Abstract
A rehabilitating pipe segment for assembling a rehabilitating pipe inside an existing pipe. The rehabilitating pipe segment has first and second segment halves connectable together to provide for the rehabilitating pipe segment an internal surface plate and side and end plates surrounding peripheral edges of the internal surface plate. The first and second segment halves are configured to move relative to one another in a width direction of the rehabilitating pipe segment corresponding to a pipe length direction of the rehabilitating pipe so that the first and second pipe segment halves expand and contract to make the width of the rehabilitating pipe segment variable in the width direction of the rehabilitating pipe segment.
