Gas Lift Reverse Circulation Drilling Rig

The airlift reverse circulation drill is mainly used in two fields:
Engineering construction: It performs hole-forming operations for underground projects such as cast-in-place piles and diaphragm walls;
Geological exploration: It conducts drilling and sampling work.
Its core principle is to inject compressed air to form a gas-liquid mixture, and quickly discharge cuttings through the reverse circulation method. It is especially suitable for large-diameter, deep-hole drilling and complex geological conditions such as sandy soil and pebble layers.
