Description

Technical Field

[0001] The invention relates to the technical field of soil sampling of landslide sliding belts, in particular to a soil sampling device of landslide sliding belts. Background Art

[0002] A landslide consists of a sliding mass, a sliding zone, and a sliding bed. The sliding zone is the key site of landslide occurrence. Under the influence of internal and external triggering factors, the sliding mass slides along the sliding zone, causing overall instability and failure. The sliding zone of a soil landslide is primarily composed of weak soil layers and muddy zones, typically ranging from a few millimeters to a few centimeters thick, distributed in strips along the slope along the downward direction. The physical and mechanical parameters of the sliding zone, such as the internal friction angle and cohesion, determine the stability of the slope. High-quality sliding zone soil sampling during landslide investigations is crucial to the accuracy of landslide stability assessment and the design of control projects.

[0003] Defects and shortcomings of existing technology:

[0004] During the drilling process, it is difficult to ensure the integrity of the soil sample during the lifting process after sampling because the soil layer near the sliding zone is loose; the sliding zone soil is thin and its depth in the slope is uncertain, so it is easy to drill through the sliding zone without taking a sample; a single borehole can only have one sampling position at the sliding zone, which limits the number of samples. Summary of the Invention

[0005] In order to solve the above-mentioned technical problem of soil sampling in landslide belts, the present invention provides a soil sampling device for landslide belts. The following technical solutions are adopted:

[0006] The cam is moved upwards to move the sampling rod upwards and downwards to move the sampling rod downwards. The cam is moved upwards and downward ...

[0007] The auger is then retracted and the auger is retracted, and the auger is retracted to the sampling hole ... The sampled soil is located within the sampling rod, preventing it from being disturbed or falling. Using the sidewall for sampling allows for additional sampling in unsampled boreholes, and multiple locations around the borehole wall can be selected for additional sampling, increasing the number of samples and resolving the issue of limited sampling in a single borehole.

[0010] By adopting the above technical solution and adding a transparent electric hatch assembly, the sampling hole can be opened and closed.

Workers can also manually select the sampling location. After sampling, the soil sample is located within the transparent electric hatch, isolated from the outside world, preventing it from being disturbed or falling.
