Description

technical field [0001] The invention belongs to the technical field of rock and soil sampling, in particular to a high-efficiency rock and soil sampling device and a sampling method thereof. Background technique [0002] Geotechnical is a collective term for rock and soil. Rock and soil can be subdivided into five categories: hard (hard rock), semi-hard (soft rock), weakly connected, loose and unconnected, and with special composition, structure, state and properties. It is customary in China to refer to the first two categories as rocks, and the latter three categories as soil, collectively referred to as "rock and soil". All kinds of projects above ground, underground and in water are collectively referred to as civil engineering. The part of civil engineering involving rock, soil, and groundwater is called geotechnical engineering. The strength, deformation and permeability properties of rocks and soils are determined experimentally. In the indoor test, the representa...

Problems solved by technology

[0004] (1) The existing high-efficiency sampling process of rock and soil obtains the loose coefficient by experience, for example, by referring to the loose coefficient of similar rock and soil, the accuracy is low, resulting in a certain gap between the actual unearthed amount and the theoretical unearthed amount; at the same time, for the The statistical analysis of rock and soil is not deeply applied, and the data interaction is insufficient. The data cannot be fully utilized to provide the corresponding geological body information, and it is impossible to provide comprehensive, effective and intuitive data support for engineering designers.

[0005] (2) In the prior art, the traditional algorithm is used to process the acquired image, which cannot effectively use the correlation of pixels to preprocess the image, which reduces the effect of segmentation and affects the analysis results of rock and soil

[0006] (3) In the prior art, the traditional algorithm is used to evaluate the soil slope stability of rock and soil. During the evaluation process, the accuracy rate of soil slope stability evaluation is reduced, and the modeling time is prolonged

[0007] (4) In the prior art, the traditional algorithm is used to search the landslide surface of the rock and soil based on the collected images and soil data, which cannot quickly obtain the sliding surface of the complex soil slope, and at the same time cannot be used for slope stability and engineering Reinforcement provides guidance
