Ecological slope protection structure and construction method thereof

The invention relates to an ecological slope protection structure and a construction method thereof, and belongs to the field of road subgrade engineering and bank protection engineering. The ecological slope protection structure comprises a banket structure and a slope protection surface layer, the banket structure is positioned at a toe of a side slope, the slope protection surface layer covers the surface of the side slope, the banket structure consists of wood pile banket arranged along the direction of a toe line of the side slope into a row, the slope protection surface layer consists of a reversed filter and manually set stone laid on the reversed filter, a slope protection forest and a turf which are arranged in an array manner are planted on the slope protection surface layer, the reversed filter consists of a coarse sand cushion layer on the side slope and a gravel layer on the coarse sand cushion layer, the thickness of the coarse sand cushion layer is not smaller than 10cm, and the thickness of th
