Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering detection equipment, in particular to a civil engineering detection sampling device. Background Art

[0002] The sampling device for concrete in civil engineering generally rotates and presses down to move the sampling head into the pile body or concrete, and then extracts the core sample by suction or mechanical grasping. The commonly used coring drill is a hollow coring drill, which consists of a tubular shell and an internal sampling head. It can ensure that the core sample obtained by sampling is complete and not deformed. During the upward movement of the coring drill, the core block sample will move with it due to friction. However, due to the lack of a supporting component, the core block sample is prone to fall from the drill during the upward movement of the coring drill, damaging the core block sample. In order to solve the lack of support for the core block sample, a new type of civil engineering detection sampling device is needed. Utility Model Content
