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, lile driving casing must be provided with a lost bottom plate. This operation causes compression of the soil by lateral displacement.

From Wikipedia, the free encyclopedia. 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, known and used worldwide, was developed at the turn of the century by the Belgian engineer Frankignoul.

Frannki addition, the pile is also suitable for the adsorption of tensile loads due to its widened base.

Franki Piles (PIFs)

The shaft of the pile is formed by ramming successive layers of “dry concrete”, raising the casing 0. Maximum lengths are of the order of 25 m, although the length usually used is less than 20 m.

The expanded base of the pile is then formed by adding as much dry concrete as necessary to achieve a fganki “driving set”. Punmia, Ashok Kumar Jain, B. 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.

By adopting some additional measures, the effects of negative friction may be cancelled. Geotechnical engineering Civil engineering Foundations buildings and structures.

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. Among the important skills required to wear this crown, especially in these times of challenging economic conditions, are the abilities to reconfigure original ….

The reinforcing bars are tied by mm spirals at the pitch of 10 – 25 cm. Franki shafts may be installed raked. From a geotechnical perspective, the complete overhaul frankl 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.

One such project was the recently completed construction of a m-long quay wall with a draft of Franki piles can be used as high-capacity deep foundation elements without frnki necessity of excavation or dewatering. This method can be applied to different site conditions and is still widely used [2] [3] [4] due to its high tensile piile capacity, and relatively low noise and ground vibration levels. The hammer displaces the concrete laterally into the soil previously compressed by the driving of the tube.

Franki Piles | Hayward Baker

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!

The outside diameter of the cage varies according to the size of the tube being used.

The Franki pile process has undergone several reformations since it was conceived. In that case, a pre-fabricated shaft steel or concrete is installed after the expanded base has been constructed in the ordinary way.

Views Read Edit View history. Both vertical piles and inclined piles can be executed tilted up to 4: The casing can also be installed using a large-stem auger VB-pile. The Yacht Club, a …. The composite Franki pile is installed when it is difficult or not suitable to cast the pile shaft in situ. 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 frajki due to reductions in concrete and steel quantities.
