DEVICE FOR RENOVATING DAMAGED LINE WALLS, COMPRISING A HEATING DEVICE FOR QUICKLY CURING THE RENOVATION COMPOUND

摘要

The invention relates to a device (1) for renovating damaged line walls in the region of the connection of an auxiliary line to a main line, comprising a movable support element, wherein a cover element (3) and an expandable element (5) are arranged on the support element. In the non-expanded state, the expandable element is positioned or can be positioned in the auxiliary line at least partly in or through a first recess (7) in the cover element, and in the expanded state, the expandable element lies against the wall of the auxiliary line such that the cover element and the expandable element together form a shell. The cover element has a second recess (11), through which a curable viscous renovation compound can be introduced from a storage device into the space between the shell and the main and auxiliary line walls adjoining the shell by means of a transport means. The device comprises a heating device which is integrated into the cover element, the storage device, and/or the transport means at least in the region of the second recess and/or is operatively connected to the cover element, the storage device, and/or the transport means at least in the region of the second recess.
