PROBLEM TO BE SOLVED: To provide an electrode for electrolytically corroding a pile core material of a concrete structure, which enables the core pile material of the reinforced concrete structure to be electrolytically corroded and removed in a short period of time, and a method for electrolytically corroding and removing the pile core material by using the electrode.;SOLUTION: This electrode for electrolytically corroding the pile core material comprises: a balloon-like pressurizing member 5 which is inserted into a hollow part of the pile core material 2 in a part-to-be-destroyed of the reinforcing concrete structure 100 and which can be expanded by a fluid; an upper go-around electrode 6 which makes the circuit of an upper part of the part-to-be-destroyed of the pile core material 2; a lower go-around electrode 7 which make the circuit of a lower part of the part to be destroyed; vertical connection electrodes 8 which are provided in a vertically long manner in a plurality of places by connecting the go-around electrodes 6 and 7 together; and an insulating support frame 9 which is provided in the electrode so as to maintain an interval between the pile core material 2 and the electrode. By using the electrode for electrolytically corroding the pile core material, the pile core material 2 is anode-dissolved in the positions of the upper and lower go-around electrodes and divided in a cross-sectional manner, and concurrently with that, anode-dissolved in the position of the vertical connection electrode and divided in the vertical direction of the pile core material 2; and the tubular pile core material is divided into a plurality of vertically long pieces.;COPYRIGHT: (C)2005,JPO&NCIPI
