Description

Self Drilling Anchor System

Self drilling anchor system consists of hollow anchor bar, nut, plate, coupler, centralizer and drill bit it can combine drilling, grouting and anchoring, functions together, which is suitable for broken rock and surrounding rocks which are difficult to drill holes, Without using casing pipe, it can greatly im. prove the construction efficiency, shorten the construction period and reduce the overall construc. tion cost. The hollow anchor bar can be cut anywhere and lengthened by the coupler, therefore, it is suitable for the construction in narrow space which the large equipment can not enter. Self-drilling anchor system can be used for slope stabilization, foundation support, tunnel pipe roofing, transmis- sion tower, wind tower foundation support, existing building repair and reinforcement, etc.

Hollow Anchor Bar

Left-handed and right-handed thread can be customized based on specific requirements.
