Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vegetation with a greening material accommodating portion used for greening a cut slope or an embankment slope.
It is those that.

[0002]

2. Description of the Related Art In recent years, as interest in environmental problems has increased,
Even in steep slopes, northward slopes and cold regions where it is difficult for plants to grow, their greening has been eagerly awaited. Therefore, as a vegetation used for revegetation of such steep slopes, there are provided seeds, fertilizers, soil conditioners, superabsorbent resins, and those provided with a storage member densely filled with revegetation material including horticultural soil. ing.

However, in the above-mentioned vegetation body, the housing member is densely filled with the greening material, and there is no space for growing the sprouts of the germinated plant. Therefore, unless the housing member is exposed to the elements such as wind and rain and broken, the bud-shaped plants are hindered by the housing member and cannot grow, and there is a problem that the appearance rate of young plants and the growth rate of plants are low. It was

When the slope of the north-facing inclined surface exceeds 35 degrees, the amount of solar radiation in winter is extremely lower than that in flat land, and the environment for germination and growth of plants is severe.

Furthermore, in cold regions, the buds that have been forcibly sprouted from the greening material storage section are often exposed to severe environments such as low temperature, frost, and thaw water and die.

On the other hand, the greening material to be filled in the accommodating portion is a mixture of seeds, fertilizers, soil improving materials, etc., but the soil improving materials vermiculite, perlite, etc. are lightweight and bulky, and other greening materials are used. Similar to the above, when measured by weight, the fluctuation of the volume is large. As a result, the seeds, fertilizers, etc. were not uniformly blended, resulting in waste of the greening material, which also contributed to poor growth.

[0007]

Therefore, the present invention solves problems such as poor growth of plants on steep slopes and northward slopes, withering immediately after germination in cold regions, and uneven filling of greening materials. With the goal.

[0008] To achieve this object, the greening of the present invention
For vegetation with material storage , two sheets should be bonded together.
By means of the above, a bag-shaped greening material accommodating portion between the above two sheets
Is formed, and the angle of repose is approx.
Greening materials (6) below 30 degrees germinate and grow plants
It is housed with a long space (7) left.

In another form of vegetation, the green material storage section is made of two or more kinds of materials having different decomposition rates.

[0010]

In the vegetation having the above-mentioned greening material accommodation section, there is always a space on the surface of the greening material (that is, the upper part of the accommodation section), and this space is maintained even after the construction of the vegetation. Therefore, even if the vegetation construction surface is a steep slope having a slope of 30 degrees or more, and even if it is a north-facing slope, the germination / growth space of the plant is secured, so that the germinated plant is excellent. grow up.

In addition, the above-mentioned space exerts a greenhouse effect, and the germinated plants are protected therein. Therefore, the plants after germination are not immediately exposed to the outside air and grow well even in cold regions.

If the green material storage unit is made of two or more kinds of materials having different decomposition rates, the germinated plants in the storage unit can gradually adapt to the natural environment.

[0013]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. 1 and 2 show an implant 1 according to the present invention. In the vegetation body 1, a space for accommodating a greening material described below, that is, a bag-shaped accommodating portion 2 is formed between the sheets 3 and 4 in a predetermined pattern.

As the sheets 3 and 4, thin sheets such as paper, a sheet obtained by mixing peat moss or bark with pulp, and a non-woven fabric are preferably used. The sheets 3 and 4 may be made of materials having different decomposition rates. As a material having a slow decomposition rate, for example, a synthetic resin such as polypropylene, an ultraviolet ray-deteriorating resin, a biodegradable resin, or a net made of natural fiber is preferably used. On the other hand, as a material having a high decomposition rate, pulp paper and non-woven fabric are preferably used. These materials are preferably bonded by an appropriate bonding means such as an adhesive or heat bonding.

As shown in the figure, it is preferable to attach a net 5 made of a bendable metal wire or a synthetic resin string on the upper sheet 3. The method of attaching the net 5 is not limited to adhesion, and a physical locking tool may be used.

The greening material 6 contains, in addition to seeds, a fertilizer, a soil improving material, a super absorbent resin, etc., which are appropriately selected according to soil conditions, and are mixed so that the angle of repose is about 30 degrees or less. There is. The angle of repose refers to the angle of inclination of the side surface when sand, debris, or powder is gently deposited in a conical shape.
990), for example, the angle of repose of dry clay is 2
It is known to be 0-37 degrees. When the greening material 7 is mixed, the deposition angle is measured for each of a plurality of samples in which the soil improving material and the like are appropriately combined so that the angle of repose is 30 degrees or less.

As shown in FIGS. 3 and 4, the volume of the accommodating portion 2 is a predetermined amount on the surface of the greening material 6 when a predetermined amount of the greening material 6 mixed as described above is stored. Sano space (germination / growth space) 7 should be formed. The volume of the space 7 is set to a size in which a seedling grown from seeds can grow.

