<p>The present invention discloses a method for constructing an arch-type utility pole underbracing using extendable excavating unit for auger crane. The present invention provides a method for constructing an arch-type utility pole underbracing after getting an idea from the construction method of rectangular utility pole underbracing as described above. It is an object of the present invention to provide a method for constructing arch-type utility pole underbracing for overhead line using extendable excavating unit for auger crane, whereby work efficiency is improved because it is possible to perform the excavation process easily by carrying out 2-step bench cut by extension and reduction of an auger crane extendable excavating unit without extra additional man power or complicated additional processes, and also it is possible to bury the utility pole and arch-type utility pole underbracing firmly with a small amount of earth also during refilling work.</p> |
