Description

Grass mat for greening {Lawn mat for greening a slope}

The present invention relates to a grass mat for slope greening, and more particularly, to improve the surface adhesion rate of grass seeds to prevent the loss of grass seed due to decay or death, as well as to provide moisturizing and bobbying power to the soil, so the germination rate It is related to a grass mat for slope recording, which can accelerate the early germination of Korean grassgrass seeds.

As the environment emerges as an important determinant of human well-being, the size of environmental industries related to pollution prevention and purification, clean technology, and environmental restoration is growing. The global environmental market reached $ 490 billion in 1999 alone, which is about half of the global automotive market of $ 1.37 trillion, compared with telecommunications ($ 888 billion) or memory semiconductor ($ 175 billion). When there is never a small market.

Among the environmental markets, the market for environmental restoration projects is growing rapidly as the interest in environmental restoration of damaged areas is increasing all over the world.

Representative environmental restoration projects are environmentally friendly greening projects for the cut slopes and fill slopes that exist in areas where various roads, railways, river embankments, and tunnel entrances are constructed. .

Environment-friendly greening projects for these slopes include landscaping water or turf for the purpose of preventing erosion by rainwater, mitigating surface temperature changes, tying the topsoil with plant roots to suppress and mitigate frostbite collapse, aesthetic effects, and soil pollution. Planting is common.

Among them, grass is a perennial herbaceous plant that is resistant to frequent mowing and pressing, and has strong regenerative properties.

As a method of planting grass in Korea, grass turf planting methods such as a flat grass planting method using flat grasses and a green grass planting method using grasses are mainly performed. It is possible to immediately install and move to the place where the composition of the lawn is necessary, but the disadvantages of damage to the growth point of the grass roots in the process of cutting to a certain size. In addition, the turf turf has a disadvantage in that it occupies a lot of loading space when transported to the necessary place because the soil is attached to the root, and the weight is disadvantageous, and if it is formal, the surface of the lawn formed according to the amount of the root and soil is uneven.

Accordingly, a seed spray method or a method using a net or a mat has been developed and applied among vegetation methods using grass that are being carried out for an eco-friendly greening business.

First, the seed spraying method is a method of mixing the seeds of the grass and the mixed soil and spraying the slopes through a straightener to green the plant, and the construction cost is low. However, there is a problem of low germination rate in a dry climate because seeds and mixed soils are easily lost or concentrated in some areas due to the scour phenomenon of the surface during watering and rainfall. In addition, although the giants are covered for warming, moisturizing, and keeping the soil of seeds and slopes sown by the seed spraying method, the strength of the material is so low that it is difficult to prevent scouring and sliding of the surface, resulting in extremely low greening efficiency. It is true.

In the case of the vegetation method using various nets or mats, the vegetation layer made of seeds and vegetation base materials, and fabricated in the form of a mesh net using natural fiber materials such as jute and coir By covering the slope including a net to which tensile strength is imparted, it has an excellent advantage in stabilizing the slope by preventing skin scour or sliding of the slope and detaining the soil. In addition, by providing a net or mat containing a vegetation base material containing seeds and nutrients capable of germinating seeds in the net or mat, it is useful not only for incisions or cut and fill slopes, but also for greening of rock areas. It is widely applied.

1 illustrates an exploded perspective view of a conventional vegetation mat 100, and FIG. 2 illustrates a cross-sectional view of a slope in which the vegetation mat of FIG. 1 is installed.

Referring to FIG. 1, a conventional vegetation mat 100 includes a net 110 forming a bottom end of a vegetation mat to impart tensile strength, and a first vegetation layer 120 for providing a vegetation environment on the net 110. Is adhered, and the seed germination layer 130 in which seeds are scattered on the surface of the first vegetation layer 120 and embedded in an adhesive, and a second vegetation layer laminated on the surface of the seed germination layer 130 by an adhesive agent. It has a structure consisting of the ground layer 140.

