摘要： PROBLEM TO BE SOLVED: To prevent the entangling of wires by winding up a weight with a bit in an excavating casing, dropping it by the tare weight for an excavation, and making the weight and the wires independently rotatable around the axis via a swivel joint. SOLUTION: An excavating casing 4 is rotated by the hydraulic cylinder of a driving device and pressed into the ground. The winding up of wires 12 by a winch and the release of a clutch are conducted in turn, and the ground is excavated via the ascent and drop of a weight 11. When the excavating casing 4 is rotated, the sediment in the casing 4 is rotated together with the casing 4, and the weight 11 is also rotated together. A swivel joint 31 is inserted between the weight 11 and the wires 12 not to convey the rotation of the weight 11 to the wires 12, and the entangling of the wires 12 is prevented.
