    摘要: A device for conduit sealing and repair is taught. Briefly stated, a cable or conduit is passed through an opening in a foundation or bulk head enclosure. A substantially cylindrical collar which is longitudinally split into two portions is placed onto the conduit with the conduit and collars then placed into the enclosure opening. An expandable foam is injected into an opening in the collar which, when expanded forces apart the two portions thereby snuggly fitting the collar into the opening. The foam is also allowed to exit through openings in the collar and thereby fills any voids between the exterior of the collar and the interior portion of the opening and which thereby forms a water tight as well as gas tight seal. Reentry into the opening for removal and/or replacement of the conduit is accomplished by pulling on stainless steel strap which are positioned in openings and around portions of the collar. Therefore the removal of the collar as well as the foam which is inside and outside of the collar is easily accomplished.
