A method for mounting a marker to a specific area in a pipeline and/or sewer system, wherein an inspection and/or maintenance system in the pipe-line and/or sewer system is brought into the region of the specific area, and the inspection and/or maintenance system mounts the marker to the specific area, wherein the marker comprises an RFID transponder, is provided. A method for detecting a marker in a pipeline and/or sewer system, a method for renovating a portion of a pipeline or sewer system, and devices for mounting the marker at the predetermined area in the sewer and for detecting the mounted marker are also provided.

The invention relates to a clearing device for the rehabilitation of a pipeline, especially for clearing a branching-off in a pipeline system rehabilitated by means of a tubular liner, comprising at least one clearing device, which is movably mounted by at least one degree of freedom, and a slope sensor located on the clearing device.

The present invention relates to an apparatus and a system for curing a liner extending in a pipeline or at least in part in a branch pipeline, where the liner includes a substance such as a synthetic resin suitable for being curable by exposure to electromagnetic radiation. The apparatus comprises an actuator constituting an electric, hydraulic or pneumatic actuator, and including an actuator member and an actuator axis substantially parallel to the axis of the pipeline when said apparatus is in its intended operational position in said main pipeline. The apparatus also comprises a light head having a light source for emitting electromagnetic radiation for curing said substance, and connected to the actuator member, where the actuator and actuator member are configured for applying a force to the light head in a direction substantially parallel to the actuator axis for displacement of the light head, such that the substance being cured as the light head moves through the pipeline and exposing the substance to electromagnetic radiation.
