摘要： A method of excavating an underground continuous ditch by rotating a chain type cutter 4 while pressing the cutter horizontally against the ground A, with the cutter positioned underground. According to this method, when a lower ground portion is left unexcavated due to a deficiency in traversing force at the lower portion of the cutter particularly during excavation at a large depth, the rotating direction of the cutter 4 is changed from a rake-up direction in normal excavation to a rake-down direction and excavation is performed while the cutter is moved vertically, to excavate the lower ground portion (A1) left unexcavated.
