Reverse pre-stressed anchor cable reinforcement structure
The invention relates to the technical field of dangerous rock anchoring, and provides a reverse pre-stressed anchor cable reinforcement structure for reinforcing a dangerous rock; a stable rock body is arranged at the back side of the dangerous rock; the height of the stable rock body is lower than the top of the dangerous rock; a pre-stressed anchor cable comprises a free section, an anchor head and an anchorage section, wherein the free section penetrates into the stable rock body; the anchorage section is positioned in the dangerous rock; and the anchor head is positioned in the stable rock body. Compared with the prior art, in the reinforcement structure provided by the invention, the anchor head is positioned in the stable rock body, and the anchorage section is positioned in the dangerous rock to form a reverse anchorage mode of a pre-stressed anchor cable, so that the construction can be directly performed at the back side of the stable rock body in the process of anchoring the dangerous rock, the building of a scaffold is not required to be performed on the frontal surface of the dangerous rock, the problems of high cost and high risk caused by building the scaffold are prevented, and the problem of threatening the life and property safety caused by instability of the dangerous rock in the reinforcement process is prevented.
