Device, useful for sealing a pipe to a breakthrough in a wall section, comprises a sealing body comprising a through opening for a passage of pipe, and a sealing material that is arranged between the sealing body and the pipe

摘要

The device comprises a sealing body (2) comprising a through opening for a passage of pipe, and a sealing material (4) that is arranged between the sealing body and the pipe, is present in an inactive state at recesses (6) of the sealing body and is movable in an active flowable state to fill an interstice between the sealing body and the pipe. The sealing material in the inactive state is stable by a protecting layer, and is movable by the removal of protecting layer into the active state. The protecting layer comprises a gripping section that is arranged outside of the sealing body. The device comprises a sealing body (2) comprising a through opening for a passage of pipe, and a sealing material (4) that is arranged between the sealing body and the pipe, is present in an inactive state at recesses (6) of the sealing body and is movable in an active flowable state to fill an interstice between the sealing body and the pipe. The sealing material in the inactive state is stable by a protecting layer, and is movable by the removal of protecting layer into the active state. The protecting layer comprises a gripping section that is arranged outside of the sealing body. The recess is arranged at a surface of the sealing body limiting the through opening. The device further comprises a bracing device (8) by which the sealing body is axially compressable and the sealing material is movable into the active state. The bracing device comprises two chip boards, and clamping screws. A cross-section of the recesses has a central axis of the sealing body towards increasing width in an axial direction. The recesses are spaced and parallel to each other arranged in axial direction of the sealing body, and are formed circumferentially about the central axis of the sealing body. The recesses are formed as lips wider than a wave trough of a corrugated pipe or a partition wall between the recesses, where the lips extend to a bottom of the wave trough. The sealing material in the inactive state is torically formed, is arranged along the whole length of the recesses, and extends over a partial section of the recess. The sealing material: is arranged spaced to each other along the recess; is adhered with the sealing body and/or the pipe; is formed as a reactive material so that the sealing material is hardened in the active state; and comprises single-or multi-component materials having duration-plastic such as butyl rubber and/or curing behavior. The sealing body comprises a passage by which a flow connection is produced between the recess of the sealing body and a peripheral surface of the sealing body to fill the interstice between the breakthrough and the sealing body. A total volume of the sealing material arranged in the recess in the active state is equal to or greater than the volume of the interstices to be filled.
