With strong penetrating drill bits,self drilling hollow anchor bolt can drill all kinds of rock

High-effect grouting fills cracks, solidifies rock and soil, and controls underground water, which has good grouting diffusion radius and reliable anchoring quality.
With strong penetrating drill bits,self drilling hollow anchor bolt can drill all kinds of rock.
Hollow anchor bolt doesn’t need to pull out, it can be used as grouting channel and grouts slurry.
Plug can keep strong grouting pressure, fill cracks adequately and fix broken rocks. Plate and nut can transmit stress to surrounding rocks evenly and achieve the goal of surrounding rocks and hollow anchor bolt support each other.

A majority of self drilling anchor system of Sinorock had positive effects on constructions includes mine,tunnel,foundation support project and anchoring performance over four years since established, echoing results from last year in a sample that is nearly three times as large.

Sinorock - self drilling anchor provide the optimal solution for nailing, bolting, micro piling and as ground anchors in difficult ground and rock conditions. The self drilling anchor system is manufactured with a cold deformed full length rolled thread as per standard and acts as the drill rod during the drilling operation. Once installed and grouted it converts into a very effective anchor. The use of this technology has the advantage that there is no need for cased drilling systems, which result in a simple installation method and economical savings on the project.

The self drilling anchor system of Sinorock has become an established tool in the industry for mining.Through innovation we have developed the simple and very effective self drilling anchor bolt system for supporting the mine in inaccessible places. Our expertise has stood us in well stead in a number of major long-term research projects.
