Heavy Duty Reverse Circulation Drill Rig(RCD Rig)

RCD Drilling rig(Reverse Circulation Drilling Rig) alao know as air lifting rig, is an efficient drilling method that exploits compressed air,
as it injected into the drilling pipe below warter level, to reduce the density of the internal water column and remove slurries
through the circulation. The mixture of water, air and cuttings is then flushed out through the drill pipe into settling tanks.

Our heavy duty RCD rig design for hard layer and big diameter bored piling work, can reach the drilling diameter from OD5000mm, the specification as below:
