METHOD FOR INSERTING CORE MATERIAL INTO ELECTRIC POLE
PROBLEM TO BE SOLVED: To solve a problem of a conventional method for inserting a core material into an electric pole such that the core material cannot be inserted into an electric pole at a predetermined height or higher because of a lift of a crane.SOLUTION: A method for inserting a core material into an electric pole according to the present invention comprises: suspending the core material 4 by a crane 7; inserting the core material 4 into the electric pole 2 from an upper end of the electric pole 2; after lowering the core material 4 to a desired height, interposing a long-sized member 12 between the crane 7 and core material 4; and further moving the core material 4 down.SELECTED DRAWING: Figure 1
【課題】従来の電柱内への芯材挿入工法は、クレーンの揚程から、所定の高さ以上の電柱には、芯材を挿入することができないという問題点があった。【解決手段】本発明の電柱内への芯材挿入工法は、クレーン７により、芯材４を吊下げ、該芯材４を電柱２の上端から電柱２内に挿入し、該芯材４を所望の高さまで下降させた後に、上記クレーン７と上記芯材４との間に長尺部材１２を介在させて、更に、芯材４を下方に降下させることを特徴とする。【選択図】 図１
