<P>PROBLEM TO BE SOLVED: To provide a method for repairing pipe line thAT CAN easily perform The lining of the whole periphery of the inner surface of a pipe line in a repair interval even while a water discharge hose for discharging water dammed on the upstream side of the repair interval to the downstream side is caused to pass into the repair interval. <P>SOLUTION: The water discharge hose 22 is laid through the repair interval from a water stop position of the upstream side in the repair interval to a position of the downstream side, the water dammed on the upstream side is discharged to the downstream side by means of the water discharge hose 22 laid in the repair interval and, at the same time, the whole periphery of the inner surface of the pipe line is covered with the lining material 1. Further, a part of the water discharge hose 22 is raised by the support carriage 23 movable in the length direction of the pipe line, the support carriage 23 is moved in the length direction of the pipe line, at the same time, the inner surface of the pipe line just below the part of the water discharge hose 22 raised by the support carriage 23 is covered with the lining material 1 and, thereby, the lining of the lower part of the pipe line is performed over the whole region in the length direction in the repair interval. <P>COPYRIGHT: (C)2013,JPO&INPIT |
