Produkto aprašymas
Jining Dongyanbo Mining Equipment Co., Ltd.'s High Strength Hollow Grouting Anchors utilize high-strength, low-relaxation special steel strands, processed through a rigorous heat treatment process. Their overall tensile strength and yield strength far exceed those of ordinary grouting anchors, making them specifically designed for high-risk support scenarios such as deep mines, high-stress roadways, extremely fractured surrounding rock, and tunnel fault fracture zones. The product adopts a hollow integrated structure, ensuring unobstructed grouting channels and controllable grouting pressure. The grout can fully penetrate deep into the rock fissures, firmly cementing the fractured surrounding rock to form a high-strength load-bearing arch. Combined with the anchor cable's own high tensile strength, it achieves active reinforcement and powerful support, effectively resisting risks such as large deformation, collapse, and rock bursts in the surrounding rock. The steel strands are corrosion-resistant, fatigue-resistant, and possess excellent toughness. They are not easily broken or rusted even under long-term use in high-stress, humid environments. The product comes with complete locking and tray components, ensuring a tight fit, even stress distribution, and secure installation. It meets the high-strength, long-life support requirements under harsh working conditions, making it the preferred product for high-risk surrounding rock support.
