Abstract (en)

[origin: WO9906639A1] A method of ground reinforcement uses a screw-in anchor element (16) which has a shaft (17), helical flight (18) adjacent a leading end, a helical flight (19) adjacent a trailing end, and a drive coupling (20). The anchor element is screwed into the ground with the leading end placed in relatively stable soil and the trailing end placed in relatively unstable soil. The flight (18) may be of greater pitch than the flight (19). The shaft (17) may be hollow. When the shaft (17) is hollow, it may be used to drain liquids or gases from the soil, or to introduce active agents to treat polluted ground.
