CONSTRUCTION METHOD OF CONTINUOUS UNDERGROUND WALL AND STEEL PIPE PILE
To construct a continuous underground wall having a high strength with a smaller number of working man-hours at low cost without generating industrial wastes.SOLUTION: A method for constructing a continuous underground wall R includes: a steel pipe installation step of continuously and alternately installing a first steel pipe 1 and a second steel pipe 2; a drilling step of drilling the insides of the first steel pipe 1 and the second steel pipe 2; a first solidification material filling step of pulling out the first steel pipe 1 while or after filling the first steel pipe 1 with concrete; and a second solidification material filling step of pulling out the second steel pipe 2 while disturbing first piles 1Aa and 1Ab with a claw part 3 projecting to the outside of the second steel pipe 2 while or after filling the second steel pipe 2 with concrete. Both sides of the second pile 2Aa are connected to the first piles 1Aa and 1Ab by replenishing concrete while disturbing the first piles 1Aa and 1Ab with the claw part 3.SELECTED DRAWING: Figure 7
【課題】産業廃棄物を生じることなく、高強度な連続地中壁を少ない作業工数と低コストで施工できる。【解決手段】連続地中壁Ｒの施工方法は、第一鋼管１と第二鋼管２を連続して交互に打設する鋼管打設工程と、第一鋼管１及び第二鋼管２内を掘削する掘削工程と、第一鋼管１内にコンクリートを充填しながらまたは充填した後に第一鋼管１を引き抜く第一固化材料充填工程と、第二鋼管２内にコンクリートを充填しながらまたは充填した後に第二鋼管２の外側に突出する爪部３によって第一杭１Ａａ、１Ａｂを乱しつつ第二鋼管２を引き抜く第二固化材料充填工程とを備えた。爪部３で第一杭１Ａａ、１Ａｂをかき乱しながら補充コンクリートによって第二杭２Ａａの両側部を第一杭１Ａａ、１Ａｂと連結した。【選択図】図７
