Silverstream Landfill – Construction Techniques Ltd (March 2007)
This is a large landfill site serving two
cities, as it develops new work in some of the gullies ajoining it, the cuts require sprayed walls
and anchors to stabilise them.
Project scope
Griffiths Drilling were called in by the customer to drill the anchor holes in rows along each wall
with drainage holes also being required. The work was done around the customers progamme of
concrete spraying sections of wall.
Complicating factors and solutions
Holes of varying angles were required and the Komatsu rig showed its versatility and performance in
quickly completing the project using a down hole hammer. For the holes high up the batter our
drilling boom mounted on our 7 tonne excavator was able to provide the reach while being
comfortablely operated from the ground by wireless remote control.
