Description

Soil for Cutting Ground and Afforestation Method Thereof}

The present invention relates to a soil for incision surface and a greening method using the same, and more particularly, to an incision surface soil and a greening method using the same can be recorded quickly and easily at low cost.

In general, the incision surface is formed in an inclined state at the edge of the road as a part of a mountain, a river, a river, etc. is cut to construct a road that grows due to the development of transportation with the development of civilization. Is formed.

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 is to cover the incision surface, sowing seeds of grass and shrub plants, and then covering the heat insulating material such as rice straw and fiber network to maintain the humidity to grow the germinated seeds and greening on the incision surface To be done.

Various methods are used for the greening method of the incision method, and the first method is a method of spraying a mixture of seeds, fibers, pigments and fertilizers in water, and the second method is 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 and kneading it with a high-pressure rotary pump in the incision. As a method of spraying and the fourth method, there is a method of attaching soil using equipment such as a soil mixing machine, a large compressor, an excavator, and the like.

The first method is to mix the seeds, fibers, adhesives, pigments, fertilizers in water, such a greening method is not well made even if the greening on the slope of the dry incision when there is no rain, in particular when small rain This, of course, has a disadvantage in that the incision is collapsed as a large water in case of heavy rain.

The second method is sprayed by mixing seeds, fibers, adhesives, pigments, fertilizers in water and then covered with straw, cocoa net, jute, fiber net to maintain moisture, the construction is simple but the first method Likewise, water droplets are formed in a small rain, and after raining down, there is a disadvantage in that the soil leakage and the surface collapse.

The third method is a wet method of spraying by mixing water and soil, and is sprayed in the state of kneading the product at the time of expensive machine and incision paper spraying, there is a hassle to spray the soil 2 to 3 times, the soil is As it dries, it becomes thinner and cracks occur.

In addition, since it uses equipment such as soil transportation vehicles, water transportation vehicles, and cranes for mixing large volumes of tanks and water to transfer and spray them to the incision in the state of kneading, it is necessary for construction as well as expensive construction equipment. The cost is increased, there is a disadvantage that the work efficiency falls.

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. There is a disadvantage that it is mainly used only for rock recording.

Among the existing greening methods, the first method of sowing seeds to be recorded at low cost in the earth and sand, and the second method of covering rice straw, jute, and fiber after seeding are recorded. Even though the greening has taken place over five years, if guerrilla heavy rain falls, there is a small water bone that eventually causes most of the surface to collapse.

In addition, there is a problem to cut again and then re-recording the legal surface in the civil engineering site, such as roads and embankments, there was a problem that the construction at a cost corresponding to several times the initial construction cost.

Accordingly, the present invention has been made to solve the above problems, the object of the present invention is to promote the permanent greening and stability of cancer incisions and unstable slopes generated during civil construction and to restore the original natural state The present invention is to provide an incision for the soil and greening method using the same.

In particular, by compressing the relatively light soil material after drying there is an effect that can reduce the soil transport cost and construction costs.

Hereinafter, the configuration of the present invention will be described in detail.

Compressed soil according to the present invention is used to spray paper sludge, moisturizer, peat, loess, masato, coco peat, rice straw, copper, vegetable fiber, seeds mixed with the incision.

The paper sludge is to use a crushed waste paper to a predetermined size, the moisturizer is to use a mixture of toilet paper powder, a non-woven fabric material for making diapers, sanitary napkins, cloths. While mixing the paper sludge and the moisturizer as described above, the viscous wood viscous solution is mixed to facilitate the compression.

The peat is decomposed or deteriorated due to biochemical change due to thick deposits of flower and plant or woody fluid on the basin. It is a kind of coal, but it is usually distinguished from coal by decomposing at the surface.

The loess is a deposit mainly composed of particles having a silt size of 0.002 to 0.005 mm in diameter, and along with the peat, to suppress moisture evaporation and improve soil viscosity and prevent soil acidification.

