Description

Soil addition composition for greening slope land}

The present invention relates to a landscaping composition for sloping greenery, and more specifically, to prevent acidification of vegetation ground, and sloping paper mixed with natural fibers (short fibers) to prevent erosion and loss due to plastic deformation and weathering of surface parts. It relates to a green soil composition for greening.

In general, if the inclined surface of the rock or the upper surface of the concrete is left unattractive, it is unsatisfactory, and the stability is also a problem in the sea ice or rainy season. Therefore, there is a need for a greening method that protects the human living environment by stably protecting it, and facilitating the water supply necessary for the rooting of the green vegetation even during the dry season.

Currently, inclined green vegetation methods that are widely distributed in Korea are planted only by seeding, incorporating seeds, fertilizers and soil into artificial vegetation mats and laying them on slopes, and then laying wire mesh or nets on slopes. It is divided into a method of forming artificial vegetation ground by forming artificial turf to a predetermined thickness on the upper side.

Looking at these methods in more detail, the method of planting with only seed is a vegetation method for loose soil ground where the slope is very gentle and the surface of the slope can function as a vegetation ground, and the method using artificial vegetation mat Is a vegetation method for relatively hard soils and weathered residual soil layers where the sloped soil is a vegetative ground, which is a vegetative ground, and is a method of vegetation of slopes of less than 20 degrees of soil hardness and about 45 ° of slope. The method of forming artificial vegetation ground by laying a wire mesh or net type and covering artificial soil with a predetermined thickness on the upper part (artificial vegetation spraying vegetation hole) is a ground whose slope is vegetative ground, which is impossible to function. Hardness of inclined surface by vegetation method for weathered residue soil, weathered rock layer, blasted rock layer which is hard sand (more than 20 hardness) The vegetation is how the steep slope up to a maximum of approximately 75 °.

The net is formed, and the wire mesh is installed when the slope is long and the slope is steep, and there is a risk of falling and partial collapse. Subsequently, a method of attaching vegetation soil, which is a main material for ensuring the survival and growth of a plant, to a completed surface is disclosed. At this time, the vegetation soil is an artificial oriented material that provides the space to keep the roots and retain the moisture, minerals, and organic matters necessary for the growth of the plant, and mixes the soil improver, organic fertilizer, adhesive clay, and curing agent with special humus The special foaming agent is added to prepare and use the special clay which has good repair and maintenance, and which can form a single structure.

A seed trace method or a soil stabilization method is disclosed.

However, these methods currently have relatively good vegetation effects of grass, but have problems in the future due to acidification of vegetation ground due to acid rain, and the method of attaching artificial soil only to crack formation when repeated drying and wetting due to material separation. Partial dropout occurs frequently, and it is difficult to secure the adhesion between the PVC coated wire mesh and the ground, and the method of attaching the artificial soil into the artificial soil by mixing it with the continuous artificial fiber reinforcement effect Although the effect of reducing the cracking width can be expected, material separation can be prevented relatively between the surface part and the PVC coated wire mesh based on the PVC coated wire mesh, but continuous artificial fiber is mixed between artificial coated soil and the artificial soil between the PVC coated wire mesh and the ground. Due to the lack of construction technology, the common problem with these methods is that acidification of vegetation soil Measures, PVC coating material while preventing the segregation of the artificial gaekto is mounted between the wire mesh and wonjiban, there is a need for a method that can be expected to ensure the workability, such as adhesion, moisture-retaining.

Therefore, in the present invention, the artificial straw (green soil and green soil) is cut into 3 to 5 cm in size of straw made of natural fiber (short fiber) and mixed with 1 to 5 or so of the artificial clay weight and the thickness of the PVC coated wire mesh As it is about 5-6cm, artificial soil mixed with these natural short fibers passes freely through the PVC coated wire mesh, so it has good adhesion between the base sheets, prevents moisture retention (single structure) and material separation, and uses an acid regulator. It has thus been found that the phenomenon of the acidification of vegetation ground can be minimized, and the present invention has been completed based on this.

