Description

Technical Field

[0001] This invention relates to the field of marine engineering protection technology, specifically to an embedded seawall wave-breaking device. Background Technology

[0002] With the deepening of marine resource development and utilization, the construction of various offshore marine engineering structures (such as artificial islands, offshore wind power foundations, and drilling platform cofferdams) is increasing. These marine structures, located in the deep-sea environment, are exposed to the reciprocating action of high-energy waves and strong ocean currents for extended periods. Because waves undergo intense reflection and diffraction when encountering obstructing structures, the surrounding flow field is easily disrupted, leading to severe localized erosion of the structure's foundation. This continuous erosion of the foundation reduces the load-bearing capacity and stability of the marine structures, and may even cause structural suspension and capsizing, seriously threatening the safety of offshore operations.

[0003] In existing technologies, the protection of marine structure foundations typically employs passive defense methods such as seabed riprap, interlocking concrete blocks, or extended pile foundations. However, these technologies have significant drawbacks in practical applications. First, in deep water or high sea state environments, traditional seabed riprap protection is highly susceptible to rolling away or settling under strong waves and currents, leading to the failure of the protective layer. Furthermore, subsequent underwater re-placement is difficult and costly. If relying solely on increasing pile foundation length or enlarging the volume of concrete gravity retaining walls to withstand wind and waves, the workload and material costs will increase exponentially in deeper waters, with extremely long construction periods. Currently, there is a lack of an integrated device that can be directly attached to the marine engineering structure, effectively reducing wave impact energy and actively suppressing foundation erosion, without being limited by water depth. Summary of the Invention

[0004] To address the aforementioned issues, an embedded seawall wave-damping device is provided. Utilizing the geometric characteristics of its energy-dissipating units, it converts wave energy into internally canceling fluid motion, thereby achieving an active and efficient wave-damping effect and reducing the direct erosion of marine structures and foundations by waves. This device facilitates on-site construction, installation, and subsequent maintenance. Furthermore, the layout and arrangement of the energy-dissipating units can be flexibly adjusted according to the specific protection requirements of marine engineering projects, demonstrating excellent adaptability and practicality.

[0005] To address the problems of existing technologies, the present invention provides an embedded seawall wave-breaking device, comprising: at least one energy dissipation unit disposed on the wave-facing side of the seawall, the energy dissipation unit being constructed as a ring-shaped structure with a notch in the radial plane and an opening in the axial direction, the notch forming the wave-facing surface; and a fixing structure for embedding and fixing the energy dissipation unit in the seawall; wherein the sidewall surface of the energy dissipation unit is configured to impede waves entering through the notch until the energy of the waves is weakened.

[0006] Preferably, the fixing structure includes a fixing plate and a channel steel for embedding into the embankment body. The fixing plate is attached to and fixedly connected to the outer wall of the energy dissipation unit, and the side of the fixing plate away from the energy dissipation unit is fixedly connected to the channel steel.

[0007] Preferably, there are multiple energy dissipation units, which are arranged in an alternating or matrix-like uniform distribution along the extension direction of the dike.

[0008] Preferably, it also includes a drainage component for timely discharge of water that accumulates in the cavity of the energy dissipation unit and around the device after being impacted by ocean waves.

[0009] Preferably, the drainage component is a drainage pipe connecting adjacent energy dissipation units.

[0010] Preferably, the drainage component is a drainage hole opened on the wall of the energy dissipation unit.

[0011] Preferably, the energy dissipation unit is a steel structure.

[0012] Preferably, the energy dissipation unit is also provided with a sacrificial anode block.

[0013] Preferably, the notch angles of the multiple energy dissipation units can be adapted and adjusted according to the wave wavelength and wave height of the sea area where the dike is located, and the notch directions are all oriented towards the main propagation direction of the incident waves.

[0014] Preferably, the steel structure of the energy dissipation unit is made of a specially made tube with an outer diameter of 1000 mm and a wall thickness of 20 mm.

