Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention uses at least an organic soil conditioner, plant seeds, fertilizer, and a polymeric erosion inhibitor as materials, and mixes these with water and sprays them on a slope. Regarding

[0002]

2. Description of the Related Art Generally, various techniques for spraying a greening base material on a slope are known. For example, JP-A-2-47 according to the present application.
It is also disclosed in Japanese Patent No. 427. These base materials are agitated with water by a so-called batch method and sprayed onto the slope from a nozzle by high pressure air.

As is well known, various materials are known as greening materials, and the proportion of the materials is selected according to the soil quality and climatic conditions. Therefore, the greening material to be blended for each batch is predetermined.

However, it is difficult to install a weighing machine or the like at the greening site, which inevitably results in uneven mixing of the materials. Therefore, it may be possible to mix them in a predetermined ratio in advance, but this is inconvenient because the seeds germinate and the polymer-based erosion inhibitor is affected by rainwater during storage. In addition, it is troublesome to put in a batch that is strong and resistant to rainwater.

[0005]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a slope revegetation method capable of easily blending a revegetation material at a predetermined ratio on site and thereby obtaining a uniform revegetation base. is there.

[0006]

According to the present invention, at least an organic soil amendment material, plant seeds, fertilizer, and polymeric erosion inhibitor are used as raw materials, and these are mixed with water and blown onto the slope. In the slope revegetation method, the powdered granular polymeric erosion inhibitor and fertilizer are weighed and filled in a water-soluble plastic bag, and the bag, pre-weighed organic soil conditioner and pre-weighed plant seeds are weighed. And the water weighed in advance are introduced into the stirrer, the bag is dissolved,
The mixture is sprayed onto the slope from a spray nozzle.

[0007]

[Explanation of action and effect] Therefore, exactly one batch of water is stored in the tank, and when a bag filled with a powdery granular polymeric erosion inhibitor and fertilizer is put into the stirrer,
The bag is melted by the water in the stirrer. It is then mixed in the stirrer with one batch of pre-weighed organic soil amendment material and similarly weighed seeds, so that a given proportion of formulation is obtained. Therefore, a uniform greening base can be obtained by spraying.

Since the bag is soluble in water, it does not clog the nozzle. In addition, since a granular polymer erosion inhibitor is used, it can be stored in the bag for a long period of time and has no adverse effect on fertilizer.

The seeds and the soil conditioner are relatively easy to handle, and if several kinds of amounts are prepared in advance, they can be simply put in a predetermined amount in a stirrer on site. Similarly, several kinds of bags containing the erosion inhibitor and fertilizer may be prepared in advance.

Therefore, according to the present invention, a water-soluble bag containing a powdery and granular polymeric erosion inhibitor and a fertilizer in advance, plant seeds and an organic soil conditioner should be manufactured in a factory other than the site. The work efficiency of the greening method is improved.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION In practicing the present invention, it is not always necessary to measure each material in one batch, but a plurality of materials may be blended.

If necessary, other materials such as zeolite, cement, and filler may be filled in the bag, or they may be separately weighed and added in the same manner as the soil conditioner. And the water is supplied from the pump to the agitator,
The amount can be controlled by a timer.

The organic soil conditioner used in the present invention includes bark compost and peat moss. Further, the water-soluble plastic as the material of the bag is preferably polyvinyl alcohol, sodium polyacrylate, carboxymethyl cellulose, methyl cellulose, polyvinyl pyrrolidone, or the like.

The polymer-based erosion inhibitor may be a granular material and can be easily stored, and polyvinyl acetate compounds, polyacrylamide and the like are preferable.

The fertilizer may be an ordinary chemical fertilizer.

As plant seeds, exotic herbs (Kentucky 31 fescue, creeping red fescue, orchard grass, etc.) and woody plants (yamahagi, weasel hag, medhagi etc.) are used. It is a woody plant that finally establishes on the slope, but since the woody plant grows slowly, the sprayed base easily flows out due to rainfall. Can prevent erosion until it starts to exert its erosion prevention effect.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An apparatus for carrying out the present invention will be described below with reference to the drawings.

The spraying machine indicated by reference numeral 10 in its entirety is known per se and comprises a material charging section 11, a first stirrer 12 and a second stirrer 14 for the charged material.
In the figure, 13 is a prime mover.

On the other hand, the air hose 17 extending from the compressor 16 sends the raw material mixed with the feed head 15 of the second stirrer 14, that is, the green base material, to the nozzle 18 together with the compressed air and blows it onto the slope N. There is.

A submersible pump 20 is installed in the tank 19, and an electric wire extending from the generator 21 is connected to the submersible pump 20.
It is connected to the. A hose 23 from the submersible pump 20 extends to the first agitator 12. Further, conveyors 24a and 24b for feeding the material to the input section 11 are provided.

In the figure, E1 is a bag made of water-soluble plastic that is put into the tank 19, and contains an erosion inhibitor and fertilizer. E2 is the weighed plant seed and E3 is the weighed organic soil amendment.

Typical formulation examples of the greening base material used in the present invention are as shown in the table below.

[0023]

The first and second stirrers 12, 14 are arranged so that one batch of greening base material is prepared in advance.
While the base material in the stirrer 14 is being sprayed, the first stirrer 12 is stirring and mixing the next batch of the base material.

In the spraying work, as described above, 1
A bag E1 containing a batch-measured fertilizer and a powdery or granular polymeric erosion inhibitor, and a pre-weighed seed E2,
The organic soil conditioner E3 weighed in advance is placed on the conveyor 24a, and the charging port 11 is provided via the conveyor 24b.
And enters the first stirrer 12.

On the other hand, the water in the water tank 19 is sent to the first stirrer 12 by the pump 20. The amount can be measured by a timer (not shown).

1 which was stirred and mixed by the first stirrer 12
The batch greening base material is sent to the second agitator 14 via a gate (not shown). Meanwhile, the water-soluble bag E1 dissolves in water. Therefore, the mixing operation is performed uniformly.

The greening base material thus mixed is sent from the feed head 15 to the nozzle 18 by compressed air. When the work for one batch is completed, the first agitator 12 is operated.
Then, the greening base material is sent to the second stirrer 14 and the same work is performed.

[0029]

As described above, the present invention has the following excellent effects.

(1) Each material constituting the greening base material is pre-calculated for one batch, so that it does not become heterogeneous in the work for each batch.

(2) Since one batch of the polymeric erosion inhibitor and the fertilizer is weighed and put in a water-soluble plastic bag, it is sufficient to put the bag into the tank.

(3) Even if the water-soluble plastic bag is not melted and remains partially, it does not stick to the hose or nozzle and is not clogged, and will eventually melt during the spraying operation.

(4) Since the polymeric corrosion inhibitor is dissolved in water and sprayed for a short period of time, the degree of deterioration is small and the corrosion inhibition effect is improved.

(5) The work efficiency is improved.