Therefore, an object of the present invention is to prevent acidification of vegetation ground and good adhesion between the PVC coated wire mesh and the ground, and the artificial soil around natural short fibers exhibits a single structure to form moisturizing and material separation phenomena to prevent the phenomenon of material separation. It is to provide a clay composition for.

The composition of the present invention for achieving the above object is one from the group consisting of 30 to 50 weight of organic flounder soil having a water content of 50 to 80, 40 to 60 weight of earth and sand having a water content of 5 to 15, straw, barley straw and straw or More than 1.0 to 5.0 weights of natural short fibers, 5 to 12 weights of water, 0.001 to 0.1 weights of sodium alginate, and 0.001 to 0.1 weights of acidic regulators.

1 is a schematic view showing a cross-section of the composition according to the invention on a slope.

Looking at the present invention in more detail as follows.

In general, the cut slopes are mostly weathered residues, weathered rocks, and blasted rocks, and the soil hardness is more than 20, which makes plant rooting impossible, and because the plant is very bad vegetation ground without nutrients for plant growth. It is necessary to form a vegetative ground that can grow, and cover the artificial soil to green the slopes and vegetation, and use the mixed grassland seeds of exotic grassland and legume shrub bushes of native vegetation.

The present invention relates to the artificial clay composition, wherein the composition is 30 to 50 weight of organic flounder soil, 40 to 60 weight of earth and sand, 1.0 to 5.0 weight of natural short fiber, 5 to 12 weight of water, 0.001 to 0.1 weight of sodium alginate, and acidic And 0.001 to 0.1 weight of a regulator.

At present, artificial turf produced domestically lacks the main resources of the peat (organic material, such as plants, trees, etc. deposited) which is the most important component of the composition, and the sludge of sewage treatment plant to cope with these peat contents The use of cakes is currently being implemented, but this poses a problem of causing environmental pollution. Therefore, in the present invention, the organic flounder soil is used in an amount of about 30 to 50 weight. At this time, if it is less than 30 weight, nitrogen and carbon components are small, so germination and growth rate is low. There exists a tendency for regeneration germination rate to fall. The organic flotation soil is preferably peat, peat moss, or organic compost, but is not limited thereto. The organic component may include all of the decayed deposits. It is preferable that the organic flounder has a water content of about 50 to 80 in terms of ease of transportation, handling and storage of materials, and ensuring the formulation workability.

Soil used in the present invention is a mixed soil mixed with coarse sand and 1: 1 to 3 of the local soil, and the water content is about 5 to 15. The most efficient workability is secured when the artificial soil is mixed. In the case of installation, the material separation phenomenon is the least preferable. The use amount is preferably 40 to 60 weight. If it is less than 40 weight, the organic subleaf soil content is relatively increased, and the growth rate is too fast, so that the regeneration germination rate is reduced by the dense phenomenon of grass. It is less than nitrogen and carbon content tends to be low germination and growth rate.

The natural short fibers are cut into 3 to 5 cm in size of stems (hereinafter referred to as "straw") of fossil plants such as straw, barley straw and straw, and are used by mixing about 1.0 to 5 weight with respect to artificial soil. At this time, if the amount is less than 1.0 weight, the material separation phenomenon often occurs during construction, and when the amount exceeds 5 weight, excessive porosity tends to occur in the artificial soil. The reason why the straw is cut into 3 to 5 cm is used as the distance between the PVC coated wire meshes formed between the artificial lands as shown in FIG. 1 is about 5 to 6 cm. This is because the artificial soils formed around the natural short fibers are freely passed through the PVC coated wire mesh, and the artificial turf formed around the natural short fibers exhibits a single structure to improve moisture retention and prevent material separation. In addition, since artificial soils mixed with these finely-cut straws exhibit the effect of reinforcement soils, the probability of cracking during drying is less than that of conventional artificial soils, and the dropping prevention is prevented, and as an organic fertilizer. It can improve the growth and development conditions of plants. In addition, it is possible to solve some of the problems caused by the environmental pollution caused by the sludge cake of the sewage treatment plant using a straw made of natural fiber.

