THE L CRAEYBECKX TUNNEL AT ANVERS

DE L CRAEYBECKXTUNNEL TE ANTWERPEN

This article described the design and construction of the L craeybeckx tunnel, situated on the new road between Brussels and anvers. Because of the risk of subsidance to nearby buildings and the disruption of the water table the initial open trench construction was abandoned. The final solution involved the construction, about 20 m underground, of 1 M thick reinforced concrete partitions situated at least 2 M below the boom clay surface layer. The tunnel was made up of a reinforced concrete slab between 1.45 m and 1.8 M thick, restrained at the top of the two exterior wall partitions, and which, held up by neoprene supports, passed above the two service corridor partitions situated at the centre of the tunnel. To increase fire protection, the road pavement inside the tunnel was of continuous reinforced concrete. Two different coatings were used on the lateral partitions in order to meet specifications concerning wall stability and fire protection versus ventilation requirements. A description of the electrical and mechanical equipment was also provided. Brief details were given of the lighting, ventilation, signalling, driver information, radio communication and water pumping equipment.
