Abstract

PURPOSE:To easily set a boundary pile even in narrow places without the needs for excavating pits in wide range by a method in which a rotary tool is attached to the head of the bounday pile, the pile is vertically set, and the axle of the pile is penetrated into the ground while being turned. CONSTITUTION:The tip of the axile 4 of a boiundary pile 1 is sharpened, the intermediate part of the pile is shaped into a round columnar form, and the periphery of the pile is provided with a spiral screw 5. A heat 3 having a label display 8 is provided to the upper end of the axile 4, and a boundary mark is formed on the upside. A recession 6a to be attached with the head 3 of the pile 1 detachably is provided for the cap 6 of a rotary tool 2, and rotary handles 7 are welded to both sides of the cap 6. The handles 7 are set at almost right angle to the axis of the pile 1 and inserted into the ground by striking it by a tool, and the handles 7 are horizontally turned. The axile 4 is buried to stop the rotation, and the cap 6 is removed from the head 3 to remove the rotary tool 2. The setting operation can thus be easily attained without causing any trouble with boundary movement as well as without the needs to break the ground.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is applicable to, for example, roads and private areas,
The present invention relates to a boundary pile (boundary mark) installed at a boundary between private land and a private land, and a rotating jig for rotating the boundary pile to penetrate into the ground.

[0002]

2. Description of the Related Art A conventional boundary pile, as shown in FIG.
A boundary pillar 11 made of reinforced concrete or plastic in the shape of a prism is used, a display portion 11b for writing characters is provided on the upper portion of the boundary pile 11, and a boundary symbol 11a is provided on the upper surface of the head as shown in FIG. Is engraved.

As the boundary pile 11, as shown in FIG. 9, there is a boundary pile having a substantially prismatic shape and the tip end thereof is sharpened so that it can be easily driven into the ground.

Further, when the boundary pile 11 is installed at a boundary place, as shown in FIG. 10, a scoop or the like is provided at a deep area where the display portion 11b is exposed from the ground at the site 9 where the ground or ground is filled and grounded. After digging the hole a, the boundary pile 11 is arranged vertically with the tip end thereof facing downward, and then the hole a is backfilled with the filling soil 10.

[0005]

However, in the above-mentioned conventional technique, even if the hole is struck with the boundary pile 11 in the dug hole and then the hole is tamped with earth and sand, the hole is still supported in a loose state. Therefore, it is in an unstable state, and the boundary pile 11 easily tilts and moves due to an unexpected impact or the like. Therefore, when the boundary pile tilts or moves and the boundary shifts, a boundary dispute occurs.

Further, since it is necessary to dig a large hole around the boundary pile 11 to some extent, it is extremely difficult to install it in a narrow place.

The present invention was devised in view of these problems, and an object thereof is to provide a boundary pile which can be installed in a narrow place without destroying the ground and a rotary jig for the boundary pile.

[0008]

In order to achieve the above object, in a boundary pile according to the present invention, the tip portion is formed in a sharpened shape, and a prismatic shape is formed at the upper end of the shaft portion engraved with a spiral screw on the outer periphery. It is configured to be integrated with the head of.

Further, the rotating jig for the boundary pile has a structure in which the rotary handles are integrally provided on both sides of a cap having a detachable recess in the head of the boundary pile.

[0010]

The boundary pile is installed by inserting a rotating jig or a rotating member on the head, rotating the boundary pile in a vertically arranged state, and screwing the shaft into the ground.

In addition, when the rotating jig of the present invention is used, after the tip of the boundary pile is placed vertically at the place where the boundary pile is installed, it is erected vertically, and then the rotating jig is attached to the head of the boundary pile. Fit the cap, tap the upper side of the cap lightly with a striking jig such as a kayak several times to penetrate the tip of the boundary pile into the ground, and rotate it horizontally with the rotating handle (see Figs. 5 and 6). .

When the shaft of the boundary pile is buried, the rotation is stopped, the cap is removed from the head and the rotating jig is removed, and the installation of the boundary pile is completed.

[0013]

1 to 6 showing an embodiment of the present invention.
The boundary pile 1 is made of reinforced concrete, synthetic resin, reinforced plastics, etc., and is composed of the shaft portion 4 and the head portion 3.

The shaft portion 4 is formed by sharpening the tip end into a sharpened shape, for example, a conical shape, the middle portion of the shaft portion 4 is formed into a cylindrical shape, and a spiral screw 5 is engraved on the outer periphery thereof. Has been done.

A prismatic head portion 3 is integrally provided on the upper end of the shaft portion 4, and a display portion 8 for writing a mark on the head portion 3 is formed.
Is provided, and a boundary symbol 3a or the like is engraved on the upper surface of the head 3.

The rotating jig 2 is made of metal or synthetic resin,
A jig for vertically inserting the boundary pile 1 into the ground in a screwed form, and the rotating jig 2 is composed of a cap 6 and a rotating handle 7, and the cap 6 can be attached to and detached from the head 3 of the boundary pile 1. The recess 6a that can be fitted to the cap 6 is provided.
Rotation handles 7 are integrally formed by welding or the like at positions substantially opposite to each other.

The handle 7 is formed in such a length that it can be easily rotated by human power, and is arranged in a direction substantially perpendicular to the axis of the boundary pile.

[0018]

Since the present invention is constructed as described above, it has the following effects. A spiral screw is engraved on the shaft part of the boundary pile, and the shaft part is rotated by a rotating jig to penetrate into the ground in a screwed form, so that the ground can be penetrated without being damaged or damaged. be able to.

In addition, since the periphery of the boundary pile is left as it is on the ground floor, the rotating handle is rotated to allow the shaft portion of the boundary pile to enter, so that the shaft portion is firmly fixed to the ground and is firmly fixed. Even if a shock or the like is applied, the boundary pile will tilt and will not move. Therefore, it is possible to prevent troubles caused by movement of boundaries.

Furthermore, since there is no need to dig a wide area around the boundary pile as in the conventional case, the installation work can be performed easily and easily.

Since the installation work can be carried out if there is a rotatable area of the rotary jig, it can be easily installed even in a narrow place.
