Abstract

PURPOSE: To enable the natural ground of both hard and soft qualities to be excavated, by providing a rotatable leading pipe pushed forward with a pushing device, with an excavating bit, and by permitting the pipe to be engaged with or separated from an excavating device, to rotate the only the excavating device for excavation.
CONSTITUTION: Inside an internal casing 2 set in a pushed pipe 1, the auger screw 3 of an excavating device is set. On the internal wall surface of a leading pipe 10 set rotatably at the tip of a leading pipe bearing unit 9 via a rugged fitted-on section 11, a tapered surface 12 having an engaging groove 13 is formed. Besides, on the front surface of an excavating head 15, an excavating bit 16 is set, and a tapered surface 17 with an engaging projection 18 is set confronted with the tapered surface 12, respectively. Then, by a pushing device 5, the screw 3 is advanced to excavate natural ground 22, to be separated from the engaging projection 18 and the engaging groove 13. Besides, the leading pipe 10 is pushed forward by a jack 8, and the pushed pipe 1 is pushed forward by the pushing device 5, respectively, and the pipes are propelled in order. As a result, gravels 23 butted to the tip of the leading pipe 10 can be avoided in good order.
