Description

Technical Field

[0001] The utility model belongs to the technical field related to geotechnical exploration, and more specifically, particularly relates to a geotechnical exploration sampling device with optimized anti-interference effect. Background Art

[0002] With the advancement of science and technology and the development of the engineering field, the requirements for the accuracy and effectiveness of geotechnical exploration data are increasing. In order to obtain more representative and accurate sampling results, traditional geotechnical exploration sampling is constantly being improved and optimized. However, traditional geotechnical exploration sampling equipment still has many problems. For example, traditional sampling equipment can only determine the depth of sampling by manual lifting or mechanical drilling, and the sampling tube of traditional equipment is prone to confusion when sampling, resulting in inaccuracy and low quality of sampled soil. In addition, traditional geotechnical exploration sampling equipment needs to make larger mounting frames and kits when sampling on slopes or steep slopes. Such an installation process will be time-consuming and costly, and will have a serious impact on the progress of the project.

[0003] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a geotechnical exploration sampling equipment with optimized anti-interference effect is provided, in order to achieve a more practical purpose. Utility Model Content

[0018] By slidingly installing a push plate inside the sampling tube, the sampled soil can be pushed out of the tube by a wooden stick at the end of sampling to ensure the integrity of the sampling.

The complete sampled soil can help engineers better analyze soil conditions, and this method can improve work efficiency. Compared with traditional manual methods, pushing the soil sample out of the tube by a wooden stick can complete the collection process faster and shorten the sampling time. Pushing the sampled soil by a wooden stick can reduce operational risks and avoid problems such as personal injury caused by operator errors. BRIEF DESCRIPTION OF THE DRAWINGS
