Polluted soil compaction process

The invention provides a polluted soil compaction process which comprises the following steps: S1) mixing and stirring: conveying polluted soil and auxiliary materials into a stirring assembly, and stirring by using the stirring assembly to form a mixture; s2) mold preliminary compaction: feeding the mixed material into a mold through a transmission assembly in a material leakage manner, and pressurizing for preliminary compaction to obtain a preliminary pre-pressed block; and S3) repeated compaction in a thermal shrinkage furnace: placing the pre-pressed block in a shrinkage packaging assembly, and repeatedly performing thermal shrinkage and coating on the pre-pressed block in a heating and coating manner to form a compacted block. According to the method, the polluted soil is repeatedly subjected to heat shrinkage and then coated, so that the compactness of the whole compaction block is improved, and the compaction block is prevented from loosening. 本发明提供污染土压实工艺，包括以下步骤，S1)混合搅拌：将污染土与辅料输送至搅拌组件中，利用搅拌组件进行搅拌，形成混
