Development and application of CBJ·-10 percussion sampling drill rig

Abstract:

Comparing with conventional trenching exploration and rotary drilling, geological soil sampling by percussion drilling has the advantage of high core recovery, high sampling quality and less damage to the environment. A portable percussion drill rig was designed with continuous improvements made through the analysis of the impact principle, the design of the drilling tool and the analysis and calculation of the structure of the pipe puller multiple design verifications, and twice field trials. Practice has proved that the percussion sampling drill rig can work with high efficiency with hi-fi soil samples, which can meet the technical requirements of high-quality soil sampling works.