[0015] The advantages of this invention compared to the prior art are: 1. This invention utilizes the geometric characteristics of the energy dissipation unit to forcibly guide and break up incident waves, converting wave energy into internally canceling fluid motion. This not only weakens the direct impact of waves on the marine structure but, more importantly, disrupts the downflow formed by waves at the bottom of the structure, thereby effectively suppressing wave erosion and scouring of the foundation roots and solving the common problem of foundation instability in marine engineering.

[0016] 2. This invention employs an embedded fixing structure, directly anchoring the device to the sidewall of the marine structure. This installation method, which relies on the main structure, eliminates the dependence of the wave-breaking device's placement on the seabed depth. Whether in shallow or deep-sea operating areas, it can be quickly installed using standardized components, significantly reducing the construction cost and timeframe of offshore projects.

[0017] 3. This invention utilizes a dedicated drainage component to achieve rapid self-drainage of accumulated water by leveraging the pressure difference of the waves themselves, thus avoiding the retention and corrosion of high-salinity seawater within the energy dissipation unit cavity. Simultaneously, in conjunction with the placement of sacrificial anode blocks, a cathodic protection system conforming to offshore marine engineering standards is constructed, ensuring that the device can withstand harsh marine environmental corrosion throughout its entire lifespan and reducing the high frequency of maintenance at sea.

[0025] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1 to 6As shown: An embedded seawall wave-breaking device includes: at least one energy-dissipating unit 1, which is configured as a ring structure with a notch 11 on the radial surface and an opening in the axial direction, the notch 11 forming a wave-facing surface; a fixing structure 2 for embedding and fixing the energy-dissipating unit 1 in the seawall; wherein the sidewall of the energy-dissipating unit 1 is configured to impede waves entering through the notch 11 until the energy of the waves is weakened.

[0027] When this embedded seawall wave-damping device is put into operation, its energy dissipation unit 1 is firmly embedded in the wave-facing slope of the seawall through the fixing structure 2. When waves strike, the energy dissipation unit 1 directly bears the impact through its wave-facing surface with gap 11, and its unique curved surface shape begins to play a key role. Part of the wave energy is guided to the inner cavity of the energy dissipation unit 1 and reflected by the inner wall to form reflected waves; at the same time, another part of the wave diffracts along the outer wall of the structure. These reflected waves, diffracted waves, and subsequent incident waves intersect, collide, and interfere with each other. In this dynamic process, the kinetic energy of the waves is effectively consumed and weakened. In addition, the continuous curved surface of the energy dissipation unit can disperse the concentrated impact force of the waves, thereby avoiding damage to the device due to excessive local stress and improving the overall durability. The core of this device lies in utilizing the geometric characteristics of the annular structure with gap 11 to convert wave energy into mutually canceling fluid motion, thereby achieving an active and efficient wave dissipation purpose and reducing the direct erosion of the seawall by waves. The embedded fixing method tightly integrates the device with the shoreline as a whole, enhancing its stability and reliability against wave impacts, while also actively reinforcing the shoreline structure. The steel material ensures the necessary strength and durability of the main structure in harsh marine environments. This device not only facilitates on-site construction, installation, and subsequent maintenance, but also allows for flexible adjustment of the layout and arrangement of energy dissipation units 1 according to specific shoreline protection needs, demonstrating excellent adaptability and practicality.

[0028] It should be noted that the embankment described in this embodiment is a broad engineering concept. In addition to conventional coastal dikes, it mainly refers to offshore marine engineering structures, including but not limited to vertical or sloping revetments around artificial islands, scour protection sleeves for offshore wind power foundations, and caisson sidewalls for offshore drilling platforms.

[0029] like Figures 1 to 6 As shown: The fixed structure 2 includes a fixed plate 21 and a channel steel 22 for embedding into the embankment body. The fixed plate 21 is attached to the outer wall of the energy dissipation unit 1 and fixedly connected thereto. The side of the fixed plate 21 away from the energy dissipation unit 1 is fixedly connected to the channel steel 22.

