Further information
- geothermal drilling applications
- drilling with an auger
- drilling with a hollow stem auger
- drilling with a cable percussion device
- core drilling
- direct Rotary flush-drilling
Head preventer mode of operation (patent pending)
- light, compact and robust construction
- casing and inner rods are drilled out together
- casing and inner rods are telescopeable
How does it work?
- The head preventer is clamped by the chuck head
- Drill rods and casings are screwed onto the head preventer and are drilled out as usual
- The drilling mud is transported downwards by the inner rods and is transported upwards inside the jacket space
- The head preventer discharges the drill cuttings into a container through a hose
- The drilling mud out of the container is carried back into circulation again
- After the overburden, the head preventer is taken out of the chuck head
- Afterwards, flush drilling is continued with the ground preventer
