Hollow Grouting Anchors

Hollow Grouting Anchors integrate anchoring and grouting functions. The central through-hole design allows for high-pressure grouting, with the grout diffusing and filling fissures in the surrounding rock to form a unified reinforcement ring. Suitable for complex geological conditions such as fractured roofs, loose rock strata, and tunnel faults, they offer strong anchoring force and excellent seepage prevention. Jining Dongyanbo Mining Equipment Co., Ltd. manufactures Hollow Grouting Anchors in both standard and high-strength models, with customizable lengths and bundle counts. Sufficient stock is available for both wholesale and retail, and comprehensive after-sales service is provided.