Masato is a soil formed by weathering granite, and is almost in a stone-like state, and has excellent drainage and breathability.

Soil materials consisting of peat, loess, and masato are mixed with each other and left to yard in a field such as weeds. Used to germinate.

In addition, the coco peat is 0.1cm in length, is a completely pollution-free organic particulate component extracted from the fiber extracted from the palm tree, a lot of ligrin and cellulose components are used for horticulture as a substitute for soil.

The straw is cut to a length of 3 ~ 5cm with a cutter and then mixed with ocher, sprinkled with water, and then covered with vinyl to rot for at least one month to dry and allow microorganisms to grow in the soil. These straws are applied to the incision surface and change the acidification of the soil to organic compounds.

The animal and plant fibers are used to prevent the cracking of the soil by increasing the shrinkage and cohesion of the soil by mixing the jute yarn and hair cut to 3 ~ 5cm in length, respectively.

Coco pits and rice straws are fermented and dried.

In addition, the seed is divided into seeds for the purpose of vegetation-based composition and seeds for the purpose of permanent vegetation. Here, the seed for the purpose of vegetation-based composition is a Korean herb seed (purslane, sesame, amaranth, hyacinth, forget-me-not, mugwort) or perennial Ryegrass (perennial Ryegrass), which is the earliest recorded among the seeds as the fastest greening 15 to 25% of the area is green and degenerates within 1 to 2 years after planting, and is used only to create conditions for other plants to grow naturally.

The seed for the purpose of permanent vegetation is a native vegetation culture seed consisting of trees (pine, albizia julibrissin, autumn leaves, wisteria, etc.) and shrubs (seeds, non-eagles, wildflowers, parsley, etc.), open-air frozen after soaking in water It is a seed cultured by mixing with the topsoil in a pot consisting of 3cm in diameter and 5cm in height to soften the hard shell by using a burial method. It is a seed for putting into a drilling tool to be described later.

On the other hand, in addition to the native vegetation, stream plants such as buds, willow, reeds are cut to a length of about 1 ~ 5cm and sown together with the topsoil in the drilling tool.

In this way, paper sludge, moisturizer, peat, loess, masato, coco peat, rice straw, copper, vegetable fiber, seeds are prepared in accordance with the standard and then mixed to prepare compressed soil.

Their mixing ratio is 35 to 40% by weight of paper sludge, 5 to 10% by weight of cocoite, 3 to 5% by weight of moisturizer, 5 to 10% by weight of peat, 5 to 10% by weight of ocher, 5 to 10% by weight of masato, rice straw 3 to 5% by weight, 3 to 5% by weight of copper and vegetable fiber, 2 to 4% by weight of seeds (perennial lysgras), other inevitable impurities are first dried, and secondly mixed wood vinegar with the paper sludge and moisturizer After compressing to a size of 0.5 ~ 1m ³ and cut into a cube shape having a size of 1.5 ~ 2.5cm to make a standardized mixed material. The compacted soil is then produced by compacting the remaining soil material to a size suitable for use by mixing to adhere.

At this time, the specification of the compressed soil used is made of a rectangle of 50 cm in width and 100 cm in length.

When the paper sludge is less than 35% by weight, the weight of the ground soil is heavy, so it is difficult to transport the air volume, and when the paper sludge exceeds 40% by weight, the soil is too swollen to weaken cohesion.

In addition, when the cocopit is less than 5% by weight, the organic components are insufficient in the soil, so that the organic matter necessary for plant growth cannot be sufficiently supplied, and when the cocoite is more than 10% by weight, the air permeability of the soil is high and the roots of the plants are dried. Since the phenomenon occurs, the cocoite is mixed with a moisturizer to prevent evaporation of water so that the roots of the plant do not occur.

In addition, when the peat and loess are less than 10% by weight, the air permeability of the soil interferes with the growth of the plant, and when it exceeds 20% by weight, the coating layer of the soil becomes thin, the air permeability is poor, and the soil becomes heavy. There is this.

