Sinorock® rock bolts are passive ties with construction

Since self drilling rock bolt is mainly used in the fault fracture zone advanced support construction, under the complex geological conditions instead of ordinary catheter, overcoming the problems such as hole collapse, unable to plug rod, grouting is not full,ect. which played a supporting role in advance, ensuring the overall stability of the surrounding rock, and the safety of construction personnel and tunnel, with good application value.

Sinorock® rock bolts are passive ties; typically classified as lightly loaded, short installations. The Sinorock® Rock Bolt System provides a practical rock bolt that is quick and easy to install through fractured or broken ground. The system is available with a range of harder drill bits (Tungsten Carbide: button or chisel) for efficient drilling in stronger material.

Air or water flush percussive drilling is normally employed for installation, followed by subsequent grout injection through the bore of the bar. Injected grout provides the bond for the Sinorock® rock bolts and also helps to consolidate fractured ground. For mining applications, the Sinorock® rock bolt system is used as self-drilling rock bolts in areas of high stress at pillars, crossheads or abutments. Other applications include the use of the self-drilling bar as an injection conduit for resin, grout or waterproofing agents.
