SITE INVESTIGATION contractor Foundation & Exploration Services has taken delivery of a new CMV3000 tracked drilling rig.
The powerful track mounted machine is suitable for drilling large diameter boreholes down to 80m with continuous flight and barrel augers, conventional open hole tricone and DTH. FES has also adapted it for cable percussion boring in saturated, unstable ground.
The firm also came up with a triple clamp arrangement of rod and casing clamps, allowing the rod string to be assembled and broken more rapidly and effectively when cased holes are being drilled.
FES says the barrel auger is particularly useful in overcoming obstacles in unconsolidated ground, such as landfills containing timber, concrete or steel. With maximum torque of 3,000kgm, five times a conventional top drive, the rig can drill vertical and inclined boreholes for piling, anchoring, water well drilling as well as for landfill gas and leachate management.
The rig is currently set up to drill 450mm diameter boreholes in excess of 70m deep for waste management contracts.
