[0035] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0036] like Figure 1-3As shown, an ecological protection structure for a deep-water dike includes a main revetment structure, which, from bottom to top, consists of a riprap foundation 1, a caisson 2, and a reinforced concrete breast wall 3. The riprap foundation 1 serves as a reference point, with one side forming the intertidal zone in front of the dike and the opposite side forming the rear zone. The caisson 2 is a reinforced concrete structure with two compartments, each measuring a standard 4.2m × 4.2m. A cast-in-place reinforced concrete breast wall, employing an inverted "Z" shaped structure, is installed on top of the caisson 2. Combined with... Figure 1 As shown, the riprap foundation 1 includes a horizontal section, and two rows of caissons 2 are fixedly installed in the horizontal section, with the vertical height of the two rows of caissons 2 increasing from the intertidal zone in front of the dike to the area behind the dike.

[0037] The reinforced concrete breast wall 3, which is fixedly installed on top of the two rows of caissons 2, has an arc-shaped side facing the intertidal zone in front of the dike. This arc-shaped side is used to guide the rising tide waves to avoid the waves directly impacting the reinforced concrete breast wall 3.

[0038] The aforementioned boulders bed 1 uses 10-100kg of fresh quarry stone with a mud content of less than 5% and a softening coefficient greater than 0.75.

[0039] Furthermore, in combination Figure 1 As shown, the water-facing slope protection structure, located in the intertidal zone in front of the dike, consists of a large stone masonry slope protection 4 and a twisted block 5 fixedly installed from bottom to top on a riprap foundation 1. The large stone masonry slope protection 4 is divided into two layers: the first layer consists of large stones weighing 100-200 kg with a thickness of less than 1.0 m, and the second layer consists of large stones weighing 1-1.5 t each with a thickness of less than 2.0 m. The side of the twisted block 5 facing the intertidal zone in front of the dike is vertical, while the side of the large stone masonry slope protection 4 facing the intertidal zone in front of the dike is inclined. The large stone masonry slope protection 4 is structurally divided into a first straight section, an inclined section, and a second straight section. The two ends of the inclined section are connected to the first and second straight sections, respectively. The first straight section is located at a high position in the vertical direction and is connected to the caisson 2.

[0040] Secondly, combining Figure 1 As shown, on the seaward side of the structure, that is, in the area behind the breakwater, a riprap prism 7 and a filter layer 6 are fixedly installed on one side of the riprap foundation 1. The filter layer 6 here comprises 400g / m³... 2 The geotextile filter layer, crushed stone cushion layer, and two-piece stone, with a particle size of 22cm-18cm, are used.

[0041] Furthermore, the above embodiments also include a wave-dissipating ecological zone in front of the dike, which consists of multiple wave-dissipating block box structures 8 installed in a linear array on the intertidal zone in front of the dike.

[0042] The wave-dissipating block box structure 8 includes a wave-dissipating stepped box integral casting structure composed of three stepped structures, so that the eight sides of the wave-dissipating block box structure 8 are the front wall 815, two oppositely distributed side walls 818, the second rear wall 821, the bottom wall 820, and the top of the steps.

[0043] The top of the staircase has no fewer than three steps, and each step is fixedly provided with an upper step 811, a middle step 812 and a lower step 813 from top to bottom.

[0044] As mentioned above, wave-damping slits 819 are linearly arrayed along the vertical direction on the front wall 815, the middle wall 816, and the first rear wall 817. The wave-damping block box structure 8 is a hollow structure, and the wave-damping slits 819 are connected to the hollow structure.

[0045] The upper step 811, the middle step 812, and the lower step 813 are all provided with wave-dissipating holes 814 arranged in a horizontal linear array. The wave-dissipating joints 819 and wave-dissipating holes 814 on the seaward side promote water circulation and dissipate weak waves, thereby causing waves to oscillate and dissipate within the block, ensuring a stable and good marine water quality environment for the dike.

[0046] The opening ratio of the aforementioned wave-damping hole 814 is 15% to 20%.

[0047] It should be noted that the wave-dissipating block box structure 8 can be cast as a whole during construction, using prefabricated construction, and is made of eco-friendly concrete. Furthermore, during the casting process, to increase the overall stability of the structure, the thicknesses of the bottom wall 820 and side walls 818 are calculated and determined based on the wind and wave conditions of the project area.

[0048] Secondly, the top of the step includes at least two middle walls 816 and a first rear wall 817 parallel to the front wall 815;

[0049] The upper step 811 and the first rear wall 817 are on the same plane;

[0050] The central step 812 and the central wall 816 are on the same plane;

[0051] The lower step 813 and the front wall 815 are on the same plane.

[0052] In summary, the wave-dissipating block box structure 8 is generally set in the intertidal zone in front of the dike, and the upper step 811 is generally set near the average tide level. It, together with the lower step 813 and the wave-breaking plate, can break up the incident waves and generate a large amount of energy dissipation. Secondly, the groove structure at the rear of the structure can provide habitat and shelter for marine life. The integral cast-in-place structure of the wave-dissipating block box structure 8 can ensure the stability of the structure. The wave-dissipating joints 819 on the front and rear walls can ensure the free flow of water while dissipating weak currents and causing waves to oscillate and dissipate inside the block, ensuring a stable and good marine water quality environment for the dike.

[0053] The aforementioned fixing methods are either concrete construction fixing or conventional fixing methods for prefabricated buildings, without going into excessive detail.

[0054] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
