The present invention relates to a method of constructing a rockfall prevention structure using wiring, and more particularly, by inducing a rockfall prevention structure to be installed quickly and safely on a slope to minimize the construction period and suppress the occurrence of safety accidents. Rather, it relates to a method of constructing a rock-fall prevention structure using wiring that efficiently absorbs impact energy to suppress and block the intrusion of rocks from the road.

In general, when constructing a road including a mountainous area, an incision or slope is artificially formed due to cutting, etc. In such an incision or slope, the rock fragments are separated from the parent rock due to the relaxation of the discontinuity in the bedrock, and rockfall may occur. Not only that, but there is a risk of rock collapse in which the rock collapses on a large scale, so a fall prevention facility is installed.
