Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for collecting a vegetation material used for greening a slope or a bare ground, and a greening material based on the collected vegetation material.

[0002]

2. Description of the Related Art In recent years, when greening slopes or bare land, surface soil (including soil containing humus) that contains deciduous leaves on the surface layer of the Yamano area adjacent to the construction site of the greenery has been collected in recent years. The greening method that uses the falling seeds of is being adopted.

That is, surface soil containing fallen seeds of local vegetation is sampled, and this is used as vegetation soil. A soil improving material is mixed with this to make a greening material, which is sprayed on slopes as a soil material. Alternatively, they are packed in sandbags and used as vegetation sandbags to create greenery that does not confuse the flora of the surrounding area.

When collecting the surface soil to be used as this vegetation soil,
Conventionally, heavy machinery such as backhoe is used to excavate the surface soil in Yamano, and the excavated soil is loaded onto the carrier bed and transported to the collection site. Large gravel, roots, branches, etc. are removed, and this is used as vegetation soil and mixed with soil improvement materials and stocked as greening material.

If necessary, the greening material is transported to the construction site of the greening work and used as a soil material for the slopes, or it is packed in sandbags and used as vegetation sandbags.

[0006]

However, in order to load heavy equipment such as a backhoe, road construction requiring enormous construction cost is required in the surface soil sampling area, or it is not necessary to do road construction. However, there was a problem in that it was necessary to cut the standing trees that hinder the movement of heavy equipment, and destroy the vegetation in the surface soil sampling area.

[0007] Further, what is suitable for use in revegetation is the surface soil or the surface soil containing the defoliation and the falling seeds contained therein. However, the thickness of the surface soil that can be used as vegetation soil is usually However, even though it is very thin, such as several cm to ten and several cm, the heavy soil machine excavates the surface soil deeply, so there is a problem in that the collection area of the surface soil is devastated.

Furthermore, in addition to the problem of disposing of the selectively removed gravel, the extraction of excavated soil with a backhoe or the like becomes bulky because it contains more earth and sand than is necessary, and there is a problem in terms of stock. In addition, since it is a heavy item,
For example, there is a problem in that the workability is extremely poor when the greening material is packed in a sandbag or handled as a vegetation sandbag.

The present invention has been made in view of such circumstances, and its purpose is to prevent the existing vegetation from being adversely affected and to prevent the inclusion of earth and sand and large gravel as much as possible. The present invention is to provide a method for collecting mainly falling leaves or surface soil containing falling leaves and falling seeds, and a greening material based on the vegetation material collected by the method.

[0010]

[Means for Solving the Problems] That is, the method for collecting vegetation material according to the present invention is a method for collecting vegetation material used for greening a slope or bare land, and It is characterized in that high-pressure air is blown to the surface soil containing it to dissolve it, and the leaf leaves or surface soil thus dissolved and the fallen seeds contained therein are used as vegetation material, and this is sucked and collected by vacuum (( Claim 1).

The above-mentioned surface soil containing deciduous leaves generally means
It refers to the soil referred to as the A _{00 to} B layers of the soil profile formed in the mountains and forests, and unravels the surface soil from the undecomposed deciduous layer to the layer in which this deciduous layer decomposes and accumulates nutrients. Then, the soil mixed by this unraveling is sucked and collected by vacuum, and most preferably, the A ₀ -A ₂ layer in which the defoliation starts to decompose mainly.

[0012] to the solution of the surface soil, including the surface deciduous or deciduous
In is an effective blowing pressure d A, with the blowing of the high-pressure air, is preferred in that it does not damage the existing tree roots.

[0013] It is preferable that, when the surface litter and the surface soil are unraveled, the lower vegetation such as small shrubs, kaya, bamboo grass, etc. is weeded out and new litter and litter are roughly removed in the preceding stage. By doing so, the vegetation material can be vacuum-sucked mainly on the old deciduous leaves, and a vegetation material preferable for the vegetation surface and construction can be obtained.

