FRANKIPILE
High Pile Loads
Optimum Adaptation to Foundation Soil
Low-noise Manufacturing Process
The FRANKIPILE
Application possibilities
The FRANKIPILE can be used in a wide range of foundation
soil conditions as a deep foundation element for all types of
constructions such as, e.g. bridges, roads, tunnels, industrial
and office buildings, dock bases, craneways, wind power plants
and many more. It offers particular advantages in places where
high loads have to be transferred or where good, load-bearing
foundation soil only occurs very deep down in the ground.
Where very high loads have to be transferred in restricted areas,
a further development is available in the form of the Megapile,
which enables pile loads of up to R2,K = 6000 kN, depending
on the foundation soil (see separate brochure). The pile system
has a wide variety of designs enabling it to be ideally adapted
individually to the various types of foundation soil conditions and
building site situations.
Vertical piles as well as sloping piles tilted up to 4:1 are available.
Due to its base expansion the FRANKIPILE is also well suited to
absorbing tensile loads.
The dimensioning and the manufacturing of the FRANKIPILE
are carried out according to DIN 1054 and DIN EN 12699. For
preliminary dimensioning, dimensioning curves are given for
the FRANKIPILE in the “EA piles” for both non-cohesive and
cohesive soils.
Manufacturing process
The FRANKIPILE is a cast-in situ concrete foundation pile with a
recovered driving pipe. This is closed watertight underneath by
means of a stopper made of dry concrete or grit. A free fall pile
hammer working in the pipe strikes onto this stopper, thereby
driving the pipe into the ground.
The resulting pile driving work (number of strikes/m) is a measure
of the load-bearing capacity of the ground at the respective
pile location. After reaching the target depth and the pile driving
criteria respectively, the stopper is detached and the necessary
base concrete quantity is rammed down. Finally a reinforcing
cage is adjusted, concrete filled in and the driving pipe pulled up
again.
Should the in-situ ground have insufficient load-bearing capacity at the intended settling depth, ground improvement can
be carried out before manufacturing the pile base by means of
gravel pre-compression. In this case the ground is improved in a
corresponding area below and above the pile settling depth by
means of ramming down gravel.
Environmental friendliness
The manufacturing of the FRANKIPILE takes place with low
emissions due to internal pile driving. In the case of favourable
boundary conditions it is also possible to carry out the foundation work with this pile system in the proximity of existing
buildings. Due to the full earth displacement it is not necessary
to transport earth, this therefore excludes the earth becoming
loosened.
The pile system has proven itself many times in building projects
on contaminated sites.
Economic efficiency
The specific adaptation of the possible design variations to the
foundation soil and the building site situation result in optimum
utilisation with regard to the load-bearing capacity and pile
length. Its almost 100-year application in building works is based
on its perfected technology, high manufacturing standards and
excellent economic efficiency.
