Benefits & Features
The design principle of a hydraulic expansion rock bolt is to use high-pressure water injected into the bolt body to cause it to expand. When water is injected, the internal expansion element expands and adheres tightly to the borehole wall, forming a stable anchoring structure. This accessory is an essential tool for installation and requires no grouting. It is suitable for fractured and weak rock formations and can also be used for temporary support, providing a fast and effective support structure.