Therefore, according to the present invention, as compared with the conventional sampling method in which a heavy machine such as a backhoe is mounted, the sampling area of the surface soil is not degraded and the existing vegetation is not adversely affected. It is possible to vacuum-collect the surface-layered leaves or surface-layered soil containing the leaves that are suitable for use in revegetation by using this as a vegetation material.

Since the collected vegetation material contains almost no gravel, there is no need to clean up the gravel, and the vegetation material is mainly composed of fallen leaves and is lightweight, so that it is easy to handle and work. However, since this vegetation material is mainly composed of deciduous leaves, it is possible to stock a large amount of it in a narrow space by pressing it, and by refrigerating it, it will be suitable for future greening plans. It is also possible to deal with.

Then, based on the vegetation material collected by the above method, at least one of a soil improving material, a water retention material and a fertilizer is mixed with the vegetation material (claim 2) to obtain a lightweight greening material. This makes it easy to handle the greening by spraying the greening material as a soil material on slopes, or by using the greening material in sandbags as vegetation sandbags.

[0017]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. 1 to 4 show one form of slope greening, and the construction site of the greening (slope in this embodiment) N
For example, the old fallen leaves 1 on the slope surface of the area A adjacent to and the fallen seeds a of the local vegetation contained therein are collected as the vegetation material 2, and the vegetation base material 3 is mixed with the vegetation material 2. As the greening material 4, the greening material 4 is sprayed on the slope N as a soil material, and the falling seed a of the vegetation is utilized in the adjacent area (extraction area of the surface layer defoliation) A so that the slope N is greened. ing.

Specifically, as shown in FIG. 2, existing lower-layer vegetation (for example, small shrubs, kaya, bamboo grass, etc.) is present in the surface-layer defoliation collection area A so as to be suitable for vacuum suction of the defoliation 1.
5 is trimmed, and the trimmed lower-layer vegetation 5 and litter 6 are roughly removed with a rake or the like, and more preferably, about the new litter 1a so that the old litter 1 suitable for use in revegetation is left. Also, roughly remove this with a rake.

Next, as shown in FIG. 3, the layer of the old deciduous leaves 1 (that is, the A ₀ layer containing the decomposed deciduous leaves) appearing in the collection area A is unraveled, The fallen seeds a contained in the above are used as the vegetation material 2, which is sucked by the vacuum suction means (see FIG. 1) 7 and stored in the storage tank 8.
To collect.

[0020] In case the construed this deciduous 1, as shown in Figure 3, the tip of the pipe made handle 10 for suction deciduous connected to a vacuum suction unit 7, the air casing 11 having an open bottom Case 1 is connected to this case 11
A nozzle 12 for blowing high-pressure air toward the leaf 1 in 1 is provided, and a high-pressure air supply hose 13 is connected to this nozzle 12, and the high-pressure air is blown in the case 11 so that the collection area A For example, the deciduous leaves 1 on the surface layer of the forest floor are disentangled over a depth of about 5 cm to 10 cm.

A high pressure air blowing nozzle 14 is also provided inside the pipe handle 10, and a high pressure air branch supply hose 15 is connected to the nozzle 14 to vacuum the leaf 1 by the vacuum suction means 7. The suction is assisted so that not only earth and sand but also large gravels are included as much as possible, and the fallen leaves 1 on the forest floor surface in the collection area A and the fallen seeds a contained therein are collected. ing.

The vegetation material 2 thus collected is loaded on the bed of the carrier 16 and transported to the slope N to be planted, and as shown in FIG. A net 17 for preventing runoff is stretched over N, and a necessary amount of vegetation material 2 and vegetation base material 3 are put into a stirring tank 19 of this using a spraying machine 18 such as an aeroceder. The stirred greening material 4 is sprayed from the nozzle 21 at the tip of the hose 20 onto the slope N at a thickness of, for example, about 5 cm to 15 cm, and the slope N is greened by the falling seeds a of the local vegetation.

Instead of the above-mentioned spraying construction, the soil or the soil and the vegetation base material 3 is previously set at the construction site (for example, slope) N.
Or a vegetation base material 3 alone to form a base layer, and then spray the collected vegetation material 2 2
It is also preferable to take the form of layer spraying, which makes it possible to carry out a large area greening construction with a small amount of vegetation material 2.

