In this video we assemble a DIY micro drill rig (tiny DC motor + drill bit + frame) and a submersible water pump, then test drilling a small “well” and pumping water through tubing. I explain the mechanism, torque limits, and 3 upgrades for better performance.
[pdf] PVC or steel casings are commonly used for sandy soil due to their strength and resistance to corrosion. Selecting the right drilling equipment is critical for success. For sandy soil, you may opt for a portable drilling rig that can efficiently penetrate the sand layer.
[pdf] Crawler type deep (water) well drilling rigs adopts full hydraulic control, top drive drives the rotation of drilling tools, and the drilling efficiency is extremely high. The overall layout is reasonable, and it adopts all-ground chassis for transportation, with good maneuverability.
