摘要
介绍在锚索(杆)施工中采用履带钻机成孔,并通过新型的变角机构调整成孔角度,降低对工作面的要求,该技术具有施工精度高、速度快、施工工作面要求低、成孔角度大,钻进深度大等优点,值得推广应用。
This article describes the anchor(pole) used crawler rig into the hole in the construction.The pore angle is modulated by the new angle machine,so the working plane is lower requirement.This technology has lots advantages,such as high precision,fast speed,lower working plane requirements,larger drilling angle,drilling large depth,etc.,should be widely applied.
