Description

An artificial soil composition for protection of soil sliding}

1 is a block diagram showing a preferred embodiment of the present invention.

Figure 2a ~ 2c is a photograph showing the vegetation state of non-repair, whipping love glass after 45 days after construction.

The present invention relates to a green soil composition, and more particularly, the present invention relates to a wet artificial soil composition that can be used to restore the environment of the cut area, hilly land filling area in which artificial vegetation is required.

In the cut or hilly areas that occur during large-scale civil works, soil sedimentation occurs due to summer rainfall or winter snowfall, and the natural forest landscape is destroyed by heavy rain or strong winds, and in some cases large road traffic accidents occur. Artificial greening is essential for the preservation of the natural environment.

Until now, a number of artificial soil compositions and related technologies for natural environment restoration have been disclosed in Korea and Europe.

For example, Korean Patent Nos. 10930, 11616, 413776, and the like.

On the other hand, artificial greening method is also known as giant covering, nylon net using method, comat method, seed spray method, etc.As the greening method using artificial soil composition, dry method using green water and artificial soil of artificial soil material for greening Wet methods have been developed for mixing water with materials. Korean Patent Nos. 10930 and 11616.

However, the artificial soil compositions are artificial soil composition due to the separation and cracking of the existing soil due to the lack of adsorptive power of artificial soil in sliding or dry weather conditions due to the soil composition flows down by the rainfall during spraying and construction. Lack of this moisturizing power often resulted in poor or dead vegetation.

In this case, civil defects frequently occur due to construction defects, and friction between operators and builders has emerged.

The present invention has been made in view of the disadvantages of the conventionally known artificial soil composition is to provide a wet green soil composition.

In particular, it is an object of the present invention to provide a new wet green soil that significantly increases the water holding capacity, increases the bobbin power and breathability, and significantly maximizes the water holding power and sticking power after construction greening.

The above object of the present invention is 20 to 25% by weight of fine dust, 15 to 20% by weight of food sludge powder, 15 to 20% by weight of cow manure premature powder, 10 to 15% by weight of bark and side leaf soil, 10 to 15% by weight of peat, lead Material 5-10 wt%, Lightweight soil 5-10 wt%, Bacillus subtilis sp. In preparing an artificial soil composition consisting of 1 to 5% by weight of a strain and a Gibberellin 1: 1 mixture of plant growth control nutrients, the plant growth control nutrients are sprayed with water to provide wet green soil and its physicochemical properties. Achieved by examining.

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

The fine soil used in the present invention is obtained by crushing the ground granules by collecting the weathered granite together with the soil and increasing the permeability of the soil. It is mixed as a main material to improve the air permeability, the composition ratio is preferably 20 to 25% by weight, and constitutes 1/5 to 1/4 of the composition is the biggest feature of the present invention.

The secondary main material constituting the composition of the present invention is mainly for supplying Carbon Source, 15-20% by weight of food sludge powder and mainly Nitrogen Source, 15-20% by weight of cow manure accessory powder.

Food sludge is completely dried and collected from restaurants, schools, and factories. It mainly supplies carbon sources to microorganisms and vegetation in the soil, increases moisturizing and preserving power in the soil, and improves adhesion to the soil after construction. And prevent the action of inhibiting sliding phenomenon.

Udon manure powder is mainly mixed for the purpose of supplying Nitrogen Source and trace elements to the vegetation, and it should be fully matured after the wet application, especially without the occurrence of CO, NO ₂ and N ₂ .

The tertiary materials constituting the wet green soil of the present invention are 10 to 15% by weight of bark and subleaf soil, 10 to 15% by weight of peat, and 5 to 10% by weight of combustion ash.

Bark is a wood processing by-product, such as pine bark, pine bark, oak bark, ash bark, paulownia bark, and finely pulverized them. In addition, the bark soils are oak leaves, oak leaves, acacia leaves, Premature deposits of hardwood leaves, such as these, are preferable.

Peat is a type of coal that has undergone carbonization. It contains a large amount of natural fertilizer and is mixed with not only three elements such as N, P and K, but also as a source of trace elements. As the remnant of combustion, they act to improve the physicochemical properties of the soil such as moisturizing power, fertility, water retention, and breathability of the green soil vegetation, and in particular, in the present invention, C.E.C.

As the remaining material constituting the composition of the present invention, lightweight soil is most preferably a zeolite as a secondary mineral suitable for supplying moisture to the artificial soil composition itself of the present invention and at the same time maintaining the activity of microorganisms.

Zeolite as a lightweight soil is formulated with Bacillus subtilis sp, which is an effective microorganism for the maturation of vegetable compost materials, and a plant growth regulator for improving early vegetation during mixing of these microorganisms, as well as warm or cold grass seeds and vegetation seeds. Water growth control It is effective in maintaining the function of attaching nutrients and increasing the C, E and C effects.

Soil physical variables such as 40% of effective moisture content, 7.7% of soil porosity, and 30.4% of cation substitution capacity (CEC) were high, indicating that the early and late growth of vegetation was excellent.

<Example of Construction>

Using the present invention green soil composition having the preferred physicochemical properties as described above test results in the Jungbu Expressway Construction Zone No. 0 surface protection construction area was as shown in Figures 2a-2c.

The test construction method stops the surface uniformly and then installs the wire mesh uniformly to the surface irregularities and installs it firmly using a fixed jig, and then the wet green soil composition of the present invention is a non-repair, weeping love grass (weping love grass) Seeds were mixed with plant growth control nutrients, respectively, and then sprayed with water at the level of water for packaging to the green soil composition, and left for about 1 hour to allow the seeds to completely adhere to the soil composition of the present invention.

Figure 2a ~ 2c is a photograph showing the vegetation state of each when 45 days have passed after construction.

As shown in FIGS. 2a to 2c, the results of the construction using the ripened greenery composition according to the present invention showed that the vegetation rate, the sliding rate, and the appearance of grasses and vegetation seeds were very excellent, so that the natural collapse or sliding of the incision surface soil during the summer heavy rains. The phenomenon could be suppressed.

As described in detail above, the wetted green soil composition of the present invention has significantly higher physicochemical properties than organically known soil compositions because of its organic content, effective phosphoric acid content, kali content, total nitrogen content and effective water content, soil porosity, and cation substitution capacity. As a result, during the large scale wet rust of the surface, the vegetation rate, the growth rate, and the aesthetics of the seeds such as grass and vegetation are remarkably improved, and it has an excellent effect of suppressing soil erosion, natural collapse and sliding phenomenon. It is a very useful invention for the large-scale greenery industry.
