Definitions

  • the invention relates to an apparatus for lining pipes or conduits with a helically wound pipe.
  • the invention relates in particular to a winding machine for relining a conduit where the pipe is wound within the conduit.
  • the applicant has developed various technologies to allow trenchless pipe rehabilitation.

  • the method described in that patent included helically winding a strip into a pipe and holding the pipe at a selected diameter during placement within the pipe to be rehabilitated.
  • the method described further included the step of applying pulling force to the newly helically wound pipe to cause the inter engaged edges of the strips forming the pipe to slip with respect with each other so as to increase the diameter of the pipe progressively until it engages the walls of the conduit to be relined.
  • the technology described above can be described as an expanding helically wound pipe technology.
  • the expanding helically wound pipe technology involves positioning a winding cage underground within a host conduit or pipe, or adjacent to a host conduit or pipe, as is described in the above mentioned International Patent Application No. PCT/AU87/00069. This often requires enlargement of the access area adjacent the pipe to be relined to accommodate the winding cage. Enlargement, or "chop-out", typically involves jack hammering concrete which takes considerable effort and time. [0006] Even where pipes are wound at a final diameter using a winding cage underground within a host pipe (without subsequently expanding the wound pipe), enlargement of the access area adjacent the pipe to be relined to accommodate the winding cage is often required.

  • the second radius R ⁇ is smaller than the first radius R ⁇ ( R2 ⁇ Ri).
  • Figure 15 is a diagrammatic end view of the winding cage of Figure 13 and shows a rib support rollers, the rib support roller having a rib support roller axis.
  • the rib support axes are spaced around the longitudinal winding cage axis at a second radius R 2 , and the second radius is smaller that the first radius K ⁇ .
  • the smaller second radius R2 provides a significant advantage. It allows a flanged roller to be used without increasing the overall diameter of the winding cage (in contrast to the arrangement shown in Figure 2a).
  • Each rib support roller 630 has a plurality of flanges 638, the flanges 638 engaging the ribs 20 of the strip 10, thereby laterally guiding the strip 10.
  • the winding machine and winding cage described above with reference to the drawings provides many advantages as compared to earlier winding machines and winding cages. A number of those advantages have been explained above and some further advantages are that the cage 1 10 becomes smaller and is therefore able to be manoeuvred more easily below ground. This is particularly useful where access is tight and where there are direction changes from an access hole.
