In a soil nail application, the SOIL SCREW® Retention Wall System constructs a gravity wall to reinforce in-situ soil with screw anchors nearly horizontal. Anchor sizes and grid spacing are determined by soil conditions and load requirements. A reinforced shotcrete veneer often is applied to the face.
  • Same installing equipment as soil nails
  • Terminations: Threadbar, stud, crosspin
  • Capacity proportional to install torque
  • No excavation or spoils to remove
  • Installs in any weather conditions
  • Immediate loading
  • No drilling
  • Installs in limited access areas

To remove the performance uncertainties and associated costs of grouted soil nails in soils of low shear strength, a SOIL SCREW® anchor acts as a bearing device. This load-bearing mode is its fundamental superiority compared to a grouted anchor which relies on friction between the soil and the grout.

SOIL SCREW® Design Manual, available on www.abchance.com, is based on FHWA design-build guidelines and key software for internal and global stability. It also compares to tiebacks and MSE walls.

For job-specifi c selections, leading and extension sections come with two or three 8"-diameter helical bearing plates spaced along the entire length of their 11⁄2" square shafts. All components are available hot-dip galvanized per ASTM A 153 after fabrication. Each SOIL SCREW anchor has a 5,500 ft-lb torque rating and a 70 kip ultimate tension rating.
