Description

Technical Field

[0001] The utility model relates to the technical field of soil pollution prevention and control, in particular to a soil quantitative filling and layered compacting device. Background Art

[0002] Soil pollution is characterized by its long-term, non-degradable and cumulative nature. Excessive pollutants in cultivated soil may pose a serious threat to the ecological environment, agricultural product safety and human health through migration and diffusion in various environmental media and transmission in the food chain.

[0003] For a long time, the remediation of cultivated land soil pollution has usually adopted chemical, physical and biological technologies and methods to reduce the concentration of pollutants in the soil, fix soil pollutants, convert soil pollutants into low-toxic or non-toxic substances, and block the transfer pathways of soil pollutants in the ecosystem. The main technologies are passivation / stabilization, low-accumulation variety planting, plant extraction technology and mild physical and chemical reduction remediation technology. However, most of the remediation technologies are still carried out in the laboratory through centrifuge tubes or potted scales for single pollutant soil remediation batch tests. These tests use small amounts of soil, small scales, and lack the remediation effects, migration laws and removal mechanisms under the mutual influence of multiple pollutants. There may be great differences between the soil cleaning and remediation effects and applicability in the field. Although some existing remediation technologies, such as plant remediation technologies that can reduce the amount of heavy metal contaminated soil, have been tested in the field, field remediation has problems such as long remediation cycles, susceptibility to biogeographic climate restrictions, and poor pollutant remediation effects. At present, the lack of relatively large-scale pilot tests and simulation devices between laboratory batch tests and field actual application large tests has led to the results of small-scale pollutant removal tests often being unable to be actually applied in the field. The pilot test phase can simulate and study a certain scale of contaminated soil, thereby ensuring the actual effect of composite contaminated soil remediation in the field. In existing laboratory tests, the filling and compaction of contaminated soil are mostly done manually, where compaction is done manually with a compaction hammer. For the pilot test phase, the labor intensity is high. Therefore, it is necessary to set up a soil quantitative filling and layered compaction device to meet the requirements of the pilot test phase for filling the contaminated soil into the sandbox and achieve high-precision simulation of natural soil density, reduce the labor intensity, and thus ensure the accuracy of the test simulation results.
