Final breakthrough in Antwerp
Linking Shipping and rail traffic.
On July 23, the S-532 Herrenknecht Mixshield reached the target shaft in the second tube. After 18 months the two tunnels for freight trains are now completed for the "Liefkenshoek Rail Link Project (LHSV)" in the area of the Antwerp seaport. Global Tunnelling Experts congratulates all involved for the successful final breakthrough and the very good tunnelling performance of the S-532 Mixshield of up to 250 meters a week.
The largest challenge when constructing both tunnels was the crossing beneath the canal dock. Overburdens are only 1.1 meters, and the passage for large ships must be kept open at all times, which means that a certain water level must be maintained. Therefore, the silty soil in the area will be replaced with mortar and then covered with a two-meter thick reinforced concrete plate. This serves as an anchor protection and as an additional weight, allowing passage of the TBMs.
From 2009 to 2011, 54 tunnel experts from Global Tunnelling Experts were provided for the Antwerp construction site. For disassembling the machine, a team of 17 experts will support the tunnel constructors of the THV Locobouw Joint Venture for the next two months. GTE supplies the ongoing jobsite work with TBM yard foremen, TBM mechanical supervisors, TBM PLC electricians, TBM loco drivers and fitters for locos, workshop, separation plant and the TBM. Furthermore tunnelling work for the cross passages proceeds and is supported by 1 foreman and 9 cross passages miners from Global Tunnelling Experts.
