In water well drilling rig operations, spiral drill
rods paired with scraper bits matter most. Spiral blades carry clay and loam cuttings out, stopping secondary bonding at the hole bottom.
Their hollow structure delivers flushing fluid, boosting debris removal. Here’s how to match them:
-
For sticky clay, use large-pitch spiral rods. They speed up cuttings’ upward movement efficiently.
-
For sandy loam, thicken spiral blades. This enhances wear resistance against sand particles.
-
Seal rod connections tightly. Prevent mud leaks to keep debris removal efficient and steady.
With this setup, water well drilling rigs handle soft soils smoothly and continuously.
