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.
