Definitions

  • an assembly for sealing a manhole is provided and a sealing member is placed against a wall of the manhole at an area prone to water infiltration.
  • a manhole liner is placed against the walls of the manhole and the sealing member, creating a seal at the areas prone to water infiltration within the manhole.
  • Figure 6 is a view similar to Figure 4 where the liner has cured.
  • Figure 7 is a perspective view of a sealing member in accordance with a second embodiment of the present invention where at least a portion of the proximal end of the sealing member includes a flange portion.
  • the sealing member 10 should be less than about 10 mm in thickness, with 2-3 mm most preferred.
  • the sleeve is preferably produced directly in the form of a tube.
  • alternative constructions of a tube are possible, such as where a sheet of material is formed into a tube and fused together by thermal bonding, sewing, adhesives, or other mechanical bonding methods.
  • the sealing member 10 may be formed by taking a sheet of material and forming it into a tube by overlapping the ends, and then securing the tubular form within the pipe. Therefore, a bonded, continuous tube is not required to practice this invention.
  • the body 16 preferably comprises a generally uniform wall thickness along the length of the sealing member.
  • the sealing member 10 may have a non-tubular or otherwise irregular configuration.
  • Figure 2 is a sectional view of an embodiment of the sealing member 10 while placed in a strained conformation.
  • the sealing member 10 includes a strained portion 20 along the length of the sealing member that allows the outer profile of the sealing member 10 to be reduced, allowing an easier insertion of the sealing member 10 into the pipe.
  • Figure 3B is a sectional view of the sealing member 10 and mechanical fastener 18 of Figure 3 A within a pipe 32.
  • Figure 3B shows the use of a circular, cylinder shaped mechanical fastener 18 placed near an end of the sealing member 10. While the length of the mechanical fastener 18 is shown to be substantially less than the length of the sealing member 10, it should be appreciated that the length of the fastener 18 could be the same or even longer than the length of the sleeve 10. In addition, it should be noted that when using a fastener such as shown in Figure 3B, it should be of minimal thickness to avoid blockage. The thickness of the mechanical fastener 18 in this and all the figures is exaggerated to show placement and structure of the component.
  • sealing member 10 is placed into the main pipe 32 such that the proximal end 12 of the sealing member 10 is adjacent the main pipe/manhole junction 36. Additionally, a mechanical fastener 18 is shown near distal end 14 of sealing member 10. After the sealing member 10 is placed into the main pipe 32, the sealing member 10 is allowed to expand back into its initial tubular conformation. The elasticity of the sleeve 10 will cause the sleeve to revert from the strained conformation to the initial tubular conformation to fit the sleeve 10 against the wall of the main pipe 32. The sealing member 10 is secured against the wall of the main pipe 32 using the mechanical fastener 18.
  • additional sealing members 160, 164, 168, 172 may be placed into the manhole 130 before placement of the manhole liner 150.
  • the manhole liner 150 is placed against an inner wall or portion of the sealing member(s), the resinous material of the manhole liner is allowed to cure and harden, and any infiltration from the manhole is then staunched by the sealing member(s) placed between the manhole liner and manhole at areas prone to water infiltration or leakage.
  • an advantage of using an additional sealing member at the manhole casting is that the sealing member will provide a cushion to the cured manhole liner for freeze-thaw cycles, as the manhole casting is susceptible to expansion and contraction due to the elements.
  • the primary advantage of using additional sealing members at the junctions of the bottom pan, the barrel, the cone, and the adjusting rings is that most points of water and sediment infiltration/exfiltration are sealed using the sealing members.
  • another point of water and sediment infiltration/exfiltration within the sewer system is the junctions of main and service pipes.
  • the assembly may further include a service liner to seal the service pipes.
  • the use of a service liner is optionally considered for use with some embodiments of the present invention.
  • An optional feature of the embodiments of the present invention includes adding an adhesive to the outer wall of one or all of the sealing members.
  • the adhesive may cover at least a portion of the outer wall, to assist in holding the sealing member within the main pipe, manhole, or other structure.
  • Types of adhesives for use with the present invention include but are not limited to pressure-sensitive adhesives, double-sided tapes, or adhesive foams. It is preferred to include a paper or polymeric backing onto the adhesive, so that an installer may quickly peel the backing, insert the sealing member into the pipe, manhole, or other structure, and press the adhesive against the pipe or manhole.
  • a sealing member having a flange portion may be secured to a main pipe/manhole junction by including the adhesive on the flange portion of the sealing member that abuts the wall of the manhole.

Abstract

L'invention concerne un appareil et un procédé d'étanchéité de tuyaux ou de structures souterraines. Dans un premier mode de réalisation, l'extrémité d'un tuyau est scellée de façon étanche par l'utilisation d'un revêtement de tuyau (140) et d'un élément d'étanchéité (110). L'élément d'étanchéité peut être un matériau hydrophile, un matériau hydrophobe, un matériau compressible ou une pâte. L'élément d'étanchéité est maintenu en place par un organe de fixation mécanique et un revêtement est installé de façon adjacente à l'élément d'étanchéité et contre la paroi du tuyau ou d'une autre structure à sceller de façon étanche. Dans un autre mode de réalisation, un regard est scellé de façon étanche par l'utilisation d'un élément d'étanchéité, d'un organe de fixation mécanique et d'un revêtement de regard.
