  Robot Cutters Clean Concrete
At 120 m

 

Turkish-Italian construction company ICA Construction is constructing an 11.57 km section of the highway under a US$1.6 billion contract and four-year construction programme that includes three major high-level bridges, together with low-level viaducts and smaller overbridges.

One of the bridges is the Petrovsky Fairway Bridge, a 560 m cable-stayed structure across the River Neva to link two islands.

     The bridge, with a length of the central span is 240 m, and the bridge under-clearance is 25 m, will be a visually impressive structure, with two needle-shaped towers each 120 m high.

The deck will be supported by four planes of cables: the cables supporting the deck units closest to the tower will be connected to the top of the tower, with those towards the mid span connected at a lower level.

ICA Construction of St Petersburg has used two Aquajet robotic hydrodemolition machines to clear concrete from around the inner steel structure at the the top of the120 m high bridge pylon.
