A shallow foundation was therefore ruled out. Based on existing experience with comparable ground conditions, only grouted piles were considered.
22,750 m of TRM 170/9.0 piles were installed with TRM DN 320 grouted pile shoes to support the two main abutments and several bridge piers. A further 13,510 m were installed for the foundations of subways and retaining walls. The piles were designed as grouted compression and alter-nating load (compression/tension) piles. A total of 36,260 m of TRM 170/9.0 piles were installed for the project.
Fast. Simple. Safe.
