AI Technical Summary

Technical Problem

Traditional borehole sampling techniques cannot effectively address the problem of cross-mixing of water samples from different layers in deep and multi-layered aquifers, resulting in insufficient sampling accuracy and failing to meet the needs of geotechnical engineering and environmental monitoring.

Method used

A multi-layer groundwater continuous sampling device is adopted. Through the support-type sampling mechanism and the drilling sampling mechanism, an independent and closed sampling space is constructed using a support isolation kit composed of a bottom isolation tube and stacked isolation tubes. This achieves physical isolation of water samples from different depths, and precise sampling is carried out by forming an inlet window through axial separation of the stacked isolation tubes.

Benefits of technology

It achieves a true reflection of water samples at different depths, improves sampling accuracy, avoids water sample mixing, improves sampling efficiency, and meets the requirements for sample authenticity and accuracy in deep and multi-layer aquifer sampling.
