METHOD FOR CONFIRMING BEARING GROUND IN CONSTRUCTION OF FOUNDATION PILE AND AUGER FOR THE SAME
To directly measure soil bearing capacity of a bearing ground in a state in which an auger having a spiral blade around a rod shaft is penetrated into the ground when a foundation pile is constructed using the auger.SOLUTION: A hydraulic jack 19 is internally provided on the tip of an auger 1, a loading plate 15 for measuring soil bearing capacity is supported on the tip of a piston, in a state in which the auger 1 is restricted so as not to move in a vertical direction when the tip of the auger 1 reaches a support layer, the hydraulic jack 19 is extended and a load is applied to the loading plate 15 for measuring the soil bearing capacity, a jack pressure and a jack extension amount are measured, and thereby a soil bearing capacity measuring test according to a flat plate loading test is performed.SELECTED DRAWING: Figure 8
【課題】ロッド軸周りに螺旋状の羽根を備えたオーガーを用いて基礎杭を施工するに当たって、前記オーガーを地中に貫入させた状態のままで、支持地盤の地耐力を直接的に測定する。【解決手段】前記オーガー１の先端に、油圧ジャッキ１９を内設するとともに、ピストン先端に前記地耐力測定用載荷板１５を支持し、オーガー１の先端が支持層に達した段階で、オーガー１を上下方向に移動しないように拘束した状態で、前記油圧ジャッキ１９を伸長して前記地耐力測定用載荷板１５に荷重をかけ、ジャッキ圧力とジャッキ伸長量を測定することにより、平板載荷試験に準じた地耐力測定試験を行う。【選択図】図８
