<p><P>PROBLEM TO BE SOLVED: To efficiently repair an inner face of an existing pipe conduit by using a long segment piece. <P>SOLUTION: Rotating members 3 rotatable in the circumferential direction are mounted on ring members inscribed and fixed to the existing pipe conduit with a specific span, both end parts of a first segment piece 4a are fixed to the rotating members 3 attached to the ring members opposite to each other through the span at the upper circumferential positions, the rotating members fixing both end parts of the segment piece 4a are rotated, both end parts of a second segment piece 4b are fixed to the rotating members 3 at a circumferential position approximately same as the fixing position of the segment piece 4a in a state of butting the segment piece 4a and the circumferential end face, further a third segment piece 4a is fixed to the rotating members 3 by the similar procedure, and then three segment pieces 4a, 4b, 4c are assembled into the tube shape, thus the inner face of the existing pipe conduit can be efficiently repaired by using the long segment pieces. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
