The water well drilling rig often uses small-diameter
DTH hammers (65-110mm) as standard.
-
Highly portable: Fits 3-6m³/min compressors, weighs <1.5 tons. Transportable by tricycle to remote areas.
-
Ideal for rural shallow wells: A 50m orchard well took 3 days, costing 8,000 yuan. Damaged <5㎡ farmland.
-
Has clear limits: Drills 1-2m/day in granite, yields <30m³/h. Poor stability in wells >100m.
Its moderate impact frequency (1000-1400/min) aids pipe installation. The water well drilling rig suits small-scale rural use.
