Abstract

(57) [Summary] [Purpose] To provide a boundary pile whose position can be easily confirmed with a metal detector even when the boundary pile is buried in the soil and cannot be seen. [Structure] A pile body 1 made of a synthetic resin member or a concrete member is provided with a metal member made of metal powder or metal pieces 2. Alternatively, the metal member may be configured in a tubular shape 3 for accommodating the pile body 1 or in a cap shape 4 or a rod shape 5 provided on the top or inside of the pile body 1.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a boundary pile including a metal member whose position can be easily confirmed with a metal detector even when buried in the soil.

[0002]

[Prior art and its problems]

 Boundary piles used to determine the boundaries of land are often buried in the soil after many years have passed since they were driven in during surveys such as national land surveys. It becomes difficult to confirm the above, and there are many cases in which there are doubts about the boundary between the landowners and their related parties.

[0003] Therefore, if necessary, it may be necessary to carry out surveying again based on a public chart to determine the boundaries, which is costly and troublesome, and reliability of surveying is often impaired. .

[0004]

[Purpose and structure of device]

 The present invention provides a boundary pile designed so that its position can be easily confirmed with a metal detector even when the boundary pile is buried in the soil and cannot be visually recognized.

Therefore, the boundary pile of the present invention is basically constructed such that the pile main body formed of a synthetic resin member or a concrete member is provided with a metal member. When such a metal member is a metal powder or a metal piece, this metal member can be mixed into the pile body.

The metal member as described above may be formed in a tubular shape so as to accommodate the pile body, or may be formed in a cap shape or a rod shape provided on the top or inside of the pile body.

【Example】

 FIG. 1 is a conceptual cross-sectional view of a boundary pile constructed according to an embodiment of the present invention, in which the pile body 1 is made of a suitable synthetic resin member or concrete member so as to have a prescribed size. It can be formed into a cylindrical or prismatic shape. In this embodiment, when the pile main body 1 is formed, an appropriate amount of a metal member made of metal powder or metal pieces 2 is mixed with the material of the pile main body 1 to integrally form it.

Appropriate plastic waste can be reused for the synthetic resin member used as the material of the pile body 1, and the metal powder or the metal piece 2 can be reused as a whole by using various kinds of metal waste. Can be configured as an inexpensive boundary pile. With a boundary pile having such a metal member, even if the boundary pile is buried in the soil, its position can be easily and surely confirmed with a small and inexpensive metal detector. Therefore, the boundary confirmation can be processed promptly.

As a method for providing the pile main body 1 with the metal member, a metal pipe 3 for accommodating most or all of the pile main body 1 can be used as shown in FIG. As shown in FIGS. 3 and 4, a structure in which a metal cap 4 is attached to the top of the pile body 1 or a metal rod 5 is embedded inside can also be adopted. When the metal tube 3 or the metal cap 4 is used, it is preferable to use a corrosive metal as a material thereof so as to improve durability.

[Effect of the device]

 According to the boundary pile of the present invention, it is easy to configure a part of the boundary pile to be equipped with a metal member. Therefore, after the boundary survey is fixed using this boundary pile, the fixed boundary pile is not Even in the buried state, the position can be easily and surely detected by the metal detector to promptly confirm the boundary.

[0011] Therefore, it is possible to eliminate the duplication of the surveying and the labor involved in the unclear boundary pile, and to secure the reliability of the boundary that conforms to the official map.

The boundary pile of the present invention can be provided at low cost, and it is sufficient that the metal detector used for detecting the boundary pile is small and inexpensive.
