Technical specifications
Driven tube piles
150 no.
Ø 273 mm - 324 mm - 355 mm
up to 12 m long
Circular economy on site
Old pipes were reused as lost casings and the remaining pieces of tubes were turned into plugs for the tube piles.
Reinforcing local skills
Franki Foundations favored local workers to work on this project. We sent a team leader and one workman from the headquarters to train five local workmen.
Minimizing environmental impact
Thanks to the choice for driven cast-in-place piles, the amount of raw materials used, waste and transport could be reduced:
Reducing the piles’ length and diameter by about 30% meant that the quantity of cement to be poured into the ground could be reduced by 50%, which of course had an impact on the number of transports needed.
Thinking about the a safe and optimized transport, the machine has been adapted in order to fit in one standard container. Tubes were also nested in each other to use the container's volume at his best.
Plus, the choice of a complete discharge technique meant less displaced earth, and thus less waste and transport.
