The present invention relates to a method for constructing a high strength electric pole by using concrete placement when the electric pole is constructed by using an expanding excavator of an auger crane. More specifically, one electric pole insertion hole and a reversed T-shaped excavation unit inside the electric pole are formed when the electric pole insertion hole is formed in order to embed the electric pole. High early strength concrete is placed in an expanding excavation unit, and the electric pole is supported by a concrete foundation structure of the reverse T-shaped excavation unit. The present invention obtains a strong vertical support force equally applied to the outer circumference of the electric pole without the installation of additional support unit of the electric pole. An excavation screw for the auger crane can remarkably improve support strength and workability of electric pole construction with a simple process by simplifying excavation work. |
