Lien vers l'aéroport de Brisbane

The Brisbane Airport Link is a motorway connecting Brisbane’s business district to the northeast of the city, towards the airport. The construction of the line has been done in segments, with parts of the route already operational. Full completion is planned for 2024.

Dextra has been involved in the design, engineering, and supply of large FRP Soft Eyes for Tunnel Boring Machine (TBM) entry/exit points between 2009 and 2011.

Before the construction of the D-Wall, Dextra engineers designed the FRP cage, considering factors such as the size of the TBM, margin for error, soil forces, and other design parameters.

Thanks to the properties of FRP material, Tunnel Boring Machines can cut through the D-Wall in minimal time, saving schedule time and ensuring the TBM’s head remains in perfect condition.

For this project, Dextra also supplied Griptec couplers, which were used as vertical connections in the D-Walls, barrette piles, and tunnel superstructures. More than 80,000 Griptec couplers have been supplied for the tunnels of the Brisbane Airport Link.
