San Apollinare BRIDGE - Rovigo

CUSTOMER Clea

Supply, assembly and installation of the steel bridge over the Idroveria Fissero Tartaro Canalbianco in San Apollinare in the Municipality of Rovigo (RO).
The work is carried out by means of an arc-shaped lower street on a single span of light 74 m. The supporting arches of the span, in tubular profile Ø 1000 mm, describe arcs of a circle with a radius of curvature of approximately 47.5 m and lie on planes inclined by about 12 ° with respect to the vertical towards the center road.
​
The deck, having a width of 14.8 m, is composed of 2 beams in double T profile with chain function for the arches which are hung on the arch by 6 Macalloy type hangers per side and which support the main steel girders double T with solid walls arranged with a pitch of about 5.3 m, working on the concrete slab 25 cm thick cast on 5 cm "predalles" slabs.

The scaffolding lay on two shoulders in c.a. and is fixed, for the longitudinal displacements to the shoulder only (fixed shoulder) placed on the hydraulic left of the water course and to both shoulders for the transversal movements to the axis of the deck.

The metal structures have the following dimensions:

• structure length = about 75.00 mt
• structure width = about 15.50 mt
• structure height = about 17,50 mt

 
The on-site assembly was carried out as follows:

• assembly and welding of a metal bridge structure in the area adjacent to the shoulder 1
• for the final position of the bridge, we proceed with the peak launch of the entire metal structure, from the assembly shoulder to the opposite shoulder in a definitive position. A peculiarity of this launch is the taking over of temporary parts of the front of the bridge, thus facilitating the translation of the entire metal structure.
