Soil in-situ remediation integrated device

Abstract

The invention provides a soil in-situ remediation integrated device. The soil in-situ remediation integrated device comprises a moving mechanism, a shallow soil remediation unit, a deep soil remediation unit, and a liquid agent bin, a solid agent powder bin, an agent mixing mechanism and a power control assembly which are arranged on the moving mechanism. The liquid agent bin is communicated with the agent mixing mechanism, and the solid agent powder bin is communicated with the agent mixing mechanism. The shallow soil remediation unit comprises a soil turning part and an agent split-flow spraying assembly. The deep soil remediation unit comprises a booster pump and a plurality of self-rotating agent spray needles, each self-rotating agent spray needle comprises a self-rotating spray head, each self-rotating spray head comprises an even number of spray nozzles, the projection of any two opposite spray nozzles on the vertical plane is W-shaped, and the projection of any two opposite spray nozzles on the horizontal plane is S-shaped. According to the invention, integrated remediation of shallow soil and deep soil can be realized, and the remediation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to an integrated device for in-situ remediation of soil. Background technique [0002] According to the characteristics and differences of deep soil and shallow soil remediation, it is necessary to design an integrated soil in-situ remediation equipment with special structures for deep soil remediation and shallow soil remediation. However, the existing soil in-situ remediation equipment does not have a special structural design, and the deep soil remediation mode is adopted when both deep soil remediation and shallow soil remediation are required. In the specific restoration of deep soil, it is necessary to dig the injection well first, and then inject the agent into the injection well. Due to the excavation of injection wells, not only are there many procedures and high repair costs, but the repair process is not fast and convenient, and the repair efficiency is low, so ...

AI Technical Summary

Problems solved by technology

However, the existing soil in-situ remediation equipment is not equipped with a medicament mixing mechanism for ready-to-use solid medicament powder and liquid medicament

If the manual preparation of liquid mixed agents is used at the job site, the operation process will be cumbersome, time-consuming and labor-intensive, and the repair efficiency will be low

[0004] To sum up, there is an urgent need for an integrated device for soil in-situ remediation to solve the soil remediation process caused by the lack of special structural design for deep soil remediation and shallow soil remediation and the absence of an agent mixing mechanism in the prior art. The problem of cumbersome and low soil remediation efficiency
