Geotechnical anchoring is an important branch of geotechnical engineering. There are several advantages while using geotechnical anchoring technology fully: increase rock strength, effectively improve rock stress, significantly save engineering materials, and apparently improve engineering safety. Geotechnical anchoring technology has become one of the most economical and effective methods to improve engineering stability.

But meanwhile, the long-term working performance of the anchor bolt has also troubled geotechnical engineers. Especially in the past 20 years, China geotechnical anchoring technology has been widely used in civil engineering, hydropower stations, railways, and infrastructure construction, and its usage and scale are among the highest in the world. Therefore, studying the long-term working performance of the anchor bolt is of great significance to the design, construction, anti-corrosion of permanent geotechnical anchorage engineering, and the formulation of geotechnical anchorage engineering standards.

To solve the problem of long-term working performance of the anchor bolt, Sinorock has produced duplex anti-corrosion anchor bolts after years of research. The product combines two measures which are hot-dip galvanizing and epoxy coating. Hot-dip galvanizing involves dipping the article with a chemically clean surface into a bath of molten zinc, which reacts with the iron and forms a coating and to prevent rusting; Epoxy coating doesn’t react with acid, and alkali. It has good chemical stability. Meanwhile, an electrical insulation layer can prevent the steel bars from contacting the external current, which can make the antiseptic effect good. The combination of double coatings achieves the effect of permanent anchor support.

Sinorock is an experienced manufacturer of anchoring products with over 10 years’ production. Sinorock products have been exported to more than 40 countries on 6 continents. Sinorock has professional product research and development team which makes customized service available. According to customers’ demands, Sinorock engineers provide system solutions based on different engineering and geology, making project construction safer and more efficient.
