  However, in the said structure, since an identification body must be accommodated in the head of a pile main body before putting a cap, workability | operativity is bad. Moreover, in order to prevent that an identification body is taken out by mischief, the special structure which prevents a cap from being removed from the head of a pile main body is required.

  An object of the present invention is to provide a marking pile to which an identification body can be attached by a simple method.

In order to achieve the above object, the marking pile according to the present invention is a marking pile embedded in the ground such that at least a part of the head is exposed from the ground surface, and is inserted into the insertion hole formed on the top surface. A nail-shaped fastening member having an identification body for transmitting stored information when receiving a read electromagnetic wave is inserted by driving .

  According to the said structure, since the said identification body is a nail shape, it can be easily attached to a marking pile only by lightly driving it in the insertion hole opened in the top face of the marking pile. Moreover, since an identification body can be attached to the marked pile in the embedded state, workability is good. Furthermore, when the identification body is not attached, a pole or a light wave reflecting mirror, which is a surveying instrument, can be set up in the insertion hole, so that it can also be used for surveying. Moreover, since it is only necessary to add an insertion hole to the marking pile, the present invention can be easily applied by providing the insertion hole by drilling in the existing marking pile.

  Moreover, in preferable embodiment of this invention, it is an indication pile by which a cap is put on the head of a pile main body, Comprising: The said insertion hole is formed in the said cap.

  Furthermore, in a preferred embodiment of the present invention, a display plate for identifying the marking pile is fixed to the head of the marking pile by the fixing member. According to this structure, it is not necessary to provide another attachment member in order to attach the display plate to the marking pile.

  According to the marking pile provided with the discriminating body of the present invention, the discriminating body can be easily attached to the marking pile.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. A marking pile A shown in FIG. 1 is formed by forming a distal end portion 11 on the distal end side of a pile body 1 having an elongated cross-sectional star shape and a head portion 10 having a quadrangular prism shape on the other side. Further, a cap 12 that covers the top surface 10a and the side surface 10b is attached. The cross-sectional shapes of the pile main body 1 and the cap 12 can be various shapes such as a triangle, a quadrilateral or more polygon, and a circle. Further, an insertion hole 13 is provided in the top surface 12 a of the cap 12. In addition, the material of the said pile main body 1 and the cap 12 is formed with the recycled resin which uses the resin waste generated at the time of shaping | molding of a resin product, the waste of a resin product, etc. as a raw material.

  The insertion hole 13 extends along the longitudinal direction of the pile body 1, and as shown in FIG. 2, a guide surface 13 a that extends outward is formed at the entrance. The insertion hole 13 is attached with a nail-shaped fastening member 15 that incorporates a cylindrical or polygonal columnar identification body 2 that transmits stored information when receiving an electromagnetic wave for reading from outside. As the material of the fastening member, a metal such as ceramics, aluminum or stainless steel is used in addition to the resin. The inner diameter of the insertion hole 13 is set to be slightly smaller than the outer diameter of the fastening member 15, and the fastening member 15 is inserted into the insertion hole 13 by lightly striking the insertion hole 13 with, for example, a hammer, Fixed. Since the guide insertion hole 13 is provided, it is not necessary to strongly drive the fastening member 15, so that there is no possibility of information being destroyed by the driving hit. Moreover, even if it is the resin fastening member 15, it will become difficult to break when driving.

  The discriminator 2 is formed by appropriately arranging a resonance substance and a magnetic material, or by appropriately mixing both, and using a magnetic resonance phenomenon when a magnetic field is added thereto, a specific frequency (resonance) is formed. Frequency) electromagnetic waves. The electromagnetic wave having this specific frequency is information indicating the identification number of the pile, for example.

  The addition of the specific frequency (information) to the discriminator 2 is performed by discriminating an electromagnetic beam, a particle beam, or the like that can change the resonance characteristics of the discriminator 2 chemically, crystallographically, or physically as in a known technique. Done by firing on the body 2. Since the information added to the identification body 2 in this way may be destroyed when a strong impact is applied, the information is sent to the fastening member 15 after the fastening member 15 is driven into the head 10 of the pile body 1. It is preferable to add.

  However, it is also possible to drive the fastening member 15 into the marking pile A after adding the identification information to the identification body 2. However, in this case, it is preferable to make the insertion hole 13 of the cap 12 slightly larger and attach the fastening member 15 without driving it in strongly.

  In addition, as shown in FIG. 3, when the identification body 2 is not attached, for example, a pole 16 that is a surveying instrument having a length of about 20 to 30 cm is set up in the insertion hole 13 as a marker for optical surveying. Can be used. At this time, the pole 16 is smoothly inserted into the insertion hole 13 by the guide surface 13a. Further, as a surveying instrument, in addition to the pole, a light wave reflecting mirror for reflecting the light wave from the surveying light wave emitter toward the light wave emitter may be provided.

  In the above configuration, after the marking pile A is driven into the ground C, the fastening member 15 is attached to the marking pile A. At this time, since the identification body 2 has a nail shape, it can be easily attached to the marking pile A simply by lightly driving it into the insertion hole 13 formed in the top surface 12a of the marking pile A. Moreover, since the identification body 2 can be attached to the marking pile A in an embedded state, workability is good. Furthermore, when the identification body 2 is not attached, a pole 16 or a light wave reflecting mirror, which is a surveying instrument, can be set up in the insertion hole 13, so that it can also be used for surveying. Moreover, since only the insertion hole 13 needs to be added to the marking pile A, the present invention can be easily applied by providing the insertion hole 13 in the existing marking pile A by drilling.

  Further, a display plate 20 for identifying the marking pile A may be attached to the head of the marking pile A using the nail-shaped fastening member 15. As shown in FIG. 4, the display plate 20 is provided with an insertion hole 13 in which a guide surface 13 a that extends outward is formed on the top surface 12 a of the cap 12, and the nail-shaped fastening member 15. Is inserted into the insertion hole 21 provided in the center of the display plate 20 and driven into the insertion hole 13 to be attached to the marking pile A. The display plate 20 is made of a metal or resin having corrosion resistance such as aluminum and stainless steel, and can have any shape such as a circle or a polygon, but usually has a circular shape as shown in FIG. A plate is preferably used. On the surface of the display plate 20, various information such as the identification number of the marking pile A, the use of the marking pile A, the boundary display and division number of the land, the distance from the reference point, and the information of the underground buried object are printed or printed. be able to. In the case of the present embodiment, characters of “land ownership survey” are printed and the identification number “3030” of the marking pile A is engraved. According to this configuration, it is not necessary to provide another mounting member for mounting the display plate 20 to the marking pile A.

  Furthermore, as shown in FIG. 5, in the case of the marking pile A without the cap 12, the head of the pile main body 1 is provided with an insertion hole 14 in which a guide surface 14 a that extends outward is formed at the entrance portion, The inner diameter of the insertion hole 14 is set slightly smaller than the outer diameter of the fastening member 15, and the fastening member 15 is directly driven into the insertion hole 14 of the pile body 1 and inserted. In this case, the display plate 20 shown in FIG.
