Scene

High-lift multifunctional drilling rig developed according to the domestic subway, tunnel, highslope, high-rise buildings, airports, ground-source heat pumps and other deep foundation pitsfor pipe scaffolding, anchoring, jet grouting and waterfalling.

Characteristic

Three-wing drill bit drilling, mud discharge. Suitable for soil layers, sand layers and other geological formations.
Air drilling with air-drillinghammer and air discharge. Suitable for rock layer, broken layer construction.
Bottom-of-hole, fluid-activated hammer drilling, mud slurry discharge. Suitable for the construction of broken layers, sand and pebble layers and other strata with large water content.
Casing drilling
Single, double and triple jet grouting, fixed jet grouting, pendulum jet grouting and other jet grouting and expanding head anchor processes.
Drill pipe and casing composite drilling
