CONSTRUCTION METHOD OF STEEL PIPE SHEET PILE WELL FOUNDATION
To provide a construction method of steel pipe sheet pile well foundation allowing appropriate filling of mortar in a joint for connecting adjacent steel pipe sheet piles.SOLUTION: In a construction method of steel pipe sheet pile well foundation in which joints 2 of adjacent steel pipe sheet piles 1 are fitted to each other and multiple steel pipe sheet piles 1 are placed into the ground G of a water bottom G1, and closedly combined to form the foundation, a scouring state of the ground G placed with the multiple steel pipe sheet piles 1 is surveyed, and at least one of a countermeasure of precedent improvement of a ground area where the scouring is expected, and a countermeasure of filling a grout leakage preventive material 4 to the scoured recessed part M of a scoured area to cover the joint 2 exposed by scouring, is performed.SELECTED DRAWING: Figure 2
【課題】隣り合う鋼管矢板同士を繋ぐ継手内を好適にモルタル充填することを可能にする鋼管矢板井筒基礎の施工方法を提供する。【解決手段】隣り合う鋼管矢板１の継手２同士を嵌合させつつ複数の鋼管矢板１を水底Ｇ１の地盤Ｇに打設し、閉鎖形状に組み合わせてなる鋼管矢板井筒基礎の施工方法において、複数の鋼管矢板１を打設した地盤Ｇの洗掘状態を探査し、洗掘が予測される地盤領域を先行改良する対策と、洗掘が生じている領域の洗掘凹部Ｍに、洗掘によって露出した継手２を被覆するようにグラウト漏洩防止材４を配設する対策の少なくとも一方の対策を講じる。【選択図】図２
