Device for renovating damaged line walls, comprising a heating device for quickly curing the renovation compound

A method for rehabilitating damaged pipe walls in the region of the connection of a secondary pipe to a main pipe, comprising the following steps, in the following sequence:

• a) providing an apparatus for rehabilitating damaged pipe walls in a region of a connection between a secondary pipe and a main pipe, the apparatus comprising a mobile carrier element including a covering element and an expandable expansion body arranged on the carrier element, wherein the expandable expansion body, when not expanded, is positionable at least partially in a first recess of the covering element and at least partially in the secondary pipe, wherein the expandable expansion body when expanded, lies against the wall of the secondary pipe such that the covering element and the expansion body together form a shuttering, and wherein the covering element includes a second recess through which a viscous, curable rehabilitation compound can be introduced by a transport means from a storage device into a space defined between the shuttering and walls of the main and secondary pipe adjacent to the shuttering;
• and a heating device which is at least one of integrated in the storage device or operatively connected to the storage device;
• b) moving the carrier element to the region to be rehabilitated;
• c) expanding the covering element until it lies against the inner wall of the main pipe;
• d) positioning the expansion body by means of the first recess of the covering element;
• e) expanding the expansion body;
• f) positioning the transport means on the second recess of the covering element;
• g) heating the covering element and/or the transport means before, during and/or after transporting the rehabilitation compound into the space between the shuttering and the walls of the main and secondary pipe adjacent to the shuttering.
