AI Technical Summary
Existing drilling machines are unable to form rectangular anti-slide pile holes with horizontal cantilever in rock strata, and the low integration of drilling and slag removal equipment leads to low construction efficiency and high cost.
The drilling rig is suspended by cable and drills under its own weight. It combines horizontal and vertical drilling components for step-by-step drilling and is equipped with mixing, crushing, slag suction and grouting systems to achieve step-by-step drilling and simultaneous slag removal of rectangular pile holes.
It enables efficient drilling of rectangular pile holes for horizontal cantilever structures within rock strata, reducing construction steps, lowering costs, and improving construction efficiency and equipment integration.
