混凝土强度检测在井筒支护中的应用

Application of concrete strength testing technology in shaft support

运用无损回弹测试方法 ,对井筒支护的强度进行现场检测 ,并依据测试结果运用数值分析的方法 ,对井筒安全稳定性进行分析。采取了加固补强的具体措施保证了东主井在一定时期内的安全生产。

The on-site tests on the strength of shaft support were conducted by means of nondestructive rebound method. Based on the testing results, the security and stability of the shaft were analysed with the numerical analysis method. The concrete measures of consolidation and reinforcement for the shaft were taken so as to ensure the safety in production of the main shaft in a certain period.
