This paper introduces the structural principles and technical parameters of CB and ZB thin-walled earth borrowers. The influence of various parameters of thin-wall soil borrower structure on the quality of soil samples was analyzed. The performance comparison tests of conventional earth-borrowers and thin-walled earth-borers were described, and various influencing factors that caused the disturbance of soil samples were analyzed. Provides the basis for the production and improvement of thin wall earth extractors.
