摘要
超前支护是软弱围岩施工中常用的施工措施,结合洞湾隧道施工的实践,对超前管棚、超前注浆小导管等超前支护技术措施进行分析,总结该隧道施工中的成功经验,为采取同类施工措施的隧道施工提供参考。
Pre-support is commonly used in the construction of weak surrounding rock. Combined with the practice of hole-bay tunnel construction, analysis is made on the lead pipe shea, advance small pipe grouting technology, and the successful experiences are concluded which will provide a reference for similar construction.
