Hybrid draped net system can be regarded as a combination of rockfall mitigation system at the upper part, rockfall guidance system at the middle and rockfall accumulation segment at bottom. The rockfall mitigation system, which is set up like an open pocket by post, anchorage, ring nets, support ropes, is utilized to intercept and mitigate rockfalls coming from above and lead them to the guidance and collection part below. Different from slope stabilization system, the guidance system is not tightly covered on the slope but preset a certain space from the surface by propping up anchor rods in order to lead the rockfalls and debris to the accumulation area, it can also prevent the splashing and bouncing of falling rocks which threat the protected area. Convenient to clean and remove the intercepted spillages from coverage area, the accumulation segment prevents the risk of hazard eliminate in high place and secondary harm, compare to the normal rockfall mitigation system.
