Research on Sampling Technology for Environmental Scientific Drilling in Liuchangying

Abstract:

According to the requirement of high coring rate in environmental sampling， SDR-100 full hydraulic sonic frequency resonance drill combined with press-fitting sampling drilling tool was used for sampling in Liuchangying. The drilling technology and the problems may encountered in sampling process are mainly introduced in the paper with solutions. The future development of environmental sampling drilling technology is prospected.