The surface 200 of the slope on which the conventional vegetation mat 100 is constructed is not flat and non-uniform, as shown in FIG. 2, whereas the first vegetation layer 120 having the seeds adhered to the seeds is flat. Due to the low surface adhesion rate of the seeds, the seed germination efficiency was low even when a large amount of seeds was used because the seed was lost due to indigenous roots lost and lost or decayed between the vegetation layers.

In addition, since a considerable amount of space 60 exists between the vegetation mat 100 and the ground surface 200, there is a problem that the vegetation mat is easily dried while ventilation is performed in the space. When the grass mat 100 is dried, the moisture is evaporated, so that the plant seeds do not germinate and die.

On the other hand, the conventional registered utility model No. 20-030977 discloses a vegetation mat for slope recording using a coconut fiber net.

3 illustrates the conventional vegetation mat 300.

Referring to Figure 3, the vegetation mat 300 is composed of a seed fiber attached sheet 320 is attached to the back surface of the coconut fiber net 310 and the coconut fiber net 310 as an adhesive during construction, the The seed attachment sheet 320 is a seed 322 attached to the back of the biodegradable paper 321 by an adhesive. According to the above design, as the surface to which the seed 322 is attached is constructed to face the construction target surface, the amount of the seed 322 that has been used in a large amount can be reduced, and the germination efficiency of the seed 322 can be increased.

However, since the vegetation mat 300 covers the coconut fiber net 310, it is difficult to preserve the soil moisture of the soil to be constructed, and the seed 322 does not germinate early due to the low thermal insulation or bobbin power of the soil to be constructed. There is a problem that the recording speed of the slope is slow.

On the other hand, most of the grasses commercially used in Korea are foreign introduced species, and since they are not adapted to the domestic climate characteristics, if the careful management after the grass is not followed, the growth rapidly declines, and the environment is inconsistent with the surrounding environment. There are several problems, such as causing a problem.

In contrast, Korean grasses grow naturally in Korea, creating a harmonious environment with the surrounding environment, and warmer turf or ecological adaptation is distributed from temperate to tropical, making it more environmentally compatible than other cold grass and other warm grass. It is the best lawn for the domestic climate.

So far, research has shown that Korean turf contains Korean grass ( Zoysia). japonica Steud. ), Gold grass ( Zoysia matrella , Non-road grass ( Zoysia tenufolia ), Conger grass (Zoysia sinica), wangjandi (Zoysia macrostachya It is reported that 5 to 6 kinds of grasses are distributed.

Especially, Korean grass, Zoysia , is the most common grass in Korea. japonica Steud. ) Is originated from eastern China, Korea and Japan, and is the only grass that has both the cold resistance approaching cold grass and the resistance of other Nanji grass.

In addition, it grows well in poor soil and withstands pests, and is known as the most suitable lawn for Korea's climate because it has long-term climate safety, self-sustainability, and low wear resistance.

These grasses in Korea have a wide range of applications in Korea, and are mainly used for covering cut slopes, fill slopes, river embankments, roads, graveyards, etc., and are widely used as landscaping plants for houses and parks. In the field of golf, baseball field, etc., the range of use is gradually increasing.

However, Korean grass has a low germination rate and low greening efficiency, so its use is limited in areas where fast vegetation is required.

Therefore, the problem to be solved by the present invention is to improve the surface adhesion rate of seeds to minimize the loss of seeds, as well as to improve the moisturizing power and preservation of the soil to promote early germination of seeds, so as to have a good greening efficiency To provide a grass mat for.

The present invention to solve the above problems,

According to a preferred embodiment of the present invention, the seed of grass may be Korean grass.

In addition, the degradable resin film layer may be made of biodegradable vinyl or photodegradable vinyl.

In addition, a plurality of perforations are formed in the degradable resin film layer, the porosity of the degradable resin sheet layer may be 20 to 35%.

On the other hand, a plurality of perforations are formed in the decomposable resin film layer, the diameter of the perforations may be 5 to 7 mm, the pitch between the perforations may be 20 to 40 mm.