In the present invention, it is preferable to use the acidic regulator, the erosion inhibitor, and the fertilizer by diluting and dissolving it in water. If this is not the case, a material separation phenomenon occurs. At this time, the amount of water used is about 5 to 10% by weight, and clean water having a pH of about 6 to 7 is preferred as natural water instead of tap water. When the amount of water used is less than 5 weights, a partial material separation phenomenon occurs, and when the amount of water exceeds 10 weights, the material separation phenomenon is prevented, but the water content of the artificial soil is high, so that the transport, handling and construction management are difficult. In addition, sodium alginate is used as an erosion inhibitor, and its amount is preferably 0.001 to 0.1 weight. At this time, if the content is less than 0.001 weight, the adhesive force of the artificial soil is lowered, so that the phenomenon of easily falling off during drying occurs, and if it exceeds 0.1 weight, the artificial soil is too hard to tend to suppress the initial germination effect of the plant. In addition, since the soil has recently been acidified due to acid rain, it is essential to add an acid regulator (chemical fertilizer) that can neutralize the pH of the soil. Examples of such acidic regulators include lime phosphate and fertilizers, and the amount of the acid regulator is preferably 0.001 to 0.1 weight.

On the other hand, the vegetation method of spraying artificial turf on the surface of the slope is currently used domestically and can use the method. The mounting thickness is 10 cm, but the thickness can be adjusted within the range of 5 to 15 cm depending on the characteristics of the ground. The construction cross section for this is as shown in FIG. Referring to Figure 1, after the nail is installed on the slope according to the nail (nail) method, the PVC coated wire mesh or geogrid (Geo Grid) net (for example, PP net or PE net) is installed slightly spaced apart from the slope , Spread the composition of the present invention on the slope.

In the present invention, the seed may be sown in the artificial soil in order to prevent greening and erosion of the soil. As the seeds, meadow type seeds are divided into perennial and perennial, and meadow type seeds have very short initial germination but short lifespan. Varieties) have a low initial germination rate and a long lifespan because they are similar to the germination rate due to vegetation transition, so the two seeds are mixed and used. The standard blending content of the seeds is considered to be 60% of the grass type seeds and 40 seeds of the shrubbery species. The grassy seeds of the genus (cold) are 50 perennial and 50 perennial. Seeds are used by mixing two seeds in a ratio of 1: 1. As the growth and development of seeds may be slightly different depending on the soil, construct artificial soil for this, and consider the time of germination and growth growth. It is preferable to record.

Hereinafter, the present invention will be described in more detail with reference to Examples, but the scope of the present invention is not limited to the following Examples.

Examples 1 and 2

The artificial turf of the surface part is blended according to the standard shown in Table 1 below, and during construction, material loss occurs due to the effect of compression and dropping due to spraying, so the material premium is calculated as 25 to construct as shown in FIG. 1. It was. After construction, grassland seeds 60, shrub bushes (40 kinds) seeds are blended to about 40, grassland seeds (in the cold district) 50% perennial, perennial 50% perennial shrubs (Saris) seeds are 2 seeds. It mixed at the ratio of 1: 1.

When the vegetation cover by artificial soil is completed, most of the grassland seeds are cold-type, and they are caused by intense sunlight, and the phenomenon of death or death during early germination is covered, so it is necessary to cover the shade shading net immediately after construction to suppress the rapid moisture evaporation and sunlight. The initial growth and growth conditions were created by blocking the shade.

As a result, there is no appearance of cracks that occur like turtles during drying when the influence of natural short fibers is remarkable, and only microcracking behavior with natural short fibers is shown, and the reinforcing effect by natural short fibers is very good. I could confirm that. In addition, the characteristics of early germination show that most seeds (seeds) are germinated in these microcracks, so that natural short fibers provide a single structure of vegetation ground necessary for plant growth, and artificial inside the PVC coating network. The soil was also distributed and formed evenly.

As described above, the artificial clay according to the present invention exhibits a reinforcement soil effect, which is less prone to crack occurrence than the conventional artificial soil mounting method, prevents falling off, and prevents acidification of vegetation soil and organic fertilizer. Its effect was to improve the growth and development conditions of plants. In addition, the use of straw, which is a natural fiber, was able to solve some of the problems of causing environmental pollution by the sludge cake of the sewage treatment plant.
