The hollow grouting anchor cable consist of hollow body structure and expansion shell anchor head, enabling immediate pre-tensioning upon installation, with a pre-tension force exceeding 150 kN. Grouting is performed through the hollow section inside, simple construction and significantly improving roadway support effectiveness and efficiency.

Our hollow grouting anchor cable primarily used for supporting mine shafts and large-section chambers in non-metallic mines, especially under complex and difficult conditions such as weak rock strata, fractured zones, and geological structural belts. It can also be applied to reinforce and strengthen rock and soil engineering projects like tunnels and slopes, suitable for hard or extremely hard rock conditions.

They're also used for the support or reinforcement of the tunnels in areas with water seepage in mines. When using resin anchor agents fails to install properly, in low anchoring force situation, or there is a large amount of water seepage from the drill holes, this product can be used. Firstly, use the expansion-type mechanical to anchor the end, then grout into the drill holes through the hollow anchor cable to achieve the functions of water blocking, anchoring and reinforcement.
