Soil nail walls are retaining walls which are built from the top downwards
in cut situations where the soil has enough apparent cohesion that it can
stand up on its own during construction. The walls consist of soil nails
spaced approximately 5 ft. (1.5 m) on center with a shotcrete facing which is
often covered with a permanent cast-in-place concrete facing. Soil
nailing is not appropriate at sites consisting of clays which creep, clean
sands which will not stand up or areas below the water table. |
