A stair-like revetment structure is formed by using sloping blocks. At the rear end of the block main body having an approximately rectangular and a rearwardly sloping flat step are provided rear engagement pods opening like a wedge at the rear of the main body and front engagement pods having an approximately same shape as the rear engagement pods extending adjacent a concave portion at the center bottom of the front of the main body, the concave portion being provided between the front and the rear engagement pods. This results in a low cost simplified sloping block structure. The thus structured sloping blocks are arranged next to each other on a sloping foundation, the front engagement pods of the sloping blocks of one layer being inserted into an engagement concave portion between the rear engagement pods of the adjacent block to successively cover the sloping foundation in a zig-zag and step-wise fashion, to thereby form a water passage with the concave portion of the upper layer sloping blocks and the engagement concave portion formed between the rear engagement portion of the sloping blocks of one layer below. The revetment structure can secure the safety of users since there are no exposed projections, holes, etc. on the stair-like steps.
