Definitions

  • the present invention generally relates to a pipe repair sleeve and method of repairing pipes, tunnels, conduits and other similar structures as well as to a method for repairing underground pipes by inserting an expandable sleeve inside the pipe and expanding the same to seal a damaged or leaking portion of the pipe.
  • One method involves forcing a sealing fluid into the pipe lining under the pressure through the damaged portion in the pipe.
  • Another method involves coating the interior of the underground pipe with a sealing material in order to repair the damaged portion of the pipe.
  • British Patent 2,136,912, BARRY discloses a method of sealing pipes having a sleeve impregnated with a curable resin which is placed around an inflatable and collapsable bag.
  • the sleeve and bag are attached to a. pulling line and introduced into the damaged part of the pipe.
  • the bag is inflated thereby expanding the fiber glass laminate sleeve into pressure contact with the inner wall of the pipe. After the resin hardens, the bag is collapsed and moved.
  • U.S. Patent 4,589,447, CANE et al. discloses a method of inserting a coiled element into damaged tunnel or conduit. When the coil element is positioned at a damaged location, the coil element unwinds and expands outwardly forcing the sleeve on its outer surface against the wall of the conduit and seals the damaged portion of the tunnel.
  • U.S. Patent 4,581,801, KOBUCK et al. discloses a method which uses a metal sleeve 16 and an expander element 24 which are both inserted into a pipe. The expander element causes a sleeve to expand against the inner surface of the tube.
  • U.S. Patent 4,347,018, WRIGHTSON et al. discloses a method of repairing the lining of tunnels, conduits and the like wherein an overlapped pipe is inserted into the tunnel. The steps holding the pipe in its hold-up state are released forcing the pipe to extend.
  • U.S. Patent 4,361,451, RENAUD discloses a lining arrangement wherein a lining sleeve and inflatable envelope having a layer of resin therebetween are introduced into a conduit. The envelope is inflated and forces the sleeve against the inner wall of the conduit.
  • Another object of the present invention is to provide a new and improved underground pipe repair method which minimizes the labor required and the necessary time for repairing the same.
  • a further object of the present invention is to provide a new and improved internal pipe repair sleeve which expands and locks in position inside the pipe structure to seal a damaged or leaking part of the pipe.
  • a coiled repair sleeve having edges with locking members whic is expanded, for example, by means of an air bag inserted into the coil of sheet material, covered with elastic gasket material, which forms the sleeve.
  • the repair sleeve with the air bag inserted is moved to the location of the damage or leak; upon reaching the site of the damage, the air bag, or other means of expansion, is inflated or otherwise expanded so as to uncoil the sleeve and compress the gasket material against the inside of the pipe.
  • the air bag is then deflated, the uncoiled sleeve retracts to a certain degree due to its spring-type property and the elasticity of the gasket material.
  • the male locking member of the sleeve slips into the groove of the female locking member of the sleeve to form a continuous interior sleeve inside the pipe.
  • the air bag is removed from the pipe structure.
  • the present invention is directed to a generally elongate member with interlocking longitudinal edges including a sheet of material having two longitudinal edges, and means for locking associated with the longitudinal edges adapted to fasten the longitudinal edges of the sheet together to form the sheet into a generally tubular configuration, wherein the sheet is composed of flexible material, preferably selected from the group consisting of metal and plastic, and more preferably metal, and preferably wherein the sheet is coiled.
  • the means for locking includes a male locking member and a female locking member adapted to mate with the male locking member.
  • the male locking member includes an elongate element having a predetermined length and the female locking member includes an outer lip having a length substantially equal to the length of the male locking member and an inner lip having a length shorter than the length of the length of the outer lip.

Abstract

La présente invention se rapporte à un manchon et à une garniture intérieure pour la réparation de conduites, comportant des éléments à blocage par interpénétration et se présentant sous la forme d'une feuille enroulée en spirale recouverte d'un joint d'étanchéité compressible. Un sac d'air est introduit dans le manchon enroulé et amené jusqu'à l'endroit où la conduite est endommagée. Une fois en place, le sac d'air est gonflé. A la suite du gonflage, le manchon de réparation se déroule et le joint d'étanchéité qui l'entoure est comprimé contre l'endroit où la conduite est endommagée. Par dégonflage du sac d'air, le manchon s'enroule à nouveau et force une extrémité mâle à pénétrer dans l'extrémité femelle, formant ainsi à l'intérieur de la conduite un manchon continu à blocage par interpénétration de l'élément mâle dans l'élément femelle. Après installation du manchon de réparation dans la conduite, le sac d'air est retiré du manchon.
