Hollow bar anchor is pull rod that transfer anchored structures or geotechnical loads to a stable formation. Pressure grouting of the anchor bar through the hollow bar body can achieve the purpose of consolidating the broken rock mass, blocking the groundwater and the anti-corrosion of the rod body, and rapidly forming the supporting force to control the stability of the surrounding rock. It is widely used in tunnels, mining, slope stabilization and underground engineering support. Suitable for anchoring some loose geological structures (crushed, sandy and fragile soils). Hollow bar anchors are mainly produced by high-strength seamless pipes.
Features and advantages:The hollow bar anchor has been successfully applied in rock and soil anchoring engineering such as tunnel construction, slope treatment, foundation pit retaining wall and mining, and has achieved good economic benefits.
