Suitable for various rock and soil geological conditions.
It performs particularly well in geological conditions where conventional anchor rod construction techniques are difficult to implement, such as in geology prone to borehole collapse;
Drilling depth is unrestricted.
Conventional anchor rods are limited to shallow depths due to existing material and drilling equipment constraints. Self-drilling anchors, however, overcome this limitation with minimal drilling resistance, enabling significantly greater depths. According to Zhongfu Mining Anchorage Project Reports, self-drilling anchors currently achieve drilling depths up to 18m;
Suitable for confined space construction
Individual self-drilling anchor rod lengths can be cut or extended as needed, with common specifications including 2m, 3m, 4m, and 6m;
Simplified process flow
Self-drilling anchors complete drilling, grouting, and anchoring in a single operation, streamlining procedures and accelerating construction speed;
Promotes borehole stability
During drilling, a screw grouting machine pressurizes and supplies cement slurry with a water-cement ratio of 0.4–0.5. This slurry rapidly fills the borehole and rock/soil fractures, solidifying as it is absorbed by the borehole walls to ensure stability.
