Grand Steel Piling
/ Copergas, GDK, Brazil

Copergas, GDK, Brazil

The main dock, constructed of sheet piling, has a maximum depth of 9,80 metres and offers a total quay length of 1 050 metres. Installing the 4 500 tonnes of sheet piling in soil with very difficult geotechnical characteristics required a specific piling procedure to be designed in advance of the main scheme.The size chosen is L605 larssen interlock sheet piles. The sheet piles shall be installed by means of a variable frequency vibrator with an adjustable eccentric moment capable of generating a minimum centrifugal force of 3 000kN. The jetting system to consist of 4 jets of 3/4" diameter welded to each pair of sheet piles.
