Abstract

An in-situ immobilization and stabilization apparatus for contaminated soil comprises a connecting base plate module disposed at the upper end of an arm structural frame of a blending arm, two fixed tubes inclining down are symmetrically arranged at the lower end of the arm structural frame, a hydraulic motor is fixed in each fixed tube, each hydraulic motor is connected with a rotating tube through a transmission device, the outer wall of each rotating tube is provided with a plurality of stirring blade plates spirally arranged. The blending arm specially made is used to efficiently cut, stir-throw and blend the soil, allowing three-dimensional multi-directional deep stirring; the rotating tubes (106) are used with the stirring blade plates spirally arranged, thus blending is effective, crushing capacity is high, torque is high, motion drag is small, and damage rarely occurs; during high-speed rotation, material of flow plasticity can be well blended; viscous drag of the soil is overcome, and the soil is homogenized.

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 device 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...