[0030] The energy dissipation unit 1 is stably installed through the coordinated operation of the fixing plate 21 and the channel steel 22. The channel steel 22 is pre-embedded in the embankment body to form an anchoring foundation that penetrates deep into the embankment, providing reliable load-bearing support for overall fixation. The fixing plate 21 is tightly attached to the outer wall of the energy dissipation unit 1 and forms a firm connection with it. At the same time, the side away from the energy dissipation unit 1 is fixed to the channel steel 22 embedded in the embankment, so that the energy dissipation unit 1 is rigidly connected to the embankment body through the fixing plate 21 and the channel steel 22. This allows the force generated by the energy dissipation unit 1 when subjected to continuous wave impact to be transmitted to the channel steel 22 through the fixing plate 21, and then dispersed to the embankment body by the channel steel 22. This prevents the energy dissipation unit 1 from shifting, overturning or detaching from the embankment, providing a solid structural guarantee for the energy dissipation unit 1 to perform its wave dissipation function. The above connection method can increase the contact area, make the force more uniform, and reduce structural damage caused by local stress concentration. The channel steel 22 embedded in the embankment body can make full use of the embankment's load-bearing capacity, improve the overall impact resistance, and ensure that the device works stably for a long time under complex marine environment and wave impact.

[0031] When the application scenario is in shallow water or traditional dikes, the bottom of the channel steel 22 can extend vertically to the seabed, and be anchored by compacting the seabed or embedding it in rock. However, in deep-water marine engineering applications, to avoid increasing construction difficulty due to excessively long channel steel 22 caused by excessive water depth, a side-wall attached installation logic is adopted. The channel steel 22 and the fixing structure 2 are not directly rooted to the seabed, but are directly anchored to the main structure of the marine structure using high-strength bolts or welding. This installation method makes the wave-damping device an integral part of the marine structure, bearing wave loads along with the main structure, thus effectively solving the impractical engineering problem of auxiliary pile foundation construction in deep-water environments. The fixing plate 21 is preferably made of 6mm thick steel plate, its dimensions precisely matched to the outer wall curvature of the energy dissipation unit 1 to ensure a tight fit. The fixing plate 21, energy dissipation unit 1, and channel steel 22 are all connected by welding, and the welded joints are treated with anti-corrosion to prevent loosening due to corrosion, further ensuring the long-term stability of the fixing structure 2.

[0032] The spacing and arrangement of the energy dissipation units 1 allow for water flow channels, effectively dispersing the backflow energy of waves. If riprap or gabion cages are installed at the bottom of the energy dissipation units 1, filled with natural stones, an anti-erosion and bottom protection system for marine structure foundations is constructed. This system utilizes the flexible covering characteristics of gabion cages, tightly adhering to the muddy surface of the artificial island or platform base, preventing the downward flow of water caused by wave reflection from eroding the mud and sand of the base, and preventing the foundation from becoming suspended. Simultaneously, the mesh structure allows water to permeate and release pore water pressure, ensuring the stability of the marine engineering structure foundation while also considering compatibility with the marine environment.

[0033] like Figures 1 to 6As shown: There are multiple energy dissipation units 1, which are arranged in an alternating or matrix-like uniform distribution along the extension direction of the dike.

