The construction method of self drilling anchor system

The self drilling anchor system  crusher is mainly used in complicated conditions, weak surrounding rock, highland stress large deformation, were support, rescue, landslides and other self-governance Drilling and Grouting in all cases, for a wide range of higher functions.
After it is installed in the hollow bolt head on the body of carbide drill bits, drill pipe with the bolt body instead of drilling shank connected to the connecting rod bolt body and drilling machine, drilling machine with a bolt hole to the depth to the design, installation pulp stopper, plate, after nut, grouting, when the slope support or hydropower construction, can also be used instead of the large-diameter bolt hole drilling drill pipe, drilling grouting,and play more powerful role than anchor,it is stronger, quicker and more convenient and lower construction costs.
