Definitions

  • This invention relates to methods for connecting together pipes, and especially to methods for connecting existing drains to sewers which have been renovated by slip lining with plastic pipe.
  • a method of lining sewers with short lengths of plastic pipe with a "snap on" clip fastening arrangement machined in the ends of the pipe is known.
  • the sewer is first surveyed and the approximate position of live drains, steps and protruding laterals are noted.
  • the pipe lengths used are planned to allow for access to the sewer through the manhole as a maximum length, and this length is varied to prevent a drain entry in ' the area of a pipe joint.
  • the pipe ends ' are prepared to form a snap closure and are fitted with an induction ring.
  • OMPI drawn through, snapped together and fused with the internal induction ring connected to an R.F. generator until the pipe length that requires drain access is reached.
  • a closed circuit television camera is then drawn through, contained within a "cage", the outer ribs of which are graduated. This cage is butted to the last piece of liner pipe inserted, and the camera scanned until the drain connection is located- The diameter, longitudinal and radial position of this drain, relative to the last pipe liner pipe is made by reference to the graduated ribs of the cage.
  • the measurements are transposed to the next length of liner and a hole is cut, appropriate to the size of the drain. This next length of liner is then inserted and positioned in the same way ' as preceding lengths.
  • a flexible bag is introduced into the hole made in the l-iner for coi ⁇ munication with"the existing drain, said bag being sealed to the liner about said hole and pressure being applied to said bag to force at least a portion of the body of the bag into the existing drain and so as to bridge the gap between the liner and the existing sewer at the point of entry of the existing- drain.
  • material is introduced via the wall of the flexible bag into the space between the liner and the original sewer.
  • the present invention also provides apparatus for sealing the gap between the liner and the existing sewer, at the point of entry of an existing drain into the sewer, said apparatus including means for locating about the hole in the liner, communicating with the existing drain, a flexible bag, attachable to or attached to said means such that pressure applied to the body of the bag will force the body of the bag into said existing drain so as to seal the gap between the liner and the existing sewer.
  • Figure 2 illustrates the same method and apparatus as Figure 1 but at a later stage in the operation of the method.
  • an existing sewer 1 is connected to an existing drain 2.
  • a polyethylene liner 3 having a hole 3a_ therein allowing communication between the interior of sewer 1 and drain 2.
  • a plastics ring 5 is fused into hole 3a making use of an induction ring 4 which is heated up by an induction generator (not shown) .
  • Clipped to ring 5 by means of sleeve 6 is a bag 7 made of flexible, air tight material. The neck ' ⁇ of the bag is formed into an "0" ring 7a_ which locates into a groove formed in the wall of retaining sleeve 6.
  • an extraction cord 8 which is fed through to the manhole.
  • the entire length of sewer may be sealed, all the drain connections inflated and the entire length of lining grouted.
  • the grouting material instead of being fed through the wall of the bag via pipe 9 is instead fed by a suitable conduit to the gap via ring 5 or sleeve 6.
  • the grouting material may be any suitable material such as a foamable polyurethane material. Such a material can be injected into the gap where it may expand to many times its original volume so as effectively to seal the gap where the drain connects to the sewer.

Abstract

Un procede permettant d'assurer l'etancheite de l'espace entre un tuyau d'egout (3) et une conduite de connexion (2) a l'egout, telle qu'un drain, consiste a amenager un trou dans le tuyau en communication avec la conduite, a sceller un sac flexible (7) sur le tuyau autour de ce trou, et a appliquer une pression sur le sac pour forcer au moins une partie du sac d'entrer dans la conduite de maniere a enjamber l'espace entre le tuyau et l'egout au point de connexion de la conduite. De preference, un materiau approprie de jointoiement au mortier liquide est ensuite introduit dans l'espace de maniere a entourer le sac lorsqu'il enjambe l'espace, creant ainsi un joint permanent entre le tuyau et la conduite de connexion.
