Eastern Mangroves Project in Abu Dhabi, UAE

2600 tons of GPU 14  The top soil consist of 4 m thick clayey silt with poor bearing capacity overlying two sand layers interrupted by clayey peat at -15 to -20 m. Sand was placed over the inclined top soil to create a horizontal planum.GPU14 sheet piles were installed as temporary soil retaining wall enabling land-based installation of the heavy steel piles forming the harbour walls. A vibratory hammer based on a jack-up barge was used to drive the 18 m long  piles a couple of metres off the location of the permanent wall. Sand was also placed behind the temporary sheet piles installed in front of the planned waiting and mooring areas. Sand was piled up with ships and lorries to EL. +2.5 m. A stone-secured embankment permitted the reduction of soil pressure on the temporary cantilever GPU14 sheet pile wall. A vertical drainage system was installed to increase the bearing capacity of the soil, thus reducing the risks of later settlements.
