Working Principle
Drilling and rock breaking: Power drives the drilling tool to rotate/impact, with the drill bit cutting through formation rock to create boreholes.
Slag discharge cycle: Mud or compressed air carries rock debris to the surface through the borehole-drill pipe gap for continuous slag removal.
Depth control: Winch and hydraulic feeding system precisely control drilling tool speed and pressure to maintain borehole verticality.
Well completion: After reaching target depth, well pipe insertion and filter material filling complete the water well construction.
