Dublin Port tunnel - Ireland, 70, 000 metres of nails 15, 000 m2 of shotcrete

 

The nailed retaining wall is the archetype of light,
flexible shoring combined with the terrain.

This shoring relies essentially on the stabilising
capacity of the nails combined with a containment
skin in shotcrete.

Excavation is performed in successive top down
stages with immediate implementation of the
nails and shotcrete.
