Description

Technical Field

[0001] This utility model relates to the field of wave protection and sand fixation technology, and in particular to a coastal ecological protection wave protection and sand fixation facility. Background Technology

[0002] As the boundary between land and sea, the coastal zone plays a vital role in ecological environment, economic development, and disaster prevention and mitigation. However, affected by factors such as storm surges, wave erosion, and sea-level rise, many coastal areas face problems such as shoreline retreat, beach loss, and ecological degradation, threatening the stability of coastal infrastructure and ecosystems. Traditional coastal protection facilities, such as concrete breakwaters and riprap revetments, can effectively resist wave erosion.

[0003] Traditional coastal protection facilities, such as concrete breakwaters and riprap revetments, can effectively resist wave erosion, but they often have drawbacks such as damaging the natural ecosystem, affecting sediment transport, and reducing the self-recovery capacity of the coast. Therefore, we propose this utility model. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a coastal ecological protection, wave-breaking, and sand-fixing facility.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A coastal ecological protection and wave-breaking sand-fixing facility includes a dike, one side of which has an extended slope, and a protective structure for wave-breaking and sand-fixing is provided on one side of the dike. The protective structure includes several permeable holes opened on one side of the dike, and two mesh screens are fixed inside the permeable holes. The two mesh screens are spaced apart, and the space between the two mesh screens is filled with gravel. The dike is made of reinforced concrete, and the aperture of the mesh screens is smaller than the diameter of the gravel.

[0007] As a further embodiment of this utility model, a number of artificial reefs are fixed on the top surface of the extended slope, and multiple through holes are opened on the outer circular wall of the artificial reefs. A number of ecological bricks are fixed between the extended slope and the dam.

[0008] As a further embodiment of this utility model, a fixed grid is fixed on the other side of the dam, and a matrix layer is fixed on the ground of the fixed grid. The matrix layer is filled with artificial matrix and salt-tolerant plant seeds.

[0009] As a further embodiment of this utility model, the ground of the extended slope is fixed with a number of fixing blocks, the bottom of the fixing blocks being pointed, and the fixing blocks being evenly distributed along the length of the extended slope.

[0010] As a further embodiment of this utility model, fixing plates are fixed on both sides of the dam, and the fixing plates are made of concrete.

[0011] As a further embodiment of this utility model, the top surface of the dam is provided with a number of anti-slip grooves, which are evenly distributed along the length of the dam.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This wave-breaking and sand-fixing facility, through the design of its protective structure, weakens the flow velocity of waves after they enter the gravel-filled area through the permeable holes, thereby reducing the impact on the dike and the erosion of the coast by reflected waves. At the same time, the gravel can intercept sediment and promote deposition, achieving the effect of wave-breaking and sand-fixing. The installation of artificial reefs and ecological bricks not only provides habitats for marine life and promotes ecological restoration, but also further enhances the stability of sediments and reduces the wave energy impacting the dike. Overall, this facility integrates multiple functions such as wave breaking, sand fixation, and ecological restoration, improving the durability of the dike and the coastal protection capacity, and is suitable for coastal areas prone to erosion.

[0022] Reference Figures 1-4 A coastal ecological protection and wave-breaking sand-fixing facility includes a dike 1, an extension slope 2 on one side of the dike 1, and a protective structure for wave-breaking and sand-fixing on one side of the dike 1. The protective structure includes several permeable holes 201 opened on one side of the dike 1. Two mesh screens 202 are fixed inside the permeable holes 201. The two mesh screens 202 are spaced apart, and the space between the two mesh screens 202 is filled with gravel 203. The dike 1 is made of reinforced concrete, and the aperture of the mesh screens 202 is smaller than the diameter of the gravel 203.

[0023] In this embodiment, several artificial reefs 204 are fixed on the top surface of the extension slope 2. Multiple through holes 205 are opened on the outer circular wall of the artificial reefs 204. Several ecological bricks 206 are fixed between the extension slope 2 and the dike 1. The dike 1 is located in the intertidal zone, and the extension slope 2 and the ecological bricks 206 are both located near the sea. Through the setting of the protective structure, after the waves enter the area filled with gravel 203 through the permeable holes 201, their flow velocity is weakened, thereby reducing the impact on the dike and the erosion of the coast by reflected waves. At the same time, the gravel 203 can intercept sediment and promote deposition, achieving the effect of wave protection and sand fixation. The setting of artificial reefs 204 and ecological bricks 206 not only provides a habitat for marine life and promotes ecological restoration, but also further enhances the stability of sediments and reduces the wave energy of waves impacting the dike. Overall, the facility integrates multiple functions such as wave protection, sand fixation, and ecological restoration, improves the durability of the dike 1 and the coastal protection capability, and is suitable for coastal areas that are prone to erosion.

