Sinorock Expansion Shell Anchor Bolt

Expansion Shell Anchor Bolt is by the composition of Expansion shell head,bit, steel anchor bar, plate, nut.Expansion Shell Anchor Bolt of Luoyang sinorock can overcome the short of anchor length and the low defects of the anchoring force .
Shell bolt anchor grouting and hollow prestressed composite reinforcement under the action of effective implementation of pressure grouting, after grouting on the surface of the weak mechanical properties, expansion shell anchor can improve crack cohesive force and internal friction Angle,increase the resistance of the relative displacement between internal block rock mass,make the broken rock cemented into a whole again,forming the bearing structure,
to improve the overall stability of surrounding rock, give full play to the ability of the stability of surrounding rock and at the same time the roadway support work together ,
Reduce stent under load;Additional concretion body closed fractures,effectively prevent moisture immersed within rock mass, prevent water disasters and weathering, keep the surrounding rock mechanics properties, achieve long-term stability of surrounding rock.To get more information please click:http://www.sinorockbolt.com/
