SCREW, GROUND EXCAVATOR, AND SOIL CEMENT CONTINUOUS WALL CONSTRUCTION METHOD
To provide a screw, a ground excavator, and a soil cement continuous wall construction method capable of reducing the influence of ground excavation at a construction site on the peripheral ground.SOLUTION: A screw 25 is a screw fitted to a ground excavator so as to excavate the ground and agitate a hardening fluid including cement milk and the in-situ soil of the ground, and comprises: a rotary rod 31; and an agitation blade 33 helically provided around the rotary rod 31. The agitation blade 33 has a through-hole 41 formed through the rotary rod 31 in a rotation axis direction, and at least a part of a contour line of the through-hole 41 extends in a direction having a rotation radial-direction component of the rotary rod 31 when seen from the rotation axis direction.SELECTED DRAWING: Figure 2
【課題】地盤掘削において施工現場の周辺地盤への影響を低減するスクリュー、地盤掘削装置、及びソイルセメント連続壁工法を提供する。【解決手段】スクリュー２５は、地盤掘削機に装着され地盤を掘削しセメントミルクを含む硬化性流体と地盤の原位置土とを撹拌するスクリューであって、回転ロッド３１と、回転ロッド３１の周囲に螺旋状に設けられた撹拌翼３３と、を備え、撹拌翼３３には、回転ロッド３１の回転軸方向に貫通する貫通穴４１が設けられており、貫通穴４１の輪郭線の少なくとも一部は、回転軸方向から見て、回転ロッド３１の回転径方向成分を有する方向に延在する。【選択図】図２
