Product Advantage
1. Mortar can maintain uniformity throughout the entire length range.It can fully leverage the role of cement powder rolls
2. Beneficial for installation in fractured areas and areas prone to collapse holes
3. It has the characteristics of high anchoring force, immediate load-bearing capacity, no loss, and easy storage
Product Action Principle
The principle of hydraulic expansion anchor rod is to press the steel pipe into a flat shape, then enclose it into a circular shape.
When in use, the anchor rod is first inserted into the anchor hole, and then high-pressure water is injected into the flat circular steel pipe to force it to expand into a circular shape.
The anchoring force is supported by the friction force between the steel pipe expansion pressure and the hole wall squeezing.
Product Application
Hydraulic expansion anchor rods are suitable for soft rocks and fractured zones.
