Title:
METHOD FOR CONSTRUCTING UTILITY POLE FOR ELECTRIC LINE WITH HIGH STRENGTH USING EXTENDABLE EXCAVATING UNIT AND ROOT UNDERBRACING
Document Type and Number:
WIPO Patent Application WO/2011/132980
Kind Code:
A2
Abstract:
The present invention relates to a method for constructing a utility pole for an electric line to be penetrated with high strength, and more specifically, to a method in which: an easy excavation for the penetrated portion of a utility pole is performed by using an extendable excavating unit mounted on an auger crane, and at the same time, a separate root underbracing is mounted on the lower end of a laying unit of a utility pole; the existing utility pole underbracing is mounted with said root underbracing, wherein said utility pole underbracing is fixedly installed in a direction matched with a tensile direction acting on the utility pole, and said root underbracing is fixedly installed on an opposite side to the tensile direction acting on the utility pole, so that strong bearing power for the utility pole to which tension is applied can be given by said utility pole underbracing and said root underbracing, thereby maximizing the performance of high-strength and super high-strength utility poles; and in the case of a utility pole that needs high-strength vertical bearing power by being equipped with a heavy apparatus, or in the case of a utility pole which has weak underground bearing power or needs to reinforce ground bearing power owing to an applied strong tensile force, such as a utility pole that crosses poor ground or an angular place or a railroad or a high-level road, and a river or the like, strong vertical bearing power for the utility pole is given by the existing utility pole underbracing and the root underbracing coupled with the lower end of the laying unit of the utility pole, thereby preventing, at low investment costs, said utility pole from being inclined or falling down in a tensile direction, and further magnifying the performance of high-strength and super high-strength utility poles whereby high-quality power facilities for high-capacity power supply can be sturdily constructed.
