Rotary drilling rig is in place → buried protective tube → drill is rotated lightly and drilled! When the drill bit is filled with earth and sand, lift it out of the hole → rotate the rotary drilling rig to the ground and pour the earth and sand in the earthwork or on the ground → close the drill bit valve, rotate the rotary drilling rig back to its original position, lock the rotary rig → put down Drill bit → drilling completed, clear the hole and determine the depth → into the reinforcement cages and catheters → concrete infusion → pull out the protective tube and clear the pile head sinking backfill, piles.
Rotary manufacturers also sell three wheeled rotary drilling rigs. Piling equipment has received critical acclaim.
