鄂北水资源配置工程取水竖井加固技术研究

Study on Reinforcement Technology of Intake Shaft in North Hubei Water Resources Allocation Project

针对鄂北水资源配置工程取水竖井岩体滑塌情况,分析了滑塌的原因及处理的技术难点,提出了加固方案和具体加固措施。通过利用岩体和锚杆作为支挡结构,利用钢围檩和钢支撑作为支撑体系,保证了进口取水竖井在渗漏风险大、加固空间狭小、加固安全风险大等诸多不利情况下的稳定,为类似竖井加固提供了新的思路。

In view of the rock mass collapse of the intake shaft in North Hubei water resources allocation project,the reasons for the collapse and the technical difficulties in the treatment are analyzed,and the reinforcement scheme and specific reinforcement measures are proposed.By using the rock mass and anchor rod as the retaining structure,and using the steel purlin and steel support as the supporting system,the stability of the imported intake shaft is ensured under many adverse conditions such as high leakage risk,narrow reinforcement space,and high reinforcement safety risk,which provides a new idea for the reinforcement of similar shafts.
