PROBLEM TO BE SOLVED: To provide a foundation pile having ground liquefaction countermeasure means and a foundation structure of a building using the foundation pile for solving the problems, since there is such a problem as being difficult to construct a stable waterway due to causing the difficulty in preventing ballast and soil from being mixed regarding a method of using a drain material such as ballast on the periphery of the foundation pile, and since there is such a problem as requiring time for fixing the drain material regarding a method of winding the drain material on a side surface of the foundation pile, in conventionally thinking a liquefaction countermeasure of the ground since a structure occasionally sinks and collapses when the ground is liquefied in an earthquake.SOLUTION: A liquefaction countermeasure foundation pile 6 and a foundation structure using the foundation pile, has on a side surface of a pile, liquefaction prevention means composed of a cylindrical body 2 made by molding a three-dimensional network structure composed of polypropylene in a cylindrical shape, and a water permeable member 1 for covering a side surface of the cylindrical body. |
