Slope protection structure of mucky earthwork

The utility model provides a muddy earthwork slope protection structure, which relates to the technical field of slope protection, and comprises an inner slope sludge layer and an outer slope sludge layer, the inner slope sludge layer is positioned on the inner side of the slope protection, and the outer slope sludge layer is positioned on the outer side of the slope protection; the inner slope sludge layer is river slope sludge, and the outer slope sludge layer is excavated river bottom sludge; lime powder layers are laid on the tops of the inner slope sludge layer and the outer slope sludge layer; a stone layer is laid on the top of the lime powder layer. Slope sludge with low water content serves as the inner slope sludge layer, river bottom sludge with high water content is dug out to serve as the outer slope sludge layer, the outer slope sludge layer can be effectively prevented from collapsing, the lime powder layer effectively absorbs water in the sludge layers, and the inner slope sludge layer and the
