Zusammenfassung:	PCT No. PCT/BE94/00078 Sec. 371 Date Jun. 17, 1996 Sec. 102(e) Date Jun. 17, 1996 PCT Filed Oct. 28, 1994 PCT Pub. No. WO95/12050 PCT Pub. Date May 4, 1995Soil displacement auger head for installing piles in the soil, having a tip, a displacement body having at least over a lower portion a core diameter increasing in diameter in a direction away from the tip, and at least one screw flange extending at least over the lower portion of the displacement body. To obtain a more efficient displacement, the pitch of the screw flange increases and the core diameter of the displacement body increases preferably discontinuously via a number of transition slopes.