In addition, the jute mesh layer meanders in the horizontal direction, and a plurality of pattern forming lines arranged to have the same fragrance axis from the top to the bottom, fixing the fragrance portion of the pattern forming line, the sanding portion and the longitudinal center portion in the horizontal direction It consists of a straight line fixed, the center of the longitudinal direction of the pattern forming line may be a fragrance portion of the lower pattern forming line.

In addition, according to a more preferred embodiment of the present invention, jute rope fibers on the top of the jute mesh layer horizontally and vertically spaced at a predetermined interval and arranged in a net form by the needle punching the jute rope fibers of the bottom straw straw layer It is good to be bound with.

The grass mat for slope greening according to the present invention improves the surface adhesion rate of the grass seed, thereby preventing the loss of the grass seed due to decay or death, as well as imparting moisturizing and stabilizing power to the soil. Even germination can be promoted, which has an effect of having excellent greening efficiency.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings and embodiments, but the present invention is not limited thereto.

Figure 4 shows an exploded perspective view of the grass mat 400 for slope recording according to an embodiment of the present invention.

Referring to FIG. 4, the grass mat 400 according to the present invention includes a straw straw fabric layer 410, a decomposable resin film layer 420, a jute mash layer 430, and a seed 440 of grass.

The straw straw layer 410 constitutes the lowest layer of the grass mat 400 so as to contact the slope. A vegetation base material (not shown) is applied to the bottom surface of the rice straw fabric layer 410, and a seed 440 is attached to the bottom surface of the rice straw fabric layer 410 to which the vegetation base material is applied. This is to strengthen the adhesion of the seed 440 to the soil by using the flexibility of the straw straw 411 by constructing the grass mat 400 on the slope, the straw straw fabric 410 is directed toward the soil of the slope. to be.

Therefore, the seed 440 attached to the bottom surface of the straw straw layer 410 can be buried in the soil of the slope because it can be easily in close contact with the soil of the slope due to the flexibility of the straw (411).

A straw straw layer 410 in which a plurality of straws 411 are arranged in parallel to each other is woven using a straw straw 411 and a jute yarn 412, as shown in FIG. A plurality of dogs may be arranged to be parallel to each other, and the jute yarn 412 may be woven to intersect the plurality of rice straws 411 to have a seat shape. This is to ensure sufficient germination space of the seed 440 attached to the bottom surface of the straw straw layer 410.

Therefore, when the slope greening grass mat 400 according to the present invention is installed on the slope, the ground surface adhesion rate of the seed 440 is improved to increase the working efficiency, thereby minimizing the loss of the seed 440, and the seed. As the germination space is sufficiently secured, the seed 440 will improve the germination efficiency.

In addition, the moisturizing and warmth of the straw 411 promotes the germination and growth of the seed 440, and can overcome the drought by suppressing the water evaporation of the slope. And, the straw straw layer 410 is fermented over time to contain various organic matter and moisture necessary for the growth of plants, and have a role of neutralizing the acidified soil, which has a certain period of time, This is naturally harmless in the soil, so it is aesthetically and environmentally harmless.

A vegetation base material (not shown) is applied to the bottom surface of the straw straw layer 410. The vegetation base material is applied only to the lower surface of the rice straw fabric 410 so as not to impair the flexibility of the rice straw fabric 410. Therefore, it is possible to fill the voids present on the lower surface of the straw straw layer 410 can increase the adhesion of the seed 440 to the lower surface of the straw straw layer 410.

The vegetation base material can be absorbed in the soil forming the slope when watering melts on the slope to serve to improve the soil. As a result, it is possible to promote early germination of the seed 440, and to supply nutrients to the growth of the grass formed by the seed 440 in the long term.

The vegetation base material is a nutrient supply source for supplying nutrients necessary for germination and growth of seeds 440 to create a vegetation environment on a slope, and includes a water-soluble adhesive and a soil improving agent. Generally, the section and fill soil forming the slope is an acidic soil, and includes a soil modifier to neutralize the acidic soil, and a water-soluble adhesive to attach the soil modifier to the straw straw layer 410.

A water-soluble adhesive is included in the vegetation base material to reliably fill the pores of the straw straw layer 410, and to be absorbed in the soil to melt down during watering.

