FRANKI PILE PDF

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.

Among the important skills required to wear this crown, especially in these times of challenging economic conditions, are the abilities to reconfigure original …. Frabki of this piel Read More. It requires only a minimum of site preparation and in some particular cases, e. Alternatively, a pre-fabricated pile shaft can be used. As Managing Director Errol Braithwaite says: For Keller company, Franki Africa, which is in the process of doing the geotechnical work, this prestigious project has been somewhat of a milestone.

It is interesting that in both the below marine projects, one of the common themes is great teamwork …. People struggle to make a living in Tugela Ferry and the harsh conditions …. Some of this …. One such project was the recently completed construction of a m-long quay wall with a draft of 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.

The concrete is pille with a 2 to 4 ton hammer while the tube is kept in position by steel cables. An octagonal or circular pile, made of precast reinforced concrete or pre stressed concrete, is sunk into the tube and securely anchored on the base by means of some blows the hammer. Bythe technique had been implemented franmi 34 dranki subsidiaries and license holders.

Established in and Executed plenty big piling projects in Iraq. For the prestigious new Umhlanga Arch development, north of …. The plug is then expelled by heavy blows of the hammer, making sure that a certain amount of rammed concrete remains in the casing ppile order to prevent any seepage of water or soil into the pile shaft.

Franki Foundations – Franki pile

This process is similar to ordinary driven cast-in-situ piles. The Yacht Club, a …. The outside diameter of the cage varies according ;ile the size of the tube being used. A thick-walled steel casing is placed vertically on the ground. The Franki piling system also called pressure -injected footing is a method used to drive expanded base cast- in-situ concrete Franki piles.

Franki piling system

The raked shafts are always reinforced over their whole length. In that case, a pre-fabricated shaft steel or concrete is installed after the expanded base has been constructed in the ordinary way. 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.

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 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.

Pile foundations in Engineering Practicep. This operation is checked with marks made on the driving cable of the hammer and on the lifting cables. People struggle to make a living in Tugela Ferry and the harsh conditions … Read More.

From Wikipedia, the free encyclopedia. Typical Franki pile dimensions range from 0.

The Franki pile may be vertical or raked and pilr bearing capacity varies with the diameter of the pile base and the driving tube being used, which can be changed to suitable loads specified. By using this site, you agree to the Terms of Use and Privacy Policy. They can withstand dynamic stresses and are particularly suitable foundations for structures containing machines and subject to dynamic forces. Edgard Frankignoul applied for the production patent for the Franki pile in July 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.

Characteristic pile loads up to 6, kN Full soil displacement Excellent resistance settling characteristics Fganki soil improvement possible using gravel pre-compaction KVV Limitation of pioe 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 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. The dry concrete plug was not introduced to the frranki until It takes business acumen, granki service excellence, team-building skills, and a whole lot more.

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 significant infrastructural development with the funds they have received from the Western Cape government for that specific purpose. This page was last edited on 6 Octoberat Bottom driving with an internal hammer. Due to the compression fdanki the concrete plug, a water-tight bottom plug is created which prevents soil or water from entering the casing.

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 pike load capacity and pile length. Punmia, Ashok Kumar Jain, B. The shaft of the pile is formed by ramming successive layers of “dry concrete”, raising the casing 0.

In that case, the driving casing must be provided with a lost bottom plate.
