed soil may be molded to a thickness of 20 to 40 cm or 50 to 70 cm, and the length of the compressed soil may be 80 to 120 cm in length. can do.

In addition, the compound aqueous solution used for the compressed soil spraying is prepared. Such a compound aqueous solution is mixed with 93.8 to 99.9% by weight of water, 0.1 to 0.2% by weight of wood vinegar, 2 to 3% by weight of adhesive, and 2 to 3% by weight of liquid ratio. These compound aqueous solutions are sprayed simultaneously at the time of compacted soil spreading.

The compound aqueous solution is sprayed without clogging from the spray nozzle when spraying the aqueous solution using clean water without foreign matters, and the wood vinegar refers to the vinegar coming from the tree, and has a strong bactericidal power and action to remove pathogenic bacteria, and promote the growth of plants. It plays a role. Such wood vinegar is diluted with water 200 times or more.

In addition, the adhesive uses biodegradable polyacrylamide, which is safe for animals and plants. The polyacrylamide is a linear structural composite that does not pollute the environment approved by the US Environmental Protection Agency. It is a surface treatment agent for temporary soil stabilization in erosion-prone areas to prevent erosion by wind and rain as it becomes more than 100 times larger transparent liquid after time. It is also used to stabilize soil and prevent dust generation.

In addition, liquid fertilizer is used to prevent acidification of the soil, and the compound aqueous solution is sprayed with liquid fertilizer so that the seeds ignite within 2 to 5 days at the temperature of 20 ~ 25 ℃ or more (mid-April to the end of September). And, by supplying enough nutrients to the ignited young plants for about 30 days, there is an advantage that the foundation for the plant to grow well is quickly formed.

Such a compound aqueous solution is sprayed like a mist, and the crushed compacted soil is not blown, the soils are instantaneously aggregated with each other, and mixed so that the spraying is possible without foreign matter. That is, the wood vinegar is 0.1 to 0.2% by weight and diluted to 100-200 times or less with water. When the adhesive is 2% by weight or less, the adhesion of the soil is weak, and when it is 3% or more by weight, the adhesion is strong and the spray is not good. And soil jungle occurs.

As such, after the aqueous compound solution is sprayed together with the compressed soil, the water vaporization inhibitor is sprayed to prevent the water from evaporating from the compressed soil.

At this time, the water-evaporation inhibitor to be sprayed is 94 to 95% by weight of water, 5 to 6% by weight of water evaporation inhibitor is sprayed on the constructed soil.

The compressed soil, compound aqueous solution, water vaporization inhibitor, etc. are all prepared and sprayed on the incision method surface while crushing a number of compressed soils compressed to 40-50 cm in diameter and 100 cm in length in a grinder.

The compressed soil thus pulverized down into the northern room as snow in the crusher, was sprayed by applying a strong wind to the crushed soil coming down.

At this time, the wind is ejected through a hose having a diameter of 150 ~ 250㎜ from the means for generating the wind, such as a blower, and the ground ground is evenly sprayed on the construction target surface.

In this way, the ground ground in the hose is sprayed on the construction target surface and the compound aqueous solution is sprayed through a separate hose, so that the soil is sprayed to a thickness of about 0.5 ~ 3 cm depending on the soil of the construction target surface in a sponge form.

At this time, when the soil to be constructed is earth and sand, the ground soil is sprayed with a thickness of about 0.5 ~ 1.5cm, and when the soil is to be ripped, the ground soil is sprayed with a thickness of about 2 ~ 4cm do.

 This compound aqueous solution prevents the grounded soil from flying and makes the soil stick to the construction surface.

The constructed soil is well ventilated and shrinkable, and after water is absorbed into the paper fiber, peat and clay soil act as a water vapor suppressor, making it the best condition for plants to grow, thus preventing clavicle in heavy rain.

At this time, the compound aqueous solution sprayed with the soil is sprayed to the extent that the ground soil is not blown, the compound aqueous solution is sprayed at 0.1 ~ 0.5ml per 1㎡.

In case of spraying more than 0.5ml of such aqueous compound solution per 1㎡, the soil has a lot of moisture and the thickness of the soil becomes thin. Therefore, soil splitting occurs, and when the aqueous compound solution is sprayed at less than 0.1mL per 1㎡, soil Not only is it poorly aggregated, but it also causes soil to fall off.

As such, after the soil and the compound aqueous solution are sprayed on the incision surface, the water vaporization inhibitor is sprayed secondly. At this time, the water-evaporation inhibitor to be sprayed is a fish bond, which is an adhesive added to the compound aqueous solution, by spraying after the compressed soil is constructed to prevent moisture evaporation, as well as sprayed to smooth the surface of the sprayed soil.

The case of the construction by putting water in the compressed soil and the conventional soil of the present invention was prepared in Table 1.

Compressed weight Construction Construction area Per 1m3 (invention) 0.05ton 350% 350㎡ Per 1㎥ (conventional construction method) 0.5ton 70% 70㎡

As described above, the weight of the compressed soil of the present invention is 0.05 ton per m 3, and the construction area is 350 m 2, so the construction efficiency is 350%. However, the weight of the soil mixed with water is 0.5 ton. The construction area has a construction efficiency of 70% because the construction area is 70 m 2, and the compressed soil of the present invention can be constructed with a construction area of approximately 5 times wider than that of the conventional method.

The present invention includes a paper fiber, coco peat, etc. in the soil to be sprayed by the incision method surface, as well as preventing the volume from being reduced as the water evaporates from the soil swollen in the water during construction, as well as preventing the soil from falling off, This split prevents cracking due to shrinkage, and since the compressed soil is sprayed onto the construction surface in a state of being crushed in a dust state, there is a useful effect of significantly reducing the construction cost compared to the existing construction method.
