I. Introduction of engineering drilling machine       

 

1.The major diameter engineering drilling rig of QJ250-1 type applies to major diameter bridge pier hole in various geologic conditions, such as ravelly ground, clay loam layer, sandy gravel, breaking layer and lithosphere as well as other various major diameter pore forming construction;


2. This drills Torque is large, the rigidity good, and the whole machine is stable and drilling efficincy high and quality of pore forming is excellent;


3. It adopts a set of drilling tool which can be used for two species of drilling technique of positive and negative circulation, it is equipped with air compressor, and can realize gas lift reverse circulation drilling;

4. The pile holder, which matches with main machinen, is equipped with five wheels tackle with two load of 600KN to move left and right on pile holder, in order to reduce the assistant time during construction;


5. This engineering drilling rig has won Scientific and Technical Advance of Construction Ministry.