[0034] By setting up multiple energy dissipation units 1, a continuous and three-dimensional wave-dissipating protective zone is formed on the wave-facing side of the device. When incident waves act on this protective zone, the gaps 11 of each energy dissipation unit 1 independently reflect and diffract wave energy. At the same time, a specific spacing and layout relationship are formed between two adjacent energy dissipation units 1, allowing the reflected and diffracted waves generated by the previous unit to intersect with the relevant wave bodies of the subsequent unit, further causing interference and collision. The staggered or matrix distribution allows wave energy to be weakened layer by layer in the space formed by multiple units, preventing waves from directly penetrating through the gaps between units and ensuring that all areas on the wave-facing side of the embankment are uniformly protected. Compared with a single energy dissipation unit 1, the continuous distribution... The structure can fully cover the wave-facing surface of the breakwater, effectively filling the weak areas of a single unit protection and coping with incident waves of different wavelengths and angles. The flexibility of the staggered or matrix distribution allows it to adapt to the extension length and shape changes of the protection body, meeting the protection needs of different marine structures without changing the structure of the energy dissipation unit 1 itself. At the same time, multiple units share the impact force of the waves, avoiding damage to a single energy dissipation unit 1 due to concentrated force, improving the overall structural stability and service life of the device. The modular distribution also makes it easy to adjust the number or density of units according to the protection needs of different sections of the project without affecting the integrity of the overall protection system. Construction and subsequent maintenance are also convenient and efficient.

[0035] like Figures 1 to 6 As shown: The device also includes a drainage component 12 for timely drainage of water that accumulates in the cavity of the energy dissipation unit 1 and around the device after being impacted by waves.

[0036] When waves impact the device, some waves will flow into the inner cavity of the energy dissipation unit 1, while some waves will accumulate water around the device. The drainage component 12 provides a smooth drainage channel for the accumulated water by connecting the wave-facing side and the wave-repelling side of the energy dissipation unit 1, allowing the accumulated seawater to leave the inner cavity of the energy dissipation unit 1 and the surrounding area in a timely manner, avoiding prolonged water retention. This solves the hidden dangers caused by water retention after wave impact, reduces the additional pressure of water on the energy dissipation unit 1 and the fixed structure 2, avoids deformation and loosening of the structure due to long-term water load, and reduces the risk of structural corrosion caused by water immersion. Timely drainage does not affect the energy dissipation unit 1's wave reflection and diffraction energy dissipation effect, allowing the wave dissipation function and drainage function to work together to further improve the overall wave and erosion resistance reliability of the device, ensuring that the device maintains a good working condition under long-term wave action and providing continuous and effective protection for the shoreline.

[0037] like Figures 1 to 6As shown: The drainage component 12 is a drainage pipe 121 that connects to the adjacent energy dissipation unit 1.

[0038] The drainage pipe 121 serves as the drainage component 12, with both ends connected to adjacent energy dissipation units 1. This allows multiple energy dissipation units 1 to form an interconnected drainage system. After waves impact the device, the water accumulated in and around the interior of each energy dissipation unit 1 can be quickly discharged through the interconnected drainage pipe 121. This prevents water stagnation in individual energy dissipation units 1 and balances the water pressure through the connecting channels between adjacent units, making the drainage process smoother and more efficient. Furthermore, the connection method of the drainage pipe 121 does not interfere with the reflection and diffraction wave-dissipating effects of each energy dissipation unit 1, ensuring that wave dissipation and drainage functions do not conflict. The overall integrity among multiple energy dissipation units 1 is enhanced, enabling the dispersed energy dissipation units 1 to form a protective system that works together to withstand forces. This improves the overall structural stability of the device and prevents individual energy dissipation units 1 from shifting or loosening under strong wave impact. At the same time, the interconnected drainage pipe 121 does not require an additional independent fixing structure 2. It can be fixed by assembling adjacent energy dissipation units 1, which simplifies the overall structure of the device. The prefabricated drainage pipe 121 can be spliced ​​and installed on site simultaneously with the energy dissipation units 1, making construction convenient and efficient. If the drainage pipe 121 is damaged later, it can be disassembled and replaced separately without affecting the normal use of adjacent energy dissipation units 1 and the overall protective effect, further reducing maintenance costs.

[0039] like Figures 1 to 6 As shown: The drainage component 12 is a drainage hole 122 opened on the wall of the energy dissipation unit 1.

