It is about.

In general, the slope vegetation method is a general method of protection of slopes, and vegetation grows on slopes and slopes to prevent erosion of slopes and to fix surface soil by root system. Under the condition that the vegetation hole is not suitable for the conservation, the thick layer base material spraying method or the seed seed spraying method is used.

The method of flushing with the seed means to artificially create a growth base of the vegetation by spraying the seed together with artificial soil. Most soil slopes provide enough vegetation-based soil for plants to grow, but after cutting, there is a limit to the growth of plants because of the lack of soil that can supply water and nutrients for seeds to grow. .

In particular, about 67% of the topographical geological conditions in Korea are mountainous topography, and because of the shallow rock formations, the environment is difficult to grow. Therefore, it is necessary to develop soil improvers for the growth of the plant. .

A slope protection construction method using soil stabilization and improving agent is provided, and Korean Laid-Open Patent Publication No. 10-2015-0061761 (2015.06.05.) Is an artificial ground that recycles waste resources such as coffee grounds and sawdust. Artificial soil composition for greening and improved soil containing coffee grounds as a manufacturing method thereof; and 0.1 to 3% by weight of solidifying agent based on the weight of the improved soil; It is provided with an artificial soil composition for greening the artificial ground is formed by mixing;

Looking at the prior art, there is still a problem of environmental pollution since the use of conventional industrial by-products, and when the improver is manufactured using materials such as simple coffee grounds, the durability becomes weak, and the efficiency of slope greening is difficult to verify. have.

The name of the present invention is "a soil improver composition to allow vegetation for slope greening and slope protection construction method using the same" to describe the specific details so that a person skilled in the art can easily know, a separate description that can be sufficiently inferred is omitted, necessary Examples and drawings are described. In addition, terms defined in the present specification and claims are not limited to interpretation and may vary according to the intention or custom of the operator and should be interpreted as meanings and concepts corresponding to the technical spirit of the present invention.

In one aspect of the invention,

The vegetation modifier composition is

A main material consisting of local soil, side leaf soil, herbal remnants and textile materials;

Additives comprising a binder, a hardener, a powder thickener, a super absorbent polymer (SAP) and a moisturizer; And

It comprises a weak alkaline water; pH concentration is 7.2 ~ 7.6.

The main material is 82 to 84% by weight, the additive is composed of 7 to 10% by weight and weak alkaline water 7 to 10% by weight.

The host material is 69-75% by weight of local soil, 9-16% by weight of foliar soil, 7-13% by weight of medicinal herb residue fermented with Effective Micro-organisms (EM) fermentation solution, and at least one selected from coconut shell, hemp and rice straw fiber materials. It consists of 1 to 5% by weight of the fiber material.

The foliar soil is prepared by using a general natural foliar soil mixed with more bark compost to improve the water holding capacity, the bobbin power to enhance the adaptability to the slope environment, can improve the pH, nutrient retention and buffering capacity of the planting soil.

Sik herb residue is fermented with yeast, lactic acid bacteria, photosynthetic bacteria and fermentation of EM (Effective Micro-organisms) cultured beneficial microorganisms are helpful for plant germination.

The additive consists of 39 to 51% by weight of the binder, 29 to 41% by weight of the curing agent, 3 to 7% by weight of the powder thickener, 1 to 3% by weight of the super absorbent polymer, and 7 to 13% by weight of the moisturizing agent.

The binder is composed of 33 to 37% by weight of micro cement, 8 to 12% by weight of Arwin-based cement, and 53 to 57% by weight of hemihydrate gypsum.

The micro cement is commercially available and is composed of inorganic materials as in Portland cement, and is a pollution-free injection material without toxicity and odor. In addition, the ultrafine particles have been adjusted to control the initial hydration rate, the particle size is less than the general cement, and the penetration between the particles and the fine crack is high.

The Irwin-based cement is manufactured by mixing and burning the municipal waste incinerator, water purification sludge, gypsum, fluorite and silicon carbide.

The gypsum hemihydrate is a calcined gypsum, which performs its own role as a binder, and does not require an inorganic composite binder, and because of its high specific surface area, it is easy to control the coating amount of the chemical group.

The hardener is an expandable hardener, the powder thickener is a montmorillonite-based bentonite powder, and the moisturizer is a polycarboxylic acid-based polymer liquid plasticizer.

The expandable curing agent is gypsum, a mineral made of calcium sulfate hydrate, and bentonite reacts with water due to its physical properties, expands about 13 to 16 times larger than its original volume, absorbs water up to 5 times its weight, and forms soil and mixed layers. The water permeability coefficient of city water is small, which can prevent groundwater contamination.

The super absorbent polymer (SAP) may be generally used, but it is preferable to increase the binding strength with the binder by using a cellulose-based absorber and a bentonite-based polymer compound.

In addition, since the binder and the curing agent exhibit strong alkalinity, it is adjusted to a pH suitable for growth of vegetation using weak alkaline water.

Example  : Binder  combination

Among the additives of the present invention, the binder, micro cement, Irwin-based cement, and hemihydrate gypsum were cured by blending the respective weights as shown in Table 1 below.

Micro cement Irwin cement Half gypsum One 55 10 35 2 35 10 55 3 35 50 15 4 25 40 35

Test Example  : Binder  Compressive strength test

In the above embodiment, the compressive strength test of the binder of 1 to 4 prepared for each mixing ratio was performed. 30 days after curing at the compounding ratio, the compressive strength was measured, 1 is 43 compressive strength (MPa), 2 is 49 compressive strength (MPa), 3 is 41 compressive strength (MPa), 4 is 34 compressive strength The compressive strength of 2 was found to be high as (MPa).

Therefore, the combination of the binder is prepared in the same compounding ratio as in Example 2 to prevent the accident of flowing down or collapse by increasing the strength of the surface layer when mixing the soil surface of the slope and the soil improver of the present invention.

In a further aspect,

The superabsorbent polymer may be used in place of a super absorbent polymer composed of bio cellulose and carrageenan. The preparation of the super absorbent polymer composed of bio cellulose and carrageenan is biocellulose and red algae forming a powder form of microfibrous structure produced by bacteria. After collecting and drying the edible seaweed, the pulverized powder was stirred with heated purified water, dissolved with potassium chloride and cooled at room temperature to produce a gel state. The pulverized powder was injected with ethanol and pulverized. It is prepared by dehydration and drying.

The amount of potassium chloride (KCl) is preferably 1: 0.004 to 0.006 by weight of red algae powder and potassium chloride prepared in the preparation step.

Therefore, it is possible to prevent soil pollution by adsorbing impurities from environmental pollution and binder using environmentally friendly superabsorbent resin.
