TAPERED PILE WITH ANCHOR AND PILE FOUNDATION USING IT

摘要

PROBLEM TO BE SOLVED: To overcome the disadvantage of a tapered pile, wherein in the case of using a taper pile for supporting a light structure in a medium low layer in the ground whose support layer has a large depth and easy to sink, the tapered pile easily floats due to upward force caused by vertical movement of the ground in case of an earthquake and buoyancy caused by rising of the underground water level. SOLUTION: An anchor 3 is connected to the tip part of the taper pile 2 having a part gradually increased in horizontal sectional area from the tip toward the head, thereby applying pull-out resisting force to the taper pile 2.
