Audited Supplier Shanshui Special R thread Self Drilling Anchor Bars R32S/18 C45 /45# self-drilling anchor hollow bars
Hollow anchor bar is the body of a self-drilling anchor, as a hollow steel tube with an outer round thread, hollow anchor has the sacrificial anchor bit connected at one side, plate and nut connected at the other; two hollow anchor bars could be connected together via a coupling, for duties that requiring longer anchors.
Product advantages
1. High construction efficiency: R32S/18 C45 /45# self-drilling anchor hollow bars can complete the construction with one drilling and grouting. It has few construction steps and high construction efficiency.
2.Strong adaptability: R32S/18 C45 /45# self-drilling anchor hollow bars can be drilled and grouted at one time without pulling out the drill pipe. It can still be constructed normally in broken surrounding rock. It can be applied to various types of surrounding rock and has stronger adaptability.
3.Low labor intensity: R32S/18 C45 /45# self-drilling anchor hollow bars can be constructed using an anchor drill, which is easier to mechanize and has less labor intensity than conventional pipe sheds.
4.High safety: Workers can stay away from the tunnel face during construction of the R32S/18 C45 /45# self-drilling anchor hollow bars , which are safer.
5. Low overall cost: Although the material cost of R32S/18 C45 /45# self-drilling anchor hollow bars are slightly higher than that of the conventional steel flower tube shed, its construction efficiency is high, it can adapt to various unpredictable surrounding rock conditions during tunnel construction, shorten the construction period, and also indirectly reduce the cost of the project. The cost of capital, equipment rental, etc. is eliminated, so the overall cost is lower
Features
• Stable quality;
• Thread is compatible with ISO and other international standards;
• Good mechanical performance.
Applications
Pre-supporting, micropiling for foundation underpinning, slope anchorage, etc.
