AI Technical Summary

Technical Problem

Existing in-situ soil sampling devices lack an effective isolation structure during the drilling process, causing loose soil particles to enter the sampling assembly, affecting the purity of the sample; the sampling operation relies on manual intervention and has a low degree of automation, making it difficult to achieve precise penetration of the sampling tank and the soil layer and automatic sampling; there is a lack of secondary isolation protection after sampling is completed, and the sample is easily contaminated by external factors, affecting the accuracy and reliability of geological exploration data.

Method used

The design adopts a combination of isolation plate and drive assembly. The sampling tank is isolated by the isolation plate on the lower side of the drill pipe to ensure the purity of the sample during the drilling process. After reaching the predetermined soil layer, the driving assembly drives the sampling tank to penetrate the soil layer, completing automatic lid closing and secondary isolation, reducing contamination during the lifting process.

Benefits of technology

It improves sampling efficiency and sample accuracy, prevents loose soil from entering the driving component, realizes automated sampling and sample protection, ensures the original state of undisturbed soil samples, and improves the accuracy and reliability of geological exploration data.

Abstract

The invention discloses an undisturbed soil sampling device for engineering geological exploration, and particularly relates to the technical field of sampling equipment.The undisturbed soil sampling device comprises a vehicle body, a sampling cabinet is fixedly installed at the upper end of the vehicle body, a supporting frame is fixedly connected to the bottom wall of an inner cavity of the sampling cabinet, and a driving motor, a drilling machine and a control cabinet are fixedly installed at the upper end of the supporting frame in sequence; sampling equipment is fixedly mounted at the lower end of the drilling machine. According to the undisturbed soil sampling device for engineering geological exploration, the sampling tank and the sampling assembly are isolated through the isolation disc arranged on the lower side of the drill rod, so that scattered soil particles are prevented from entering the driving assembly to influence the purity of a sample in the drilling process; the driving assembly is driven by the electric telescopic rod to drive the sampling assembly to sample undisturbed soil, automatic cover closing and secondary isolation are achieved through cooperation of the driving assembly, the sampling assembly and the isolation disc after sampling is completed, pollution to an undisturbed soil sample in the lifting process is reduced, and then the sampling efficiency and the sample collection precision are improved.
