DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for stabilizing a slope such as an inclined slope facing an expressway or various facilities constructed by an open cut method or the like, or a steep slope having a possibility of collapse.

[0002]

2. Description of the Related Art In a conventional slope stabilizing method, wires are provided along a predetermined distance in a horizontal direction and a vertical direction on a slope, and the ends of the wires are stopped in a tension state via an anchor on the slope.

[0003] The crossing portions between the tensioned vertical wires and the horizontal wires are connected via cross clips, and the crossing portions and intermediate portions of the wires are supported on slopes via anchors.

Further, a net is laid on the stretched wire, and the net is fixed to the wire via a fastener such as a coil clip.

[0005] With the above-mentioned implementation, falling of rocks or the like is prevented by a wire or a combination of a wire and a net.

[0006]

According to the above-described slope stabilization method, the support of the wires along the vertical and horizontal directions with respect to the slopes is performed by the intersections of the wires and the anchors engaged in the middle of the wires. There is no strong stability. That is, the pressing force of the wire against the slope is weak.

[0007] Of course, the same applies to the case of a net used in combination.

Therefore, an object of the present invention is to improve the supporting force of a wire or a wire and a net on a slope,
This is to improve the stability of the slope.

[0009]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

In the embodiment of the present invention, a pressure receiving material A as shown in FIG. 1 is used.

The pressure receiving member A is composed of a hollow cone-shaped or pyramid-shaped pressure receiving plate 1 having an open lower surface, and a through hole 2 provided at the top of the pressure receiving plate 1. In order to measure the pressure, two pressure receiving plates 1 having an inner diameter and an outer pressure having different diameters are combined, but the number is not limited.

Although the top of the pressure receiving plate 1 is made to have a frusto-conical shape to stabilize the overlap, it is not necessarily limited, and the material is made of a synthetic resin in which a steel plate or a reinforcing material is embedded.

Next, a method for stabilizing a slope using the pressure receiving material A will be described.

As shown in FIG. 2 to FIG.
The vertical wire 12 and the horizontal wire 12 parallel to each other are arranged along with the end of the desired wire 12 on the slope 1.
1 is stopped via an anchor 13.

The above-mentioned anchor 13 is inserted into the slope 11 and, as shown in FIG.
1 and is inserted into the hole 41 and fixed while injecting a grant material 42 such as cement milk. The terminal of the wire 12 with respect to the anchor 13 is fixed by a known winding lock or a terminal fitting of the wire 12. 13 through,
Then, there is a method of stopping with a nut screwed into the upper end screw portion of the anchor 13 or the like.

The intersection of the vertical wire 12 and the horizontal wire 12 is connected via a clip 14.

The clips 14 are, for example, two holding plates 15 and are inserted into the holding plates 15 so that the holding plates 15
And a tightening tool 16 composed of a bolt and a nut that draws the bolt.

Thereafter, the pressure receiving material A is placed near a predetermined position of the wire 12 and the tensile material 17 fixed on the slope 11 is passed through the through hole 2.

The fixing of the tensile material 17 is performed by providing a boring hole 41 on the slope 11 as shown in FIG. 6, inserting the boring hole 41 into the hole 41, and injecting a grant material 42 such as cement milk into the hole.

Thereafter, the tension member 1 protruding from the pressure receiving plate 1
7 is fitted with a washer, and then the nut 18 is screwed in while tightening, and the wire 12 is pressed against the slope 11 by the pressure receiving material A.

Then, as shown in FIG. 4 and FIG. 6 , the pressure receiving member A is fixed to the slope 11 by screwing the tension member 17 and the nut 18.

The wire 12 is fixed (supported) to the pressure receiving material A by an appropriate means.

As shown in FIG. 4 and FIG. 6, the above-mentioned fixing means fixes the wire 12 with a projecting piece 31 projecting from the open rear edge of the pressure receiving plate 1 and a pressing piece 32 placed on the projecting piece 31. At the same time, a fastener 33 composed of a bolt and a nut is inserted into two opposing portions of the projecting piece 31 and the holding piece 32 with the wire 12 interposed therebetween, and the wire 12 is fixed to the pressure receiving material A by tightening. However, it may be fixed by a method other than the above, for example, via a clip.

As shown in the figure, the pressure-receiving material A may be filled with a self-hardening material B such as cement milk .

As shown in FIGS. 1 and 6, this filling method is performed from the injection port 3 provided in the pressure receiving plate 1, and the injection port 3 may be closed with the stopper 4 after the injection.

[0027]

Since the slope stabilization method of the present invention is constructed as described above, the wire can be pressed against the slope via the pressure receiving material, or the wire can be brought close to and along the slope.

Therefore, the wire can be stably supported, and a stable tension can be always maintained.
