Simplex pile - FRANKI Grundbau

Simplexpile
Full soil removal
High cost-effectiveness
The Simplexpile
Possible applications
The FRANKI Simplexpile is a low-cost driven
cast-in-place concrete foundation pile. It can
be used in every case where vibrations and
noise emissions are not a decisive criterion.
It can be employed as a deep foundation element for construction works of all types, such
as e.g. logistics centers, industrial buildings,
crane tracks, wind energy systems and many
others.
The Simplexpile can be equipped with polyester pipes so that the pile can also be used as
an energy pile. With energy piles, geothermal
heat can be used for the heating and cooling
of buildings.
Vertical piles as well as sloping piles tilted up to
4:1 are available.
The dimensioning and the manufacturing of
Simplexpiles is implemented in accordance
with DIN 1054 and DIN EN 12699.
Building practice
PCH Packing Center Hamburg, Wollkämmereistrasse, Hamburg: 1.400 Simplex piles
Manufacturing process
The Simplexpile is a cast-in-place concrete
foundation pile with recoverable driving pipe.
This is closed off watertight below with a base
plate. A hydraulic and diesel ram drives the
pipe into the ground by means of head piledriving.
The pile-driving work performed in this case
(number of impacts/m) is a measure for the
load-bearing capacity of the ground at the
respective pile location. On reaching the
setpoint depth and/or the pile-driving criteria,
a reinforcement cage is adjusted into place,
filled with concrete and the advance pipe is
extracted again, where the base plate remains
in the ground in this case.
Environment friendliness
Due to vibrations and the noise emission, the
pile system can be employed only with restrictions in case of neighboring developments.
Because of the full soil displacement, the
removal of ground is dispensed with and loosening of the ground is thus excluded.
The pile system has proved itself many times
with projects in contaminated locations.
Construction of a new factory in southern Germany: 2.500 Simplex piles
Cost-effectiveness
Due to the short manufacture time with corresponding boundary conditions, the Simplexpile
is particularly suitable for foundations with a
large pile item number, as well as specified
large binding lengths in the load-bearing foundation soil.
For the manufacture of the Simplexpiles KC
pile-driving systems are available to FRANKI
Grundbau with a possible pile-driving depth up
to 43.5 m and Junttan hydraulic rams with a
fall weight of 140 kN.
