Layout and construction method of anti-erosion revetment structure of bent river channel of urban inland river

The invention discloses a layout and construction method of an anti-erosion revetment structure of a bent river channel of an urban inland river. The river channel is spatially divided into a sand retention and deposition carbon sink greening area (I), a water and soil conservation bank fixing and anti-erosion area (II) and a slow flow slope protection garden leisure embellishment area (III); the sand retention and deposition carbon sink greening area (I) is located at the convex bank of a river channel, hydraulic kinetic energy is weakened by planting filtering aquatic plants, hygrophyte shrubs and water-resistant arbors, and the effects of retention, energy buffering and deposition on upstream water flow are achieved. The water and soil conservation bank fixing anti-corrosion area (II) is located at a river channel concave bank opposite to the sand retention deposition carbon sequestration greening area (I), and slope protection anti-corrosion building blocks are arranged to resist hydraulic scouring and pl
