Zusammenfassung:PROBLEM TO BE SOLVED: To set a ratio of a machine cross section to a construction cross section to be small, reduce machine inserting and dragging resistance even in high viscosity soil mud, and improve executability. SOLUTION: Plural excavating spindles 13 are supported in parallel on a multi-spindle excavator body 6 supported by a leader mast 2 or the like to be freely elevatable, and prime mover parts 14 of multi-spindle drive parts to drive the respective excavating spindles to rotate are disposed having height difference in a height direction thereof, thereby a ratio of a construction machine cross section to a construction cross section is set small.
