AI Technical Summary
Existing drilling rigs are unable to form rectangular anti-slide pile holes with haunches and horizontal cantilever in rock and soil, and the low integration of drilling and slag removal equipment leads to low construction efficiency and high cost.
An asynchronous drilling method is adopted, with a mud handling mechanism, a haunch drill assembly, a horizontal drill assembly, and a vertical drill assembly set sequentially from top to bottom on the drilling rig. By asynchronously coordinating the movement of each assembly, the drilling of rectangular pile holes with a haunch horizontal cantilever is realized, and vacuum suction and mud injection technology are combined for synchronous slag removal.
It enables efficient drilling in soil and rock formations, reduces construction steps, lowers costs, improves construction efficiency, and prevents clogging of the slag discharge pipe.
