HIGH STRAIN DYNAMIC PILE TESTING
HIGH STRAIN DYNAMIC PILE TESTING
Quick, Cost Saving and Reliable. You Save Time, Money and Gain Quality Assurance
High strain dynamic pile test is perform using Pile Driving Analyzer (PDA) together with strain sensors and accelerometers. PDA is used to verify the mobilised capacity of all types of drilled and driven piles. Testing is conducted in a quick and non-destructive manner.
Dynamic measurements of force and velocity will be collected by the strain sensors and accelerometers attached to the pile. The PDA monitors the strain and acceleration caused by the hammer impact, and processes these signals after each hammer blow during driving or restrike to give immediate visual. The signals are digitised by PDA, results are computed, and the data array of the signals for a blow is stored.
- The following PDA results are typically obtained on site:
- Mobilised Static Load Capacity based on CASE method
- Pile Integrity – location and extent of damage
- Driving Stresses – maximum compression / tension forces at pile top / toe
- Hammer Performance – maximum energy transferred to pile
- Advantages of Dynamic Pile Testing:
- Instant preliminary results on site
- Instant check on pile integrity and location of any damage
- Feedback on maximum tension and compression forces
- Direct measurement of hammer input energy and efficiency
- Cost effective
