DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spacer for a thick soil spraying method which is used when performing a thick soil spraying method for greening a slope or a bedrock.

[0002]

2. Description of the Related Art Conventionally, in order to green a slope or a bedrock, a thick layer of soil is sprayed on these surfaces. When spraying this thick layer of soil, a plastic or metal spacer is interposed between the slope and the net (lass net) to provide an interval between the net and the slope, Spraying the soil up and down.

[0003]

However, there is a problem that the plastic or metal spacer remains as foreign matter in the soil for a long time.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to make it easy to hold and maintain a soil, and to disassemble and return naturally after the soil is settled. The purpose of the present invention is to provide a spraying method spacer.

[0005]

According to the present invention, a spacer is interposed between a slope and a net, the net is laid with an interval from the slope, and the net is provided on the upper and lower surfaces of the net. In the thick layer soil spraying method for spraying the soil, the spacer,
It is characterized in that an organic soil improving material, an inorganic soil improving material, a fertilizer and an adhesive are mixed, and these are molded and solidified into a cylindrical shape.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The spacer 11 has the following a,
e, composed of the five types of materials shown in FIGS. A, organic soil amendment materials such as coconut, straw, corn, wood products,
This includes composted products made from pulp products and the like, and processed products obtained by composting natural resource products, residues, activated sludge, processing by-products, marine products, and the like. b, Inorganic soil amendments This includes black soil, peat, clay, and carbonized beer and pulp residues.

C, Water-retaining material This includes pulverized fibers, paper and the like containing a superabsorbent polymer. d. Fertilizers These are advanced chemical fertilizers, organic fertilizers, mixed processed fertilizers, animal and plant processed fertilizers, sludge fertilizers and the like. e. Adhesive This is to maintain the strength to withstand the impact when the anchor pin 12 is driven into the spacer 11, and includes a polymer-bonded resin, an organic processed bond, and the like.

The spacer 11 is formed by mixing these five types of materials, compression-molding into a cylindrical shape, and further heating and curing.
The length of the spacer 11 can be freely selected as required. In general, the thickness is set to about half the thickness of the laid soil 13. The shape of the cylinder is not limited to a cylinder, and may be a square or an ellipse. The inner diameter 11a (see FIG. 5) may be set according to the thickness of the anchor pin 12.

Next, the method of spraying thick layer soil will be described. First, a lath net 15 is temporarily laid on the slope 14.
The spacer 11 is inserted through a mesh of the lath net 15 at a desired position below the mesh, and the inner diameter 11
The anchor pin 12 is driven through the hole a, and the lath net 15 is fixed. The number and size of the anchor pins 12 used per m ² may be appropriately selected according to the situation at the site. FIG. 4 shows a standard fixing position, in which a spacer 11 is arranged in a circle with respect to a lath net 15 of 1 m square. This lath net 15 is a 50 mm wire having a diameter of 2 mm.
It was formed into a 50 mm mesh.

[0010] Then, as shown in FIG.
In order to fix 5, the anchor pin 12 penetrates the inside diameter 11 a of the spacer 11 and is driven into the slope 14 by the hammer 16. As a result, as shown in FIG.
5 is fixed to the slope 14 with an interval 17 corresponding to the height of the spacer 11.

Then, the soil 13 is sprayed on the space 17 below the lath net 15 and on the upper surface of the lath net 15 (see FIG. 1). Since the guest soil 13 has the lath net 15 holding a substantially central portion of its thickness, the lath net 1
Since 5 is fixed to the slope 14 via the anchor pin 12, the soil 13 is securely fixed to the slope 14.

After spraying the soil 13, the spacer 11 absorbs rainwater and the like and gradually softens, and the fertilizer (particularly, phosphorus and potash) melts out and penetrates the surrounding soil 13 to favor vegetation. Bring results. In particular, the above operation is continuously performed by the water retention capacity of the included water retention material. Furthermore, since the spacer 11 is composed of an organic and inorganic soil improving material, it is decomposed 100% and reduced naturally after several months.

The above embodiment has the following advantages. (1) The lath net 15 has the slope 1
4, a desired interval 17 can be reliably set with the slope 14. If various types of spacers 11 having different lengths are prepared, the interval 17 can be appropriately changed according to the thickness of the blown soil 13. (2) After the spraying operation is completed, the spacer 11 absorbs rainwater and gradually softens, and fertilizer (particularly, phosphorus and potash) melts out and penetrates into the surrounding soil 13, so that the vegetation has a good result. Bring. (3) Since the spacer 11 is made of an organic and inorganic soil improving material, it is decomposed 100% and reduced naturally after several months, and no foreign matter remains in the soil 13.

[0014]

According to the present invention, a spacer is interposed between a slope and a net, the net is laid with an interval from the slope, and soil is blown on the upper and lower surfaces of the net. In the thick layer soil spraying method, the spacer is formed by mixing an organic soil improver, an inorganic soil improver, a fertilizer and an adhesive, and molding and solidifying these into a cylindrical shape. An appropriate distance can be provided between the spacer and the spacer to facilitate the fixing and holding of the soil, and after the soil is fixed, the spacer is disassembled and can be naturally reduced.
