Duktus pile driving breaks ground in South Africa

Construction of a new solar radiation energy plant in South Africa is being fast tracked with installation of up to 400 steel piles per day by contractor Geopile Africa.

The project calls for the 50,000 piles for the new energy plant in Northern Cape to be installed in six months.

According to Geopile operations manager Jared Prowse, the Duktus system using Atlas Copco HB 2000 hydraulic breakers mounted on Volvo excavators is ideal for the project.

“These solar field sites are generally very large, in some cases 3 km long x 1.25 km wide so we need a flexible piling solution,” said Prowse. The Duktus system being used by Geopile concentrates 4,000J into the pile driving shoe to allow the piles to be driven easily and quickly through the abrasive, harder layers in the upper soils.

“So far our average pile production rate is five minutes per pile and with four piling rigs on site we can install up to 400 Duktus piles per day,” said Prowse.
