Anchor plugs (ap) are designed to allow grouting of holes above horizontal to evacuate air from blind holes in tight formations. The anchor plug is inserted in open rod line with pvc hose and stuffing box attached. The anchor plug is then pumped to near end of hole, out of rod line. PVC hose is cut 1.5 to 2 meters from stuffing box, rods removed from hole, stuffing box reinstalled in stem pipe or Grout and Water Control Packer (GWC), grout is then pumped uphole, bleeding displaced air through pvc hose until grout discharges from pvc hose. Anchor plugs can also be supplied with adaptors to suit up hole hoisting purposes. Construction: Aluminium |
