Discussion of Continuous Auger Drilling Technology with Multi-function Auger Drill
Abstract:Based on the calculation of resistance moment in continuous auger drilling, resistance moment values of different borehole diameter and depth were obtained. The comparison was made on the drilling tool intensity, and continuous auger drilling tool parameters of different borehole diameter were presented. The paper also introduced the different continuous auger drilling bit with different structures and accessory tools, briefly discussed the construction technology of continuous auger drilling with multi-function drill.
