In this embodiment, the slope body 17 has a structure of a first-level horizontal slope-a first-level inclined slope-a second-level horizontal slope-a second-level inclined slope, and the arrangement of the slope body 17 with a multi-level slope structure can achieve a better wave-proofing effect.

[0029] Among them, the slope of the secondary horizontal slope is i2, and the slope of the primary horizontal slope is i1;

[0032] At the same time, a block stone cushion layer 4 is laid at the top of the slope body 17, which is located on the side of the arc-shaped wave-breaking bank 6 away from the retaining wall structure. The block stone cushion layer 4 extends to the bottom of the slope body 17, and the block stone cushion layer 4 also extends outward to connect with a horizontal block stone cushion layer 2 19.

[0033] Wherein, the cushion layer and the arc-shaped wave-breaking bank 6 are both arranged at the top of the first-level horizontal slope.

[0034] A concrete retaining wall 3 is arranged at the junction of the block stone cushion layer 14 and the block stone cushion layer 2 19. The concrete retaining wall 3 is made of plain concrete. A torsion block 2 is laid at the top of the block stone cushion layer 2 19, which is located outside the concrete retaining wall 3.

The width of the support seat 21 gradually decreases from bottom to top, and the width of the base 20 is greater than the maximum width of the support seat 21. The structural setting of being wide at the bottom and narrow at the top increases the stability of the structure, which helps to prevent wave impact.

[0044] Specifically, see Figure 5 and Figure 6 The protective fence panel 5 includes a plurality of unit panels 30 spliced ​​in sequence, and each unit panel 30 is provided with a plurality of holes 29 in a rectangular groove structure from top to bottom. The setting of the protective fence panel 5 can effectively offset and reduce wave energy. At the same time, the holes 29 set on the protective fence panel 5 can also serve as a habitat for aquatic plants and animals, which can not only increase the diversity of aquatic populations, but also promote the reproduction and growth of marine organisms, and protect the stability and integrity of the marine ecosystem.
