Taio BRIDGE – Trento

CUSTOMER Taio Scarl

Supply and installation of metal structures for bridges, located in Taio (TN) as described below:
 
RIO VALLE
The bridge is formed by a single arch-frame girder, total light of 110.91 meters. To support the two shoulders, two inclined trestles have been positioned (consisting of an upper, lower and core plate (2 + 2) connected together with tubular elements made of sheet metal), which are connected to the lower platform of the bridge segments. The bridge is braced horizontally both in intrados and extrados.

The section of the upper deck is composed of three main T-beams with a full core, placed at 4.00 + 4.00 m of wheelbase, with a minimum height of 1.50 at the shoulders. The beams are joined together by bracing placed in the vertical plane (diaphragms) and in the horizontal plane (upper and lower bracing). The main beams are divided into nine segments of variable length. The main joints between the various segments of the beam are welded, with complete recovery. The remaining joints are bolted type, with high strength bolts.
 
OVERPASS WITH TWO CAMPS
Construction of two-span overpasses with an axis length of 18.00 meters, each consisting of 6 steel beams with a height of 700 mm connected transversely by solid-core diaphragms consisting of double T profiles with a height of 450 mm. The steel structures will be made of Cor-Ten type self-protected steel
The bridge was considered a first category.
 
OVERPASS WITH THREE CAMPS
Supply and installation of three-span overpasses, each consisting of 4 700 mm high steel beams connected transversely by solid core diaphragms consisting of double T profiles with a height of 450 mm. Steel structures will be made with steel self-protected type Cor – Ten.
​
The metal structures have the following dimensions:
 
RIO VALLE
  • structure length = about 110.91 mt
  • structure width = about 12.40 mt
 
TWO-CHAMBER BRIDGE
  • structure length = about 41,145 mt
  • structure width = about 9.20 mt
 
THREE CHAMBER BRIDGE
  • structure length = about 54.646 mt
  • structure width = about 6.475 mt
 
 
VIADOTTO RIO VALLE
The two masts are mounted on the shoulders of Cles and Trento on the help of crane trucks.
The ashlars are launched on the two shoulders, they are launched at the tip until they are joined together by welding (central bridge welded in place)
 
TWO-CHAMBER BRIDGE
The bridge segments were assembled in pairs of beams in the workshop, the whole span was welded in the yard in front of the bridge, the installation took place using crane trucks.
The welding of the central joint was carried out on site.
 
THREE-CHAMBER BRIDGE
The bridge segments were assembled in pairs of beams in the workshop, the whole span were welded in the yard in front of the bridge, the installation took place using crane trucks.
The welding of the central joint was carried out on site.
