副井井壁断裂注浆加固工程实践

Shaft Wall Breakage Grouting Firming Project Practices at Subsidiary

通过副井井壁断裂破坏机理分析,利用以前井筒处理的经验确定治理方案,选择注浆材料和设计参数,采用破壁注浆法。

Through analysis on theory of subsidiary shaft wall breakage, with the former shaft treatment experience, treatment plan is defined. After choose of the grouting material and design parameter, wall breakage grouting method is adopted, with grouting layout and number of holes be reasonably confirmed, wall breakage and water leakage be effectively treated.
