Full Threaded Steel R51N Diameter 51mm Self Drilling Rock Bolt Hollow Anchor Bar Anchor Rods

The bolt body of the hollow bolt adopts hollow design, and the middle hole of the bolt body is used as the high pressure geomancy channel and the grouting channel. Compared with the solid bolt body, the design of the hollow bolt body can obtain better stiffness and shear strength. The total length of the external surface of the bolt is standard large-pitch thread structure, which is convenient for cutting and lengthening the bolt, and increases the bonding area between the bolt body and the grouting material compared with the smooth slide rod body, thus improving the anchoring force.

1,Anchor head:The barbs on the anchor head can locate the anchor rod in the drilled hole and ensure the rod is well centered.

2, Anchor body: the construction in the assembly, plays a major role in anchoring and support.

3,Stop-plug:keep the grouting pressure during the grouting process, so that the slurry can fully fill into the gap of the surrounding rock.

4,Pad:to withstand the greater stress of the surrounding rock.

5,Nut:centralize the stress of surrounding rock to the pad.
