What are the advantages of hollow grouting anchor rods?
Hollow grouting anchor adopts hollow design, the hole in the rod body is used as drilling high pressure channel and injection channel, compared with solid rod body, the hollow rod body design has better rigidity and shear strength. Shandong China Coal anchor body outer surface full-length pitch threaded structure, the threaded structure makes the cutting and connection of the anchor body longer become easy, with the smooth anchor body and the bonding area of the injected material compared to the anchoring force. Compared with other anchors, it is easy to install and ensure that the prestressing force is applied in time. In terms of stretching, the pre-stressing force of the center-controlled grouting anchor reaches 50KN, which can realize the super-long stretching, and it is relatively easy to use, and one person can realize the operation of stretching, and it is also possible to realize the high-pressure injection through the hollow rod body to improve the surrounding rock.
