As an effective means of anchorage, self drilling rock anchoring system is widely used in tunnel pre-support, radial support, reinforcement, as well as tunnel disease treatment works. And the use of self drilling ground anchor has made a lot of good economic and social benefits.
The hollow threaded ground anchor bar is a sort of new construction technology that has been widely applied in the geological engineering and railway station project. And a large amounts of problems have been solved in the manufacturing process and it is well optimize to the poor ground conditions, such as loose soil, weak rocks, unsolidable layers and so on.
The use of Sinorock's self drilling rock anchoring system can meet the need of soil stabilization. Sinorock self drilling ground anchor makes slope stabilization better. The conventional method of installation involves drilling the hollow anchor bolt with air or water flush to the design depth, and then in a second phase, independent of drilling, a grout adapter is added and a cement based grout mix is injected through the hollow core to exit at the bottom of the borehole, and then return upwards to fill the annulus, thus providing once cured for the transfer of tension load from the soil/ rock formation to the anchor bolt.
