Hollow Bar Anchor/Self Drilling Anchor Bolt for Slope Stabilization T76n Steel 40cr/45

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:
1. Hollow design realizes the function of grouting pipe and avoids the loss of mortar caused by the traditional grouting pipe.
2. Grouting is full, and pressure grouting can be realized to improve the quality of the project.
3. Neutrality is good, the mortar can wrap the entire length of the anchor body to avoid rust and achieve long-term support.
4. It is easy to install, and it is convenient to install the plate and nut without machining the thread on site.
Application:
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.
Drill bits, nut, plate and coupler, etc.will be accembled accordingly.
