浅谈超前管棚支护技术在海新三号隧道的应用

Application of the advance pipe roof support technology in Haixin No.3 Tunnel

本文介绍了在地质条件恶劣的海新三号隧道工程中采用超前管棚支护技术施工方案,有效避免因围岩浅埋偏压、岩体结构破碎段的坍塌事故,保障了施工安全,论证了该施工方案在实际运用中的价值。

This paper introduces the construction scheme of the advanced pipe shed support technology in the Haixin No.3 tunnel project with poor geological conditions,effectively avoiding the collapse accident caused by the shallow buried bias of the surrounding rock and the broken section of the rock mass structure,and ensuring the construction safety.It demonstrates the value of the construction plan in practical use.
