Finally, a protective fence 3 is set on one side of the highway 5, and the baffle 31 is stably supported by the support frame 32. A small amount of falling rocks pass through the first protective net 11 and the second protective net 22 and are blocked by the baffle 31, preventing the falling rocks from falling directly on the highway 5 and affecting the vehicles traveling on the highway 5. With the help of the active protective structure 1, the passive protective structure 2 and the protective fence 3, the defense effect against falling rocks on the slope 4 is greatly improved.

One end of an anchor rope 26 is fixed to the connecting ring 25, and the other end extends toward the slope 4, generating tension on the column 21. Finally, an anchor rod 27 is used to secure the other end of the anchor rope 26 to the slope 4. Another connecting ring 25 is fixedly mounted on the other side of the upper end of the column 21. One end of a corresponding anchor rope 26 is fixed to the connecting ring 25, and the other end extends toward the slope 4, generating tension on the column 21. Finally, an anchor rod 27 is used to secure the other end of the anchor rope 26 to the slope 4. The connecting ring 25 is prefabricated and mounted on the column 21.