The water-soluble adhesive can be used without limitation as long as it is commonly used. For example, polyvinyl alcohol (PVA), carboxymethyl cellulose sodium (CMC), polyvinyl pyrrolidinone (PVP), hydroxyethyl cellulose medium (hydroxyethyl- cellulose medium (HEC), terra control, starch oxide aqueous solution, and the like. In order to improve the environment and germination, it is preferable to use an aqueous starch oxide.

Such a water-soluble adhesive may easily melt when watering the vegetation mat 400 to be absorbed by the soil and contribute to improving the bearing capacity of the soil, it may serve to promote the germination of the seed 440.

Soil modifiers may include activated carbon, wood vinegar or charcoal to neutralize acidic soils. This not only promotes the growth of grass and the growth of useful soil microorganisms, but also prevents the decay of the soil and contributes to controlling pests.

In addition, the soil improving agent may include a microbial agent consisting of rhizosphere microorganisms. The rhizosphere microorganism is a microorganism which stably setstles and proliferates in the rhizosphere within the growth period of grass, and grows on the surface of the seed 440 or in the soil and grows using the secretion of the seed 440 rich in carbohydrates and amino acids and at the root surface. Continued movement and proliferation along the growing roots can reduce the density of harmful bacteria and fungi in the rhizosphere, thereby reducing the disease and thus promoting the growth of grass.

In addition, the rhizosphere microorganisms produce a substance that promotes plant growth, that is, a bioactive substance, thereby promoting nutrient absorption by the roots, thereby promoting root hair growth, root and stem growth. That is, the rhizosphere microorganisms produce special bioactive substances and change the physiology of the grass in addition to the growth promoting effect by controlling the disease, thereby doubling the plant's self-defense ability by invading germs, thereby exerting the disease prevention and growth promoting effect.

Examples of rhizosphere microorganisms include Pseudomonas, Azotobacter, Bacillus, and Lysopus oligosporus. The rhizosphere microorganisms have a fast growth rate and mobility in the rhizosphere, preferring root secretions, and at the same time, as described above, It can be accelerated.

The vegetation base material may further include at least one selected from the group consisting of organic substances, fertilizers and mixtures thereof. That is, Tony, sewage sludge, paper sludge, microbial growth promoting agent and organic matter such as chaff, bark may be further included. Therefore, it is possible to supply nutrients to the growth of vegetation in the long term.

By applying the vegetation base material as described above to the straw straw layer 410, inducing early germination of seeds and shortening the growth time, it is possible to quickly create grass grass on the slope.

In addition, due to the vegetation base material it is possible to promote early germination of the seed 440 before the vegetation mat 400 according to the present invention is installed on the slope, so that the root formed after the germination of the seed 440 smoothly sticks to the ground surface. Since the seed 440 is prevented from being killed or decayed, the loss rate of the seed 440 may be reduced, and the germination rate of the seed 440 may be improved.

The decomposable resin film layer 420 is formed to cover the upper surface of the straw straw fabric layer 410 to serve as a mulching material. In other words, it prevents soil erosion, soil water retention, geothermal control, weed control, soil infectious germ prevention, soil pollution prevention.

The degradable resin film layer 420 may be made of photodegradable vinyl or biodegradable vinyl. This is because it is not only suitable for maintaining water and controlling temperature but also being environmentally friendly as it is completely decomposed into water and carbon dioxide or methane by microorganisms in sunlight or soil.

As shown in FIG. 3, a plurality of perforations 421 may be formed in the degradable vinyl film layer 420 to impart breathability to the germination space of the seed 440. This is to ensure stable germination of seed 340 and stable growth of early seedling by maintaining proper temperature and moisture for seed 340 to germinate and grow.

In more detail, the decomposable resin film layer 420 may be formed with a plurality of perforations 421 to have a porosity of 20 to 35%. When the porosity of the decomposable resin film layer 420 is less than 20%, excessive temperature and moisture are present in the germination space of the seed 440, which may cause decay of the seed 440, as well as the seed 440. When germination is long, the initial hair growth can be long and weakly growing, and if it exceeds 35%, the resistance to wind and water damage is low, which may cause breakage of the degradable resin film layer 420 and the moisture content of the germination space may be lowered. , The germination of the seed 440 may be delayed.

