On March 17th, the north embankment bridge of the Anlu Expressway Yellow River Super Major Bridge was successfully joined, with all steel structure construction completed.
As part of the Anlu Expressway Yellow River Super Major Bridge, the north embankment bridge crosses the Yellow River embankment within Yuanyang County, adopting a variable cross-section double-box composite steel-concrete beam structure. It is 275 meters long, 41.5 meters wide, with a total weight of 5,300 tons, consisting of 23 segments and a maximum lifting weight of 58 tons.
The construction site has a complex terrain, with the box girder spanning across 3 village roads and diagonally crossing the Yellow River embankment. The embankment slopes on both sides have a 3-tier stair shape with a height difference of 15.86 meters, greatly affecting the crane positioning and girder lifting sequence. The project department scientifically planned according to the site topography, precisely mapped out the crawler crane positions and steel girder lifting sequence to ensure safe and controlled steel girder lifting operations.
In the next step, the construction unit will further coordinate resource allocation, accelerate the bridge deck paving and prestressing operations, to ensure the completion of subsequent milestones.
