STEEL PIPE INSTALLATION DEVICE, AND STEEL PIPE INSTALLATION METHOD
To provide a steel pipe installation device which can efficiently and safely install a steel pipe.SOLUTION: A steel pipe installation device has: an excavation shaft member 3 having an excavation bit 2 at its tip; a rotary drive device 5 for rotating the excavation shaft member 3; and a cylindrical earth removal member 7 having substantially the same diameter as that of a steel pipe P to be installed. The cylindrical earth removal member 7 has: an earth removal port 71 for removing excavation muck blown up through the steel pipe P to be installed; a connection part 75 for attachably/detachably connecting the cylindrical earth removal member 7 to/from the upper part of the steel pipe P to be installed; and a stopper 77 for securing a rotational reaction force during operation of the rotary drive device, for the steel pipe P. The steel pipe installation device having such a structure dispenses with troublesome work such as extension and separation of a plier, dispenses with extension of the excavation shaft member associated with the extension of the plier, and can efficiently and safely install the steel pipe.SELECTED DRAWING: Figure 1
【課題】鋼管類の打設を効率的にかつ安全に進めることを可能にする鋼管類打設装置を提供する。【解決手段】鋼管類打設装置は、先端に掘削ビット２を備えた掘削軸部材３と、掘削軸部材３を回転させるための回転駆動装置５と、打設する鋼管類Ｐとほぼ同径の筒状排土部材７を有している。筒状排土部材７は、打設する鋼管類Ｐを介して吹き上げられた掘削ずりを排出するための排土口７１と、打設する鋼管類Ｐの上部に対し筒状排土部材７を着脱自在に接続するための接続部７５と、回転駆動装置の作動時の回転反力を鋼管類Ｐに確保するためのストッパー７７を有している。このような構成の鋼管類打設装置によれば、ヤットコの継ぎ足しや切り離しといった煩わしい作業が一切不要で、また、ヤットコの継ぎ足しに伴う掘削軸部材の継ぎ足しも一切不要となり、鋼管類の打設を効率的にかつ安全に進めることが可能になる。【選択図】図１
