Rust-free anchor cable is a new type of non-metallic anchor cable recently developed by the Institute of Prospecting Technology. Through the study of domestic and foreign anchor cable body, pressure pad, external anchorage, ancillary components, tensioning device, the overall structure of the anchor cable and anchor cable construction process, as well as two rounds of field tests, the results show that the non-corrosive anchor cable, with its unique performance, anchored in a special anchoring environment, is more effective and reliable than the steel anchors, and therefore has a great potential for the market!
