The high-quality development of ecological civilization is inseparable from the protection and prevention of ecological animals and plants, and soil composition can reflect the problems of material circulation and ecological environment, that is, soil sampling is one of the important research fields of ecological environment and building construction. Sampling includes sampling arrangement and sampling techniques. The collection of section soil samples should be carried out after the section observation and recording is completed. Before sampling, the section should be refurbished and cleaned, the topmost floating soil should be cut off, and then the top layer should be taken from the top according to different depth levels. While sampling from the central typical part layer by layer, the soil sampling system needs to be used to go deep into the ground to collect the soil when sampling the soil. However, the structure of the existing soil sampling system is not perfect, and there are still certain defects:

When sampling, the soil is generally sampled by the manual hand-held sampling system and the machine. There are scales on the surface of the set, which can be recorded by observing the scales, but the scale records are prone to errors. If the scale lines are blurred, the measurement cannot be performed, resulting in missing sampling data and affecting the results of soil testing. If there is an unexpected situation during in-depth detection, there are too many internal gravel or hard barriers, which will cause damage to the system. When the system is damaged, the ground personnel cannot judge in time, resulting in local damage caused by excessive system extrusion force. Damage, not only affects the process of detection, but also causes the broken system to cause damage to the depths of the land, which has certain limitations.
