Cellcore in action at Tyne Tunnel

摘要

Engineers on the New Tyne Tunnel Crossing have specified Cellcore from Cordek to address the issues of ground uplift caused by deep excavation on the access road leading to the tunnel. Expanded polystyrene manufactured by Jablite is supplied to Cordek to produce the patented Cellcore system. Cellcore from Cordek is a honeycomb of interlocking expanded polystyrene sections, which are designed to collapse at a pre-determined load. Cellcore allows the EPS to compress and deform to accommodate uplift, thereby reducing the forces that would otherwise be transmitted to the concrete slab foundations. This provided civil and structural engineers Aecom and High Point Rendell with a solution for dealing with the overburden recovery associated with the deep excavations on the North and South side of the tunnel.
