AI Technical Summary
Existing technologies for geotechnical engineering investigations involve high costs for in-situ sampling and testing, significant disturbance to the soil at the test location, and inaccurate test results.
An underground soil sampling and testing system is adopted, including an end effector, a delivery assembly, and a climbing frame. The end effector can perform horizontal sampling or testing by connecting multiple sections of the rod with unidirectional folding joints, thereby reducing the construction difficulty and collapse risk of the operating hole.
It reduces the construction difficulty and collapse risk of the operating hole, improves the accuracy of test results, simplifies the structure of the execution unit, and enhances the versatility of the system.
