Abstract

A substantially rigid thermoplastic pipe 10, manufactured in a flattened and folded form (eg. Figs 9-11) so as to have a memory in this condition is stored in such form, heated eg. by box 140 to make it pliable for installation and positioned in an existing pipe 90. The new pipe or liner 10 is rounded by placing heated fluid in the passages along the folds of the pipe 10 while its leading end is restricted eg. by a clamp or inflatable plug (222, Fig 29). Alternatively, an inflatable plug (eg Fig 30) may be propelled to the leading end of the new pipe 10 after its insertion and then fully inflated to block such end and thereby enable full rounding and expansion of the remainder of the new pipe 10. Lateral pipe may be lined. A cutter 200 with an inflatable locking sleeve 216 and cutting blades 212 may be passed down the pipe or liner 10 to free the leading end. The pipe 10 may be removed from an existing pipe by re-heating to produce collapse as a result of memory and pulling the collapsed liner 10 from the existing pipe. A clamp (276, Fig 39) which can be released by pulling on a wedge (282) after pulling the leading end of the liner 10 into position may be provided. A collapsable frog or pulley support (152, Figs 14-16) mounted at the pipe lateral/main junction may be used with a cable (168) for pulling the liner 10 into the existing pipe lateral.
