Bearing Plate Assembly
Bearing plates are available in any size with or without welded concrete anchors (studs).
ASTM A36 and ASTM A572 grade 50 steel material are used for the bearing plates, stud materials conform generally to ASTM A108.
One or two beveled washers are typically used to adjust to the soil nail angle.
Centralizers made from PVC or HDPE are available for all hole diameters and nail configurations. They are used mostly with THREADBAR® soil nail.
Wall Forming with DYWIDAG Soil Nails
When your project requires a cast-in-place wall in front of the complete soil nailed wall, DSI offers a variety of methods to use the existing soil nails as a means of vertical form support. Reusable she-bolts are available for some of the more common THREADBAR® sizes (see the detail to the left).
For any DYWIDAG Soil Nail, a coupler with an extension bar provides a simple and effective means of transferring form loads to the nails. A sleeve over the bar allows for multiple reuse of the extension bar and anchorage.
