JACKING METHOD AND PIPE FOR USE THEREIN

PROBLEM TO BE SOLVED: To provide a jacking method whereby a filler of the kind adapted to the condition of the natural ground around a pipe is discharged by an appropriate amount even if the condition of the natural ground varies circumferentially and to provide pipes for use therein. SOLUTION: This pipe 1 is disposed behind an excavator for excavating a shaft in the natural ground G, and fins 2 by which a clearance formed between the outer peripheral surface of the pipe 1 and the natural ground G is circumferentially divided into at least two parts are provided on the circumferential face of the pipe 1 in order to discharge a filler into the clearance. Filler discharge parts 5a, 5b for discharging the filler into the divided clearances 8a, 8b are provided between the fins 2 to discharge the filler into the clearances 8a, 8b while adjusting the amount of the filler differently for the clearances 8a, 8b or to discharge different fillers into the different clearances 8a, 8b.
