A curing agent slurry preparation device, a curing agent slurry preparation method, and a fluidized solidified soil production method

PendingCN122232049AMixing operation control apparatusControl apparatus
This invention discloses a curing agent slurry preparation device, a curing agent slurry preparation method, and a fluidized solidified soil production method. In the preparation method, a weight sensor collects the weight change curve in real time during auger feeding, identifies the excess material discharge, and calculates the correction value for the next batch's shutdown advance. Water is injected and preliminary mixing is performed. The slurry is injected into the lower mixing chamber. After adjustment according to the correction value, the next batch is prepared. During the lower mixing, the torque of the second agitator is collected, a rheological curve is fitted, and the homogeneity is determined to be up to standard after the torque fluctuation rate is below a threshold and maintained for a set time, at which point the material is discharged. The upper and lower layers operate alternately in parallel cycles. The fluidized solidified soil production method of this invention includes: excavating a mud pit nearby and mixing it into mud; preparing the curing agent slurry using the above method; and pumping the slurry to the mud pit and mixing it into fluidized solidified soil. This invention employs a "two-step" process to prepare the curing agent and fluidized solidified soil in stages, avoiding long-distance transportation of the finished solidified soil and improving construction efficiency and the stability of the solidified soil quality.
