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.

In that case, the driving casing must be provided with a lost bottom plate. 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 dry concrete plug plie not introduced to the design until Edgard Frankignoul applied for the production patent for the Franki pile in July The casing can frranki be installed using a large-stem auger VB-pile.

This process is similar fanki ordinary driven cast-in-situ piles. Geotechnical engineering Civil engineering Foundations buildings and structures. By using this site, you agree to the Terms of Use and Privacy Policy. For piles subject to uplift forces, the reinforcement is anchored in the enlarged base, thus providing high pull-out resistance.

Franki Pile – Al-Saba Concrete Piles Co. Ltd.

Characteristic pile loads up to 6, kN Full 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. 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 raked shafts are always reinforced over their whole length.

The pile shaft can also be made frankj “wet concrete”, which speeds up the construction process. The expanded base of the pile is then formed by adding as much dry concrete as necessary to achieve a pre-determined “driving set”. This negative friction is sometimes encountered in non-compressible soils. The Yacht Club, a … Read More.

The Franki pile, known and used worldwide, was developed at the turn of the century by the Ppile engineer Frankignoul. Alternatively, the steel casing can be installed by “top-driving”, using ordinary drop hammers.

For the prestigious new Umhlanga Arch development, north of … Read More. It takes business acumen, customer service excellence, team-building skills, and a whole lot more. plle

The Franki pile process has undergone several reformations since it was conceived. Through the targeted adaptation of the possible execution versions on the foundation soil and the construction site situation, optimised exploitation can frankki achieved with regard to the load capacity and pile length.

They can withstand dynamic stresses and are particularly suitable foundations for structures containing machines and subject to dynamic forces.

Among the important skills required to wear this crown, especially in these times of challenging economic conditions, are the abilities to reconfigure original …. Punmia, Ashok Kumar Granki, B. Typical Franki pile dimensions range from 0. This hammer can be dropped from granki height of several meters. A special piel bucket is used to pour a certain amount of nearly dry concrete into the bottom of the driving tube.

Franki piles can be used as high-capacity deep foundation elements without the necessity of excavation or dewatering. Bottom driving with an internal hammer. Due to the ramming process, the concrete is in close contact with the soil and in this way a cylindrical shaft is obtained, which is resting on an enlarged base, formed to refusal in the bearing layer. The shaft of the pile is formed by ramming successive layers of “dry concrete”, raising the casing 0.

Franki shafts may be installed raked.

Franki Foundations – Franki pile

By expulsion of a dry concrete plug, the soil surrounding the pile base is improved and thus the initial soil bearing capacity can be increased significantly. Retrieved from ” https: 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. This operation causes compression of the soil by lateral displacement.

By adopting some additional measures, the effects of negative friction may be cancelled. For the prestigious new Umhlanga Arch development, north of …. Successive charges of zero slump concrete are rammed into the soil, simultaneously withdrawing the tube.

The construction of each Franki Pile is molded to the ground conditions at each pile location, and can safely withstand very high compressive and tensile forces and substantial horizontal loads.

People struggle to make a living in Tugela Ferry and the harsh conditions …. The old oile 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 significant infrastructural development with the frqnki they have received from the Western Cape government for that specific purpose.

Both vertical piles and inclined piles can be executed tilted up to 4: One such project was the recently completed construction of a m-long quay wall with a draft of It requires only a minimum of site preparation and in some particular cases, e. Concreting of the shaft. B ridge structures Wind power plants Crane tracks Dock bases Industrial buildings Heavy-duty surfaces and much more.

Such a cased shaft eliminates the curing time required for the concrete precast pile. It is interesting that in both the below marine projects, one of the common themes is great teamwork … Read More.

It is interesting that in both the below marine projects, one of the common themes rranki great teamwork pilr. The reinforcing bars are tied by mm spirals at the pitch of 10 – 25 cm. A thick-walled steel casing is placed vertically on the ground. In North America, the Franki system is known as pressure injected footing. 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.
