PURPOSE: To make a destructed form compact, to reduce crushed rubble and to reduce construction cost for a wall member with many reinforcements.
CONSTITUTION: On an upper end part, a lower end part and a central part of a wall member 2 of a structure, local cutouts 3 are provided on the same wall surface (4) side as regards the upper end part and the lower end part and a wall surface (5) side opposite to the upper end part and the lower end part as regards the central part. By blasting a column member 7 adjacent to both sides of the wall member 2 in the cross direction and supporting a beam member 6 passing the upper end of the wall member 2, the wall member 2 is deformed by bending it square by vertical force generated on vertical both ends of the wall member 2 so that it is projected to the side of the wall surface (4) opposite to the cutouts 3 at the central part. Thereafter, by folding the wall member 2 in the vertical direction, it is blasted.
