Semicircular ecological cofferdam structure

Abstract

The utility model provides a semicircular ecological cofferdam structure. By means of the semicircular structural design, the overall stability is improved, and multiple ecological functions are achieved by filling the oyster shell gravel layer inside. The semi-circular structure is beneficial to dispersing and guiding wave energy, and compared with a vertical or angular structure, the semi-circular structure can reduce wave reflection and reduce impact of hydrodynamic force on the cofferdam and surrounding mud flat, so that erosion is effectively slowed down. Oyster shells not only enhance the structural stability, but also can further reduce wave impact, provide a buffering effect and reduce erosion to mangrove forests and surrounding mud flats. Besides, the oyster shells have natural water quality purification capacity and can adsorb suspended particles and pollutants in water and improve the ecological environment, so that resource utilization of the waste oyster shells is realized while the mangrove forest protection effect is improved, and a sustainable solution is provided for coastal ecological restoration.

Description

Technical Field

[0001] This utility model relates to the field of ecological cofferdams, and in particular to a semi-circular ecological cofferdam structure. Background Technology

[0002] Mangroves, as unique wetland ecosystems in coastal zones, play vital ecological roles, including wind and wave protection, carbon sequestration and storage, water purification, and maintaining biodiversity. However, under the influence of coastal development, aquaculture activities, and natural erosion, mangrove ecosystems often face problems such as habitat fragmentation, shoreline erosion, and ecological degradation. Traditional dike technologies for restoring mangrove wetlands or constructing artificial mangrove habitats often employ hard materials such as concrete and boulders. While these materials can quickly stabilize the shoreline, they cannot clean the water and are insufficient to reduce the impact of hydrodynamic forces on the dike and surrounding mudflats, thus failing to effectively mitigate erosion. Utility Model Content

[0004] To address the aforementioned problems in the prior art, this utility model provides a semi-circular ecological cofferdam structure.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0007] A semi-circular ecological cofferdam structure includes a cofferdam body and a cofferdam end cap. The cofferdam body is a hollow cavity with an opening at one end, and the cavity of the cofferdam body is filled with permeable material. The cofferdam end cap is installed at the opening of the cofferdam body.

[0008] Preferably, the main body of the cofferdam has a semi-cylindrical structure, and the end caps of the cofferdam are semi-circular.

[0009] Preferably, the main body of the cofferdam has a truncated quadrangular structure, and the cofferdam end cap is installed on the top of the main body of the cofferdam.

[0010] Preferably, the main body of the cofferdam and the surface of the cofferdam end cap are evenly distributed with perforations.

[0011] Preferably, the end cap of the cofferdam is fixed to the main body of the cofferdam by bolts.

[0012] Preferably, the permeable material is oyster.

[0013] (III) Beneficial Effects

[0014] The beneficial effects of this utility model are as follows: This application utilizes a semi-circular structural design to improve overall stability and achieves multiple ecological functions by filling the interior with a layer of oyster shell gravel. The semi-circular structure helps to disperse and guide wave energy, reducing wave reflection compared to upright or angular structures, thus reducing the impact of hydrodynamics on the cofferdam and surrounding mudflats, and effectively mitigating erosion. The oyster shells not only enhance structural stability but also further reduce wave impact, providing a buffer and reducing erosion of mangroves and surrounding mudflats. Furthermore, oyster shells have a natural water purification capacity, adsorbing suspended particles and pollutants in the water, improving the ecological environment. Therefore, this application, while enhancing mangrove protection, also achieves the resource utilization of discarded oyster shells, providing a sustainable solution for coastal ecological restoration.

[0023] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Please refer to Figures 1 to 3 The first embodiment of this utility model:

[0025] A semi-circular ecological cofferdam structure includes a cofferdam body 1 and a cofferdam end cap 2. The cofferdam body 1 is a hollow cavity with an opening at one end, and the cavity of the cofferdam body 1 is filled with a permeable material 3. The cofferdam end cap 2 is installed at the opening of the cofferdam body 1.

[0026] In this embodiment, the main body 1 of the cofferdam has a semi-cylindrical structure, and the end cap 2 of the cofferdam has a semi-circular shape.

[0027] In this embodiment, perforations are evenly distributed on the surfaces of the main body 1 of the cofferdam and the end cap 2 of the cofferdam.

[0028] In this embodiment, the cofferdam end cap 2 is fixed to the cofferdam body 1 by bolts.

[0029] In this embodiment, the permeable material 3 is oyster.

[0030] This application utilizes a semi-circular structural design to enhance overall stability and achieves multiple ecological functions through internal filling with oyster shell gravel. The semi-circular structure helps disperse and guide wave energy, reducing wave reflection compared to upright or angular structures, thus mitigating the impact of hydrodynamic forces on the cofferdam and surrounding mudflats and effectively slowing erosion. The oyster shells not only enhance structural stability but also further reduce wave impact, providing a buffer and reducing erosion of mangroves and surrounding mudflats. Furthermore, oyster shells possess natural water purification capabilities, adsorbing suspended particles and pollutants in the water and improving the ecological environment. Therefore, this application not only enhances mangrove protection but also achieves the resource utilization of discarded oyster shells, providing a sustainable solution for coastal ecological restoration.

[0031] refer to Figure 4 In the second embodiment of this utility model, the main body 1 of the cofferdam is a truncated pyramidal structure, and the end cap 2 of the cofferdam is installed on the top of the main body 1. The trapezoidal side of the main body 1 can effectively disperse the lateral earth pressure and water flow impact force. The stepped drop slows down the water flow speed, promotes sediment deposition, accelerates the formation of mudflats, and provides a suitable habitat for wetland plants such as mangroves.

[0032] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
