| titleOfInvention |
Method and device for the mechanical cleaning of well shaft walls, pipelines or gravel layers behind a well shaft wall |
| abstract |
The method involves gas or compressed air with a fine distribution before the outlet from the high pressure nozzle being added to highly pressurised cleaning fluid. This fluid emerges from a stationary or rotating nozzle arrangement (5) with at least one high pressure nozzle (6,7) in the working area of the manhole shaft or pipe. The water portion of the mixture is greater than the air or gas portion. The gas or air pressure is adapted to the static pressure in the working area and added to the fluid jet at an approximate pressure of 50-350 bar. |
