Advantages of the self-drilling type hollow anchor bar
1. The combination of form a complete set of special bolt and grouting process, grouting pump is one of the tribes of alone has solved the traditional anchorage support many topics of anchorage system.
2. The installation, then, do not need the scene processing thread, can install to plate and nut.
3. The grouting plump, and can realize the pressure grouting, progress the project quality.
4. The hollow design, make the anchor realized the function of injection pipe, avoid the traditional construction technology of grouting tube of the loss of slurry comes out
.5. Because the role of various accessories, neutral in rod body is very good, mortar anchor rod body length can be package, avoid the risk of rust, achieve the goal of the long-term support.
