Owner Deurganckdocksluis nv General Contractor THV Waaslandsluis Engineering Office ARCADIS Belgium nv Construction Period 2011 - 2016 The second lock of the Waaslandhaven includes a bascule bridge at each end. These bridges combine road, railway, pedestrian and cyclist crossings, ensuring that traffic can constantly flow over the lock and that companies on the left bank are easily accessible. The bascule bridge is a steel truss bridge with a width of 20.5 m, a length of 97.6 m and a weight of about 3,600 tons, while the lock itself measures 500 m long and 68 m wide. The bridge has two lanes for car traffic, a railway and a separate bike lane. The deck includes an orthotropic plate which is finished with a thin layer of epoxy. The bicycle and footpaths are in cantilever and are attached to the bottom edge of the bridge structure. The rear of the bridge is provided with a caisson which acts as a counterweight. The bridge is also balanced so that the structure is in equilibrium at the level of the rotation axis. The axis is connected to the walls of the basement of the bridge via a casting provided by roller bearings. A substantial part of the structural calculations consists of a fatigue analysis. The stress ranges were calculated using a 3D beam model of the bridge, as well as by using detailed models of the connections between the orthotropic deck and the casting. ARCADIS Belgium nv
