The Atlas pile is a vibration-free, cast-in-place concrete pile with double lateral soil displacement. The Atlas screw pile features virtual absence of any significant spoil and no decompression of soil around the auger tip. The lateral soil displacement and compaction effects as well as the particular helical screw shape of the concreted pile contribute to its high bearing resistance and stiff settlement behavior. Construction sequence 1. Implantation of the pile, placement of the lost, closing nut tip under the auger head, thus preventing the penetration of water and / or soil while screwing in. Correct positioning of the unique purpose built Atlas rig, whereby the axes of both the casing and the pile are aligned. 2. By means of a combined application of rotation and vertical forces, penetration into the soil of the steel casing and the especially designed Atlas auger head is obtained (screwing-in phase). 3. Once the required installation depth is reached and if required, full-length central reinforcement is placed into the steel tube prior to concreting. 4. & 5. During the reverse screwing-out phase, the Atlas screw is withdrawn at a controlled rate and concrete is poured through the hollow stem of the auger and the concrete funnel above it. The specific helical shape of the Atlas pile is formed during the upward movement of the auger: regular pile flanges cast continuously around the pile shaft. 6. The completed screw-shaped Atlas pile – If necessary, reinforcement cages are placed manually over the upper part of the pile, after the area of the newly concreted pile has been cleaned up (not shown on the scheme).
