Alternative to sheet piling

Copenhagen Metro

The Copenhagen Metro cut and cover tunnel involved the excavation of a 12 metre deep cutting through flinty till. Soil nails were selected as the preferred method of stabilisation, replacing sheet piling due to the difficult ground conditions, efficiency and cost effectiveness:-

• Cut and cover tunnel

• Cost effective replacement for sheet piling

• Installation rate of 350 metres per day, per rig

• Maximum deformation of only 15 mm
