| Zusammenfassung: | To provide a soil cement pile construction method capable of efficiently constructing a soil cement pile of the required depth, even in a low overhead clearance or restricted conditions where an upper space is limited.SOLUTION: In a soil cement pile construction method, while adding extension rods to an excavating rod provided on an excavating-agitating head, core materials are built while being added on a soil cement pile which is created by rotationally press-fitting the excavating-agitating head into the ground. The extension rod is gripped from the side by a rotary drive device of a rotary press-fitting device provided with the rotary drive device for rotating a rod member gripped from the side while moving along a leader, via a rod attachment, and the excavating-agitating head is rotationally press-fit into the ground by the rotary press-fitting device.SELECTED DRAWING: Figure 1
【課題】上空を制限される低空頭空間や狭隘な条件下にあっても、作業効率よく必要深さのソイルセメント杭を構築することの可能な、ソイルセメント杭の施工方法を提供する。【解決手段】掘削撹拌ヘッドに備えた掘削ロッドに対して継足ロッドを継ぎ足しながら、該掘削撹拌ヘッドを地中に回転圧入して造成したソイルセメント柱に、芯材を継ぎ足しながら建て込む、ソイルセメント杭の施工方法であって、リーダーに沿って移動しつつ側方から把持した棒状部材を回転させる回転駆動装置を備える回転圧入装置の、前記回転駆動装置にロッド用アタッチメントを介して前記継足ロッドを側方から把持させ、前記掘削撹拌ヘッドを、前記回転圧入装置にて地中に回転圧入することを特徴とする。【選択図】図１ |
