MTR SOUTH ISLAND LINE – ADMIRALTY STATION
2014 -2016
VSL – Intrafor designed, supplied, installed, operated and monitored the underpinning system of an MTR platform to enable the excavation works to take place underneath in the expansion of Admiralty, one of Hong Kong’s busiest MTR stations, serving both the Island and the Tsuen Wan lines.
The underpinning system was designed to support the existing structure from below, through the installation of steel coffin beams and composite columns to allow the rock beneath to be removed.
To achieve this, VSL installed between four and eight hydraulic jacks at the top of each column supporting the underpinning beams to enables precise load transfer and displacement control by the use of synchronised jacking.
