  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention (hereinafter referred to as embodiments) will be described with reference to the drawings.

  FIG. 1 is a front view showing an embodiment of a hollow column of the present invention. 2 shows the hollow column 1 shown in FIG. 1, the reinforcing portion 10 of the hollow column disposed in the cavity 5 of the hollow column 1, and the flexible conduit for guiding the cable member S such as an electric wire or a communication line. 3 is a perspective view showing a material 11. FIG.

  The hollow pillar 1 shown in FIG. 1 is a steel pipe pillar without a taper, for example. However, the hollow pillar of the present invention is not limited to this, and includes a steel pipe pillar having a taper and a concrete pillar (for example, a concrete power pole having a taper or a concrete power pole having no taper).

  In FIG. 1, illustration of the upper part of the hollow column 1 is omitted. A lower portion of a predetermined length from the base end portion 2 of the hollow column 1 is embedded and standing as an underground portion 3, and the remaining portion of the hollow column 1 appears on the ground as a ground portion 4. The base end 2 of the hollow column 1 is closed.

  As shown in FIGS. 1 and 2, the internal structure of the hollow column 1 has a hollow 5 having an inner diameter that is constant along the length direction, and is a hollow cylindrical body.
