Abstract

The invention relates to a sewer rehabilitation method, wherein a rehabilitation tool (5) is introduced, by means of a robot (2) that can be moved in a sewer main line (3) of a sewerage system, into a house sewer line (9) leading into said sewer main line (3), rehabilitation work is carried out in the house sewer line (9) by means of the rehabilitation tool (5), and the rehabilitation tool (5) is removed from the house sewer line (9) by means of the robot (2) once rehabilitation work is completed. The aim of the invention is to provide a viable and cost-effective sewer rehabilitation method and corresponding system enabling sewer rehabilitation work being carried out in the house sewer line (9) starting from the sewer main line (3). For this purpose, the robot (2) picks up the rehabilitation tool (5) and transports it through the sewer main line (3) to the mouth of the house sewer line (9), introduces the rehabilitation tool (5) into the house sewer line (9) and puts it down, advances the rehabilitation tool (5) in the house sewer line (9) up to a defective point (10) and retracts the tool from the house sewer line (9) and picks it up again once rehabilitation work is completed. The invention further relates to a sewer rehabilitation system comprising a robot (2) that can be moved in a sewer main line (3) of a sewerage system and a rehabilitation tool (5) that can be introduced into a house sewer line (9), the robot (2) having a remotely controllable gripping member (4) with which the rehabilitation tool (5) can be gripped.
