This is a facility that covers a cut surface at risk of falling rocks, using materials such as nets and buffer wire ropes with compression springs to deal with falling rocks from the rocky slopes of highways or general roads, thereby preventing falling rocks in advance and, in the event of falling rocks, guiding them from straying onto the road.

1. Improved rockfall stability
The wire rope, compression spring, and anchor are configured to absorb rockfall impact energy through the sliding function of the compression spring and the wire rope placed at the bottom, thereby preventing rockfall from moving toward the roadside, and stability is improved due to the improved rockfall compression force.
2. Application of dynamic shock absorption mechanism
The compression spring is compressed as a whole by the impact of the rockfall and then recovers to absorb the impact, and the wire rope placed at the bottom slides in the opposite direction to the compression spring to absorb the impact twice, thereby minimizing product deformation and damage.
3. Expected economic effects through reduced maintenance costs
Disassembly and assembly by section are possible, so only the damaged section can be maintained separately.
