Double Rotary Case Piles
- Restricted access
- Low headroom
- Challenging subsurface conditions
- Environments sensitive to noise or vibrations
The diagram below shows the standard procedure of casing installation, excavation, cleaning of the slurry; then installing the reinforcement cage, pouring the concrete and extracting the casing.
FDP are a type of reinforced concrete pile that are built in situ. This technology combines the advantages of driven (displacement piles) and bored piles (piles without displacement).
Despite being executed in situ, along with bored piles, they are classified as displacement piles due to the fact that, throughout its execution, it exists the soil consolidation around the pile, as a result of an horizontal displacement imposed 2 by the drilling equipment. This compaction intends to improve the soil characteristics thus increasing the available area at the time of the loading application.
This technique uses a specific drilling equipment which is inserted in the soil by virtue of the application of a torsional movement, applied in the auger rod, and a downward thrust. The main difference between this technique and the remaining techniques is the drilling tool configuration that causes an horizontal displacement during the drilling process due to a zone with a greater diameter.
- Very low levels of sound and vibration.
- Compared to conventional bored piles they can be installed very quickly and economically.
- They have high load-bearing, shear and movement capacities.
- They are suitable for a wide range of challenging ground conditions
- Piling rigs can be adapted to operate in conditions with low headroom and confined space
Ausipile can drill up to 2.8 meter in diameter and up to 68 meters deep if required in ideal conditions if required please feel free to contact our team at Ausipile to see what will best fill your needs.
- Boring without bentonite support
- Allowing the jobsite installation plant to be minimized
- No vibration or impulse during construction
- Increase in productivity
- Rock drilling up to resistance of 8o MPa (unconfined compressive strength-UCS)
