Description of the Related Art As an avalanche and rockfall prevention facility, fences (including those with wire mesh) and triangular pyramid-shaped frames are installed on the slopes (slopes) where there is a risk of avalanche and rockfall, and these are suspended. A rope (cable) is used to hang it with an anchor fixed to the upper part of the slope.

ことが一般であった。Since a load such as a suspension rope, a suspended object and snow and rocks acts on the anchor, it is necessary to firmly install the anchor on the ground. Therefore, in the past, for example, when a suspension fence is taken as an example, as shown in FIG. 1 (a), the anchor AC is erected vertically to the horizontal portion HZ of the forehead, or as shown in FIG. 1 (b). It was general that the slope was erected vertically to the horizontal part HZ 'where the step was cut and the suspension rope RP led from the structure G on the valley side was connected to the top of the anchor AC.

確保が必要となる問題があった。However, since the anchor AC tends to tilt toward the front side with the lower end as a fulcrum and collapse the front soil under load, in order to secure a resistance soil amount for preventing the front surface of the anchor AC from collapsing, A certain width from the shoulder to the front (generally 2
(m or more) a is required, and there is a problem that it is necessary to secure a wide area of land.

理作業の能率とコストが高くなるという問題があった。Further, in any of the prior arts, since it is necessary to guide and connect the suspension rope RP to the horizontal portions HZ and HZ 'having the front face width a, the rope length used becomes large, and the cost is correspondingly high. In addition, there is a problem that construction such as unloading at the site becomes difficult. Further, usually, many avalanche and rockfall prevention means are arranged on the slope, but when performing maintenance work such as maintenance, inspection, repair, and replacement after completion, many anchors AC are placed on the horizontal portion HZ of the slope. Since it is installed in a concentrated manner, it is difficult to determine which avalanche or rock fall prevention means is an anchor, which requires time and labor, which increases the efficiency and cost of maintenance work.

In the case of the type in which the anchor AC is formed vertically, the excavation work on the slope is indispensable, resulting in an increase in cost and risk of collapse of the slope due to stimulation in the excavation work. there were.

間と手間がかかる問題があった。Another anchor format is shown in FIG. 1 (c).
Although the anchor AC is also arranged at 90 degrees with respect to the slope of the slope SL as described above, in the case where the slope is strong, the working machine is maintained so as not to slide down from the slope, and the accurate vertical It is difficult to perform the driving work, and there is a problem that it takes time and labor.

Even if the range is carefully managed, if the construction angle deviates downward from the reference angle perpendicular to the slope, the front surface of the anchor AC may fall and the anchor function may be lost. From this,
The form of (c) is limited to the case where the ground is rock, and the anchor AC must also use a chemical anchor (a system in which resin fixing is used in combination).

って荷重を支える。In any of the obtained anchors, the bearing plate 4 connected to the anchor body 1 has an inclination angle θ.
The arm 5 that is grounded to the valley side portion SL ′ of the slope SL according to the above, and that is integrated with the bearing plate 4 has an angle α formed with the anchor body 1 by screwing the eyebolt 17 and the nut 20. Fixed. Therefore, as shown in FIG. 11, the connection point A between the pressure support plate 4 and the anchor body 1, the lower end C of the anchor body 1, and the valley-side tip B of the pressure support plate 4 mechanically form a triangle while forming an inclination angle. The suspension rope RP descends substantially parallel to θ to support the load.

くことができる。Therefore, the tilting moment with the lower end C of the anchor body 1 as a fulcrum due to the load is the slope SL of the bearing plate 4.
Even if the anchor body 1 is canceled by a pressing force (resistive force) against the anchor body 1 and is vertically inserted in the slope, the anchor body 1 can reliably and stably support the load. In other words, the sinking force on the anchor is suppressed,
This prevents the anchor body from collapsing.
Since the pressure support plate 4 is provided so as to be suspended from the tip end region of the arm portion 5, the resistance force is increased by the action of the lever, and therefore the size of the pressure support plate 4 should be relatively small. You can For example, if the anchor main body 1 supports a suspension fence load of about 4 tons, the pressure bearing plate 4 should be 0.2
A size of about 5 m 2 is sufficient. Since the angle change of the arm 5 is prevented by the fastening of the eyebolt 17 and the nut 20, the bearing plate 4 can be surely grounded to the slope SL '.
