In shielded mechanized tunnelling, the annular void created during the advancement of a Tunnel Boring Machine (TBM) must be continuously filled to minimize surface settlements and ensure optimal contact between the segment lining and the surrounding soil. Two component grout is widely used in the backfilling process due to its ability to meet both operational and performance requirements. This grout system...
Bentonite slurries are essential for the operation of Slurry Tunnel Boring Machines (TBMs), helping to stabilize the excavation face, prevent soil collapse, and control groundwater inflow. This study examines the performance of a sodium-activated bentonite slurry used in tunnelling, focusing on its physical-chemical properties, rheological behavior, and interaction with soil. Tests were conducted to measure...
