PROBLEM TO BE SOLVED: To provide an excellent pipe-jacking method capable of preventing natural downflow of a skid and certainly filling a desired amount of the skid at a desired position of an outer periphery of a drilling body. SOLUTION: This is a pipe-jacking method using a drilling body 3 on which a drilling part 2 is continuously provided on a head end of a base cylinder body 5, a plural number of deriving ports 8 to derive a skid 6 or a solidifying material 7 are provided in a ring on an outer peripheral surface of this base cylinder body 5, a covering body 9 is provided on the base cylinder body 5 in the neighborhood of these deriving ports 8, a partition body 10 to partition a space part in the peripheral direction in a state of including at least one of the deriving ports 8 is provided in parallel in the space part formed between this covering body 9 and the base cylinder body 5 and a discharge port 11 to discharge the aforementioned skid 6 or the solidifying material 7 is provided in the space part partitioned by this partition body 10.
