PROBLEM TO BE SOLVED: To provide a protecting fence reinforcing structure with supporting columns stable against load on protecting faces and superior in constructing efficiency for improving the protecting function of a protecting fence. SOLUTION: The plurality of reinforcing supporting columns higher than a protecting fence body 1 are erected at intervals near the existing protecting fence body 1, and upper protecting faces 23 higher than the protecting faces 4 are provided between the reinforcing supporting columns 12. The upper protecting faces 23 each have a band body 21. The protecting function is improved by upwardly expanding the protecting faces 4 of the existing protecting fence body 1. Particularly, the band body 21 of the upper protecting face 23 has a large contact area with deposited snow, and so there is no need for shutting off the reinforcing supporting columns 12, 12 from each other with a metal gauge and the metal gauge are usable with great meshes, thus simplifying the construction of the protecting faces 23.
