Abstract

PURPOSE:To improve the adhering property of a soil spraying material to the wall of a slope as well as the germinative and growth properties of seeds by mixing rock wool into the soil spraying material. CONSTITUTION:Seeds for greens-planting work, back compost, peat moss, fertilizer, and an adhesive, which are being used conventionally, are mixed with beaten rock wools of a length of 10-30mm. to obtain a spraying material. When the spraying material is sprayed onto the 10m<2> wall of a steep slope by a cement mortar sprayer, for example, the run-off of the spraying material does not almost take place.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the improvement of soil spraying materials for greening the remains of excavated mountains.

Conventionally, soil spraying containing seeds was used to spray and sow seeds on relatively steep slopes left behind after mining rocks, broken earth, etc.; Moreover, when the slope was made of bedrock, in order to improve the adhesion of the material to the bedrock, the soil spraying method used to spread a net over the bedrock and then spray the material. However, with conventional soil spraying that contains park compost, peat moss, fertilizer, adhesive, and mountain sand, the materials do not get entangled in the net enough and often peel off due to wind and rain, and often do not peel off. Even if the soil is sprayed with soil, the water retention of the material is not sufficient, so the germination rate of seeds mixed with the material is low, and even if they germinate, they grow slowly. Furthermore, depending on the conditions of the remaining area, it may be necessary to set up a net, which is a dangerous task. As a result of extensive research in order to solve the above-mentioned drawbacks, the present invention has found that by incorporating rock wool into the material for spraying soil, it has good adhesion to the remaining soil and good seed germination and growth. has developed a material that can be sprayed onto soil that does not require the installation of nets on rock walls.

The materials used in the present invention include conventionally used seeds for greening, park compost (dead leaf compost), peat moss, fertilizer,
It is a mixture of adhesive and rock wool.

Seeds may be appropriately selected from grass and other conventionally used seeds. Water retention or moisture absorption? Park compost and peat moss can be used as fertilizers, and commonly available commercially available fertilizers include "Kinotsu S
” Canadian put moss (imported product). The fertilizer required for germination and growth is neither granular nor liquid, and may be mixed with other materials in advance, but preferably,
Granular chemical fertilizers are good. As the adhesive, a conventionally used adhesive such as ``Cricoat'' manufactured by Kurita Industries ■ can be used. Rock wool should be used at 1,000 ml (5404), but spraying should be done at 10-30 ml to make it easier to create the strips.
It is best to use cotton that has been loosened to about ++.

In addition, JI8A (5404), which is removed during rock wool production,
) can be used even if it has thick momme fibers or has a lot of granules (generally called shot). Conventionally, items containing this particulate matter were thrown away, so this is an effective use of resources. In addition, conventional spraying for soil has included mountain sand in the material, but with the product of the present invention, mountain sand can be used.
Furthermore, crushed stone dust (less than 5 pieces) can also be used, making effective use of resources. In the spraying for soil of the present invention, the approximate blending ratio of each material used is, for example, when using grass as seeds, the weight ratio of seeds is 0.1 to 1.0%, and park compost is 70 to 85%. %, peat moss 5-15%, chemical fertilizer o,
-,,3 to 1:0%, adhesive 0.2 to 1.0%, and rock wool 8 to 15%. These include mountain sand or crushed stone dust)
It may be blended in an amount of 30 to 50%.

If the remaining area is rock, the slope is steep with an angle of 45 degrees or more, and there are no ledges, it is necessary to install a net.

In addition, if the remaining rock is rock, the steeper the slope or the fewer the unevenness, the more preferably the blending ratio of rock wool is increased.

The present invention will be specifically explained below using Examples.

Example (1) Grass seeds o, s were placed on a limestone rock wall with an inclination angle of 60°
V4, park compost 300Kp, peat moss 40Kf, as fertilizer, mix Konoshima Kasei (Kiku's "Advanced Kasei" (fast-acting) IKg and the same company's [High Control 100j (slow-acting) 1.25 to 9 to make !25Kg, As an adhesive, I made a material for spraying soil using 2Kf of Kurita Kogyo's 0710J and 50Kg of Rock wool, added 101% water to this, and used a machine to spray mortar for 10N. Although the slope was steep, we did not use a net because there were uneven spots in many places.

After the spraying, there was about 10 million rainfalls in about a week, but there was almost no spillage of material during the spraying. When the sprayed plants were observed 3 months after construction, they had sprouted all over and the green leaves had grown to a length of approximately 300 m+.

Comparative Example - On the same day as the example, conventional soil spraying used 0.5 Kp of grass seeds, 300 Kg of park compost, 40 Kg of peat moss, and Konoshima Kasei's "Kokoku Kasei" as fertilizer. control 100] to 1.2
5Kg, adhesive manufactured by Kurita Industries ■ [Krikoh] 07
A mixture of 10J'e 2 K9° and 250Kgt of mountain sand was mixed, and 101tl of water was added thereto, and the mixture was sprayed for 10 m'' using the same spraying machine as in the example.

As in the example, when observed after 3 months, some soil had washed away due to rainfall, and the germination status was about 85% compared to the example because germination did not occur in the areas where the soil had flowed out. The green leaves were about 200 +++ m, which was significantly inferior to the example.
