ERECTION METHOD OF CORE MATERIAL
PROBLEM TO BE SOLVED: To provide an erection method of a core material in which a core material can be inserted into a soil cement column and erected while securing verticality accurately with a simple method on constructing a soil cement column row wall.SOLUTION: An erection method of a core material includes: a first step of installing an acceleration sensor capable of replying to static acceleration in the vertical direction directing a sensitivity direction to the direction perpendicular to an axis center of the core material in the core material disposed in a standing state, and hanging it in the upper part of a soil cement column; a second step of adjusting so that the posture of the core material of the standing state becomes vertical; and a third step of inserting and erecting the core material to a desired depth, while ensuring a slant angle to the vertical axis of the core material found from the component force in the sensitivity direction of the gravity acceleration detected by the acceleration sensor.SELECTED DRAWING: Figure 1
【課題】ソイルセメント柱列壁を構築するにあたり、簡略な方法で精度よく、鉛直性を確保した状態で芯材をソイルセメント柱に挿入し建て込むことの可能な、芯材の建込み方法を提供する。【解決手段】起立状態に配置した芯材に、芯材の軸心と直交する方向に感度方向を向けた、鉛直方向の静加速度に応答可能な加速度センサを設置し、ソイルセメント柱の上方に吊持する第１の工程と、起立状態の芯材の姿勢が、鉛直になるよう調整する第２の工程と、加速度センサにより検知される重力加速度の、感度方向の分力から求めた芯材の鉛直軸に対する傾斜角度を確認しつつ、芯材を所望の深度まで挿入し建込む第３の工程と、を備える。【選択図】図１
