摘要
通过对北京铁路地下直径线带压进仓换刀工程实例的分析,探讨了注浆加固及桩基加固在地层加固中的应用,分析了带压进仓的漏气原因并采取相应的应对措施,保证了盾构的正常施工。
Based on the engineering example of underground diameter project replacing the cutter teeth inside with high pressure, the application of grouting reinforcement and pile foundation reinforcement in soil strengthening was discussed. The causes of gas leakage of inside with high pressure were analyzed, and the countermeasures were proposed for assuring the normal construction of shield.
