The word ‘wall’ may in fact be misleading. The quay is built on five rows of piles over the 800 metre length on which a 35 metre wide concrete platform is built, consisting of large concrete prefabricated elements placed as tiles onto the…Read more
For this project, Jan De Nul built its own concrete batching plant on the spot. We had to do this to be able to meet the strict quality requirements of the contract that could be impacted when using local ready-mix concrete suppliers, due to traffic and other delays says Operational Engineer Civil Works and Italian Nicola Pulvirenti. “Taking everything into consideration regarding concrete for this project we decided it is better to make it ourselves. We observe the quality procedure very strictly and after every pouring of concrete, we perform additional strength and permeability tests. So far, this is going very well.”
The concrete batching plant is located at less than a kilometre from the construction site. “We built it completely from scratch, including electricity and water supplying facilities, a silo for cement and everything we need to make concrete. We have six concrete mixing trucks for distributing the concrete over the site and two concrete pumps. When this project is ready, we can dismantle the whole plant and use it for another project elsewhere.” The concrete is used for the piles and covering slab, in all about 55,000 m³ of concrete.
Next to the concrete mixing plant, Jan De Nul also has its own prefabrication workshop on site where all concrete prefabricated elements are made. At the same location, all of the concrete reinforcement is cut, bent and spun to make prefabricated cages for installation in the piles, the quay deck, ...
