CASING TUBE RECOVERY SYSTEM, AND CASING TUBE RECOVERY METHOD USING THE SAME
PROBLEM TO BE SOLVED: To provide a casing tube recovery system and a casing tube recovery method using the same, the casing tube recovery system being capable of pulling up upper and lower casing tubes with respective connecting parts separated with a distance, after connecting the casing tubes readily and safely.SOLUTION: A casing tube recovery system includes a pressure bearing body 5 extended toward an inner peripheral surface of a casing tube by a hydraulic driving device, the pressure bearing body being disposed on a columnar body 3 hung and spanned between upper and lower casing tubes 1, 2 with respective connecting parts separated with a distance, and extended when driven by the hydraulic driving device. The casing tube recovery system is inserted into the casing tubes 1, 2, and the pressure bearing body 5 is adhered on an inner periphery of the casing tube. Then, the upper and lower casing tubes 1, 2 are connected from inside by the casing tube recovery system and the upper casing tube is pulled up by an all-around rotary excavator, thus pulling up the lower casing tube simultaneously.SELECTED DRAWING: Figure 1
【課題】簡単かつ安全に連結部の離れた上下のケーシングチューブを結合させて引き上げることができるケーシングチューブ回収装置およびそれを使用したケーシングチューブ回収方法を提供する。【解決手段】連結部の離れた上下のケーシングチューブ１，２の相互に渡るように吊降す柱状体３に油圧装置駆動で張り出すケーシングチューブ内周面への支圧体５を油圧装置駆動で張り出すように設けたケーシングチューブ回収装置をケーシングチューブ１，２内に挿入し、支圧体５をケーシングチューブ内周に圧接させて上下のケーシングチューブ１，２をケーシングチューブ回収装置で内側から連結し、全周回転式掘削機械で上方のケーシングチューブを引き上げることで、下方のケーシングチューブも同時に引き上げる。【選択図】 図１