As shown in FIG. 3, the vegetation body 1 is laid on a construction surface (slope) 8 such as a slope so that the lower sheet 4 is in contact with the soil and the net 5 is on the upper side. Fixed at 9. At this time, since the replanting angle of the greening material 6 in the accommodating part 2 is 30 degrees or less, the surface inclination angle of the greening material 6 is naturally 30 degrees or less, and the plant growth space is on the surface. 7 is formed.

Therefore, as shown in FIG. 4, when the seeds contained in the greening material 6 germinate, the buds grow in the space 7 of the accommodating portion 2 while being protected from the severe external environment. That is, the space 7 of the housing portion 2 exhibits the greenhouse effect.

The lower sheet 4 decomposes early by physical contact with soil. To that end, the plants spread their roots to the construction soil and settle there. On the other hand, the upper sheet 3
Is gradually exposed to the natural environment of the sun and rain winds and decomposes, allowing the foliage of germinated plants to grow. Note that the decomposition of the sheet involves not only the above-mentioned natural environment but also microorganisms contained in soil.

As described above, when the sheet is made of materials having different decomposition rates, the decomposition of the sheet occurs gradually or stepwise over a long period of time. Therefore, not only the greenhouse effect of the storage unit 2 is exerted for a long time, but also the greening material 6
Can be stably held in the housing portion 2 for a long period of time, which can further promote the growth of plants.

A method for manufacturing the vegetative organism 1 will be described. FIG. 5 shows an in-vivo manufacturing apparatus 10. In this manufacturing apparatus 10, the lightweight soil improving material 12 such as vermiculite and perlite contained in the container 11 is volume-measured by a conveyor 14 having a measuring cup 13. Weighed soil conditioner 1
2 is supplied to the belt conveyor 16 via the chute 15 in the form of a strip. The belt conveyor 16 is provided with a plurality of first partition plates 17 arranged at predetermined intervals in the axial direction of the conveyor 16, whereby the strip-shaped soil improving material 12 is divided into a plurality of lumps. .

The greening materials 18 other than the soil improving material 12 are weighed by a hopper 19, and the soil improving material 12 is divided into predetermined amounts.
Are dropped on each chunk of. The soil improving material 12 and the other greening material 18 are mixed by the vibration applied from the conveyor 16 and again divided into a plurality of lumps by the second plurality of partition plates 20 and then dropped onto the sheet 22 via the chute 21. To be done.

The sheet 22 is unrolled from the unrolling roll 23 and wound around the winding roll 25 via the roll 24. On the other hand, another sheet 26 that constitutes the vegetation together with the sheet 22 is wound around a roll 27. And
The sheet 26 fed from the roll 27 is superposed on the sheet 22, and the heat roller 28 disposed in the middle of the rolls 23 and 24 and the sheets 22 and 26 on the heat roller 28.
The sheet is sandwiched between the pressing rollers 29 facing each other through and is heat-sealed at a predetermined interval to form a housing portion. The biasing force of the pressing roll 29 is given by the spring 30.

When the net 6 is attached to the vegetation body 1, the net may be later attached to the vegetation body manufactured as described above, or the net may be previously attached to the sheet 26. A net is supplied between the heat roller 28 and the pressing roller 29 to provide the sheet 26 during the heat sealing.
May be integrated with.

In the above description, the accommodating portion for the greening material is formed between the two sheets. However, the greening material is accommodated in the cylindrical body made of the water-decomposable sheet, and this cylindrical body is formed, for example, by a known method. It may be attached to a net formed by double Russell knitting. In this case, as in the above-described embodiment, the greening material is mixed so that the angle of repose thereof is 30 degrees or less, and the volume of the containing portion is a space in which seedlings can grow on the surface of the greening material contained therein. The size should be such that

It is preferable to fill the above-mentioned cylindrical housing portion with the greening base material using the apparatus shown in FIG. In this device, the soil conditioner 1 volume-measured as described above is used.
Another greening material 18 weighed 2 is supplied onto the conveyor 16 and then dropped from the conveyor 16 into the cylindrical body 31. In the case of this device, since the filling state and filling amount of the greening material in the cylindrical body 31 can be visually observed, it is possible to easily form a space in the housing portion.

[0028]

EFFECTS OF THE INVENTION As is clear from the above description, the vegetation with a greening material accommodating portion according to the present invention has a space in which at least young plants can grow, and a plurality of greening materials to be filled are rested. It is compounded so that the angle is 30 degrees or less. Therefore , after the construction, regardless of the slope angle, the greening material in the accommodating portion has the effect of maintaining a slope on the surface that is good for plant growth. In addition, since the space formed on the greening material exerts the greenhouse effect, the plant is not exposed to the outside air immediately after germination, and the plant can be firmly established.

Further, if the storage section is made of two or more kinds of materials having different decomposition rates, it gradually becomes a natural environment such as a glass greenhouse, a net room, and a field, which is generally used in the cultivation of agricultural crops. The same action and effect as the operation of acclimatizing can be obtained. In addition, since the decomposition of the storage part progresses slowly, the extension of the root system prevents the flow of greening materials, promotes the foliage of the plant, and has the effect of maintaining vegetation for many years.
