Description

A rock sampler for geotechnical engineering

Technical Field

The utility model relates to the field of rock and soil sampling, and more specifically, to a rock sampler for geotechnical engineering.

Background Art

In geotechnical engineering, it is often necessary to survey the soil or rock to determine whether it is convenient to carry out construction at the survey location. When surveying the soil or rock, it is necessary to sample the soil and rock. When sampling, sampling is generally performed through a rock sampler. Existing soil and rock samplers generally cannot select the sampling structure according to the soil conditions at the sampling location. The existing sampling structure is single, which makes it inconvenient to sample soil and rocks with different soil conditions. At the same time, when sampling the soil or rock, it is necessary to perform multiple samplings at one location. Before the sampler is extended into the soil, the soil needs to be drilled. The existing sampler can only drill first, then sample, and then drill again before sampling again. Therefore, the sampling efficiency is low, which affects the sampling time of rocks, etc., and is inconvenient to use the sampler.
