Abstract

The invention discloses a contaminated soil in-situ solidification stabilizing treatment system and method. A hydraulic excavator main machine with a matched main machine and a hydraulic excavator main machine in a data monitoring system are connected with an even-mixing arm through a connecting base plate. Two fixed cylinder bodies which are arranged in a tilting-down mode are symmetrically arranged at the lower end of the even-mixing arm. Hydraulic motors are fixedly arranged inside the fixed cylinder bodies. The hydraulic motors are connected with rotating cylinder bodies through transmission devices. A plurality of stirring cutter boards which are arranged in a spiral-line mode are arranged on the outer walls of the rotating cylinder bodies. A compound air control material supplying device is connected with a medicament supplying device through a medicament supplying pipeline, a data cable, a multiphase flow conversion device and a medicament conveying system. Compared with the prior art, the contaminated soil in-situ solidification stabilizing treatment system and method have the advantages that the complete set of technological process is simple, rapid and reliable, the system devices are safe and reliable in structure, the even-mixing and stirring transmission efficiency is high, the torque is large, the stirring is even, the efficiency is high, quantification is achieved, the cost is saved, the depth is adjustable, the working range is expanded, and the automation degree is high.

Description

technical field [0001] The invention relates to the technical field of remediation of contaminated soil, safe disposal of river and lake dredging sludge and sewage treatment plant sludge, in-situ solidification, stabilization and safe disposal of sludge pits in landfills and soft foundations. In particular, an in-situ solidification and stabilization treatment system for polluted soil. Background technique [0002] The ecological safety treatment and disposal of sludge and sludge is a major environmental problem that needs to be solved urgently in my country. Some domestic sludge is buried in landfills. Strong water, low permeability coefficient, low shear strength, internal friction angle close to zero, and strong rheology, which makes the landfill work surface easy to form swamps, which makes the landfill work surface unable to be compacted, which seriously affects the landfill. The normal operation of the field and the surrounding ecological environment. [0003] The slud...
