3. The Jambo is equipped with a tensioning mechanism to pull out the anchor rod and then lock the backing plate and nut to apply prestress.

4. R25 built-in resin anchor test results: head pull-out force >78kN  after resin mixing one minute.

5. Advantages of built-in resin anchors: Compared with ordinary external resin anchors, there is no need to blow resin capsule, so as the construction efficiency is greatly improved.
