Drive Drilling Systems
D 88.9 - D 152.4 With Hydraulic Drifter
The name “Overburden Drilling” results from the composition of the earth’s crust. The bedrock is under loose layers of earth consisting of sand, gravel and boulders. As well as lose ground and other deposits. All these formations fall under the umbrella term “Overburden”, which overlies the bedrock.
Certain drilling processes make it necessary to support the wall with tubes. The drive drilling systems shown here is powered by a hydraulic hammer, which turns and strikes the whole drill string from above, consisting of an outer and inner rod. Flush air or water down the center of the inner drill string to the end of the drill hole. It discharges the cuttings in the gap between both rods through the flushing holes above. This drilling system is for relatively shallow depths.
