Dynamic load test in Cologne
Drop weight up to 12 t, evaluation per CAPWAP. For Cologne, Bonn and the Rhineland, with own measurement technology and travel distance about 3.5 hours from Gotha.
What the test delivers.
Bearing capacity of several piles within one day, evaluated per CAPWAP. The method per DIN EN ISO 22477-4 delivers shaft friction and base resistance separately and fits where the construction schedule does not allow a week of setup.
Details on the method are on the service page Dynamic load test.
Rhenish terrace gravel over tertiary sands and clays, in the surrounding area loess and lignite open-pit mining with dumps and large-scale groundwater lowering. Rising groundwater changes the stresses in the ground over decades.
On dumps and in lowering cones, experience values are worthless because the ground no longer has a naturally grown profile. Settlement occurs there with delay, often years after acceptance.
Dynamic load test in four steps.
- Expose pile heads, apply transducers
- Series of blows with drop weight, measure force and velocity
- CAPWAP model analysis, separation of shaft and base
- Report with bearing capacity and assessment per EA-Pfähle
The structural engineer gets numbers instead of assumptions. Measured bearing capacity allows a proof per Eurocode 7 without blanket safety margins.
Cologne, Bonn and the Rhineland is geologically inconsistent. The test shows what the pile carries at exactly this spot, not what the ground model would suggest.
Differential settlement causes cracks, tilting and re-foundation. Tested piles are the cheapest part of structural stability.
