The Franki pile is a driven, cast-in-situ concrete displacement pile with an enlarged base in dry concrete and a cylindrical shaft. Dulce Simoes 7th December Piling. It takes more than the highest levels of ground engineering expertise and experience to be Keller’s Franki Africa. FRANKI DRIVEN CAST-IN-SITU PILES (DCIS). The Franki pile has been used extensively throughout Southern Africa for over 65 years and is still today one of.

Under its impact the concrete forms a plug at fganki bottom of the casing which penetrates slightly into the soil. Pile foundations in Engineering Practicep. Characteristic pile loads frnki to 6, kN Full soil displacement Excellent resistance settling frajki Additional soil improvement possible using gravel fanki KVV Limitation of settling depth Low noise emission in comparison to head ramming Reduction in the number of piles and foundation dimensions Highly economical due to reductions in concrete and steel quantities.

Concreting of the shaft. Successive charges of zero slump concrete are rammed into the soil, simultaneously withdrawing the tube. The pile shaft can also be made of “wet concrete”, which speeds up the construction process. For the prestigious new Umhlanga Arch development, north of ….

This hammer can be dropped from a height of several meters. Geotechnical engineering Civil engineering Foundations buildings and structures. It is interesting that in both the below marine projects, one of the common themes is great teamwork …. It is a cast-in-situ concrete pile with an enlarged base and a cylindrical shaft which, due to its powerful driving method during installation, can penetrate stiff soils and reach large depths.

In that case, ffanki pre-fabricated shaft steel or concrete is frxnki after the expanded base has been constructed in the ordinary way. For Keller company, Franki Africa, which is in the process of doing the geotechnical work, this prestigious project has been somewhat of a milestone.


The Franki pile process has undergone several reformations since it was conceived. From a geotechnical perspective, the complete overhaul of the Village Walk site has been sufficiently challenging for Franki project manager Paulo Alves to say that this was one of the most incredible projects he has ever worked on.

In North America, the Franki system is known as pressure injected footing. Franki Africa Frankipart of the Keller group, has developed a reputation throughout Africa for its innovative and cost-effective solutions for geotechnical work in the marine environment.

The expanded base of the pile is then formed by adding as much dry concrete as necessary to achieve a pre-determined “driving set”. The casing can also be installed using a large-stem auger Pike. Due to the compression of the concrete plug, a water-tight bottom plug is created which prevents soil or water from entering the casing. The composite Franki pile is installed when it is difficult or not suitable to cast the pile shaft in situ.

This method can be applied to different site conditions and is still widely used [2] [3] [4] due to its high tensile load capacity, and relatively low noise and ground vibration levels.

This process is similar to ordinary driven cast-in-situ piles. The use of this product in the building industry for over years is due to its sophisticated technology, the high standards of execution and the outstanding economic viability. Typical Franki pile dimensions range from 0. Introduction For construction programmes to be compressed into the shortest possible time to meet client handover deadlines is not unusual, but for contractors to offer innovative improvements to design to realise cost and time savings is far more so — particularly when this increases the pressure on the contractor to perform!


Through the targeted adaptation of the possible execution versions on the foundation soil and the construction site situation, optimised exploitation can be achieved with regard to the load capacity and pile length. Such a cased shaft eliminates the curing time required for the concrete precast pile.

A special concrete bucket is used to pour a certain amount of nearly dry concrete into the bottom of the driving tube. Bottom driving with an internal hammer.

The Yacht Club, a …. One such project was the recently completed construction of a m-long quay wall with a draft of The raked shafts are always reinforced over their whole length. As Managing Director Errol Braithwaite says: The shaft of the pile is formed by ramming successive layers of “dry concrete”, raising the casing 0.

It takes business acumen, customer service excellence, team-building skills, and a whole lot more. This operation is checked with marks made on the driving cable of the hammer and on the lifting cables. In addition, the pile is also suitable for the adsorption of tensile loads due to its widened base. Franki Piles is a driven, enlarged base, cast piel pile that can be constructed in practically all soil conditions.

For piles subject frankj uplift forces, the reinforcement is anchored in the enlarged base, thus providing high pull-out resistance. Some of this … Read More. Views Read Edit View history.
