Trevi Construction has announced completion of 175 jet grouted columns for the temporary works on Hong Kong’s West Kowloon Terminus (WKT) for the Express Rail Link (XRL) project.
The columns have been installed for main contracting joint venture Leighton Gammon to provide excavation and lateral support for the new station which extends through reclaimed ground and up to 29m below ground level.
Trevi has installed the jet grouted columns to stabilise the marine deposits and the columns, which were designed by Atkins, start 2m above the marine deposits and extend 2m below. The thickness of the marine deposits was variable and the length of each 2m diameter column had to be determined during the drilling of the column.
The WKT will be the terminus for XRL and will connect Hong Kong to mainland China by rail for the first time.
