Geotechnical anchorage technology produced in the early 20th century England, it takes advantage of the high tensile strength and elongation of rock bolt, calls and improves the rock-soil body's own strength and self-stability, fully taps the potential of rock and soil , effectively saved the cost of the project and contributed to construction safety, thus becoming one of the most economical and effective way to improve the geotechnical stability and solve the complex and difficult geotechnical problems. The technology has been widely used in the actual project. However, the service life of the rock bolt embedded in the rock formation more depends on the ability to resist corrosion.
After many years of field research, Sinorock company found that corrosion of the rock bolts and accessories mainly comes from electrolytic phenomena. Rock bolt corrosion should also react in the cathode and anode. Causing this reaction force is the potential difference between the polar region. In view of the above reasons, the double/multiple corrosion rock bolt that sinorock research team independently research and develop effectively solved this problem, making sinorock's rock bolt products can be applied to a large number of complex environments that have high protection against corrosion requirements, such as undersea tunnel, hydropower and other occasions. Sinorock has become the first brand of corrosion-resistant rock bolt in Asia!