The above-mentioned vegetation base material 3 is a soil improving material,
At least one of water retention agent, organic compost, chemical fertilizer, vegetable fiber and the like is selected. Then, as the water retaining material, perlite, vermiculite, super absorbent polymer or the like is selected, and as the soil improving material, peat moss, bark compost or bentonite is selected.

The lower vegetation 5 cut off before the vacuum suction of the fallen leaves 1, the new fallen leaves 1a, the fallen branches 6, etc.
It can be crushed and effectively used as a bulking material for the greening material 4, and it is economical to use it as a bulking material. However, for the new leaf lla, this will turn into humus over time. , Need not be removed.

In the above embodiment, the vegetation material 2 is used.
Is collected, transported to an accumulation site, and mixed with the vegetation base material 3 to form a greening material 4.
Of the so-called seeding spraying method (a method of spraying the collected vegetation material 2 to the construction site N near the site, with little stock in terms of time or days), We are trying to restore the vegetation at an early stage, but since the main component of the vegetation material 2 is the old deciduous leaf 1, it is possible to stock a large amount in a narrow space by pressing this, and in addition to the greening plan of the future. As a measure, it is possible to store it in a refrigerator for a long time.

[0027]

[0028]

In the above embodiment, the target of greening due to local vegetation is the slope N at the road side, but, for example, a landslide area in a mountainous area due to a heavy rain can also be the target of greening. The sampling area A of the surface soil including 1 is
The collection area is not limited to the above-mentioned forest land, and for example, the development area of a new town where large-scale land development and the construction area such as roads are also collected.

That is, for example, when constructing a road or the like, when cutting a forest land where standing trees are growing to form a slope,
Alternatively, when developing a new town, surface soil containing defoliation before or immediately after felling of forest land is collected as a vegetation material, mixed with a vegetation base material, and used as slopes or land for construction. By spraying on the slopes, it becomes possible to reveer slopes and landslides with local vegetation.

The greening material 4 is not only used for the spraying method, but as shown in FIG. 5 , the greening material 4 is packed in a sandbag bag 22 to form a vegetation sandbag 23, which is appropriately stacked and used. Can be implemented using
Alternatively, FIG. 6 (A), the can also be used in the vegetation mat 24 is used as (B), the example, a method of shore protection greening.

That is, the revegetation work using the vegetation mat 24 is 2
The sheets 25 and 26 are appropriately joined to form the sheets 25 and
While forming a grid-like space P between 26, for example, the shore of a river is a construction site N for greening, and the construction site N is
This is a construction method in which the sheets 25 and 26 are stretched by the anchor 27 and the space P is filled with the green material 4, and the green material 4 according to the present invention can be preferably used for this. In both the vegetation mat 24 and the vegetation sandbag 23, the vegetation material 2 and thus the greening material 4 contains almost no soil or gravel, and the main component is the leaf litter 1, which is lightweight, which is excellent in terms of handling and workability. Will be things.

INDUSTRIAL APPLICABILITY As described above, the present invention uses, as a vegetation material, vacuum suction of surface layer litter or surface layer soil containing litter and falling seeds so as not to contain soil and large gravel as much as possible. The feature is that the greening material is obtained based on.

Therefore, according to the first aspect of the present invention, it is possible to obtain a vegetation material mainly composed of deciduous leaves, which is suitable for use in revegetation, in a lightweight form so as to be suitable in terms of handling and workability. Moreover, since the collected vegetation material contains almost no gravel, there is no need to clean up the gravel.Furthermore, since the vegetation material is mainly deciduous, it can be stocked in a large amount in a narrow space by pressing it. Alternatively, it is also possible to store in refrigeration so as to correspond to the future greening plan. At the same time, the high-pressure air spray damages the roots of existing trees.
It is suitable because it is difficult to avoid.

According to the second aspect of the present invention, the greening material can be obtained based on the vegetation material mainly containing deciduous leaves, and since the greening material is lightweight, the greening material is used as the soil material. As a greenery to spray on slopes,
The greening work in which the greening material is packed in sandbags and used as vegetation sandbags can be handled easily.
