AI Technical Summary
Existing in-situ solidification technologies for treating riverbed sediments suffer from problems such as poor addition accuracy, low efficiency, low automation, and the ease with which pollutants can spread during the addition process.
An in-situ solidification treatment system for riverbed sediment was designed, comprising a support platform, a solidifying agent storage and transportation unit, a feeding unit, a depth adjustment unit, a mixing unit, and a control unit. The system uses components such as a metering pump, a distribution plate, a feeding pipe, a distance sensor, and an electric push rod to achieve uniform and quantitative addition and uniform mixing of the solidifying agent, and prevents the spread of pollutants through a surge shield.
It improves the uniformity and precision of solidifying agent application, reduces pollutant diffusion, increases work efficiency, ensures uniform mixing of solidifying agent and bottom sediment, forms a stable hard shell layer, and protects the aquatic environment.
