STEEL PIPE PILE ROTARY PRESS FIT METHOD
PROBLEM TO BE SOLVED: To provide a steel pipe pile rotary press fit method capable of pressing a steel pipe pile into the ground with sufficient efficiency even when a crawler crane is not available for obtaining rotational reaction force and to provide a device used in the steel pipe pile rotary press fit method.SOLUTION: A steel pipe pile rotary press fit method for rotationally pressing a plurality of steel pipe piles into the ground in series comprises the steps of: installing a columnar member inside an upper side opening of an existing first steel pipe pile (A); and rotationally pressing a second steel pipe pile into the ground using a rotary press fit device which is fixed to the columnar member installed in the first steel pipe pile through a reaction bar (B).SELECTED DRAWING: Figure 2
【課題】回転反力を得るためにクローラクレーンを利用できない状況であっても鋼管杭を十分に効率的に圧入施工することができる鋼管杭回転圧入工法及びこれに使用される装置を提供する。【解決手段】本発明に係る鋼管杭回転圧入工法は複数の鋼管杭を連続的に地中に回転圧入するためのものであり、（Ａ）既設の第１の鋼管杭の上端側開口内に柱状部材を装着する工程と、（Ｂ）第１の鋼管杭に装着された柱状部材に反力バーを介して固定された状態の回転圧入装置本体を使用して第２の鋼管杭を地中に回転圧入する工程とを備える。【選択図】図２
