Product Features & Applications

The hollow grouting anchor cable combines anchoring and grouting in a single system. Developed with advanced technology and adapted to local geological conditions, it enables integrated anchoring and grouting. It resolves common issues of conventional support, serves as a long‑term solution for moderate to good surrounding rock, and is also applicable to tunnels, slopes, and excavations—especially in challenging conditions like deep soft rock, fractured strata, and water ingress.

Product Advantages

  1. Dual anchoring structure combining end anchoring and full‑length grouting reduces the number of anchor cables required by more than 30% compared with ordinary anchor cables, directly lowering procurement costs for support materials.

  2. The built‑in hollow grouting core tube eliminates the need for additional pipe tying, and the tensioning step is omitted. The anchor cable can bear load immediately after installation, and grouting can be carried out in centralized operations.

  3. Resin consumption is reduced by over 70% compared with conventional anchor cables, significantly cutting material costs for anchoring agents.

  4. The integrated hollow grouting core tube eliminates the need for additional grouting pipe installation and the tensioning procedure. The installation time per anchor cable is shortened by 60%, greatly improving construction efficiency and reducing labor costs for underground operations.

  5. Anchoring and grouting can be completed simultaneously, eliminating the need for secondary grouting operations, further shortening the construction period and reducing the overall costs of equipment rental and labor.
