| Abstract |
The locks face a double challenge: a lock crossing time for a vessel of less than 30 minutes and minimizing water consumption with water-saving basins. The lock filling/emptying systems are designed to minimize the levelling time while limiting mooring forces and lock generated waves. For the lock of Catigny with a head of 14.0 m the selected system consists of lateral culverts with side ports and two water saving basins. Within a hybrid modelling approach, two physical models of the filling and emptying system of the lock of Catigny were built by Flanders Hydraulics on scale 1:25 according to Froude similarities. A simplified model of the Y-junction underneath the lock floor was used to optimize the repartition of the discharge between both lateral culverts when filling the lock from the water saving basins. Based on the tests with this simplified model a short dividing wall in the Y-junction was selected for the further design of the filling and emptying system of the lock. To study and optimize the hydraulic behaviour of the filling and emptying system a complete model of the lock was built. Three different configurations of side ports were tested: A first configuration consisting of 32 rectangular side ports, a second one consisting of 56 side ports with an optimized hydraulic geometry and the third one consisting of 32 rectangular side ports discharging into elliptical dissipation recesses in the lock bottom. The third innovative configuration combines the hydraulic advantages of a bottom filling and emptying system with the constructive advantages of a system with lateral culverts. The filling and emptying time in normal operation mode is compared to the required value of 600 s, the longitudinal, respectively transversal forces on the ECMT Vb push tow convoy in the lock chamber were compared to the criterium of 0.70 ‰, respectively 0.35 ‰. The physical model tests showed that two of the three tested port configurations fulfilled the criteria. During filling of the lock from the water saving basins, a slight uneven discharge repartition between left and right culvert existed, generating transversal forces on the ship. These transversal forces were reduced significantly due to the presence of the bottom dissipation recesses with side port configuration 3, which was selected for the further design of the lock. |
