METHOD OF PERFECTLY BACKFILLING HOLE FROM WHICH PILE IS PULLED OUT
To provide a method of perfectly backfilling a hole from which a pile is pulled out, when backfilling the pile-pulled-out hole with soil, performing backfilling without generating a gap in the backfilling soil so as to prevent ground settlement from occurring thereafter.SOLUTION: A backfilling method, when backfilling with soil, a hole from which an existing pile driven into a ground is pulled out, regenerates a rigid ground without leaving a gap in the backfill soil. Using a heavy pressure vibration applying mechanism 1 constituted by: a weight hung on a construction machine such as a crane vehicle and a pile extractor; a plate body disposed on the soil backfilling a pile-pulled-out hole 6; and a vibration generating device interposed between the weight and the plate body, the method generates a heavy pressure vibration in the plate body, to push the plate body against a surface of the soil thrown into the pile-pulled-out hole 6, so as to achieve backfilling with the soil rigidly with the heavy vibration.SELECTED DRAWING: Figure 2
【課題】杭抜き穴へ土を充填して埋め戻す際、爾後に地盤沈下が生じないよう埋め戻した土内に空隙を生じさせることなく充填してなる杭抜き穴への完全埋め戻し工法を提供する。【解決手段】地中に打ち込まれた既設杭を抜き取った後の穴に土を埋め戻す際、埋め戻した土の中に空隙を残すことなく強固な地盤に再生する埋め戻し工法であって、クレーン車又は杭抜き機等の建設機械に懸吊された重錘と、杭抜き穴内６に埋め戻された土の上に配置される板体と、前記重錘と板体間に介在させてなる振動発生装置とで構成された重圧振動付与機構１により、前記板体に発生させた重圧振動によって、杭抜き穴６に投入した土面に前記板体を押し当て、その重圧振動によって土を強固に充填し埋め戻す。【選択図】図２
