PURPOSE:To prevent the settlement of electric pole by a method in which a supporter having a sufficient pressure-resisting area is constructed at the deepest portion an electric pole-erecting hole excavated by earth auger and an electric pole is erected on the supporter. CONSTITUTION:The first base plate A is inserted into the bottom of a hole excavated by a earth auger, and the first and second resistance plates 2 and 3 of the base plate A are pressed into holes of walls, drilled by two rotary angle pipes 12 in respective opposite directions on a line connecting with the center of the base plate 1. Then, under the guidance of the rotary angle pipe 12, the second base plate B is inserted and the third and fourth resistance plates 15 and 16 of the base plate B are pressed into the holes of the wall, drilled by the rotary angle pipe 12 in respective opposite directions on a line crossing at a right angle to the line in the opening directions of the first and second resistance plates 2 and 3. Then, under the guidance of the rotary angle pipe 12, a reinforcing base plate C is inserted, a regulating bar 11 and 4 rotary angle pipes 12 are removed, an electric pole is soon erected, and the reinforcing base plate C is expansively set on the resistance plate expanded toward four directions under the weight of the electric pole. |
