Development of a Suitable Operation Procedure for Electroosmotic Chemical Soil Improvement
To expand the improvement region, a series of electroosmotic chemical tests was performed to study the mechanism of improvement. Results showed that injection of calcium chloride and sodium silicate solutions could improve the soil near the cathode and anode, respectively. Injection of calcium chloride solution for a rational injection time, followed by the injection of sodium silicate solution, could yield a fairly good improvement result for the entire sample. The rational time for the injection of calcium chloride solution could be obtained by selecting the time between the first and second turning points on the relational curve of total drained water volume and injection time. Moreover, appropriate concentrations of injected solutions were studied and were discussed in this paper.
