Muge Bridge - Santarém

Assignment EN 118 main carriageway - km no. 6.600 - BRIDGE OVER MUGE BROOK
Localization Salvaterra de Magos, District of Santarém
Main characteristics Construction of a bridge using a combination of steel profiles and reinforced concrete. The bridge has two spans, providing a total span length of 60 metres.

This bridge will replace the existing one – a metal bridge with four spans, constructed in the 1940s.
The single most striking feature of this work contract is the construction of the new bridge beside the existing bridge, which after conclusion was then shifted into its definitive position in 3 days, during which time road traffic was cut off.

Main tasks:
• Reinforced concrete piles, 1000 mm in diameter, with a lost steel tube, each one around 30.0 metres deep.
• Construction of a temporary metal structure on which to construct the deck. This structure consists of three metal portals with track girders, six roller devices and braking mechanisms.
• Construction of the deck – the main structure of which is composed of two "I” beams of variable inertia, with a maximum height of 1.30 m and length of 60.0 m. The deck is a solid reinforced concrete slab.
• Shifting the deck into place over a period of 3 days, implying closing the bridge to traffic.

The process is composed of the following steps:
- Demolition of the existing metal bridge using an 80-ton crane and hydraulic scissors mounted on a rotating platform.
- Sliding the deck over the rollers into place. The force is provided by three 110-ton hydraulic bar jacks.
- Monitoring the sliding process using cameras mounted on each track beam, to control the movement.
- Raising the bridge, removing the rollers and inserting the definitive supports, using eight 159-ton hydraulic jacks
