Load-out and installation of the Brug van den Azijn bridge, Belgium
ALE has successfully performed the load-out and installation of the arc bridge, weighing 1,200t, using the Mega Jack 800 in Antwerp, Belgium, for De Vlaamse Waterweg.
The bridge deck and arches were transferred from the construction supports onto 40 axle lines of SPMT with 4 PPUs in a configuration of 4 x 4 file 4/6 row. ALE then loaded-out the bridge deck from the fabrication site at Gent longitudinally.
The bridge was then transported 75km with the SPMTs by barge to Antwerp on the Scheldt River. In order to pass under the low bridges on route, the arches of the bridge were positioned in pieces on top of the bridge deck with a restricted height.
Once in Antwerp, the bridge was loaded-in transversally at the site near the final location. Here, the arches were fully assembled over three months and then the entire bridge structure was jacked-up using four 500t climbing jacks and loaded-out using 28 axle lines of SPMT in a configuration of 2 x 4 file 14. It was transported by barge 2.5km under high voltage lines to the final installation site.
The bridge was then installed into its final position. To position the bridge higher than the abutments, the bridge was jacked-up 8m using ALE’s Mega Jack 800 and strand lashing was installed to protect the bridge against the wind and float-in forces.
ALE used tugboats to float-in the bridge into its position, the bridge was then lowered by 3m in between the abutments, with a clearance of 160mm. The bridge was then set-down onto the temporary bearings.
The ALE operations were completed within two weeks.
