A pillow bar 6 is arranged on the surface of the fixed column 5, and one side of the pillow bar 6 is in contact with the buffer layer 7. A protective plate 8 is arranged between two adjacent retaining seats 4 and on the surface of the pillow bar 6, and one side of the protective plate 8 is in contact with the buffer layer 7. When the protective plate 8 is impacted by water waves, the buffer layer 7 is squeezed, and the pillow bar 6 is squeezed at the same time. Since the buffer layer 7 is filled with crushed stone, the crushed stone particles are relatively large and the porosity is high, it can resist a certain deformation, thereby reducing the impact force on the dam.
[0022] The protective plate 8 includes a plate body 81, a curved plate 82 is arranged on one side of the plate body 81, and a mounting plate 83 is arranged on one side of the curved plate 82.

The mounting plate 83 is arranged parallel to the plate body 81, and the distance from the surface of the mounting plate 83 to the top of the mounting plate 83 is equal to the thickness of the plate body 81. During installation, the plate body 81 of another protective plate 8 is installed on the mounting plate 83. Since the gap is reduced, the loss of soil is reduced. When water waves impact the plate body 81, the movement direction of the water waves is changed due to the action of the curved plate 82, thereby reducing the scouring of the slope 3 of the dam slope protection and reducing soil loss.
[0023] An anti-sliding block 86 is provided on the back of the plate body 81, and a plurality of anti-sliding blocks 86 are provided to improve the stability of the protective plate 8.

The retaining wall 10 and the planting trough 11 extend along the length direction of the dam body 2. Green plants and other plants can be planted in the planting trough 11 to optimize the dam scenery. A drainage pipe 12 is provided at the bottom of the planting trough 11. The drainage pipe 12 extends along the dam slope protection slope 3 to the top of the riverbed 1. Drainage can be achieved through the drainage pipe 12 when it rains.
