The application of glass fiber resin anchor rods in global engineering

The products of Hebei Chiyang New Materials Co., Ltd. have been successfully applied in various fields such as coal mine tunnels, semi-coal rock tunnels, slope support, rock surface anchoring, subways, tunnels, bridges, roads, hydropower stations, ports, coastal reclamation, and construction pit foundations. They have solved the technical problems of superior corrosion resistance and long service life compared to ordinary steel in these fields. Due to the machinability of FRP materials, it has effectively solved the problem of exceeding the red line in building pit support and subway construction (industry standard: Shield Cutting Concrete Reinforcement Technical Specification). 

Hebei Chiyang New Materials Co., Ltd. produces various specifications of full-thread glass fiber solid anchor rods, hollow grouting anchor rods, self-drilling anchor rods and building glass fiber strands. The annual output exceeds 15 million meters. The products are mainly exported to European markets such as Germany and Austria, as well as developed countries and regions in North America, Japan, Australia, Russia, Southeast Asia, Central and South East Africa, and South America. Currently, the products have been sold to mining areas in Inner Mongolia, Xinjiang, Northeast China, Shanxi, Shandong, Henan, Anhui, etc. and have long-term and close cooperation with companies such as Shenhua Group and Yitai Group. The products are widely used in subway, river-crossing tunnels, and foundation pit projects in Beijing, Nanjing, Guangzhou, Shenzhen, Suzhou, Hunan, Sichuan, Shanghai, etc. The product performance is excellent, the quality is stable, and the performance has been tested by many national-level testing centers, and the performance is superior to the current domestic standards and norms. 

Details of FRP anchor rod products: 

Glass fiber reinforced anchor rods are a new type of composite material product that replaces metal anchor rods. They are made with glass fibers as the reinforcing material and polyester resin as the base material. Through the traction of a special pultrusion machine and pre-forming molds, they are cured under high temperature and high pressure to become fully threaded glass fiber reinforced plastic rods. These rods are combined with resin anchor agents, trays, and nuts to form glass fiber reinforced anchor rods. They are mainly used for tunnel support, rock face anchoring, slope anchoring, support of coal mine tunnels, semi-coal rock tunnels, and various underground engineering support, as well as deep foundation pit anchoring. The product features include high strength, with tensile strength superior to that of ordinary steel, even reaching more than twice that of steel anchor rods of the same specification. They are lightweight, being one quarter of the weight of steel anchor rods of the same specification. They are easy to cut without damaging the cutting machine or coal mining machine. They have a safe surface, are non-static electricity, flame retardant, do not produce sparks, are non-conductive and non-heat-conductive. They are highly durable and resistant to corrosion, with good durability. The bonding strength is strong, combining well with the anchor agent and concrete. The thermal expansion coefficient is close to that of cement. It is a fully glass fiber reinforced anchor rod for mine shafts, highways, railway tunnels and slope support, consisting of glass fiber reinforced nuts, trays and anchor rods. One end of the glass fiber reinforced anchor rod is equipped with a glass fiber reinforced nut and tray. The glass fiber reinforced nut limits the axial movement of the glass fiber reinforced tray. The other end of the glass fiber reinforced anchor rod has an inclined thread. The characteristic is that the glass fiber reinforced anchor rod is sleeved with the glass fiber reinforced nut through arc-shaped toothed threads. The end of the glass fiber reinforced nut close to the glass fiber reinforced tray is extended and contracted to form a neck.
