Advantage of Crawler Type 180m Borehole Drilling Machine For Soil Testing
- With hydraulic automatic feeding device, elevated drilling efficiency.
- Large torque and drilling diameter.
- With a spherical jaw holding mechanism and the rod replacement with out breakdown, high efficiency.
- Compact structure, small volume, light weight, high detacability, easy transportation and suitable for operations in plains or mountain areas.
Operation method of Borehole Drilling Machine
1. After the drill bit of the hydraulic well drilling rig is drilled into the structure, the center drilling tool needs to be replaced in time. First, the bottom of the hole needs to be cleaned, and then the residue at the bottom of the hole needs to be blown clean. After the bit stops rotating, drill out the bit in the hydraulic well drill. It is most suitable when the lifting force is slow enough to lift the bit.
2. Drilling process summarizes the bit of hydraulic well drilling rig. It is also necessary to pay close attention to the follow-up conditions of casing, understand the specific situation of drilling in time, clean up the drilling in time, and drill the bit on the well drilling rig. Strong lifting is prohibited in this process.
