VAN RUTH® ANCHOR PLUG (AP)
The VAN RUTH® ANCHOR PLUG (AP) is designed to enable grouting of overhead drill holes by anchoring a PVC hose up hole to evacuate air from blind holes in impervious formations. The ANCHOR PLUG fitted with a stainless eye pictured above left is used to facilitate up hole hoisting of equipment.
The ANCHOR PLUG is placed by pumping up through the drill string and locks in the drill hole upon leaving the rods.
GROUTING OVERHEAD BLIND DRILL HOLES the ANCHOR PLUG is inserted in to an open rod string with a length of PVC hose assembled onto the 1/2" BSP Female thread in the plug. With a stuffing box attached, the ANCHOR PLUG is pumped through the drill string up hole and from the rods near the end of the drill hole. The ANCHOR PLUG locks in place once it has left the rods. Once in place and rods have been removed and with stuffing box installed, grouting of the hole can begin. Grout is pumped up through the annulus between the PVC hose and the drill hole bleeding the displaced air through the ANCHOR PLUG and returning back down through the PVC hose. Grout discharge from the hose means grouting of the drill hole is complete.
