The Technological Center for New Developments in Trenchless Technologies offers elimination of local defects and imperfections (unevenness and pores) in pipelines by means of remote-controlled robot-cutter. The machine is used for removing of obstacles from pipes with inside diameter from DN 200 mm to DN 600 mm; it is also suitable for opening of lateral connections after the rehabilitation.
The robot is remotely controlled from the surface; by means of an in-built colour camera the operator receives on a monitor detailed information about the size and the exact position of the obstacle and implements its removal. The image from the camera is recorded on a DVD as video material and is a compulsory component of the Protocol for the implemented work.
