Saida- Moulay, Algeria
Saida-Moulay Railway Line
Project for the launching of the VI 1, VI 6, VI 12 viaducts on the HS Saida- Moulay railway line.
Launching and prefabrication equipment for three rail viaducts made of prestressed reinforced concrete for extrusion on the prefabrication field with a box-section. The most significant work is the VI 12 viaduct, built with a continuous beam scheme with 8 spans and spans equal to approximately 36 m, 6 x 45 m, 36 m respectively, for a total of approximately 342 m. The route of the viaduct develops in a curve with a constant radius of curvature, equal to 3’200 m along the layout axis. The VI 6 viaduct, on the other hand, is spread over 4 spans of 36 m, 2 x 45 m, 36 m for a total of 162 m. The launching equipment consists of the launching nose with a length of approximately 38 (made with two I-section beams of variable height and equipped with diaphragms and lower bracing),
from the rear beak for the final push phases, from the temporary supports with lateral restraints and from the push group in correspondence with the throwing abutment. The prefabrication field extends for about 50 m and is made up of the support structures for the bottom and side formworks, the lateral sides and all the moving elements of the sides and bottoms.
