LIQUEFACTION COUNTERMEASURE FOUNDATION PILE AND LIQUEFACTION COUNTERMEASURE FOUNDATION STRUCTURE
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.
【課題】地震時に地盤が液状化し、構造物が沈下や倒壊することがある。そこで従来から地盤の液状化対策が考えられてきた。しかし、基礎杭の周辺に砂利等のドレーン材を使用する工法に関しては、砂利等と土が混ざらないようにすることに困難を伴い、安定した水みちの構築が難しい等の問題がある。基礎杭の側面にドレーン材を捲装する工法に関しては、ドレーン材の固定に時間を要する等の問題がある。上記問題点を解決する地盤液状化対策手段を備えた基礎杭及び同基礎杭を使用した建築物の基礎構造を提供する。【解決手段】ポリプロピレンからなる立体網目構造体を筒状に成型した筒状体２と、同筒状体の側面を覆う透水性部材１とからなる液状化防止手段を杭の側面に備えたことを特徴とする液状化対策基礎杭６、及び同基礎杭を用いた基礎構造。【選択図】図３
