Chemical electroosmosis method is one of the fast and effective methods for soft ground treatment

which is widely accepted by engineers. In order to study the effect of reagent injection mixing ratio on chemical electroosmosis treatment of soft clay

model tests on electroosmotic were carried out

and the CaCl2 and Na2SiO3 solutions were combined to study the injection effect. The electroosmotic drainage effect was obtained when the ratio of the concentration of the substances was 1:1

1:2

1:3

2:1 and 3:1 respectively. The displacement

drainage rate and drainage microscopic characteristics of each working condition after the test (ICP-MS)

energy consumption

drainage effect

reinforcement effects

and uniformity were also discussed. The results show that when the concentration ratio of CaCl2 solution and Na2SiO3 solution was 1:1

the chemical electroosmosis effect is the best

the anodic corrosion amount is the least

and the energy consumption is the lowest. The electroosmotic effect is mainly influenced by the reagent injection ratio

specifically

by the type and quantity of cations added to the reagent

and the effect of Ca2+ on chemical electroosmosis is relatively prominent.
