1. Application

HF-20 drilling rig is one kind of full hydraulic power head (top drive) drilling rig. It can be applied in direction jet-grouting, pendulum jet-grouting, circulation jet-grouting work, and used for high pressure jet-grouting work in Quaternary Cover Area such as soil, sand, pebbly sand and so on. It also can be applied for anti-handling of infiltration and seepage of industrial, urban and civil building construction, high building basement, and hydraulic engineering, such as roadbed, bridges, dam foundation and subway, etc.;

 

The drilling rig has a variety of drilling methods, like: Dry-auger, DTH hammer impacting, ODEX tools casing following, etc. Therefore, it can be adaptable in different terrain and complex drill work condition in order to effectively resolve the problem of difficulty of drilling in loose cover strata, gravel layers, broken rock strata. It should have a very widely usage.

 

The drilling rig can apply singe pipe, duplex pipe, triplex pipe tools and so on. Optional pendulum jetting device can be added to achieve the pendulum jet-grouting function.

 

The drilling rig has various chassis mode like skid mounted, crawler mounted, step walk mounted and so on. Depending on customer’s requirement, customer can decide to choose which chassis by himself.
