Can the rotary drilling rig of fine round gravel soil move?
Gravelly soil is an unconsolidated or argillaceous cemented soil with a particle size of not less than 50% of the total mass of 20mm.
Coarse gravel soil, fine gravel soil, (density capacity 650kpa) using the current engineering auger can work smoothly.
The rotary drill is very difficult to move and can only be drilled into its surface
