This project aimed to increase the port handling capacity at the port of Gioia Tauro, Italy by dredging the port channel to -17 m mean sea level (MSL) and by improving 1,895 m of the existing operational quay wall to support Super Post-Panamax vessels and a crane.
What we do
Challenge
Solution
DEME carried out deepening works in the harbour, dredging to - 17 m and -16 m by the quay wall. Representing a total sand volume of 1.2 million m3, the dredged material was then used for beach nourishment at Gioia Tauro and S. Ferdinando (2,000 m).
Used technology:
Jet grouting for consolidation of diaphragm foundation
As well as the dredging works, we levelled the sea bottom and realised the foundations of 758 prefabricated elements (6.2 x 2.4 x 6 m) made from reinforced concrete.
Then the structural improvement of the quay was required to reinstate the staticity following the deepening works, and to implement the existing structure. Approximately 2,000 m of new track beams were constructed, founded on 316 armoured concrete diaphragms at depths of – 18 m.
Finally, we constructed a treatment plant for meteoric waters and paved 80,000 m2 of quay with modified Split Mastic Asphalt, as well as installing and performing aluminothermic welding on the track type MRS125.
