- Abstract
Reaming pile is an energy-saving emission reduction cast-in-place pile and the rotary reaming device of rotary drilling rig is a kind of reaming facility for the reaming pile, on which the aperture is controlled by the telescopic cylinder. The problems existing on the former device on which the flow of hydraulic oil was used to control the aperture were studied and the design solution was improved. For the accurate aperture, the author carried out intelligent PID control on the expansion and contraction quantity of the telescopic cylinder, established a mathematic model, run simulation with MATLAB to verify the solution feasibility, guarantee the aperture effectively and then further verified it during the actual site construction.
