Product Description

SELF-DRILLING Anchor Bolt

Self drilling anchor system for application in soil nailing, rock bolting, micro-pipling, tunneling, mining and infrastructure.

WHAT IS SELF-DRILLING ANCHOR SYSTEM?

Self drilling anchor system is a type of ground anchor used to provide stability in soil or rock formations. The system typically consists of a Hollow Anchor Bar with a drill bit on one end and a coupling on the other. During installation, the drill bit is used to bore a hole into the ground while simultaneously injecting grout into the hole to fill any voids. The anchor bar is then inserted into the hole and the grout is allowed to set, creating a bond between the anchor and the surrounding ground. This creates a stable foundation that can support a variety of structures and engineering projects. Self drilling anchor systems are commonly used in construction, mining, and tunneling applications.

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
