- Abstract:
- Pre-grouting reinforcement was a common pattern in subway construction. The grouting model test equipment with an assembly of stable pressurization system, model box system and grouting system was developed to study diffusion and distribution of slurry in pre-grouting projects. Sodium EDTA titration method was improved to detect the cement content in cement soil. And this was combined with cutting samples in the range of the grouting influence to develop a block titration method and implement a complete grouting test. Results showed that the grouting model test equipment worked well, improved sodium EDTA titration method can detect the cement content in cement soil accurately, a visually clearer and more presentable distribution and diffusion range of slurry can be obtained by block titration method, a reasonable and feasible test method has been established to study the distribution of slurry for similar tests..
