[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope greening method.

[0002]

2. Description of the Related Art
When constructing a slope, planting trees is indispensable from the viewpoint of protection of the slope, conservation and restoration of the natural environment, and harmony with the surrounding landscape.

However, in the actual slope revegetation method, it is difficult to obtain a uniform vegetation state of a plant due to scattered rough soil conditions because the slope physical properties of the slope are greatly affected. .

[0004] In addition, in the slope construction work, a large amount of root removal material is generated during the construction, and since this root removal material has recently been revised in the "Waste and Cleansing Law", it has been conventionally used on site. In principle, open burning is prohibited, and this large amount of root removal material must be disposed of as waste at a large disposal cost.

[0005] However, facilities for accepting a large amount of root extraction material as waste have not yet been developed, and are currently regarded as a major social problem, and various studies have been made on methods of treating the root extraction material.

[0006] In order to solve the above-mentioned problems, the applicant of the present invention has adopted the concept of recycling root extraction materials on the slope formed by the development work to remove the root extraction materials generated by the construction work. We studied a slope revegetation method that can form plants on the slope in a uniform vegetation state by recycling and using it on the slope.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and it is an object of the present invention to recycle a root extraction material generated by a construction work for use on a slope formed by the construction work. Accordingly, the present invention provides a slope revegetation method that enables plants to be restored on a vegetation in a uniform vegetation state on all slopes in accordance with the surrounding vegetation environment and ecosystem.

[0008]

The gist of the present invention will be described with reference to the accompanying drawings.

[0009] The root removal material generated during the slope construction work is formed into chips, and the chipped chip material is used as a root material of several cm or more.
The large chip material is separated into a small chip material having a size of several cm or less including rhizosphere soil and a large chip material to which no rhizosphere soil is attached, and the large chip material is subjected to a carbonization treatment of drying and then burning. A small chip material containing the rhizosphere soil is formed on the slope base layer 1 formed by the slope construction work to a predetermined thickness as a carbonized layer 2, and is suitable for plant growth on the carbonized layer 2. The present invention relates to a slope revegetation method characterized in that it is mixed with a plant growth base material formed on a soil that has been soiled to form a plant growth base layer 3 with a predetermined thickness. Further, in the slope greening method according to claim 1, a small chip material containing rhizosphere soil is mixed with a plant growth base material containing fertilizer or the like to form a plant growth base layer 3. It relates to the greening method.

[0010] Further, in the slope greening method according to any one of claims 1 and 2, the carbonized layer 2 is formed by mixing a pH adjusting agent with the carbonized carbonized material. It is related to.

Further, in the slope greening method according to any one of claims 1 to 3, the carbonized carbonized material is mixed with the plant growth base layer 3 to form the plant growth base layer 3. It relates to the slope greening method.

[0012]

The following is the reason why the root removal material generated during the slope construction work is converted into chips, and the chipped chips are separated into large chips and small chips containing rhizosphere soil. by.

When a large amount of impurities such as soil adhere to the chip material, a large amount of clinker is formed during the carbonization treatment. However, except for the small chip material to which the rhizosphere soil and the like are adhered.
If only the large chip material to which the rhizosphere soil does not adhere is carbonized, the amount of clinker generated can be reduced accordingly. In addition, if soil or the like is attached to the chip material, it takes a long time for the carbonization process, the fuel cost increases, and further,
The resulting carbides are also inferior, but the sorted roots
If only the large chip material to which the zone soil is not attached is carbonized, the carbonization time can be reduced, the fuel cost can be reduced, and good quality carbide can be generated.

[0014] Furthermore, since the carbonization treatment in which the large chip material is dried and then burnt is performed, by drying the root material having a high moisture content, the carbonization time can be shortened.
The fuel cost can be reduced, and the fuel cost for drying the large chip material can be reduced by utilizing the heat generated when carbonizing the drying of the large chip material.

Further, since the carbonized carbonized material is formed as a carbonized layer 2 on the sloped base layer 1 formed by the slope construction work to a predetermined thickness, the sloped base layer 1 is a factor inhibiting plant growth. Can prevent the growth inhibiting factor from affecting the plant growth base layer 3 in the upper part of the slope by the adsorption action of the carbonized layer 2.

Further, a small chip material containing rhizosphere soil on the carbonized layer 2 is mixed with a plant growth base material formed on soil suitable for plant growth to form a plant growth base layer 3 with a predetermined thickness. Therefore, it is possible to mix the rhizosphere microorganisms and plant nutrients useful for the growth of plants living in the rhizosphere soil into the plant growth base layer 3. Seeds of plants that are naturally growing on the slopes are also mixed in the rhizosphere soil. By mixing such rhizosphere soil into the plant growth base layer 3, the surrounding slopes Planting that is in harmony with the vegetation environment and ecosystem can be restored in a uniform vegetation state.

As described above, by using the root removal material generated during the slope preparation work for the slope preparation, it is possible to reuse the root removal material that had to be conventionally treated as waste. By reusing root-extracted materials that had previously been disposed of at high disposal costs as waste, as an effective resource, it was possible to reduce the costs of excavating root-extracted materials and to reduce the amount of soil used to form slopes. Cost can be reduced, and overall cost can be significantly reduced.

Further, since the small chip material containing the rhizosphere soil is mixed with the plant growth base material containing the fertilizer and the like to form the plant growth base layer 3, the surrounding vegetation environment and the ecosystem Plants that are in harmony with green can be revegetated in a very good and uniform vegetation state.

Further, since the carbonized layer 2 is formed by mixing the pH-adjusting agent with the carbonized carbonized material, for example, even if the slope base layer 1 is a strongly acidic soil, the carbonized layer 2 is not only adsorbed but also absorbed. Due to the neutralizing action of the pH adjuster, the slope base layer 1
Can be prevented from affecting the plant growth base layer 3 and a uniform plant vegetation state can be reliably obtained on the plant growth base layer 3.

In addition, since carbides are mixed into the plant growth base layer 3, the microorganisms inhabiting the plant growth base layer 3 use the carbides as starting points for the growth of the microorganisms.
The activity of microorganisms is activated to promote the decomposition of organic matter,
An environment favorable for plant growth can be formed in the soil of the plant growth base layer 3. Further, it is possible to prevent the fertilizer component from flowing out from the plant growth base layer 3.

Further, since the carbonized carbon is formed to a predetermined thickness as the carbonized layer 2 on the slope base layer 1 formed by the slope construction work, there is a factor inhibiting plant growth in the slope base layer 1. However, the growth inhibition factor can be prevented from affecting the plant growth base layer 3 in the upper part of the slope by the adsorption action of the carbonized layer 2, and the small chip containing the rhizosphere soil on the carbonized layer 2 can be prevented. The wood is mixed with a plant growth base material formed on soil suitable for plant growth and formed into a predetermined layer thickness as a plant growth base layer 3, so that rhizosphere microorganisms useful for the growth of plants living in the rhizosphere soil And nutrients of the plant can be mixed into the plant growth base layer 3. At this time, the seeds of the plants, which are naturally growing on the slope before the slope is being constructed, are also added to the rhizosphere soil.

By reusing root-extracted materials that had previously been disposed of at high disposal costs as waste, as an effective resource, it was possible to reduce the costs of excavating root-extracted materials and to reduce the amount of soil used to form slopes. Cost can be reduced, and overall cost can be significantly reduced.

Further, since the small chip material containing the rhizosphere soil is mixed with the plant growth base material containing fertilizer and the like to form the plant growth base layer 3, the surrounding vegetation environment and the ecosystem are formed on the slope formed. Plants that are in harmony with green can be revegetated in a very good and uniform vegetation state.
