Spring Farm Parkway
Project description
Mining is Australia is not limited to the most remote parts of the country, but takes place even close to major cities where highways must be constructed.
Since the Spring Farm Parkway near Sydney passes through a mining area the highway must be built to accommodate any ground subsidence that may result from the mining activities.
The four-lane highway of Stage 1 crosses an area that is subjected to longwall mining, so its main bridge structure had to be designed to accommodate large movements and rotations.
mageba scope
Having supported the bridge designers from the project’s early stages,
mageba went on to design, manufacture and test the required components, which included 48 RESTON-SPHERICAL bearings, 44 m of TENSA-MODULAR LR9 joint, 22 m of TENSA-MODULAR LR9-LS, featuring mageba’s special noise-reducing surfacing, 27 m of TENSA-GRIP RS expansion joint and 56 m of elastomeric bearing strips based on the LASTO-BLOCK F bearing in 2-metre lengths.
Were it not for the mining activity in the area, the bridge’s movements and rotations could have been facilitated by smaller, simpler bearings and expansion joints, but thanks to the expert support provided by mageba’s team in Sydney, the optimal solution could be developed to meet this structure’s special subsidence-related challenges.
TENSA-GRIP joints were supplied to accommodate smaller longitudinal movements
