Concrete piles for introduction into the ground, as well as of a plurality of such piles produced by foundations and, if appropriate, foundation image, as well as devices for the introduction of the concrete piles
The piles (1) are vibrated to and fro in their longitudinal direction (A-B), and thereby driven into the ground (2) until a position is reached, which is slightly short of their final position. Vibrations cease, and a traction or pressure force without vibrations is applied to the piles, until these are held in the ground with slight prestress. The piles decrease in size conically downwards, and have square, rectangular, oval or elliptical cross section. They consist of a porous concrete material and are hollow. Each pile has a top section (8) with a holder, which is accessible from above, for a vibrator. The piles are from 8 m. to 12 m. long.
