中空パイプを埋設している。(Prior Art) Conventionally, in this type of anchor, an opening/closing vane is attached below a hollow pipe, and the opening/closing vane is opened and closed by the expansion and contraction of a coil spring loaded just above the opening/closing vane. A string is attached to the lower end of the coil spring, and the upper end of this string is led out to the ground. In the case of the conventional example, the opening/closing blade is folded and put into an underground hole, and the coil spring is expanded deep underground to expand the opening/closing blade. At this time, the length of the string pulled in by the expansion of the coil spring is This allows the degree of expansion of the coil spring, and ultimately the expansion status of the opening/closing blades, to be visually confirmed from the ground. In addition, in the case of the conventional example, after the opening/closing blades are expanded, the fixing liquid is injected into the expanded underground hole through a hollow pipe and solidified, and the opening/closing blades, coil springs,
A hollow pipe is buried.

まうため、経済的損失も大きい。(Problems to be solved by the invention) According to the conventional example, it is difficult to correctly insert an anchor with a string into a deep and limited underground hole, and in order to expand the opening/closing blade, a hollow pipe is required. Since the cord is rotated with the coil spring, the cord becomes entangled with the hollow pipe, and the cord cannot be retracted to correspond to the expansion of the coil spring, making it impossible to accurately visually check the expansion status of the opening and closing blades. Furthermore, since the connecting material for tightening or tensioning is a hollow pipe, the cross-sectional area is small and the strength is low.In particular, the connecting material needs to be added and formed, and hollow pipes have a small wall thickness and need to be threaded. Since a joint is formed by using the pipe, the strength is extremely low, and moreover, expensive hollow pipes and coil springs are buried, resulting in a large economic loss.

角度が大となつていく。(Usage and operation of the embodiment) As shown in the first diagram, an underground hole 30 having approximately the same diameter as the serrated cylinder 18 is bored. Then, the opening/closing blade 7 is inserted in a folded state into the underground hole 30, and the serrated cylinder 18 is inserted into the hole bottom 30'. Furthermore, hollow pipe 5,
Rods 8 are added according to the depth of the underground hole 30,
It is something that forms. Subsequently, the hollow pipe 5 is connected to the rotary machine 31 via the small diameter portion 20a of the cap 20. At this time, coil spring 1
0 is visible from the ground, followed by hook 2 of string 23.
4 and 24, and remove the strings 23 and 23. Since the cap 20 is fixed above the coil spring 10, the coil spring 10 begins to extend downward, lowering the push pipe 9, and as the push pipe 9 descends, the elevator pipe 6 descends. When the elevator pipe 6 descends, the opening/closing blade 7
begins to expand as shown by the chain line in Figures 1 and 3. However, since each opening/closing blade 7 hits the peripheral wall of the underground hole 30, it does not fully open immediately. For this reason, immediately after the strings 23, 23 are removed from the coil spring 10, the rotary machine 31 is driven to rotate the hollow pipes 5, 3. When the hollow pipe 5 rotates, the connected hollow pipe 3
It also rotates. At this time, the hollow pipe 5 is
Therefore, it will not spiral any further. Since the plates 14, 14 are welded to the lower part of the hollow pipe 3, the opening/closing blade 7 rotates in the horizontal direction, gradually cutting the peripheral wall of the underground hole 30, and keeping pace with the progress of cutting. As a result, the widening angle of the opening/closing blades 7, 7, . . . increases.
このとき、地上ではコイルスプリング１０の伸
長状況を視認かつ計測して開閉羽根７の拡幅角度
を知ることができる。 At this time, the expansion angle of the opening/closing blade 7 can be known by visually observing and measuring the expansion status of the coil spring 10 on the ground.

個所の土壌を崩壊若しくは軟弱にして開閉羽根７
の回転を容易にして切削を進行させる。 Also, as the hollow pipes 5, 3 rotate, pressurized mud water is sent into the hollow pipe 5, and the pressure mud water is jetted vigorously from the holes 2, 2... of the hollow pipe 3, thereby collapsing or softening the soil at the cutting location. Opening/closing blade 7
The cutting progresses by making the rotation easier.

0' is a substantially semicircular cavity (as shown by the chain line in FIG. 1).
Here, the hollow pipes 5, 3 are further pulled up and lowered many times, and the semicircular ceiling is cut by the opening/closing blades 7, 7, . . . to form a horizontal ceiling as shown in the second figure.

イプ５，３の回動は続行させておく。 Next, the pressure mud water supply is stopped, and the hollow pipe 5,
Inject fixative liquid such as cement milk, cement mortar or concrete through 3.
Since the fixative liquid is heavier than the muddy water (for example, the specific gravity of cement milk is 1.9 to 2.1, while muddy water is 1.3), the muddy water rises to the surface and is pushed up to the ground.
The muddy water is replaced by a fixative solution. At this time, the rotation of the hollow pipes 5 and 3 is continued.

1, 22, and 22, the coil spring 10 and push tube 9 are also pulled up and recovered together with the hollow pipe 5. As a result, only the hollow pipe 3, opening/closing spring 7, and rod 8 are buried. After pulling up and collecting the above-mentioned parts, 30
It is only necessary to insert the aggregate into the underground hole 30 within minutes, after which the anchoring device is formed in the earth by solidification of the fixative liquid and the rod 8 projects into the ground.

Jacket 3 was added and installed on the structural frame 33.

The protruding part of the rod 8 is passed through the foundation 35 and the structural member 36 shown in chain lines, and is tightened with the nut 28 via the washer 29. The anchor of the present invention is not limited to the above, but can be used as a variety of anchors such as earth retaining, mountain retaining, vibration prevention of machine stands, etc. In addition to being installed vertically as described above, it can also be installed laterally or horizontally depending on the object. It may also be installed diagonally.

も大きい。(Effects of the Invention) According to the present invention, the coil spring can be immediately seen from the ground, and by measuring the degree of extension of the coil spring, the expansion status of the opening/closing blades can be accurately known. Since it is a rod, the cross-sectional area is larger than that of a hollow pipe.
It has great strength, and it also has great economic effects because hollow pipes, coil springs, and push pipes can be pulled up and recovered.
