超高渗透压力和超大流量条件下灌浆材料性能研究与应用

Research and application of grouting material performance under the condition of super-high osmotic pressure and super-large flow rate condition

超高渗透压力及超大流量条件下,隧洞工程的防渗技术研究具有重要意义。本文以锦屏二级水电站高压涌水处理方案为例,通过对膏状可控浆液、ch聚丙烯酰胺浆液、金沙浆环保型防渗加固浆液等特殊灌浆材料的试验测定和数据分析,总结研究了该类灌浆材料的特性和使用条件,对山区复杂环境条件下的类似工程提供了较好的借鉴意义。

Study of anti-seepage technology for tunnel project under the condition of super-high osmotic pressure and super-large flow rate has great significance.High pressure water treatment scheme in Jinping Stage II Hydropower Station is adopted as an example.Properties and use conditions of the grouting materials are summarized and studied through test measurement and data analysis on special grouting materials such as paste controllable grout,ch-polyacrylamide grout, Jinsha mortar environmental protection anti-seepage reinforcement grout,etc.Better reference meaning is provided for similar projects under the condition of complex environment in mountainous area.
