PROBLEM TO BE SOLVED: To prevent increase of ground area to be needed and to solve shortage of strength of a steel tower for a power-transmission line from the lower part to the upper part of the tower after piling against received power by wind pressure.;SOLUTION: A reinforcing construction method for piling steel tower for power-transmission line includes: a column building step in which a plurality of column components are connected in the vertical direction so that a first reinforcement column 22 and a second reinforcement column 23 arranged in a direction crossing the direction of extending power-transmission line 102 are built in a quadrangle area formed by adjoining main columns 12 which are connected; a connection step between reinforcement columns in which both the reinforcement columns 22, 23 are connected to a plurality of parts in a height direction; a connection step between the first reinforcement column and the main column in which two main columns 12 disposed near the first reinforcement column 22 and that column 22 are connected to a plurality of parts in a height direction by a second connecting member 28; and a connection step between the second reinforcement column and the main column in which two main columns 12 disposed near the second reinforcement column 23 and that column 23 are connected to a plurality of parts in a height direction by a third connecting member 30.;COPYRIGHT: (C)2012,JPO&INPIT
