Description
Technical Field
[0001] This utility model belongs to the field of geotechnical sampling technology, specifically a drilling sampler used for geotechnical engineering exploration. Background Technology
[0002] Geotechnical engineering investigation is a crucial preliminary task for various engineering projects. By drilling and sampling soil and rock using samplers, accurate geological data can be provided for engineering design and construction, offering strong support for the safety, stability, and economy of the project.
[0003] However, in reality, traditional drilling samplers used in geotechnical engineering investigations generate a large amount of dust during drilling due to the fracturing of soil and rock and the rotation of the drill bit. This dust easily mixes into the sampled soil and rock, affecting the purity and accuracy of the sample. Furthermore, traditional drilling samplers often lack effective filtration mechanisms, failing to separate the dust from the sample. This results in the sampled soil and rock still containing a large amount of impurities, reducing sample quality and affecting experimental data. Secondly, traditional drilling samplers used in geotechnical engineering investigations cannot collect the dust generated during drilling, which can easily cause unnecessary harm to the environment and human health, resulting in low safety.
