Self-drilling Hollow Anchor Bolt

Special Drilling Rig for Self-drilling Anchor Bolts

Application Cases

Foundation Pit Support for Binjiang West Road Pedestrian Street, Tunxi, Huangshan

　　This project used Hengnuo R38 self-drilling hollow anchor bolts. The rod body is used as a drill pipe to achieve simultaneous drilling and grouting, and it is not pulled out after drilling, so it can serve as the anchor bolt tendon. Compared with the construction of steel bar anchor bolts, the grouting process is omitted, and the construction efficiency is increased by more than 5 times, which has been highly recognized by the construction party.

　　Drilling rig: HYZ133-100A special drilling rig for self-drilling anchor bolts

　　Construction efficiency: The average pure drilling time for a single hole (18m hole depth) is 14 minutes, and the drilling length per shift (8 hours) is more than 300m.
