Deep Diaphragm Wall Activities at RandstadRail Project in Rotterdam, The Netherlands
Klaus Pöllath; Frank Haehnig; Johannes Glückert

The Netherlands RandstadRail project makes use of a large range of sophisticated geotechnical techniques to allow a shield driven tunnel to approach the central station of Rotterdam. This paper describes the construction of three deep excavation pits constructed with 1.2 m and 1.5 m thick diaphragm walls. Besides the presentation of the actual diaphragm wall activities special consideration is given to the break-in and break-out situations of the Tunnel Boring Machine (TBM) into the deep excavations pits using sealing blocks and partly glass fibre reinforcement in the diaphragm walls.
