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

Hollow Grouting Anchor Product Details.

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.

It is suitable for the permanent support of surrounding rock with medium good geological conditions, as well as the overrun support of highway, railroad, tunnel, slope support, foundation pit support and other projects. Through the pressure grouting of the hollow anchor body, it can achieve the purpose of solidifying the broken rock body, isolating the groundwater and anticorrosion of the pole body, which can rapidly form the support force together with the rock body to control the stability of the surrounding rock, so as to achieve the purpose of good support.
