Abstract
Segments are linked in the circumferential direction to assemble a pipe unit, which is linked to another pipe unit in the pipe-length direction to assemble a rehabilitation pipe inside an existing pipe. Before the pipe unit is assembled or after the pipe unit has been assembled, a spacer is attached to the segment using a spacer holder to prevent the spacer from falling down from the segment. The pipe unit having the spacer attached to the segment is linked to the pipe units that have already been linked. The rehabilitation pipe is positioned relative to the existing pipe using the spacer that is attached to the segment. A filler is injected between the positioned rehabilitation pipe and the existing pipe.
