| description | PROBLEM TO BE SOLVED: To reliably form an enlarged-diameter part in part of a drilling hole while reducing resistance from a ground when drilling a hole in the ground to be larger than the diameter of an excavation rod.SOLUTION: A ground excavator has an enlargement excavation member 4 which is a member for drilling a hole in the ground to be larger than the diameter of an excavation rod 1 and is supported so as to rotate relative to the excavation rod 1 so that a drilling direction can be freely varied according to a drilling angle of the excavation rod 1 with respect to the ground. The enlargement excavation member 4 is supported, for example, to be rotatable with respect to a revolving shaft 3 provided in the excavation rod 1, or is supported by a shaft which is rotatable with respect to the excavation rod 1.
【課題】地盤を掘削ロッド径よりも拡大して掘削する場合に、地盤からの抵抗を減らすとともに、掘削孔の一部に拡径部を確実に形成する。【解決手段】地盤掘削装置は、地盤を掘削ロッド１の径よりも拡大して掘削する部材であって、地盤に対する掘削ロッド１の掘進角度に応じて掘進方向の向きを自在に変化させるように掘削ロッド１に対して回転自在に支持された拡大掘削部材４を有する。拡大掘削部材４は、例えば、掘削ロッド１に設けられた回転軸３に対して回転自在に支持され、あるいは掘削ロッド１に対して回転可能な軸に支持されている。【選択図】図３ |
