摘要
隧道极其破碎兼涌水段围岩施工一直是影响隧道施工安全及进度的重要因素之一,自进式锚杆代替超前小导管,是保证隧道施工安全及进度的方法之一,本文详细阐述了自进式锚杆施工工艺,为今后隧道破碎围岩及涌水围岩段施工提供了经验。
The construction of tunnel and its broken and water surrounding rock has always been one of the important factors that affect the tunnel construction safety and schedule. To replace the advanced small pipe with self advancing anchor bolt is one of the ways to ensure the safety of tunnel construction and schedule. This article elaborates the construction craft of self advancing anchor holt, which can provide reference for the tunnel broken surrounding rock and water burst surrounding rock construction in the future.
