The energy dissipation pool 20 is arranged on the beach and decreases in height in the direction close to the sea. The first drainage port 11 is arranged at the end of the energy dissipation pool 20 away from the sea. The energy dissipation pool 20 has an energy dissipation space to make the water discharged by the first drainage port 11 flow to the sea through the energy dissipation space after flowing into the energy dissipation space. The energy dissipation pool 20 is arranged between the pipe culvert 10 and the sea to play a transition role. On the one hand, it can reduce the impact and corrosion of the sea waves on the first drainage port 11 of the pipe culvert 10, avoid poor drainage, and protect the pipe culvert 10. On the other hand, it can introduce the water discharged by the first drainage port 11 into the sea in a horizontal manner. The heights of the first drainage port 11 and the energy dissipation pool 20 are higher than the sea level, so that the water discharged by the first drainage port 11 enters the sea in a overflow manner, ensuring the integrity of the beach and the ecological environment.

[0026] The energy dissipation pool 20 is arranged in a sunken form on the beach, the inner side of the end of the energy dissipation pool 20 away from the sea is provided with a stepped structure 30, the stepped structure 30 decreases in height towards the sea, the upper part of the stepped structure 30 is provided with a multi-layer block stone pavement, the top platform of the stepped structure 30 is used for beach shoulder sand supplement, and the elevation of the end of the energy dissipation pool 20 away from the sea is greater than 3 times the inner diameter of the pipe culvert 10.

[0027] The energy dissipation pool 20 is an irregular closed loop structure, the energy dissipation pool 20 is a closed loop structure composed of a first side 21 away from the sea, and sequentially connected second, third and fourth sides 22, 23 and 24, wherein the first side 21 is perpendicular to the plane of the pipe culvert 10, the third side 23 opposite to the first side 21 is an arc surface, the second and fourth sides 22 and 24 opposite to each other can be planes or arc surfaces, in addition, the second, third and fourth sides 22, 23 and 24 can form a smooth transition arc structure, which can better resist the impact of sea waves.

[0028] The inner sides of the second and fourth sides 22 and 24 of the energy dissipation pool 20 are respectively provided with slope structures 40, wherein the height of the slope structure 40 decreases in a stepped manner along the direction close to the center of the energy dissipation pool 20, and the height of the slope structure 40 decreases along the direction close to the sea, when the sea waves from the center of the third side 23 with the lowest height flow into the energy dissipation space of the energy dissipation pool 20, the slope structure 40 can gradually reduce the impact force of the sea waves, so that the overall structure of the energy dissipation pool 20 will not be damaged even when encountering strong wind and waves, and plays a good buffering effect.

[0029] According to an embodiment of the slope structure 40, the slope structure 40 is formed by three rows of block stones to form inner, middle and outer three layers of retaining walls, which gradually slope towards the inside of the energy dissipation pool 20 and the sea side, and the slope is more gentle than the energy dissipation pool 20, but the overall slope is about the beach slope, forming a water storage space surrounded by the block stone retaining wall, which can provide a certain recreation space for tourists.

[0030] The outer side of the end of the energy dissipation pool 20 close to the sea is provided with a gravel concrete structure, that is, the wave-impact side retaining wall of the energy dissipation pool 20 is provided with a gravel concrete structure, the retaining wall close to the sea of the energy dissipation pool 20 is slightly higher than the outer side of the beach surface elevation, and lower than the top elevation of the retaining wall away from the sea, the retaining wall on the outer side of the end of the energy dissipation pool 20 close to the sea serves as a natural wave dissipation platform, which can reduce the direct erosion of the first drain 11 by waves, and help to avoid poor drainage, the overall drainage pipe 50 culvert is used for overflow drainage, the beach remains relatively complete, and the landscape is better.

[0031] The bottom surface 25 of the energy dissipation space is protected by pebbles to prevent the ground of the energy dissipation space from being washed away by the drainage of the first drainage outlet 11. It is well connected with the beach. The bottom surface 25 of the energy dissipation space is lower than the sea level. The part of the energy dissipation pool 20 above the normal water level is made of pebble concrete to serve as a resting platform. The part of the energy dissipation pool 20 below the normal water level adopts a porous biomimetic design to provide a certain habitat for small marine life.

[0032] The height of the first drainage outlet 11 is higher than the height of the end of the energy dissipation pool 20 closest to the sea, to prevent backflow and ensure that the water discharged from the first drainage outlet 11 flows smoothly to the sea.

[0033] In addition, the present invention provides a drain pipe 50 at the end of the energy dissipation pool 20 that is close to the sea, that is, a drain pipe 50 is provided in the middle or bottom of the third side 23. In this way, even if the water level in the energy dissipation space is low and does not reach the lowest position of the third side 23, water can still be drained to the sea through the drain pipe 50, and the impact force of the waves on the third side 23 can be further reduced.