In addition, when the masato is less than 5% by weight, the drainage and ventilation of the soil worsens, and when it exceeds 10% by weight, the drainage and ventilation is good, which hinders the growth of plants.

In addition, when the rice straw is less than 3% by weight, the cohesion of the soil becomes weak, and when the rice straw exceeds 5% by weight, the cohesion of the soil becomes strong.

When the copper and vegetable fibers are less than 3% by weight, there is a disadvantage in that they are scattered during the spraying of the compressed soil, and if the amount exceeds 5% by weight, there is a problem in that the grinding is not performed smoothly during the spraying of the compressed soil.

Soil material is mixed and mixed into a rectangular frame in a dry state, and then compressed by maintaining a high pressure.

At this time, the weight of the soil before drying is 150kg per 1m ² , the size of the soil before compression after drying is slightly swelled to 1.3m ² , and the weight per 1.3m ² increases to 160kg, but after compression 0.33 m ² The weight per 0.33m ² will be reduced to 150kg. Here, the size of the compressed soil to be compressed is preferably determined in consideration of the area of the cut surface.

As such, when the volume and weight of the compressed soil are reduced, the soil transportation cost can be reduced by 50 to 60%, thereby reducing the construction cost by 60 to 70%.

On the other hand, when the materials of the compressed soil configured as described above are sprayed on the incision method surface to prepare and use the compound aqueous solution to be sprayed to maintain excellent adhesion.

The compound aqueous solution is prepared by mixing 85 to 90% by weight of water, 1 to 3% by weight of liquid ratio, 3 to 5% by weight of adhesive, 1 to 2% by weight of water evaporation inhibitor. At this time, such a compound aqueous solution is sprayed at the same time during the spraying of the compressed soil.

Here, in the material of the compound aqueous solution, it is preferable that clean water without foreign substances is used so that the water is sprayed without clogging the injection nozzle when the aqueous solution is sprayed.

The liquid fertilizer is prepared by diluting the fertilizer in the form of powder or particles, and used to prevent acidification of the soil. By spraying the liquid solution into the compound solution as described above, the seeds are ignited within 2 to 5 days when the seeds are at a temperature of 20 to 25 ° C. or higher, and the plant can grow well by supplying sufficient nutrients to the ignited young plants for 30 days. To lay the foundation for

The adhesive uses biodegradable polyacrylamide, which is safe for animals and plants. The polyacrylamide is a fine powder, a fine powder, which does not pollute the environment approved by the US Environmental Protection Agency. When in water, it turns into a clear liquid that blows up to 100 times and is a surface treatment agent for temporary soil stabilization in eroded areas to prevent erosion by wind and rain. In addition, the adhesive is used to stabilize the soil as well as to prevent dust generation.

The water vaporization inhibitor is a piece bond, which is used to smooth the surface of the applied compressed soil while preventing moisture from evaporating from the applied compressed soil.

The compound aqueous solution made of such a material is sprayed simultaneously with the compressed soil so that the compressed soil is not blown by wind and the soil is instantaneously aggregated.

At this time, when the liquid ratio is less than 1% by weight or more than 3% by weight will cause a problem in the growth of the seed, the adhesive is less than 3% by weight of the soil adhesion is weak, if more than 5% by weight Strong adhesion, poor spraying, and soil crushing occurs.

In addition, when the moisture evaporation inhibitor is less than 1% by weight, there is a problem that the moisture evaporation is easily generated when the air permeability is good, and when the water evaporation exceeds 2% by weight, the air permeability is bad.

As such, the compressed soil compressed to a constant size in the state where both the compressed soil and the compound aqueous solution are prepared is sprayed through the first injection hole connected to the first hose while being crushed into the grinder, and the aqueous compound solution is made by the high pressure injection pump and the blower. It is preferably sprayed through a second spray nozzle connected to the second hose, it is to be sprayed together with the first spray nozzle.

