锚注加固技术在软岩巷道围岩加固中的应用研究

Study on the Application of Bolt Grouting Reinforcement Technology in Soft Rock Roadway Surrounding Rock Reinforcement

针对原支护对巷道两帮、底部的控制较弱,顶部强度也需要加强的情况。根据高预应力、高强度、高刚度、强力支护的支护加固理念,采用预应力高强锚索支护系统,配以围岩注浆、锚注技术,解决了巷道围岩控制问题,保证了巷道设计断面及其功能使用。工程实践表明修复加固方案能够满足巷道修复治理的要求,取得了很好的效果。

In view of the weak control of the original support to the two sides and the bottom of the roadway,the top strength also needs to be strengthened.According to the support and reinforcement concept of high prestress,high strength,high rigidity and strong support,the pre-stressed high-strength anchor cable support system with surrounding rock grouting and anchor grouting technology is adopted to solve the surrounding rock control problem of the roadway and ensure the design section and function use of the roadway.Engineering practice shows that the restoration and reinforcement scheme can meet the requirements of roadway restoration and treatment,and has achieved good results.
