| Abstract: |
The municipality of Amsterdam is currently constructing the new metro line, the North/South-line. This metro line passes through Amsterdam’s Central Station. The contractor must therefore construct an immersed tunnel under the station platforms, the 15 tracks and the historical station building. It must be avoided that the historical building that consists of brickwork from 1890 is damaged. Rail traffic and rail passengers cannot be inconvenienced during construction and safety must be guaranteed. The realization of the retaining wall under Amsterdam Central Station is achieved by a newly developed innovative method for installing watertight interlocked tubular steel piles to a depth of - 66 metres NAP. |
