Method For Rehabilitating A Pipe

摘要

Segments (1) are linked in the circumferential direction to assemble a pipe unit (10), which is linked to another pipe unit in the pipe-length direction to assemble a rehabilitation pipe (40) inside an existing pipe (21). Before the pipe unit (10) is assembled or after the pipe unit (10) has been assembled, a spacer (50) is attached to the segment (1) using a spacer holder (60) to prevent the spacer from falling down from the segment. The pipe unit (10) having the spacer (1) attached to the segment (1) is linked to the pipe units that have already been linked. The rehabilitation pipe (40) is positioned relative to the existing pipe (21) using the spacer (50) that is attached to the segment (1). A filler (30) is injected between the positioned rehabilitation pipe (40) and the existing pipe (21).
