PURPOSE: A protection fence is provided to resist the energy of falling rock by dispersing the energy of falling rock depending on the size of the falling rock. CONSTITUTION: A protection fence comprises multiple posts and multiple protection nets(110). The posts are installed on a slope to be separated from each other. The protection nets are supported by the posts and are overlapped with each other. The size of each mesh(110A,110B,110C) of each protection net is uniform, and parts of the meshes of the protection nets adjacent to the slope have a bigger size than the other parts. |
