It has a breaking effect on the waves. The waves hit the gravel layer 12 and are broken into small waves from the whole, and consume the energy of the waves to reduce the possibility of reflected waves. The broken waves pass through the first wave. The sponge layer 13 is absorbed and buffered by the first sponge layer 13, and further consumes the energy of the waves; the wave-absorbing pipe 14 is fixed on the support frame 11, and the wave-absorbing pipe 14 is located under the first sponge layer 13, and a plurality of wave-absorbing pipes 14 Arranged side by side, the wave absorbing pipe 14 has a water inlet and a water outlet, the water inlet abuts the first sponge layer 13, the water outlet is vertically downward, and most of the water flow from the first sponge layer 13 directly enters the wave absorbing through the water inlet.
