Pile foundation structure, the construction method of the pile foundation structure and the pile to be used in these

摘要

PROBLEM TO BE SOLVED: To provide a pile foundation structure capable of increasing a force (stability) resistant to pile extraction, without depending on enlargement of a pile diameter or an increase in embedment length, a method for constructing the pile foundation structure, and a pile for use in them.;SOLUTION: In a pile foundation structure, a partition plate 10 is provided in a foundation pile P comprising a hollow tube, and the foundation pile is split into upper and lower vertical portions 11 and 12 by the partition plate. At least a part 12a of the lower portion 12 of the foundation pile driven into ground G is hermetically sealed by being saturated with water or water and a ground material. Thus, a suction force (suction) resistant to a pull-out force is generated when the pull-out force acts on the foundation pile.;COPYRIGHT: (C)2012,JPO&INPIT
