摘要

摘要: 灌浆是解决工程渗漏问题的重要技术手段,堵漏材料是灌浆技术的核心。水泥浆液、水泥膏浆、速凝膏浆、改性沥青、低热沥青等非水反应型浆液是最常用的堵漏材料。根据浆液流变性质、在宽大孔（裂）隙中的扩散方式和封堵机理以及灌浆工艺参数建立了非水反应型灌浆材料的堵漏模型,对不同浆液在不同开度、不同流速地层的堵漏效率和堵漏效果进行了计算分析,可以为非水反应型浆液在堵漏工程中的选择使用提供依据。

Abstract: Grouting is the important technical means to solve the leakage problem, and the grouting material is the core of sealing technology. The slurries which do not react with water are generally used, such as cement slurry, cement paste slurry, quick-setting paste slurry, hot asphalt and low-thermal asphalt. A flow-water sealing model with a single channel macro-pore for the grouting material which does not react with water is established, based on the rheological properties of grouting slurry, diffusion in the macro-pore, sealing mechanism and grouting parameters. And then the sealing effect and efficiency of different slurries for the stratum with different flow velocities and gap-openings are simulated and calculated. The results can be used in the choice of the grouting slurries which do not react with water for the sealing engineering.
