Assembled utility pole, pole building method and rebuilding method

Abstract

An object of the present invention is to provide a utility pole and a method for constructing the utility pole, which can simplify and improve efficiency of work at the time of new construction and replacement and can shorten a work period.The anchor has a larger diameter than a body of a utility pole on the ground and has higher ground support force. Thus, the hole for building the assembly type utility pole on the ground can be made shallower than the hole for building the utility pole in related art on the ground. The depth of the hole is shallow, so that it is possible to reduce a period for digging, reduce a probability of hitting a buried object, and reduce work for confirming a buried object. In addition, the assembly type utility pole includes a plurality of parts, and thus, only a degraded portion needs to be replaced, so that it is possible to shorten replacement work. Further, the assembly type utility pole includes a plurality of parts, and thus, each part is smaller than that of the utility pole in related art, so that it is possible to simplify work.

1 . An assembly type utility pole comprising:
 a pole; and   an anchor that is a substantially cylindrical object having a diameter larger than a diameter of the pole and has a hole into which one end of the pole is fitted,   wherein the pole and the anchor become coaxial when the one end of the pole is fitted into the hole of the anchor.   
     
     
         2 . The assembly type utility pole according to  claim 1 , wherein the anchor has an earth auger on a surface thereof. 
     
     
         3 . The assembly type utility pole according to  claim 1 , wherein the pole can be divided into at least two portions in a longitudinal direction. 
     
     
         4 . The assembly type utility pole according to  claim 1 , further comprising:
 a lock member that fills a gap between the pole and the hole, the gap being generated when the one end of the pole is fitted into the hole of the anchor.   
     
     
         5 . A method for constructing a utility pole, comprising:
 burying an anchor of a substantially cylindrical object having a diameter larger than a diameter of a pole in a ground such that one end of a bottom surface of the substantially cylindrical object substantially matches a ground surface; and   fitting one end of the pole into a hole of the anchor in which the pole and the anchor are coaxial.   
     
     
         6 . The method for constructing the utility pole according to  claim 5 , wherein when the anchor is buried in the ground, the anchor is rotated in an axial direction, and the ground is dug with an earth auger installed on a surface of the anchor. 
     
     
         7 . The method for constructing the utility pole according to  claim 5 , wherein when the pole is divided into two or more portions in the longitudinal direction, stacking another divided pole on the other end of the pole after one end of the pole is fitted into the hole. 
     
     
         8 . A method for replacing an assembly type utility pole that comprises:
 a pole that can be divided into two or more portions in a longitudinal direction;   an anchor that is a substantially cylindrical object having a diameter larger than a diameter of the pole and is buried in a ground such that one end of a bottom surface of the substantially cylindrical object substantially matches a ground surface,   in which one end of the pole is fitted into a hole of the anchor in which the pole and the anchor are coaxial, the method comprising:   dividing the pole;   lifting up an upper portion of the divided pole;   removing a lower portion of the divided pole from the anchor;   fitting one end of a lower portion of a new pole into the hole of the anchor; and   connecting one end of an upper portion of the pole that is being lifted to the other end of the lower portion of the new pole.
