PROBLEM TO BE SOLVED: To make a simplified impression of a slope surface by visually emphasizing one beam group extending from a high location to a low location of the slope surface, out of intersecting beams forming slope protective works. SOLUTION: The slope protective works are formed like a lattice, constituted of a plurality of longitudinal beams 2 extending from the high location to the low location of the slope surface 1, and arranged in parallel with each other, and a plurality of transverse beams 3 extending in a direction that intersects the longitudinal beams 2, and arranged in parallel with each other, and anchored to the slope surface 1 by anchor members 4. Each longitudinal beam 2 is constituted of a plurality of thin beams 2a arranged in parallel with each other so as to be spaced an interval away from each other, and the thin beams 2a are formed of cast-in-place concrete. On the other hand, each transverse beam 2 is formed of a PCa member and arranged so as to be lower in height than the longitudinal beams 2. Further, each anchor member 4 is arranged at a location between the thin beams 2a and corresponding to an intersection between the longitudinal beam 2 and the transverse beam 3.
