In the Rotterdam area, a new motorway tunnel is under construction. Due to the challenging geological situation, the job has been done in various stages, using different equipment.
The slurry pump unit pumped the sand from the building pit through a booster to a storage area some 700 m along.
The next layer was a tricky one; the complete building pit surface had a 5 m thick layer of clay. This clay later was removed using grabs.
The dredge pump suction head was supplied with plenty of jet water at 8 bar pressure.
