Abstract

PURPOSE: To remove extra-banking concrete without breaking by a method in which pile concrete is placed under a condition that a tool by which the adherence of concrete to iron bars is prevented is attached to the iron bars positioned above the upper level of a set pile level in such a way as to cause cracks to occur in the side area of the pile, and then the tool is lifted up.
CONSTITUTION: Under a condition that a tool 2 by which the adherence of concrete to iron bars 1 is prevented is attached to the iron bars 1 positioned above the upper end P of a set pile level, pile concrete C is placed, and a hanging metal 3 is buried in an extra-banking concrete portion C' in unhardened state. Then, the area around the pile is excavated to form an excavated portion 4 and a hole is drilled in the side of the pile concrete C. A wedge 6 is then inserted into the hole in such a way as to cause cracks to take place. Then, the hook of a lifter is coupled with the hanging metal 3, the hanging metal 3 is lifted up, and the blocks of the extra-banking concrete C' are removed.
