Wall Protection: DTH Hammers Reduce Collapse for Water Well Drilling Rigs
The water well drilling rig DTH hammer minimizes radial disturbance to well walls.
- Focused impact: Energy focus at bit tip. Works great in loose, collapse-prone sand layers.
- Pipe-following drilling: Drives casing forward with the hammer. A river project achieved 100% wall integrity in 15m quicksand.
- Low disturbance in clay: Avoids soil structure damage. Swelling soil saw only 2mm later settlement.
Traditional rotary rigs had 30% collapse here. The water well drilling rig ensures safer, more stable wells.
