Description

Technical Field

[0001] The present invention relates to the technical field of civil engineering, and particularly to a rapid soil sampling device for civil engineering. Background Technique

[0002] Soil is the main body of nature composed of mineral components with different thicknesses in layers. The differences between soil and the parent material layer are manifested in aspects such as morphology, physical properties, chemical properties, and mineralogical properties. Due to the interaction of the earth's crust, water vapor, atmosphere, and biosphere, the soil layer is different from the parent material layer. It is a mixed component of minerals and organic matter, existing in solid, gas, and liquid states. Loose soil particles combine to form a soil form full of gaps.

[0003] Civil engineering is a general term for the science and technology of constructing various engineering facilities. It refers to the technical activities such as the materials, equipment used, the surveys, designs, constructions, maintenance, and repairs carried out. In civil engineering projects, engineering geological exploration is indispensable. During the engineering geological exploration and survey work, it is necessary to take soil for testing. The traditional soil sampling device inserts the sampling cylinder into the soil by pressing the sampling cylinder body, and finally pulls out the sampling cylinder body to achieve sampling. Then, the material discharging plate in the sampling cylinder is pushed to push out the soil in the sampling cylinder. However, a pressing mechanism needs to be set up to push the pushing plate, and a pressing mechanism also needs to be set up to press the sampling cylinder body. The setting of the two pressing mechanisms increases the overall structure of the soil sampling device and the operation is relatively troublesome. Summary of the Invention