At this time, the grinder is to be crushed to 0.5 ~ 2.5cm of the compacted soil, the blower uses a sleeve-type blower to improve the blowing pressure, the first and the second hose is a high pressure of 100 ~ 250mm diameter Hose will be used.

In addition, six to twelve injection nozzles are installed in the first and second injection holes, and another blower may be additionally installed in the hose connection joint to further improve the blowing pressure.

As the soil sprayed from the first injection hole is sprayed onto the construction target surface and the compound aqueous solution is sprayed through a second injection nozzle, the soil is sprayed to a thickness of 3 to 20 cm depending on the soil of the construction target surface in the form of a sponge. Are gathered.

At this time, when the soil of the construction surface is earth or sand, the ground soil is sprayed with a thickness of about 3 to 7 cm, and when the soil of the construction surface is the rock area, the ground soil is about 10 to 20 cm thick. Is sprayed.

In the case of the earth and sand area, since the original soil is secured together with the ground soil, a thickness of 3-7 cm is sufficient to sow seeds. However, in the case of a rock area, sowing seeds only by crushed soil should be able to ensure a thicker thickness than in the case of the earth and sand, preferably 10 to 20cm.

Such compound aqueous solution prevents the grounded soil from flying in the wind and the like, and causes the soil to stick to the construction target surface.

Table 1 and Table 2 show the ratio of the compressed soil and seeds according to the application area of the construction surface.

Here, the mixing ratio of the compressed soil and seeds shown in Table 1 and Table 2 is just one example of general use, and in practice, it is determined in various ways depending on the situation, such as applying in consideration of the climatic influence of the applied area. desirable.

In addition, about 4 perforations having a diameter of 1 to 3 cm per 1 m ² of the compressed soil sprayed in this way are formed.

The drilling tool is composed of a mixture of clay and a lot of clay, such as coco peat and clay, and cultured native vegetation seeds.

At this time, the top soil will be mixed with the ratio of cocoite and loess is a ratio of 5.5: 4.5 ~ 6.5: 3.5.

Here, the coco pit contains a certain amount of fiber (30%), but is mixed with loess in order to prevent drying of the plant roots in order to prevent the death of the plant.

At this time, when the root is less than the minimum mixing ratio of the loess, the roots of the plant have excellent slidability, while the drying phenomenon of the roots is severely increased. This is preferred.

In this way, the greening method of cultivating local vegetation culture seeds on the incision site of the construction site and constructing them in the drilling tool is to reduce the material cost of the high seed. When seeding without seeding, it is about 5 to 30%. It is possible to reduce the material cost of seeds by more than 80% compared to the conventional greening method with low greening rate.

On the other hand, the chord or rock area of the incision site surface is fixedly installed in order to prevent the detachment of the soil.

The ridge network interconnects the compressed soil and the incision surface to increase the cohesive force to prevent the flow of the soil in the incision surface due to rainfall or strong winds.

The rhomboid net is mainly made of PE (Poly Ethylene, polyethylene), and is made of a wire mesh having high resistance to corrosion, and the rhomboh net is fixed by anchor pins or landing pins installed at regular intervals.

Table 1 shows the results comparing the soil according to the present invention constructed as described above and the conventional soil.

As shown in Table 1, the volume of the compressed soil of the present invention when constructing a 10 cm thick soil per 1 m ² is 0.04 m ³ , so the soil weight, machine cost, and construction cost are based on 100%. Only 30%, 10% and 30% are used for the calculation, respectively, and it can be seen that the calculation is lower than the calculation value of the conventional method 1 (wet soil) or the conventional method 2 (dry soil).

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and the general knowledge in the art to which the present invention pertains without departing from the gist of the present invention as claimed in the claims. Anyone with a variety of modifications can be made, as well as such changes are within the scope of the claims.
