The last of 120 record-breaking 22m diameter steel piles has been driven on the Hong Kong-Zhuhai-Macau Bridge in front of an audience of 200 people.
The 39.6m long piles have been used to construct two circular sea bound walls in the South China Sea for the new bridge and will form the bulkheads for two artificial islands. The islands will form the transition structures between the 6.7km tunnelled section – built to allow deep water ship access to the Pearl River Delta from the South China Sea – and the bridge section of the link.
Main contractor Chinese contractor First Harbor Marine Group China used American Piledriving Equipment’s giant eight-hammer piledriver - the Octakong – to drive the steel piles for the seawall. Installation of the piles took seven months to complete.
The new link is due to be completed in 2016
