Summary:PROBLEM TO BE SOLVED: To provide a jacking auxiliary device for a shielding machine and a jacking method for the shielding machine for preventing shaking of a segment remaining in a cylindrical body after the shielding machine passes. SOLUTION: An entrance packing 17 is provided on an inner peripheral face 14 of pithead concrete 16 of a shaft, the cylindrical body 13 is provided in the vicinity of a pithead 15, and a filling bag 9 and an entrance packing 19 are provided on an inner peripheral face 18 of the cylindrical body 13. The cylindrical body 13 is used as a start chamber of the shielding machine 1. The shielding machine 1 starts from the start chamber 11 while assembling a temporarily assembled segment 5 inside a skin plate 7. The entrance packing 17 and the entrance packing 19 prevent underground water from flowing into a start shaft 23 when the shielding machine 1 starts to ensure water stopping property. After the shielding machine 1 passes, filler 27 is filled into the filling bag 9 to inflate it, and the filling bag 9 is brought into contact with an outer peripheral face of the temporarily assembled segment 5 to fix a shape and a position of the temporarily assembled segment 5.
