The Trilogiport Bridge is located at Visé, Belgium and was installed in five sections, each weighing between 221-737t and built at three different site locations in the region.
The first installation took place on 24 January, with the bridge section jacked up to 6.5m and transported by 24 axle lines of SPMTs to its final position on land, before being lowered with climbing jacks. The second section followed a similar process, with the section jacked up to 9m using ALE’s jacking system and installed on 20 axle lines of SPMTs.
The third section was installed over the water, and was loaded-out using 24 axle lines of SPMTs on two barges, coupled together as a catamaran, before being jacked up to a height of 10.5m. For the final two sections, the two barges floated under the existing bridge — the Pont de Hermalle sous-Argenteau — before the fourth section was installed using ALE’s jacking system and the final piece was lifted using four 70t strandjacks previously installed on the third and fourth bridge sections.
The project was completed within three months, said ALE’s project manager Hans de Hoon.
