Friction bolt is a full length anchorage, actively reinforce the surrounding rock of the new bolt, it is a vertical slit three-dimensional parts high strength steel tube, when installed on pipe diameter smaller than the hole, can immediately within the scope of the length of the radial pressure and prevent the surrounding rock of hole wall in friction, plus plate bolt tray retainer force, so that to stress state of surrounding rock in the three and achieve stable rock formations. Under the blasting vibration of rock anchor to move, and so on and so forth, later the anchoring force are increased obviously, when the displacement of surrounding rock of significant, does not lose its anchor supporting force, it than shell bolt has better properties.

Before installation, the hole position of the bolt should be determined according to the design requirements. The hole should be drilled with the drilling rig, and the rock powder in the hole should be blown out by the pressure wind. The bolt body is equipped with an anchor plate and the bolt is driven into the hole with a percussive drill. Friction bolt installation, seam pipe bolt installed on pipe diameter smaller than the hole, then, would impose three force on surrounding rock, one is in the friction bolt length range of radial stress of hole wall, is a kind of friction, to prevent rock fall, another is the retainer plate friction bolt tray. These three forces make the surrounding rock more stable.

The company not only produces and sells friction bolt, but also mining anchor network such as Welded wire mesh,diamond network. In the company's business scope, there are also anchor bolt support, bracket support and other related products. The company runs the support products deep ploughing support industry, in the industry to do a good job of their own, good customer service. Can make the customer trust and rest assured.
