The Importance
of Data Recording
and Analysis
Can you tell the load-bearing capacity of a driven pile by
Why piling work is not just about driving a pile into the ground
just looking at the top of it? Is there any way of seeing
what energy was needed to drive it into the ground?
Can you see if a pile has been damaged by impact energy, just by
looking at the surface? Is there any way of reading the exact position
and inclination data?
All these questions probably have the same answer: precise
statements about the load-bearing capacity of an impact
driven pile cannot be made without appropriate data recording
and analysis.
The aim of qualitative pile driving is always the same: every
impact driven pile must achieve a certain driving depth and a
certain load-bearing capacity in order to bear the calculated loads
for a construction project. For this purpose, either a load-bearing
layer is achieved through using an adequately long pile, or sufficient
resistance is generated through skin friction combined with
toe resistance.
Accordingly, it is all about the resistance, i.e., the load-bearing
capacity of a pile, and therefore how these values can be calculated
and verified. As deep foundation experts, Liebherr has come up
with a combination of the most diverse machines, attachments
and assistance systems.
It all begins with the correct planning. The dimensions, number
and exact position of the driven piles are calculated based on
the object to be built and its load-bearing requirements. Liebherr
offers the right equipment for the most diverse requirements in
