DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for stabilizing a soil by forming a pocket net when a growth base is sprayed (attached) on an inclined portion.

[0002]

2. Description of the Related Art As a conventional technique, there is a thick-layer-substrate spraying method in which a wire mesh is provided on an inclined portion and a vegetation material is sprayed on the wire mesh. There is a thick net construction in which a thick wire mesh is formed by knitting a wire mesh into a spring shape, and a thick wire mesh is attached to an inclined portion and a vegetation base material is sprayed on the thick wire mesh. There is a method of attaching a base to a bag in advance and attaching it to a slope.

[0003]

The thick layer base material spraying method is a method of forming a base by stretching a wire net and spraying thickly with a soil, and rainwater is not generated on a smooth or steep slope. The erosion due to flowing directly down the surface causes the base such as soil to be washed away and the plants to decline. Smooth slopes are slippery when snow accumulates, and are damaged by avalanches, damaging bases and plants. When steep and smooth slopes are subjected to freezing and thawing, the base froze and washed away, causing plant decline. The thick net method can make the base thick with a thick net, and the stability of the base is good, but the same phenomenon as the thick base material spraying method has occurred over time. A pocket-shaped bag is a device in which a base pocket is attached in advance and is hung from a shoulder of a slope. Because of its heavy weight, its location is limited to a gentle slope and a road near a road using heavy equipment such as a crane. The present invention has been made in order to solve such a problem.

[0004]

According to a first aspect of the present invention, there is provided a net having a support member in which support rods such as reinforcing rods and pipes are fixed to a continuous net at predetermined intervals using an adhesive or a fastening material. Hang the hanging material on the inclined part, secure the net with the support material to the hanging material so as to form a pocket in the horizontal direction by slackening the hanging material such as chain or wire, and attach the hanging material or the supporting material with the sub-anchor A pocket net that can be fixed, the pocket size can be arbitrarily designed according to the local shape such as inclination at any position, and the pocket can be installed according to the local shape, so the pocket can be securely installed in the horizontal direction Things. Furthermore, there is no hanging material attached to the supporting material net, so it is easy to manufacture and transport, so the supporting material has a staircase shape, and because there are no obstacles, it is easy to accumulate fallen leaves etc. and it is easy to snow The avalanche can be prevented by the snow and the growth base can be kept warm.

According to a second aspect of the present invention, a net with a supporting member is previously attached to a suspending auxiliary member at predetermined intervals to loosen the pocket net and form a pocket in a horizontal direction. You can form a pocket for the base,
Another object of the present invention is to make a factory by forming a pocket in advance with a suspending auxiliary material. The hanging auxiliary member is attached to the net with the supporting member in advance, so that the attaching operation at the site can be easily performed. In addition, it has a step shape with support material,
Since there are no obstacles, the accumulation of fallen leaves and the like is easy and the snow is easy, so that the snow can prevent the avalanche and keep the growth base warm.

[0006]

According to the first aspect of the present invention, a supporting member such as a reinforcing rod or a pipe is fixed to a continuous mesh at predetermined intervals by using an adhesive or a fastening material, and a mesh with a supporting member is previously suspended on an inclined portion. Tighten the support so that the net of the net with support is slackened and forms a pocket in the horizontal direction so that the net part of the net with support is loosened on the hanging material such as a chain or wire that is fixed from the shoulder and fixed with an anchor. It is a pocket net that stabilizes the growth base by fixing the material or support material to the slope with sub-anchors.

According to a second aspect of the present invention, a pocket net in which a net is formed in a horizontal direction so that a net portion of the net with a support member is attached to a suspending auxiliary member at a predetermined interval in advance so that the net portion of the net with a support member is slackened. It is a pocket net suspended from the upper part, and a suspension material or a support material is fixed to a slope by a sub-anchor to stabilize a growth base.

FIG. 1 is a view showing an outline of the present invention. In a main anchor 2 installed on a shoulder 1, a mesh member of a net 5 with a supporting member 4 is loosened on a hanging member 3 such as a chain. FIG. The growth base is thrown into or sprayed into the pocket 6 in which the net portion of the net 5 with the support member 4 is loosened, and is stabilized. FIG. 2A is an example of a case where the device is installed on the slope 1 'or the like. FIG. 2b Place main anchor 2 on shoulder 1. FIG. 2c The net 5 with the support 4 is fixed to the main anchor 2 and suspended. FIG. 2D A hanging member 3 such as a chain is fixed to the main anchor 2 and suspended. FIG. 2e
The net portion of the net 5 with the supporting member 4 is loosened by the hanging member 3 to bind the supporting member 4 to form the pocket 6. FIG. 2f The hanging member 3 and the supporting member 4 are fixed by the sub-anchor 2 '. 2g Spray the growth base 7 on the pocket 6. FIG. 3 shows a supporting material 4 and a net 5
This is an example of a method for fixing. The supporting member 4 is preferably made of mesh, resin, wooden L-shaped steel bars, pipes, logs, or the like, and may be a member capable of holding the base 7 by being tightly attached to the suspending member 3. In the case of a reinforcing bar, the wire diameter is from 6 mm to 22 mm. A degree is desirable. The mesh 5 has a mesh size of about 5 mm × 5 mm to 30 mm × 30 mm, a wire diameter of about 0.5 mm to 3 mm, and is preferably made of steel, resin or natural fiber. FIG. 6 is a diagram in which a C-type resin coupling 8 is attached to the reinforcing bar 4 shown in the figure as a fixing method. The present invention is not limited to this, and may be fixed by sewing, an adhesive or a nail. Since these are different depending on the material and the shape, they may be fixed by various methods. In some cases, it may not be fixed. FIG. 4 shows an example of a method for fixing the support member 4 to the chain 3. Chain 9 with hook on support 4
FIG. 2 is a view attached to a main chain 3 which is a hanging material. The material of the chains 3 and 9 may be steel, resin, or the like. The wire diameter is about 5 mm to 15 mm, and the main chain 3 is large to receive a load. A small one is used to bear the load of the growth base 7 of the pocket 6. FIG. 5 shows a structure in which a heat insulating material 10 is attached to a net 5 with a support member 4. The purpose of the insulation 10 is to prevent the growth base 7 from drying out,
It is intended to reduce temperature fluctuations and increase water retention, and it is possible to store water depending on the installation method. The installation location includes the front of the net 5, the space between the nets 5, the inside, and the like. The length is adjusted, and there are I type, L type, J type, and the like. The thickness is about 1 mm to 10 mm, and the material is often made of resin. FIG. 6 shows a second embodiment of the present invention in which a hanging auxiliary member 3 'is attached to a net 5 with a supporting member 4 to form a pocket of the net 5 in advance. A suspending auxiliary member 3 ′ such as metal is attached between the supporting members 4 of the supporting member 4 attached net 5. FIG.
Is a diagram in which a wire (made of steel) or a rope (made of resin, natural fiber) is used as the suspension aid 3 ′. In addition to this, there is one using a chain.
