STRUCTURE FOUNDATION REINFORCEMENT METHOD
To provide a reinforcement method capable of preventing construction of an underground consolidated body required for reinforcement from being larger than required.SOLUTION: A structure foundation reinforcement method of the present invention includes boring a structure foundation (10: pile foundation having footing 1) from a predetermined position of its outer periphery, setting the predetermined position so that a resistance force (F) obtained by constructing an improvement body (3) is larger than a horizontal external force (H), injecting a solidification material from an injection device (4A) in a drilled hole, pulling up the structure foundation (10) including the lower surface up to ground side from the lower surface, and constructing the improvement body (3).SELECTED DRAWING: Figure 1
【課題】補強に必要な地中固結体を必要以上に大きく造成してしまうことが防止することが出来る補強方法の提供。【解決手段】本発明の構造物基礎補強方法は、構造物基礎（１０：フーチング１を有する杭基礎）の外周の所定位置から削孔し、所定位置は、改良体（３）を造成して得られる抵抗力（Ｆ）が水平外力（Ｈ）より大きくなる様に設定され、削孔孔内の噴射装置（４Ａ）から固化材を噴射して、構造物基礎（１０）の下面を含めて当該下面よりも地上側まで引き上げて改良体（３）を造成する。【選択図】図１
