ABSTRACT:
A process and device for decontamination of contaminated soil wherein contaminated soil is precleansed by a pressurized flushing and cutting jet of a cutting device located in a borehole. The soil is removed from the existing soil structure and flushed so intensely that is largely freed from adhering pollutants. The fine particles of the flushed and precleansed soil, together with the pollutants, are sluiced as a slurry in a return flow through a preventer. For decontamination, they are conveyed to a decontamination plant where the remaining pollutants are extracted. The coarse particles of soil remain in the ground. Finally, the cleansed soil, together with a bonding agent, is flushed back into the borehole where it forms a soil structure capable of bearing loads.
