黏度时变性灌浆材料加固碎裂岩体应用研究
THE APPLICATION STUDY ON FRAGMENTATION ROCK REINFORCE-MENT OF AGEING STRENGTHENING MATERIAL GROUTING
摘要
Abstract
The ordinary cement slurry has long setting time , low early strength, and poor groutability.It is difficult to guarantee quality in the complex rock grouting .It proposes the ordinary cement slurry as the base mud slurry , and it put admixture in the ordinary cement slurry admixture to adjust the cement hydration and hardening process , which forms the SJP grouting material of variable viscosity in time .The slurry has good initial liquidity and initial low viscosity.The viscosity of the slurry can increase rapidly after the pump time , the size of the pump can be maintained in good time, the slurry setting time can be controlled to the initial setting time .The pump can pump over short time interval, which can reduce slurry erosion.The slurry consolidation has fast growth of early strength and high strength characteristics late.It changes the amount of an admixture , which can be formed with the formation of adaptable grouting material depending on the characteristics of rock formation .The application results show that for steep, wide joints and broken rock grouting, the grouting material variability has good suitability of SJP viscosity.The SJP viscosity can be used as anchor grouting material .It reduces the amount of material at the same time and can save cost and working hours .The perfusion quality meets the design requirements .Meanwhile the SJP grouting material also can be used in dam reinforcement , building foundation treatment, and geological disaster control engineering applications.关键词
