Self drilling rock anchor can effectively improve the load capacity and ensure the overall stability of surrounding rocks when applied to broken rock, clay rock and other complex geological conditions. Based on lots of practical applications, self drilling rock anchor has been proved to achieve the ideal supporting effect and has great application value.

To meet the needs of design and construction , a wide variety of self drilling anchors was used to support and protect these strata of rock, as well as to make radial reinforcement and slope stabilization. This measure significantly improved the performance of the surrounding rocks and demonstrated much higher efficient results of supporting.

Self drilling anchor is an anchorage measure to integrate drilling, grouting and anchoring functions. It has the advantages of fast speed, large anchoring force, good corrosion resistance and simple operation, etc. In the Jinhe Hydropower Station construction, R25 and R32 self drilling anchors were used for tunnel support and slope reinforcement. The application saved investment, accelerated the progress, ensured the anchoring quality of slope support and guaranteed the smooth completion of the project.
