Application
- Particularly suitable for residential construction, commercial construction, and other new buildings where disturbance to the surrounding area needs to be limited.
- Suitable for urban renewal projects where vibration-free foundations near adjacent buildings or properties are required.
- An alternative to non-soil-displacing screw piles where excavated soil severely contaminates the construction site or cannot be removed or disposed of.
- Causes less noise disturbance than driven pile systems, making them applicable for the expansion of existing and occupied buildings.
- Applicable in soil conditions or loadings where a long reinforcement cage is necessary, which can be centrally placed in the pile with the required coverage.
Features
- Soil-displacing, with only limited excavated soil at the drilling tube and ground level.
- Low-vibration, therefore well-suited near adjacent structures sensitive to settlements and/or vibrations.
- Noise-friendly, resulting in less disturbance to the surroundings and suitable near residences, schools, public buildings, etc.
- Pile head is poured up to the working level.
- Pile length can be immediately adjusted to the ground conditions.
- Adjustments in pile specifications possible until just before work commencement.
- Batter positions: backward 5:1 / forward 10:1.
- Loadable both in tension and compression.
- Reinforcement possible along the entire length.
- Reinforcement is installed in the feed tube before concreting.
- The pile system is known and accepted by the Building and Housing Supervision service, structural engineers, as well as in construction standards. Competitive compared to soil-removing piles due to greater bearing capacity and a 'clean' construction site.
Vroom Funderingstechnieken has extensive experience with screw piles and provides advice on the application possibilities of this pile type and other screw pile systems.
Quality Control
Vroom Funderingstechnieken manufactures DPA-PLUS screw piles according to a procedure established for Vroom Funderingstechnieken as part of internal quality control, nationally applicable standards, and execution conditions.
Control of Geotechnical Bearing Capacity
DPA-PLUS screw piles are installed to the calculated screw-in depth during soundings. The required drilling moment is measured for assessment and recognition of the existing soil condition.
Control of Pile Technical Bearing Capacity
All DPA-PLUS screw piles are checked for continuity after pile manufacturing. Additional inspection can visually occur after excavation of the pile head. The concrete quality can additionally be checked by drilling and testing cores from the manufactured piles.
