slope protection Comparative Analysis of Crawler Drilling Rig and Hand-held DTH Drilling Slope Bolt Hole Formation In recent years, bolt (anchor cable) support has been widely used in anchor protection of subgrade slopes and underground engineering. In the past, the construction of bolts (anchor cables) generally used hand-held down-the-hole drills (air leg rock drills) to form holes. Hand-held down-the-hole
overseas engineering projects Analysis of Overseas Engineering Equipment Management from the Perspective of TY-X5 Down-the-hole Drilling Rig Failure Maintenance In the process of vigorously promoting the "Belt and Road" policy in my country, more and more engineering contracting companies have responded to the call of "going global" and participated in the competition in the international market. It has become a new normal for construction companies to
tunnel Application of one-time Excavation Technology for Full-section Tunnel with Invert Taking a single-track tunnel of a plateau railway as the research background, the full-section with invert one-time excavation technology was studied in the weak surrounding rock section, which saved resources and avoided many problems caused by the secondary blasting of the traditional invert. The