In the degradable resin film layer 420 having the plurality of perforations 421, the diameter of the perforations 421 is 5 to 7 mm, and the pitch between the adjacent perforations 421 is 20 to 40. may be mm. When the decomposable resin film layer 420 has a pitch between the diameter of the perforated 421 and the perforated 421 in the above range, the moisture is prevented from evaporating in the soil and the air permeability is improved to prevent the rot of the seed 440. In addition, the seed 440 germinates the temperature and humidity of the germination space appropriately, and has high resistance to wind and water damage to suppress breakage of the degradable resin film layer 420, and the germination space of the seed 440 may be sufficiently secured. have.

The jute mesh layer 430 forms the top layer, that is, the surface layer of the grass mat 400 according to the present invention.

As the jute mesh layer 330 forms the surface layer of the grass mat 400, it is possible to stably fix the soil of the slope, and at the same time to prevent the flying by the wind and water damage during decomposition of the degradable resin film layer 420. It becomes possible.

The jute mesh layer constituting the jute mesh layer 430 is a net having a mesh structure fabricated using the jute thread. The net constituting the jute mesh layer 430 can be used without limitation as long as the net is manufactured using a jute yarn that is commonly used. That is, since the present invention is not limited by the structure or shape of the jute mash layer 430, the structure or shape of the jute mash layer 430 may be variously modified.

5 illustrates the structure of the jute mash layer 430 according to an embodiment of the present invention, FIG. 6 illustrates another shape of the fixing string 435 of FIG. 5, and FIG. 7 is the FIG. 5. Figure 4 shows another shape of the fixing line 436.

5, 6, and 7, the jute mash layer 430 includes a pattern forming line 431 to 433 having a meandering shape in a horizontal direction, and a fragrance portion and an injecting portion of the pattern forming line 431 to 433. And fixed strings 434 to 436 that straighten the side portions corresponding to the central portion in the longitudinal direction. As the pattern forming lines 431 to 433 and the fixing lines 434 to 436 are woven, they may have a mesh structure.

Specifically, since the pattern forming lines 431 to 433 have a meandering shape in the horizontal direction, as illustrated in FIG. 5, the plurality of pattern forming lines 431 to 433 have the same fragrance axis from the upper side to the lower side. Is placed. The fragrance part of the lower pattern forming line 432 is positioned at the central portion of the upper pattern forming line 431 in the longitudinal direction. Therefore, since the two jute yarns overlap, the tensile strength of the jute mash layer 430 may be increased.

As shown in FIG. 5, the fixing line 434 alternates the side portions corresponding to the fragrance portion, the radiating portion, and the central portion in the longitudinal direction of the pattern forming lines 431 to 433, and then goes straight in the horizontal direction. It may be formed to fix the forming lines (431 ~ 433).

However, since the present invention is not limited by the shape of the fixing strings 434 to 436, as shown in FIG. 6, the fixing string 435 is a fragrance portion of the pattern forming strings 431 to 433. The side portion corresponding to the center portion in the longitudinal direction and the rear end may be formed to be bundled by connecting the next unit by going straight in the horizontal direction. That is, the fixing line 435 proceeds to go straight through the central portion in the longitudinal direction of the center pattern forming line 432 among the pattern forming lines 431 to 433 illustrated in FIG. The yarn portion, the fragrance portion of the lowermost pattern forming line 433 is bundled in one unit, go straight in the horizontal direction and connect the next unit.

In addition, as shown in FIG. 7, the fixing cords 435 and 436 are based on the fixing string 435 shown in FIG. 6 so as to be firmly fixed by strengthening the binding force of the jute yarn. Of course, it may be further provided with a fixing line 436 to alternately pass.

