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.

Punmia, Ashok Kumar Jain, B. This process is similar to ordinary driven cast-in-situ piles. Enlarged “Franki” base When the tube has been driven to the required depth, the casing is very slightly raised and maintained in position with the aid of steel cables.

Established in 1983 and Executed plenty big piling projects in Iraq

The old adage that building roads and bridges is fundamental to the growth of an economy has certainly been heeded by the Saldanha IDZ Industrial Development Zonewhich, in contrast to many areas in South Africa, has been undertaking fraanki infrastructural development with the funds they have received from the Western Cape government for that specific purpose.

Due to the compression of the concrete plug, a water-tight bottom plug is created which prevents pie or water from entering the casing.

The dry concrete plug was not introduced to the design until Successive charges of zero slump concrete are pilee into the soil, simultaneously withdrawing the feanki.

Bythe technique had been implemented by 34 international subsidiaries and license holders. Maximum lengths are of the order of 25 m, although the length usually used is less than 20 m. The composite Franki pile is installed when it is difficult or not suitable to cast the pile shaft in situ. The Yacht Club, a … Read More. Geotechnical work in the marine environment demands creative solutions to complex challenges.


In addition, the pile is also suitable for the adsorption of tensile loads due to its widened base. The raked shafts are always reinforced over their whole length.

The concrete tranki rammed with a 2 to 4 ton hammer while the tube is kept in position by steel cables. The construction of each Franki Pile is molded to the ground conditions at each pile location, and can frahki withstand very high compressive and tensile forces and substantial horizontal loads. Among the important skills required to wear this crown, especially in these times of challenging economic conditions, are the abilities to reconfigure original … Read More.

Franki Piles is a driven, enlarged base, cast in-situ pile that can be constructed in practically pils soil conditions. For the prestigious new Umhlanga Arch development, north of … Read More. Among the important skills required to wear this crown, especially in these times of challenging economic conditions, are the abilities to reconfigure original ….

The concrete of the shaft is compacted using the drop hammer, the diameter of which is smaller than that of the reinforcement. Established in and Executed plenty big piling projects in Franli.

The Franki piling system also called pressure -injected footing is a method used to drive expanded base cast- in-situ concrete Franki piles. The pild displaces the concrete laterally into the soil previously compressed by the driving of the tube. Edgard Frankignoul applied for the production patent for the Franki pile in July 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 pille.

Alternatively, the steel casing can be installed by “top-driving”, using ordinary drop hammers. Views Read Edit View history. Characteristic pile loads up to 6, kN Franmi soil displacement Excellent resistance settling characteristics Additional soil improvement possible using gravel pre-compaction 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.

The diversity of the execution variations facilitates the individual adaptation to very different foundation soil conditions and construction site situations. Retrieved from ” https: One such project was the recently completed construction of a m-long oile wall with a draft of Bottom driving with an internal hammer.

Pile foundations in Engineering Practicep. In North America, the Franki system is known as pressure injected footing. For Keller company, Franki Africa, which is in the process of doing the geotechnical work, this prestigious project has been somewhat of a milestone.

This operation causes compression of the soil by lateral displacement. A special concrete bucket is used pule pour a certain amount of nearly dry concrete into the bottom of the driving tube. Alternatively, a pre-fabricated pile shaft can be used. Typical Franki pile dimensions range from 0. The reinforcing bars are tied by mm spirals at the pitch of 10 – 25 cm.

The expanded base of the pile is then formed by adding as much dry concrete as necessary to achieve a pre-determined “driving set”. In that case, the driving casing must be provided with a lost bottom plate.
