Winchburgh Cutting soil nails

Bell Access & Engineering Ltd were contracted by AMCO-Giffen to install 16 soil nails in a retaining wall at Winchburgh near Edinburgh.

To successfully carry out the works, Bell Access utilised our Ripamonti soil nailing drill rig, mounted via an Engcon head to a road rail excavator.

The Bell Access IRATA qualified rope access team installed 16 self-drilling anchor bars to a depth of 8m over a period of 3 scheduled Saturday night shifts.

The team diamond core drilled 86mm holes thorough the existing stone retaining wall to allow access for the soil nail without damaging the structure.

Following installation these anchors were pull-tested using a Hydrajaws 2008 model pull-tester through load cycles up to 50kN.
