STOPPER FOR USE WITH FOUNDATION PILE HAVING FOUNDATION VIBRATION SHUTTING FUNCTION AND METHOD FOR INSTALLING THE SAME

PROBLEM TO BE SOLVED: To easily adjust on-site the clearance between a stopper, which is provided between the outer surface of a foundation pile and the inner surface of an outer pipe, and an opposite surface. SOLUTION: A stopper 20 is installed between the outer pipe 3 of a foundation pile having a foundation vibration shutting function and the foundation pile. In this case, the stopper 20 comprises stopper holding means 21 almost equally spaced in the circumferential direction on the inner surface of the outer pipe 3 and a stopper member 25 comprising a stopper base 22 inserted into each stopper holding means from above the outer pipe and a stopper holding plate 23 mounted on the stopper base 22 via intermediate plates 24, the thickness and number of the intermediate plates 24 being variable depending on the interval between the outer pipe 3 and the foundation pile.
