Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling, in particular to a soil sampling device for highway detection. Background Art

[0002] When building a highway, it is very important to sample and test the soil. Testing the soil's density, moisture content, particle size, etc. can help engineers evaluate the soil's bearing capacity and stability, analyze the soil's pH value, organic matter content, and the presence of pollutants (such as heavy metals, oil, etc.), and ensure that the soil is suitable for construction and will not affect construction materials and the surrounding environment. Through soil test data, engineers can develop appropriate foundation design plans to ensure the long-term stability and safety of the highway. Different types of soil require different construction technologies and methods. The test results can guide construction personnel to make reasonable arrangements. Soil sampling and testing are important components of pavement design, construction, and maintenance.
