  However, since the surveying nail is driven into the wooden pile as described above, the one used once cannot be reused and becomes disposable. For this reason, used wooden piles are often disposed of, which is disadvantageous in terms of economy and environment.

  This invention is made | formed in view of this subject, It can be reused or can also be used as this pile, and it aims at providing the temporary pile for a marking excellent economically and environmentally. .

In order to achieve the above-described object, the invention described in claim 1 is a temporary pile for marking that is driven into the ground before setting the main pile and represents a boundary point or a survey point.
The pile main body and the head are made of plastic, and a large number of small holes into which surveying nails can be driven are formed on the top surface of the head.

  In the invention according to claim 2, the top surface of the head according to claim 1 is further provided with a receiving hole for receiving a projection provided on the marking cap with the marking content for the main pile. It is characterized by a marking temporary pile that can become a main pile by being attached to the head.

  The invention according to claim 3 can be attached to the head according to claim 2 and has a surface with a pattern such as a figure, a character, a symbol, or a color representing the contents of marking, and the receiving hole on the back surface. It features a marking cap for making a temporary pile for marking formed with a projection that can be inserted into the main pile.

  According to the present invention, a boundary point or a survey point can be represented by selecting one of a number of small holes formed on the top surface of the head of the display temporary pile and driving a surveying nail. By using a small hole as a guide for driving a surveying nail, even if the temporary pile is made of plastic, the surveying nail can be easily driven, and the top surface of the head will not be destroyed. If the surveying nail is removed, the temporary pile can be used again. Since temporary piles are made of plastic, they are durable and can be used over and over again.

  According to invention of Claim 2 or 3, a temporary pile can also be used as a main pile as it is by attaching a marking cap to a head. By selecting and attaching a marking cap with appropriate marking contents, it is possible to adapt to the scene in a flexible manner. Because it is made of plastic, it can withstand long-term use as a main pile.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a temporary pile 10 according to an embodiment of the present invention, which is configured as an integral plastic as a whole, roughly, a pile body 13 having a leading portion 12 on the lower side, and a head portion on the upper side. 14. The temporary pile 10 can be made of any single material such as polyethylene, polypropylene, polyester, polycarbonate, or a plastic made of a composite material, and can be formed by injection molding, blow molding, or the like. If the pile main body 13 and the head 14 are integrally molded, it can be manufactured at low cost, which is preferable.

  The leading portion 12 is preferably sharp at the tip so that it can be easily embedded in the ground. Furthermore, the pile main body 13 has a cross shape with a continuous cross-sectional shape, and maintains rigidity. However, the present invention is not limited to this, and the cross-sectional shape of the temporary body 13 can be any shape such as an H shape, a pyramid, a prism, a cone, or a cylinder.

  The head 14 has a larger cross-sectional shape than the pile body 13. In this example, the cross-sectional shape of the head is a quadrangle. However, the shape is not limited to this, and any shape such as a circle, a triangle, or a polygon can be used. Moreover, the inside of the head 14 is good to be a cavity.

  Further, as shown in FIG. 2, a large number of small holes 14 a are formed in the top surface of the head 14. The inner diameter of the small hole 14a is preferably smaller than the outer diameter of the commercially available surveying nail 16, for example, about 1 to 3 mm.

  The temporary pile 10 configured as described above is driven into a predetermined location from the leading portion 12 and is buried at an appropriate height. Next, when surveying is performed and a boundary point or survey point is determined, a survey nail 16 is driven into the small hole 14a located at a position corresponding to the point (see FIG. 3).

  Since many small holes 14a are formed, a point can be specified by selecting one of the small holes 14a. In addition, since it is driven into the small hole 14a, it can be driven into the head 14 of the temporary pile 10 without damaging the surveying nail 16 and the head 14. The surveying nail 16 is pushed into the small hole 14a while expanding the small hole 14a using the elasticity of the plastic of the temporary pile 10, and can be easily removed once it is driven into the small hole 14a. Absent.

  After the use of the temporary pile 10 after being refilled with the main pile, when the surveying nail 16 is removed from the small hole 14a, the small hole 14a can be almost restored to its original state by elasticity. The pile 10 can be used any number of times. Moreover, since the temporary pile 10 is made of plastic and has excellent durability, it can be used repeatedly. Since the temporary pile 10 is not disposable, it is preferable in terms of environment and economy.

  FIG. 4 is a diagram showing a second embodiment of the present invention, and the same parts as those in the first embodiment are denoted by the same reference numerals and the description thereof is omitted. The temporary pile in this example can be used as a main pile in addition to having a function as an original temporary pile.

  That is, as shown in FIG. 5, a plurality of small holes 14 a are formed in the head 14 of the temporary pile 10 of this example, and a plurality of receiving holes 14 b for the main pile cap for receiving the marking cap 18 are formed. Has been. About 2 to 4 receiving holes 14b may be formed, and the inner diameter thereof is set larger than the inner diameter of the small hole 14a.

  The marking cap 18 has an inner shape into which the head 14 can be fitted and can be attached to the head 14 from above. The marking cap 18 can also be made of plastic, like the temporary pile 10, and can be made of any plastic such as polyethylene, polypropylene, polyester, polycarbonate and the like. However, unlike the temporary pile 10, the marking cap 18 can be made of any material other than plastic (aluminum, stainless steel, brass, alloy, etc.), ceramics, or concrete.

  The top surface 18a of the marking cap 18 is provided with patterns such as figures, characters, symbols, and colors representing the marking contents as the main pile. As shown in FIG. 6, it is good to prepare in advance many types of marking caps 18 with various patterns according to the types of main piles that can be used.

  A plurality of protrusions 18b are formed on the back side corresponding to the top surface of the marking cap 18, and a plurality of locking steps 18c are formed on the side peripheral surface of the protrusion 18b.

  As described in the first embodiment, after being used as the temporary pile 10, when used as the main pile, the surveying nail 16 is attached to the head 14 of the temporary pile 10 or the surveying nail 16 is attached. The temporary pile 10 is driven into the ground as necessary to adjust the point, and then the temporary pile 10 is solidified. Next, the marking cap 18 indicating the adjusted point or the like is put on the head 14 of the temporary pile 10, and the projection 18b is inserted into the receiving hole 14b of the head 14 (see FIG. 8). Since the locking step 18c is locked to the receiving hole 14b, the protrusion 18b is not easily pulled out after being inserted into the receiving hole 14b, and the marking cap 18 and the temporary pile 10 are coupled inseparably. It functions as a main pile.

  Thus, since the temporary pile 10 is made of plastic and has durability, the temporary pile 10 can be sufficiently used as it is as the main pile, and the temporary pile 10 is not disposable, which is preferable in terms of environment and economy.
