CONSTRUCTION METHOD OF BASE STRUCTURE, AND BASE STRUCTURE
PROBLEM TO BE SOLVED: To provide a rational construction method of a base structure and the base structure that enable a bottom slab constructed by a cement press-in construction method to be used as a base structure body when the base structure is constructed by applying the cement press-in construction method to a temporary earth retaining work, at the same time curtailing the construction period and reducing a construction cost.SOLUTION: A construction method of a base structure includes the following steps for: constructing a vertical pit 10 in a ground as a temporary earth retaining structure by repeating steps for pressing-in a ring-form segment 12 into a ground G, excavating the ground G inside the segment 12 that has been pressed in and discharging the soil, and then adding the ring-form segment 12 on top of the existing segment 12; installing a reinforcement cage 14 assembled on the ground by lowering to a bottom part 16 of the vertical pit 10 that has been constructed; and casting concrete 28 such that to bury the reinforcement cage 14 that has been installed on the bottom part 16 of the vertical pit 10.SELECTED DRAWING: Figure 1
【課題】セグメント圧入工法を仮設土留工事に適用して基礎構造物を構築する場合において、セグメント圧入工法で施工される底版を基礎構造物本体として利用することが可能で、工程を短縮し工費を低減することのできる合理的な基礎構造物の施工方法および基礎構造物を提供する。【解決手段】リング状のセグメント１２を地盤Ｇに圧入した後、圧入したセグメント１２の内部の地盤Ｇを掘削して排土し、その後、既設のセグメント１２の上にリング状のセグメント１２を増設する工程を繰り返すことで地中に仮設土留としての立坑１０を構築する工程と、構築した立坑１０の底部１６に地上で地組した鉄筋籠１４を沈設する工程と、立坑１０の底部１６に沈設した鉄筋籠１４を埋設する態様でコンクリート２８を打設する工程とを備えるようにする。【選択図】図１
