R32 High Wear Resistance Ibo Hollow Rock Bolt For Railway Construction

The anchor body of hollow anchor adopts hollow design, the hole in the body is used as a channel for drilling high pressure wind and water and grouting channel, compared with solid body, the design of hollow body can get better stiffness and shear strength. The outer surface of the anchor body has a full-length standard large pitch threaded structure, which is easy for cutting and lengthening of the anchor, and increases the bonding area between the anchor body and the grouting material compared with the smooth body, thus improving the anchoring force.

1, Anchor head: The barbs on the anchor head can locate the anchor in the drilled hole and ensure the rod is well centered.
2,Body:the most important component in the assembly, playing 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 the gap in the surrounding rock.

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

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

1,Clean up the well by drilling with a drilling rig according to the design requirements.

2,Insert the hollow grouting anchor phase with installed anchor head into the
3,Install the grout stopper, gasket and nut.

4,Connect the grouting machine to grout.

5,The grouting should be adjusted according to the design requirements of the pressure.

Fields of application
Foundation and Foundation Engineering

Self-drilling anchors are mainly used in foundation and foundation engineering for projects such as foundation reinforcement, wind tower foundation, coastal protection, building foundation replacement, anti-floating, bridge deck reinforcement, retaining wall foundation, dam consolidation grouting and so on.
Foundation replacement, anti-floating, bridge deck reinforcement, retaining wall foundation, dam consolidation grouting and other projects.

Slope Project

Self-drilling anchors are mainly used for slope stabilization, rockfall protection, retaining wall stabilization, embankment stabilization, road damage disaster reinforcement, and water damage disaster protection.
riparian valley reinforcement, water damage disaster rapid repair and other projects.

Tunnel and Underground Engineering

Self-drilling anchors are mainly used in tunnel and underground projects for tunnel entrance pipe shed support, overrun pipe shed support, locking
footing support, roof support, system anchors and other projects.
