摘要
介绍了锚索施工中埋钻的处理方法,通过改进钻头、反打、侧钻、改进钻杆、保守钻进,针对性地解决和避免了埋钻堵钻情况；还介绍了一些注浆方法的改进,旨在解决严重漏浆情况和使锚固段注浆更充分。
The problem of anchor cable drilling is most difficult in anchor cable construction. This article mainly introduces the processing method to deal with drill burying and core blockage through drill bit and drill pipes improving, inversing drilling, sidetrack drilling and conservative drilling. Some methods for improving the grouting is also introduced to solve the problem of fluid leaking and make the injecting of anchoring section more sufficiency.
