Synchronous grouting in shield tunnel construction plays a critical role enhancing impermeability, ensuring precise alignment of segment rings, and mitigating surface settlement. Despite its importance, limited research has been conducted on the visualization numerical simulations for behind wall. This study addresses this gap by simulating diffusion process during post-grouting using CFDEM software. The simulation results reveal that grout injected from upper opening initially diffuses hemispherical pattern centered at injection point subsequently migrates downward along outer diameter under influence gravity. Conversely, lower outlet rapidly fills annular transitions to permeation phase. At volume 100%, slurry coverage area reaches 62.5%, with waste 37.4%. When increases 200%, marginally improves 73.1%. Balancing effectiveness costs, optimal effect is achieved as excessive will not be greatly improved leads substantial material waste. To achieve complete coverage, particularly unfilled regions head sides, secondary recommended instead further increasing initial volume. approach minimizes while maintaining efficiency.

With the increasing number of anti-seepage reinforcement projects and continuous improvement quality requirements, high-performance green requirements have also been put forward for grouting materials. Traditional karst cave mainly uses cement-based materials, which not only high carbon emissions but do comply with sustainable development strategy regard to being green, low-carbon, environmentally friendly. A material made by mixing a slurry B is proposed in this paper. The solid phase composed stone powder bentonite, an anti-washout admixture necessary. Slurry suspension thickener (CMC or HPMC) anhydrous ethanol. By two slurries evenly, obtained. Experiments were used investigate ideal ratios powder, water A, ratio ethanol B, analyze evolution apparent viscosity after mixing. This study revealed that optimum bentonite was 4:1, most reasonable water–solid 0.8:1.0. CMC HPMC 5:1. added at rate 5~10% obtain best properties. mixed would disperse even flowing could harden consolidate quickly. strength consolidation body close wet soil, can meet tunnel construction.

Currently, perfusing deceleration aggregate is the most effective way to create water-blocking sections for controlling coal mine water inrush disasters. Clarifying two-phase coupling migration mechanism of and in channels key quantitatively determining deposition distance after entering channel from perfusion hole. Based on fluid mechanics, slurry pipeline transportation theory sediment dynamics, this paper categories entire process hole into three motion stages: free fall, curved-throwing, sliding. The force characteristics each stage are analyzed, a theoretical model single-aggregate sedimentary established. CFD-DEM method used establish transient bidirectional numerical calculation aggregate-water verify (overall error not exceeding 10%). Finally, based research, reasonable suggestions proposed actual engineering plugging by aggregate.
