- 中央のオーガー(13)が両側のオーガー(14、14)よりも長い三連のオーガー装置(11)を用い、中央が深い縦孔(19)で両側が浅い縦孔(20、20)となる三連縦孔(21)を掘削し、この三連縦孔(21)の掘削時に、前記中央のオーガー(13)のヘッド(16)の吐出口(13a)からだけセメントミルクを吐出するとともに、前記中央のオーガー(13)の軸部の撹拌翼(18)により、前記セメントミルクと掘削土を撹拌混合し、吐出されたセメントミルクが上昇して両側の浅い縦孔で両側のオーガー(14、14)の軸部の攪拌翼(18)で攪拌されていくことで三連縦孔(21)内をソイルセメント状にし、前記オーガー装置(11)の抜き取り後に中央の深い縦孔(19)内に親杭(22)を埋め込んで単位壁(23)を形成し、この単位壁(23)を浅い縦孔(20)が重なり合うように並べて施工することにより、各単位壁(23)の固化したソイルセメントで連続する山留め壁(24)を構築する山留め壁の構築工法。
