Description

The present invention relates to a slip-prevention structure, and by mooring a resin member that is particularly lightweight and can be transported manually by substituting a standing tree that grows naturally on the slope as an anchor material, it is possible to quickly and reliably construct a steep mountain. Regarding anti-slip structures.

In natural disasters such as falling rocks and debris flows, rock masses and driftwood may remain on the slopes after the disaster occurs. Since these slope residues are not fixed to the ground, they are in an unstable state, and there is a possibility that they will slide down the slope due to subsequent rain or the like and cause a secondary disaster.
Conventional techniques related to measures against slope residues include a rope hooking work (Patent Document 1) in which a wire rope is hung on the surface of a rock mass and moored with an anchor, and a rooting mortar is injected between the rock mass and the slope. There are root hardening work (Patent Document 2) for fixing to a slope, fence installation work for capturing rock masses and drifting trees with a standby fence installed on a slope, and the like.

The prior art has the following problems.
<1> There are many metal members such as steel pipe columns, wire ropes, wire mesh, and shaped steel, and the number of parts is also large. In addition, heavy equipment such as leg hammers and compressors are required for placing columns and anchors. Since it is not possible to manually carry a large number of these heavy parts and materials into steep mountainous areas, it is necessary to install large equipment such as cranes and monorails in advance. Therefore, the installation requires a long construction period and a high construction cost.
<2> In order to effectively capture or moor the slope residue, it is necessary to drive columns, anchors, etc. deep into the ground. In addition, it is necessary to assemble a large number of metal members locally. Therefore, it takes a long time and labor for installation.
<3> From the above, the construction period is long and safety cannot be ensured in a short time, regardless of the emergency countermeasures aimed at preventing secondary disasters.

An object of the present invention is to provide an anti-slip structure capable of solving the above problems.

The anti-slip structure of the present invention consists of a fiber-coated net that covers the slope residue and a resin that extends horizontally through the mesh of the coated net along the upper and lower sides of the coated net. The extension rope and a plurality of anchor materials that fix both ends of the extension rope to the slope are provided, and by using a standing tree that grows naturally on the slope as the anchor material, the slope residue is removed by the pull-out resistance of the root system of the standing tree. It is characterized by being configured to be moored on a slope.

The anti-slip structure of the present invention includes a resin fixing rope that communicates with the mesh of the covering net and extends in the inclination direction of the slope, and both ends of the fixing rope may be fixed to the slope with a plurality of anchor materials. ..

In the anti-slip structure of the present invention, the extension rope and / or the fixing rope is made of a blade rope, and the tip of the blade rope wound around the outer circumference of the anchor material is woven into the mesh of the blade rope to form the extension rope and / or the fixing. The end of the rope may be fixed to the anchor material.

Explanatory drawing of the slip prevention structure of this invention. Explanatory drawing of Example 2. FIG.

Hereinafter, the anti-slip structure of the present invention will be described in detail with reference to the drawings.

[Slip prevention structure]
<1> Overall configuration (Fig. 1).
The slip prevention structure 1 of the present invention is a structure for preventing the slope residue A arranged on the slope from slipping.
The anti-slip structure 1 is composed of a covering net 10 that covers the slope residue A, two extension ropes 20 that extend horizontally along the upper and lower sides of the covering net 10, and a standing tree that grows naturally on the slope. At least a plurality of anchor materials 30 are provided.
In this example, two fixed ropes 40 extending in the inclined direction of the slope along the covering net 10 are further provided.
The extension rope 20 and the fixing rope 40 communicate with each other through the mesh of the covering net 10, and both ends extending to the outside of the covering net 10 are fixed to the slope by the anchor material 30.
The anti-slip structure 1 of the present invention is lightweight and can be manually transported because all the parts to be transported (covered net 10, extension rope 20, and fixed rope 40) are made of resin products. In addition, it does not require special tools and can be constructed with a cutter or scissors.

<1.1> Slope residue.
The slope residue A in this example is a rock mass and driftwood.
However, the slope residue A, which is the subject of the present invention, is not limited to rock masses and driftwood, but includes all objects that are not fixed on the slope and are in danger of slipping down.

<2> Covered net.
The covering net 10 is a net that covers the slope residue A and holds it down on the slope.
In this example, a polyester Russell knitting net is used as the covering net 10. The polyester Russell knitted net is lightweight and highly elastic, and even if it is partially cut, fraying does not spread from the cut part.
However, the material and structure of the coated net are not limited to this, and other fiber nets may be adopted.
When the area covered by the covering net 10 is large, a plurality of covering nets 10 may be combined and a fiber rope may be communicated and connected to the mesh on the side side of the adjacent covering net 10.

<3> Extension rope.
The extension rope 20 is a rope that fixes the covering net 10 to the slope.
In this example, a polyester blade rope is used as the extension rope 20.
The blade rope is a double-structured rope in which a core in which fiber threads are bundled is covered with a plurality of strands, and has both flexibility and high shape retention, and the end is wrapped around the outer circumference of the anchor material 30. By knitting into a mesh (eye processing), the anchor material 30 can be surrounded and connected in a loop shape.
However, the extension rope 20 is not limited to the blade rope, and other fiber ropes may be adopted.

<4> Fixed rope.
The fixed rope 40 is a rope that positions the covering net 10 in the horizontal direction.
Since the covering net 10 is held by the horizontal stretching rope 20 communicating with the mesh, it can slide in the horizontal direction along the mesh. Therefore, by communicating the fixing rope 40 with the mesh along the vertical direction of the covering net 10 and fixing both ends to the anchor material 30, the horizontal movement of the covering net 10 can be restricted and positioned.
In this example, the same blade rope as the extension rope 20 is used as the fixed rope 40.

<5> Anchor material.
The anchor material 30 is an anchor element moored to the slope residue A slope via the extension rope 20 and the fixed rope 40.
The present invention has one feature in that a standing tree that grows naturally on a slope is used as the anchor material 30.
Since the standing trees on the slope have deep and wide roots in the ground of the slope, by utilizing the pull-out resistance of this root system, the slope residue A can be applied to the slope without the need for placing anchor material. It can be moored reliably.
Further, by using the standing tree as the anchor material 30, it is not necessary to transport the anchor material to the site, and the equipment for placing the anchor material is also unnecessary.

<6> Auxiliary rope.
The auxiliary rope 50 is a rope that holds between the upper and lower extension ropes 20 in the covering net 10 (not shown).
In this example, the same blade rope as the extension rope 20 is used as the auxiliary rope 50.
When the area of the covering net 10 is large, or when the slope of the slope is steep, the mesh of the covering net 10 is connected in the horizontal direction and both ends are connected to the anchor material 30 to form the slope residue A of the covering net 10. Increase mooring power.
The auxiliary rope 50 is not an essential component.

[Example of installing in a valley]
The anti-slip structure 1 of the present invention can also be installed in a valley (Fig. 2).
In the canyon, slope residue A is deposited on the canyon sandwiched between the canyons.
Therefore, using a standing tree on the shore as an anchor material 30, a covering net 10 and two extension ropes 20 are laid horizontally between the shores to suppress the front surface of the slope residue A, and two fixed ropes 40 are laid on the shore. The covering net 10 is held by hanging it in an inverted eight shape from the top to the valley floor.
As a result, it is possible to effectively prevent the slope residue A from slipping down along the valley floor.
