This lecture will discuss an integrated method for safely constructing cross passages in challenging geological conditions between two tunnel boring machine (TBM)-driven running tunnels on the HS2 Project. Of the 20 cross passages to be constructed, 14 are utilising artificial ground freezing (AGF) and 3 are employing dewatering and depressurisation methods.
Traditionally, AGF has been utilised primarily for rescue operations. However, its application within the UK has been limited due to cost and time constraints. The implementation of AGF on this project is the most extensive AGF application undertaken on a single project within the UK. Lessons learned from this approach will also be discussed, providing insights for future projects.
After the event, there will be a networking session at the ICE Kendal's bar, with food sponsored by CK-Tech Ltd and drinks sponsored by Normet.
