Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vegetation material for vegetation spraying and a method of vegetation used for stable protection of slopes of soil quality.

[0002]

2. Description of the Related Art Generally, on slopes of soil such as hillsides formed by road construction and land development, plants are vegetated and greened in order to protect and preserve the landscape. There is. Then, in performing such greening, to the organic soil consisting of peat moss and bark compost of plant fibers, so as to spray the greening sprayed vegetation material mixed with seeds and fertilizers on the slope by a wet spraying method. ing.

More specifically, as the conventional organic soil, for example, those shown in No. 4 and No. 5 of the following Table 1 are used. The organic soil of No. 4 is peat moss of plant fibers and bark compost and A mixture of Nenisanso (perlite manufactured by Mitsui Kinzoku Perlite Co., Ltd.) with an apparent specific gravity of 0.336 g / cc was used, and water was added to this mixture to give an overall apparent specific gravity of 0.5 to 0.65 g / c.
The organic soil of No. 5 has an apparent specific gravity of 0.414 g consisting of peat moss and bark compost.
/ Cc mixture was used, and water was added to this mixture to give a total apparent specific gravity of 0.57 to 0.72 g / cc.

[0004]

[Table 1]

Further, the following two wet spraying methods are mainly used as the greening method for the soil quality slope. That is, the above organic soil, seeds, fertilizer, water, etc. are kneaded in a tank to form a green sprayed vegetation material, and this green sprayed vegetation material is sent to a spray nozzle by a pump, and a compressor is provided at the discharge port of the spray nozzle. From the so-called squeeze type pump spraying on the soil slope while scattering the greening sprayed vegetation material by the air from,
This is a thick-layer wet spraying method using a so-called mortar spraying machine in which the above-mentioned greening sprayed vegetation material is sprayed directly on the soil quality slope by air from a compressor. In addition to the above-mentioned wet spraying method, without using the water, the organic soil, seeds, fertilizer, etc. are kneaded with a mixer to form a greening sprayed vegetation material. There is also known a so-called dry-type spraying method in which water is sprayed to the spray nozzle by spraying, and water is sprayed at the discharge port of the spray nozzle onto the slope of the soil, but such a dry spraying method is shown in Table 1 above. As described above, since the overall apparent specific gravity of the green sprayed vegetation material is large, in order to send the green sprayed vegetation material to the spray nozzle, a large air pressure is required, that is, a large compressor is required, and its transportation and It is not generally used because of problems such as temporary construction being difficult.

[0006]

However, in the above greening and sprayed vegetation material, as shown in Table 1, the overall apparent specific gravity is about 0.5 to 0.7 g / cc and the weight is heavy. Therefore, there is a problem that transportability and workability are poor. Of the wet spraying methods adopted as the greening method, the squeeze pump was used to spray the soil quality slope after kneading the greening sprayed vegetation material in the tank, and the tank became empty. Sometimes it is necessary to knead again the greening sprayed vegetation material and spray it, so continuous spraying work is not possible and it is extremely inefficient, while the wet spraying method using a mortar sprayer Is a large volume and weight of the mortar spraying machine itself,
Moreover, it is necessary to attach a compressor, which causes a problem that the entire apparatus becomes large.

The present invention has been made in view of the above problems, and a first object of the present invention is to provide a planting material for greening and spraying which is lightweight and excellent in transportability and workability. The second purpose is that it is possible to adopt the dry spraying method by using a lightweight green vegetation material, and the efficient spraying work is performed while downsizing the entire device as compared with the case of using the wet spraying method. It is to provide a greening method that can be done.

[0008]

In order to achieve the above object, in the first invention, an apparent specific gravity of 0.13 to 0.3 g / cc of organic soil, which is the main component of the greening sprayed vegetation material, is used. is there. Further, in the second invention, the apparent specific gravity is 0.1
The green spraying vegetation material containing 3 to 0.3 g / cc of organic soil as a main component is sprayed onto the construction target surface by a dry spraying method.

[0009]

[Function] As described above, the apparent specific gravity of the organic soil, which is the main component of the vegetation material for greening, is set to 0.13 to 0.3 g / cc, which reduces the weight and improves the transportability and workability. It will be excellent. In addition, by using the above-mentioned lightweight green planting vegetation material and spraying this greening plant vegetation material on the construction target surface by the dry spraying method, compared to the case where the wet spraying method is used, the overall size of the device is smaller. And efficient spraying work can be performed.

[0010]

EXAMPLES Hereinafter, the greening and spraying vegetation material according to the first aspect of the present invention will be described with reference to specific examples. First, as the organic soil that is the main component of the greening sprayed vegetation material according to the present invention, the plant fibers peat moss, bark compost, topco perlite (manufactured by Showa Chemical Industry Co., Ltd.) and bermlite 1W (manufactured by Nissan Sangyo Co., Ltd.) are used. Used and mixed with each other in the compounding ratio as shown in the following Table 2, the apparent specific gravity is 0.134 to 0.243 g.
/ Cc was prepared. In Table 2 below, the apparent specific gravity was determined based on the weight per liter by letting the organic soil loosen and allowing it to fall naturally from the upper side of the 1 liter cylinder.
