Development of GYD-20 Drill with Full-hydraulic Dynamic Head
Abstract:Aiming at the disadvantages of long manufacturing cycle, low degree of automation, high labor intensity and low construction efficiency of traditional drill, GYD-20 drill with full-hydraulic dynamic head is developed. The paper introduces this drill about its structure characteristics and the application effects in large diameter foundation pile hole and mine ventilation hole drilling.
