Tunnel cleaning by Gruschina Transport and Rental GmbH was specially designed for the quick and thorough cleaning of all tunnels on all railway tracks.
The sequence of tunnel cleaning will be briefly explained to you in the following pictures.
COMPANY OWN CLEANING TRAIN
The improvement of our prototype has accomplished the following procedure: The washing, suction and brush unit will be mobile to transport, our own 2-way Unimogs with radio remote control and special wagons are provided as a work train including personel.
In one step, tunnel walls are cleaned with high pressure water and vacuumed (dry process, i.e. 97% of the liquids are captured), filtered by recycling plant (200l / min), recycled and fed into the water cycle. Thus, all set-up times have been minimized. A proof of disposal of the suction material is standard.
Powered by an electric-hydraulic unit emission and immission values are easily met eg. Subway tunnel.
A special pumping station in conjunction with its own water recycling plant and sludge tanks enable self-sufficient, continuous work.
At the same time, the railway line or fixed carriageway are cleaned with high-pressure nozzles and the liquid is sucked off.
All accompanying channels and cable ducts are provided with special brackets with washing brushes and suction device.
All air-encased concrete parts are cleaned with all built-in parts (power line, lighting, handrails), backwashing the drainage channels in the tunnel can run parallel as a third step.
