The arrangement has a pipe packer (10) with an inflatable seal (12) for the main sewer (16), a lateral seal (18) protruding from it in the inflated state for the connecting channel (24) and a tunnel (56) running from an axial end region of the packer seal in an inner volume bounded by it to a collar region for accommodating a feed line (58) for sealing material. |
