Description

本発明は、鋼管杭等の管杭の施工にあたり、横たえられている管杭を立ち上げる際に使用する管杭の吊り起こし装置及び管杭の吊り起こし方法に関する。   The present invention relates to a pipe pile lifting and lowering device and a pipe pile lifting and lowering method for use in raising a laid-out pipe pile in the construction of a pipe pile such as a steel pipe pile.

従来、鋼管杭等の管杭は、地上や運搬船の甲板等の平面上に角材等からなる枕木を杭軸方向に間隔を置いて設置し、当該複数の枕木を介して管杭を平面上に横たえた状態とするとともに、横たえた管杭の底部に転がり防止用のキャンバ(楔部材)を嵌め込み、移動を防止した状態で仮置きされ、施工する際には、管杭の一端側にワイヤを取り付け、当該一端側をクレーンによって吊り上げ、管杭を立ち上げるようになっている(例えば、特許文献1を参照)。   Conventionally, pipe piles, such as steel pipe piles, are installed on the ground or on a plane of the deck of a transport ship at intervals in the axial direction of the piles made of square bars, etc. A camber (barb member) for anti-rolling is inserted into the bottom of the laid pipe pile and temporarily placed in a state in which movement is prevented, and a wire is attached to one end of the pipe pile.