[0024] In this embodiment, a fixed grid 3 is fixed on the other side of the dike 1. A matrix layer 301 is fixed to the ground of the fixed grid 3. The matrix layer 301 is filled with artificial matrix 302 and salt-tolerant plant seeds. The fixed grid 3 is located in the beach or tidal flat area. The fixed grid 3 is made of biodegradable material to reduce environmental pollution. The matrix layer 301 is made of natural fibers such as cotton and hemp, with a loose upper layer and a dense lower layer. When waves enter the beach through the permeable holes 201 on one side of the dike 1, the fixed grid 3 can effectively fix the sand and soil, reduce sand loss, and prevent seawater from further eroding the beach. At the same time, the matrix layer 302... 1. By providing a suitable growth environment, it promotes the germination and growth of plant seeds and enhances soil stability. The loose upper structure of the substrate layer 301 allows water to easily penetrate, which is beneficial to the growth of plant roots, while the dense lower structure can prevent water loss and improve the soil's resistance to erosion. The biodegradable material of the fixed grid 3 will gradually degrade after long-term use and naturally integrate with the environment, avoiding negative impacts on the coastal ecology. Through this design, the dike 1 not only plays a role in wave protection and sand fixation, but also promotes ecological restoration and natural plant reproduction, enhancing the ecological function and sustainability of the beach or tidal flat area.

[0025] In this embodiment, several fixing blocks 4 are fixed to the ground of the extended slope 2. The bottom of the fixing blocks 4 is a pointed end. The fixing blocks 4 are evenly distributed along the length of the extended slope 2. The extended slope 2 is made of a high-strength material with good corrosion resistance. The pointed ends of the fixing blocks 4 can penetrate into the soil or sand surface to play an anchoring role. This makes the extended slope 2 less prone to displacement under the action of waves or tides, thereby stabilizing the slope and improving its erosion resistance.

[0026] In this embodiment, fixing plates 5 are fixed on both sides of the dam 1. The fixing plates 5 are made of concrete and can be buried underground to enhance the stability and impact resistance of the dam 1.

[0027] In this embodiment, a number of anti-slip grooves 6 are provided on the top surface of the dam 1. The anti-slip grooves 6 are evenly distributed along the length of the dam 1. The anti-slip effect of the top surface of the dam 1 is enhanced by the anti-slip grooves 6, thereby improving the safety of maintenance personnel.

[0028] Working Principle: During use, through the protective structure, waves are weakened after entering the gravel 203 filling area through the permeable holes 201, thus reducing the impact on the dike and the erosion of the coast by reflected waves. Simultaneously, the gravel 203 intercepts sediment, promoting deposition and achieving wave protection and sand fixation. The artificial reefs 204 and ecological bricks 206 not only provide habitats for marine life and promote ecological restoration but also further enhance the stability of sediments and reduce wave energy impacting the dike. Overall, this facility integrates multiple functions such as wave protection, sand fixation, and ecological restoration, improving the durability of the dike 1 and its coastal protection capabilities. It is suitable for erosion-prone coastal areas. When waves enter the beach through the permeable holes 201 on one side of the dike 1, the fixed grid 3 effectively fixes the sand, reducing sand loss and preventing further seawater erosion of the beach. Meanwhile, the matrix layer 301 provides suitable... The growing environment promotes plant seed germination and growth, enhances soil stability, and the loose upper structure of the substrate layer 301 allows water to easily penetrate, which is beneficial to plant root growth, while the dense lower structure prevents water loss and improves the soil's resistance to erosion. The biodegradable material of the fixing grid 3 will gradually degrade after long-term use, naturally integrating with the environment and avoiding negative impacts on the coastal ecology. Through this design, the dike 1 not only plays a role in wave protection and sand fixation, but also promotes ecological restoration and natural plant reproduction. The pointed ends of the fixing blocks 4 can penetrate deep into the soil or sand surface to act as anchors, making the extended slope 2 less prone to displacement under the action of waves or tides, thus stabilizing the slope and improving its resistance to erosion. The fixing plates 5 can be buried underground to enhance the stability and impact resistance of the dike 1. Several anti-slip grooves 6 enhance the anti-slip effect on the top surface of the dike 1 and improve the safety of maintenance personnel.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
