An integrated device for soil in situ remediation

Abstract

The invention provides an integrated device for soil in-situ restoration, which includes a moving mechanism, a shallow soil restoration unit, a deep soil restoration unit, and a liquid medicament silo, a solid medicament powder silo, and a medicament mixing unit arranged on the moving mechanism. Mechanism and power control assembly; the liquid medicament silo communicates with the medicament mixing mechanism, and the solid medicament powder silo communicates with the medicament mixing mechanism; the shallow soil remediation unit includes a soil turning component and a medicament splitting spray assembly; the deep soil remediation The unit includes a booster pump and a plurality of spin medicament injection needles, the spin medicament injection needles include a spin spray head, and the spin spray head includes an even number of nozzles, for the projection of any two opposing nozzles on a vertical plane It is W-shaped, and the projection on the horizontal plane is S-shaped. The invention can realize integrated restoration of shallow soil and deep soil and improves restoration efficiency.

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