As the jute mesh layer 430 is provided on the grass mat 400, since the jute is made of natural material, it is easy to decompose, and its color is suitable for landscaping, thereby being environmentally friendly and generating aesthetics. In addition, it is possible to secure a uniform germination space of the seed 440, increase the tensile strength of the grass mat to increase the soil support. As a result, it is possible to prevent the departure of the soil from the feng shui sea to block the scour or erosion of the soil.

Therefore, since the soil depth of the construction target soil is maintained as it is during the germination and growth of the seed 440, it is possible to implement stability of the ground within a short time, and contribute to forming a firm and dense grass grassland.

The seed 440 is attached to the bottom surface of the straw straw layer 410 to which the vegetation base material is applied.

The seed 440 may be a seed of turf, such as Kentucky Bluegrass, Tall Fescue, Ventgrass, Korean grass, Bermuda grass, Carpetgrass, and the like.

Preferably, the Korean grass turf ( Zoysia) has a high distribution rate among native grasses in Korea in order to reduce ecology and aesthetics and to reduce construction costs. japonica Steud. ). The Korean grass has disadvantages of slow germination speed and low greening efficiency, but as described above, the grass mat 400 according to the present invention promotes early germination of the Korean grassgrass seed 440 so as to implement excellent greening efficiency. do.

The seed 440 may be attached using a water-soluble adhesive as described above in the vegetation base material, and it is preferable to use an aqueous starch oxide solution for improving the environment and germination, but for the attachment of the seed 440. The present invention is not limited by the adhesive.

The seed 440 may be mixed with the water-soluble adhesive and applied to the bottom surface of the rice straw fabric layer 410.

As described above, the grass mat 400 for slope recording according to the present invention is integrally formed, and thus easy to transport and install, and thus excellent construction property. The grass mat 400 formed integrally has been described above based on the straw straw fabric layer 410, the decomposable resin film layer 420, and the jute mesh layer 430 bonded to each other by an adhesive as described above. Needless to say, it may be combined by needle punching according to the embodiment of the implementer and production process. That is, jute rope fibers (not shown) are arranged on the top of the jute mesh layer 430 at a predetermined interval apart from each other horizontally and vertically to allow the jute rope fibers to be bound to the bottom straw straw layer by needle punching. This is because when using the adhesive, the germination space can be occluded by the adhesive when the seeds germinate, whereas in the case of binding by needle punching, this disadvantage can be avoided and it is more environmentally friendly. There is this. The jute rope fiber refers to a yarn bundle made of a thin thread by splitting jute yarn in layers, and has an advantage of excellent durability and binding force due to needle punching.

On the other hand, in the case of binding by needle punching, water-soluble adhesive for attaching seeds to only the bottom of the straw straw layer may be used, and the remaining layers are bound by the top jute rope fiber, and the seed is attached after the needle punching process. It is preferable to make it.

During the greening work, the lower surface of the straw straw fabric layer 310 to which the seed 440 is attached from the grass mat 400 is directed toward the slope to be constructed, and then sloped using a binding support such as an anchor pin or an iron plate pack. Will be attached to the

Then, since the shape retaining strength is enhanced by the straw straw layer 410 and the jute mesh layer 430, it is possible to secure the stability of the slope until the grass paper is formed.

In addition, not only the seed 440 of the grass attached to the lower surface of the straw straw layer 410 for greening can be effectively buried in the construction target slope, but also by the excellent water retention and bobbin power of the grass mat 400. Promotes early germination of 440 to increase the efficiency of rooting on the slope to be constructed, thereby smoothly rooting.

In addition, the moisturizing power, the auxiliary power and the soil improvement power of the material constituting the grass mat 400 shortens the germination period of the seed 440, it is possible to continuously supply nutrients to the soil, the composition of excellent grass grass Efficiency, that is, recording efficiency can be obtained.

FIG. 8 shows a comparison picture of a conventional grass mat (left and right) using Korean grass and a grass mat (middle) manufactured according to the present invention on a slope after two months. In the case of the conventional grass mat, the seed does not come in direct contact with the soil, and the moisture retention and heat retention are low, whereas the growth state is not good, when the grass mat according to the present invention is constructed, the growth state is very excellent. .

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible.
