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.

Definition:
reinforcement of the cut ground progressively of its excavation by the installation of passive bars. To prevent that the ground does not run out between the bars a facing generally made up one places of a treuillis and a shotcrete
Characteristics:
excavation in phases (1 with 1.5m excavation, installation of the nails, shotcrete, excavation 1 with 1.5m, installation of the nails, etc)
displacement minimal at the head of the wall is equal to 2promille height of the maximum excavation. Displacement is inevitable to introduce friction into the passive nails.
without vibrations
method calculated like wall of weight (standard "Clouterre")
Scope of application:
reinforcement of the existing taluds
realization of the higher and/or stiffer slopes
limited to the sites except ground water
unusable in grounds non-cohesive short-term
