Production:

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 improve the construction efficiency, shorten the construction period and reduce the overall construction 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, transmission tower, wind tower foundation support, existing building repair and reinforcement, etc.
