  • Bridge crossing Messina Strait

    Control of the detailed design of the bridge foundations (tower and anchor blocks) and of the roads and railway links (foundations of civil structures; tunnels and tunnels portals). The bridge main span is 3300m long; it is supported by two towers of 360m height. The tower foundations include diaphragms walls (they are also the retaining structures for the foundations soils excavation) with deep jet-grouting columns inside.Around the foundation blocks, a wide and deep section of the natural soil is treated with jet grouting columns designed in order to prevent liquefaction during seismic events and to provide a strong confinement against horizontal loads.Anchor blocks are deeply embedded below grade and surrounded by diaphragm walls retaining structures.The road and railway links include many civil structures such as viaducts and 50kms of large diameter tunnels.

Costa Concordia Parbuckling

For the purposes of the safe removal of the Costa Concordia wreck, SOIL Srl has been involved into all aspects concerning the geological and geotechnical design and assistance for the construction of the foundation structures.

The Costa Concordia Wreck Removal Project foresaw in the first stage the rotation of the wreck to its vertical position (parbuckling phase) and subsequently its re-floating by means of the installation of steel caissons on both sides of the ship.

The parbuckling required the construction of underwater anchoring structures on the landward side of wreck and the installation of three submerged platforms for its temporary support in vertical position on the seaward side. The structures were built respectively at water depths of 5 ÷ 10m and 40 ÷ 50m below sea level. Drilled steel piles (D = 2m) were designed for the platforms foundations.

The activities performed by SOIL Srl concerned:
