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.
