DYWI ® Drill Hollow Bar System

 

Soil Nails

DYWI ® Drill Hollow Bar soil nails provide an in-situ reinforcement for the stabilisation of slopes. Typical applications include railway embankments and road widening projects. The DYWI ® Drill Hollow Bar System offers high rates of production when installed using the simultaneous drill and grout method.

For permanent soil nailing applications, galvanizing or epoxy coating, the soil nail provides a practical means of extending the life of the nail.

Face details consist of a bearing plate with beveled washers when required for angle compensation. For confinement of the face between the bearing plates, a shotcrete or reinforced geogrid will provide the necessary restraint.
