DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a pile with a retaining anchor according to the present invention will be described below with reference to the drawings. In FIG. 1, a pile 1 with a retaining anchor is provided with an anchor blade 4 rotatably via a shaft 5 on the tip 3 side of the rod 2 which is driven into the ground. A ring portion 6 is attached to the rear end portion of the rod-shaped body 2 via a bolt 7 and a nut 8 so as to be rotatable to both sides beyond the rear end portion of the rod-shaped body 2. A pull-out jig 9 is provided at a substantially central portion of the rod-shaped body 2. The pull-out jig 9 is configured to be able to slide through the ring portion 6.

In FIG. 1, the anchor blade 4 is closed along the rod-shaped body 2, the ring portion 6 stands in a vertical position, and the extraction jig 9 is used.
Indicates a state in which the rod-shaped body 2 is mounted substantially at the center.

At the time of driving the retaining anchored pile 1, as shown in FIG. 1, the retaining anchored pile 1 is driven in a state where the anchor blades 4 are closed along the rod-shaped body 2.
As the rod-shaped body 2 is driven, the anchor blade 4 is driven into the soil to a proper depth while receiving a force applied to the pressed portion along the rod-shaped body 2 by the rear bent portion 4a of the anchor blade 4.

Further, the drawing jig 9 shown in FIG.
Has a structure in which an anchor blade opening prevention cap portion 9a having an opening large enough to surround the closed anchor blade 4 and an opening portion through which the rod-shaped body 2 penetrates are connected by a surface.

Next, when pulling out the pile 1 with pull-out anchors that has been driven in, first, the pile 1 with pull-out anchors is driven until the anchor blades 4 are closed. At this time, the anchor blades 4 are closed as in the case shown in FIG.

When the anchor blade 4 is in the closed state, the extraction blade 99 shown in FIG. 1 is passed through the rod-shaped body 2 from the anchor blade opening prevention cap portion 9a side to the outside of the anchor blade 4 in the soil. Drive into the position where the opening prevention cap portion 9a is hooked. Subsequently, when the anchor jig 4 is pulled out at the same time as the anchoring pile 1 with the pulling jig 9 attached, the anchor blade 4 is not pressed by the anchor blade opening prevention cap portion 9a but spreads smoothly and can be pulled out from the soil.

The pull-out jig 9 may be driven into the rod-shaped body 2 in the assembled state, or may be removed at all times and may be assembled and used only during the pulling-out operation.

FIG. 2 shows a state in which the anchor blade 4 is opened at an acute angle with respect to the rod-shaped body 2. That is, the rod-shaped body 2 is pulled back in the place where it is driven to an appropriate depth, at this time, the bent portion 4a at the rear end portion of the anchor blade 4 hooks the soil,
Since the rod-shaped body 2 is pulled back and moves in the direction of pulling it out of the soil, the anchor blades 4 open as it moves. Anchor feather 4
Via the shaft 5 is rotated to a position where the semi-arc cutout 4b of the anchor blade 4 and the rod-shaped body 2 come into contact with each other to stop the spread.

In this state, the anchor blades 4 are sufficiently resisted by the soil, so that the anchor blades 4 will not come out even by the tension of the connecting line 15. It is possible to penetrate the rod-shaped member 11 by placing the ring portion 6 at the rear end portion of the rod-shaped body 2 of the pile 1 with the anchors anchored at an appropriate height at an appropriate interval so that the ring portion 6 is located at the upper end of the rod-shaped body 2. .

3 (a) and 3 (b) show another embodiment of the ring portion 6, each of which has an opening at the rear end in the direction perpendicular to the longitudinal direction of the rod-shaped body 2. 2 is mounted at a position slightly apart from the rear end face of FIG.
3B shows a bar-shaped member 2 obtained by bending a bar-shaped member, and FIG. 3B shows a bar-shaped member 2 formed by annularly forming the bar-shaped member or slicing a pipe into the bar-shaped member 2 by welding or the like.

In this embodiment, the ring portions 6a and 6b are located slightly apart from the rear end surface of the rod-like body 2 when the retaining anchored pile 1 is driven by a hammer or the like, so that the ring portions 6a and 6b may be damaged. At the same time, it has a simple structure and can be manufactured at low cost.

FIG. 4 is a front view of the pile 1 with the retaining anchors. Anchor blade 4 for the effect of anchoring anchor
Have an appropriate width (W).

FIG. 5 is a perspective view of the anchor blade. The anchor blade 4 has a substantially trapezoidal shape, and a semi-arc notch 4b is provided at the substantially center of the front end portion. A bent portion 4a is provided in a direction away from the bent portion 4a. The anchor blade 4 is provided with two substantially trapezoidal rib portions 4c at positions sandwiching the rod-shaped body 2 by welding or the like so that a hinge hole 4d is penetrated through the mounting rib 4c and the rod-shaped body 2 and the shaft 5 and the like can be rotated. I'm trying to assemble it.

FIG. 6 shows an embodiment in which the greenhouse 10 is connected by the piles 1 with the anchors for anchoring.

The ring portion 6 provided at the rear end of the rod-shaped body 2 of the pile 1 with the anchors anchored around the vinyl house 10 has the height and direction aligned with each other, and the rod-shaped member 11 is passed through the tether to hold the vinyl house 10. The figure shows a state in which 15 cables are crossed over the required number of vinyl houses 10 to be knotted.

[0029]

Since the present invention is constructed as described above, it has the following effects.

The anchor blade attached to the rod-shaped body is driven in a closed state along the rod-shaped body, and when the rod-shaped body is pulled back in the direction of pulling out, the anchor blade opens at an acute angle with respect to the rod-shaped body and the soil resistance is increased. It does not come out, and it becomes a so-called anchor state.

This is the same as the conventional vertical pile in which the horizontal pile is assembled and embedded in the ground. The pull-out anchored pile has a strong pulling-out force, so that the number of pull-out anchored piles is much smaller than that of the conventional pile. can do.

Further, since the rod-shaped member entirely penetrates the ring portion of the rod-shaped member, it can be tied to the most preferable position anywhere.

Further, after the use, the expansion of the anchor blade can be suppressed by the anchor blade opening prevention cap portion of the extraction jig, so that the pile with the anchoring anchor can be smoothly extracted.
