Abstract (en)

[origin: EP1555388A1] The method involves dismantling soils such as stable soils where a drilling starting point is defined rotating around a longitudinal axis and pushed forward into the soil (6). Fluid (5) under high pressure loosens the soil where it can be released and pulled. Drilling start points are defined which indicate a starting point for the soil to be dismantled.
