Description

[Technical field]

[0001] The utility model belongs to the technical field of soil detection, and in particular relates to a soil detection machine. [Background technology]

[0002] In engineering practice, we can determine the compressibility of soil through experiments, and use the obtained data to provide a basis for design and construction. For soils with high compressibility, we need to take corresponding measures, such as drainage and foundation reinforcement, to prevent possible problems such as foundation settlement. In existing soil testing technology, after sampling the soil, a soil testing machine is used to test the compressibility of the sampled soil. During the testing process, environmental factors will also affect the test data. For example, an increase in temperature will cause the compressibility of the soil to decrease. This is because an increase in temperature will cause water to evaporate, reducing the water content in the soil, thereby reducing the compressibility of the soil. However, the existing soil testing machine does not take environmental influences into account when conducting compression tests, resulting in inaccurate test data. [Contents of the utility model]

When testing is required, the soil sample is first placed in the testing mold, and the soil in the testing mold is tested for compressibility after the testing end of the testing mechanism passes through the outer heat preservation chamber and the inner heat preservation chamber. In the present application, the inner heat preservation chamber and the outer heat preservation chamber are sequentially covered outside the testing mold, which plays a double-layer insulation role, reduces the influence of temperature change on soil compressibility testing, and can also adjust the temperature of the outer heat preservation chamber and the inner heat preservation chamber through the temperature changing mechanism, so that the soil compressibility testing data is more accurate. Specifically, an electronic thermometer may be used to measure the temperature, and the measurement data may be fed back to the processor to drive the temperature changing mechanism 6 to adjust the temperature.

[0036] Specifically, the temperature changing mechanism 6 includes a cold source 61, and a first delivery pipe 62 and a second delivery pipe 63 respectively connecting the cold source 61 and the outer insulation bin 4.
