DYWI® Drill Hollow Bar System
DYWI® Drill Hollow Bar soil nails provide an in-situ reinforcement for the stabilisation of DYWI® Drill Hollow Bar System Soil Nailsslopes. 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. Alternatively, a sacrificial corrosion allowance can be made by upsizing the DYWI® Drill Hollow Bar, calculating the loss of cross section over the lifespan of the soil nail to ensure the required longevity.
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.
