Description

Technical Field

[0001] The utility model relates to the technical field of geotechnical engineering investigation, in particular to a portable sampling device for geotechnical engineering investigation. Background Art

[0002] Geotechnical engineering investigation usually involves monitoring of rock and soil, which generally includes technical contents such as sampling points, sample preparation, and analysis methods. Sampling devices are required to sample the monitored rock and soil.

[0003] When optimizing the existing portable sampling devices for geotechnical engineering surveys, most of them focus on solving the problem that the soil samplers are mostly one-piece cast structures. For example, the Chinese utility model patent with application number CN202221013329.8 discloses "A portable sampling device for geotechnical engineering". In this device, two handles are added and the handles are hinged to the hinge seat by a pin rod, thereby avoiding a rigid connection between the handles and the scale rod, making it convenient for the staff to turn the handles and adjust their angles. By turning the two handles, the two baffles can limit the angles of the two handles, so that the two handles can be made perpendicular to the scale rod, and the soil drill bit can be pressed into the soil by pressing down the two handles.

[0004] Although the above-mentioned portable sampling device for geotechnical engineering investigation has certain advantages in solving the problem that the soil sampler is mostly an integrated casting structure, it still has certain disadvantages: since the existing portable sampling device uses a spiral rod to extract the soil during soil sampling, the collected soil is spirally rolled into the sampling collection column shell, and the spiral rod and the wall surface of the sampling collection column shell are not conducive to cleaning after the sampling is completed, resulting in other soil remaining inside the sampling collection column shell during the next sampling process, causing the new sampled soil to mix with the old soil, affecting the accuracy of geotechnical investigation.
