Description

A new in-situ shallow soil crushing and repairing device

technical field

The technical field of soil remediation of the present invention, in particular, relates to a novel in-situ shallow soil crushing and repairing device.

Background technique

At present, various common in-situ soil crushing and repairing devices mainly change the particle size of the soil and increase the degree of combination with the agent through strong cutting, rolling and other forms. Among the equipment currently used for remediation of heavy metal-contaminated soil on the site, for shallow soil, the typical reference for common in-situ soil crushing and remediation devices is the rotary tiller used in agricultural production. When performing soil crushing, the rotary tiller has high field leveling efficiency and strong soil breaking ability. After plowing, the ground surface is flat, which is also conducive to the uniform mixing with the soil after subsequent chemical spraying, which can effectively improve the ability of soil restoration. However, it should be noted that when encountering a polluted area with high soil viscosity, the degree of soil fragmentation by the rotary tiller is reduced, and the soil particle size is slightly larger. After spraying, the agent may only adhere to the lumpy soil The surface layer, the effect of soil remediation is not good.
