[0003] Generally, rockfall prevention facilities are installed in areas where bedrock is formed on cut slopes and there is a risk of rockfalls to prevent industrial accidents and traffic accidents.

[0005] For example, there is a pocket type of facility for preventing rockfalls in which a net is attached to a rock wall, wires are crossed in longitudinal and transverse directions, and then anchor bolts are used to secure the wires at the point where the longitudinal and transverse ropes intersect to prevent rockfalls.

[0007] To explain the pocket-type rockfall prevention facility described above in more detail, the rockfall prevention facility comprises a net (e.g., a PVC-coated net) covering a slope or rock wall, wires crossing in longitudinal and transverse directions to ensure the net adheres closely to the slope, and clamps for connecting the intersection points of the wires.

[0009] However, according to the conventional technology, a rockfall prevention net structure can prevent rockfalls by installing wires in the longitudinal and transverse directions on the upper part of the net to press the net toward the slope. However, since the wires do not maintain tension taut and are merely placed on the upper part of the net, the net is not supported toward the slope and lifts away from the slope, causing a rockfall phenomenon.

[0011] In addition, there was a problem where the load from falling rocks was transferred to the wire, causing it to become unstable instantly because it could not withstand the load.

[0013] Accordingly, a method was developed to fix a clamp where the wires cross to the ground using an anchor bolt, as described in Korean Registered Patent No. 10-1530081, "Wire cushioning device having a cushioning slot and method for constructing a rockfall prevention facility using the same," but there was a problem that the structure was complex and required a lot of time for installation.
