Segment for a rehabilitating pipe |
摘要 |
A segment for a rehabilitating pipe is coupled to another segment in the circumferential and longitudinal directions of a rehabilitating pipe to rehabilitate an existing pipe. The segment has on one coupling surface a protruding part and a recessed part continuous with the protruding part and on another coupling surface a recessed part and a protruding part whose shapes respectively conform to the protruding part and the recessed part of one coupling surface. The protruding part and the recessed part of one coupling surface of one segment is brought into tight surface contact with the recessed part and protruding part of another coupling surface of another segment and interfitted thereto when one and another segments are mutually coupled in the circumferential and longitudinal directions of the rehabilitating pipe.
