The water well drilling rig DTH hammer handles complex formations with ease.
-
Flexible pressure adjustment:
Lower to 0.6-0.8MPa in clay;
raise to 1.2-1.5MPa in hard rock.
Avoids over-disturbing soft layers.
-
Controls well deviation: Adjusts parameters in alternating layers. A hill project kept diameter deviation under 5mm, no slanting.
-
Suits fractured zones: High-frequency impacts follow cracks, reducing jamming. One project hit 95% success here.
Dry drilling avoids aquifer pollution,
ideal for drinking water wells.
The water well drilling rig works reliably in all cases.
