BTS December Meeting: Tideway TBM Delivery

At Greenwich Pumping Station, a large acoustic enclosure is being constructed over a diaphragm wall drop shaft in preparation for TBM delivery and lowering to construct the mega Tideway Tunnel. However existing underground tunnels must be protected from the delivery loading of the TBM. In particular a maze of deep existing brick sewers and underground sewerage chambers had to be protected from TBM transiting directly overhead. This presentation will give a detailed review of the inception, design, construction and full scale load testing of a pile assist RC raft protection system, which also doubles up as the foundation of the acoustic enclosure and gantry cranes for TBM delivery.