[0040] The drain hole 122 is directly formed on the wall of the energy dissipation unit 1, connecting the inner cavity of the energy dissipation unit 1 with the external environment. When waves impact the device, water that flows into the inner cavity of the energy dissipation unit 1 and accumulates around the device can be directly discharged outward through the drain hole 122 on the wall, completing the drainage without the need for additional connecting pipes. The location and size of the drain hole 122 are adapted to the wave dissipation requirements of the energy dissipation unit 1, without damaging the structure's own reflection and diffraction functions, ensuring that the weakening of wave energy and the drainage of accumulated water do not interfere with each other, achieving simultaneous wave dissipation and drainage. The drain hole 122 is an integrated structural feature, eliminating the risk of pipe detachment or leakage, resulting in higher structural reliability. Later maintenance only requires cleaning any blocked drain holes 122, making the operation simple. Moreover, the maintenance of a single drain hole 122 will not affect the overall protective function of the energy dissipation unit 1, ensuring that the device continues to perform its wave-proof and erosion-proof functions stably.

[0041] It should be noted that when the embankment is a gentle slope of 60°, drainage pipe 121 is prioritized. Drainage pipe 121 is made of corrosion-resistant material and is sealed at both ends to energy dissipation unit 1 to ensure rapid drainage of accumulated water. At the same time, drainage pipe 121 enhances the overall integrity between multiple units. When the embankment is a vertical steep slope of 90°, the drainage pipe 121 structure is eliminated, and drainage holes 122 are only opened on the wall of energy dissipation unit 1. This avoids the problems of inconvenient installation and easy impact damage of drainage pipe 121 in steep slope environments. Drainage holes 122 are evenly distributed on the structural wall to ensure comprehensive and rapid drainage of accumulated water.

[0042] like Figures 1 to 6 As shown: A sacrificial anode block 13 is also provided on the energy dissipation unit 1.

[0043] Based on the principle of electrochemical corrosion, a natural electric couple is formed in the seawater environment by utilizing the difference in the activity of the two metals. The sacrificial anode block 13 will preferentially undergo oxidation corrosion reaction, and prevent the energy dissipation unit 1 from corroding through its own consumption. At the same time, a stable protective state is formed on the surface of the steel structure, avoiding damage to the energy dissipation unit 1 caused by the strong corrosiveness of seawater. In addition, the placement of the sacrificial anode block 13 avoids the critical wave-facing area of ​​the energy dissipation unit 1, and will not interfere with its wave reflection and diffraction energy dissipation effect, ensuring that the anti-corrosion function and the wave dissipation function work together.

[0044] The sacrificial anode block 13 is preferably a zinc block. By selecting a zinc block as the sacrificial anode block 13, the protection requirements of the highly corrosive marine environment are met. The metallic activity of zinc is suitable for the anti-corrosion requirements of the energy dissipation unit 1, and the anti-corrosion effect is stable and long-lasting. It can provide reliable and targeted protection for the steel structure, forming a dual protection system with the anti-corrosion coating that may exist on the steel structure, further improving the durability and service life of the device in complex marine environments. Zinc blocks are readily available and cost-effective, and the fixed installation method is simple and reliable. No additional power supply or complex supporting equipment is required. Continuous anti-corrosion can be achieved by relying on natural galvanic reaction. In the later maintenance, only the consumed zinc blocks need to be disassembled and replaced individually. The operation is simple and efficient and will not affect the overall structure, connection stability and protective effect of the energy dissipation unit 1. It effectively reduces maintenance costs and difficulties and ensures that the device can play a long-term stable role in wave protection and erosion prevention.

[0045] The sacrificial anode block 13 is preferably fixed at the top of the energy dissipation unit 1. This position avoids the wave-facing core area, thus not affecting wave reflection and diffraction, and also facilitates later inspection and maintenance. Each zinc block preferably weighs 5 kg. The number installed can be flexibly adjusted according to the corrosion intensity of the sea area where the dike is located, the purity of the zinc blocks themselves, and the expected maintenance cycle. The number can be increased in areas with strong seawater corrosion, and appropriately reduced in areas with weak corrosion or high maintenance frequency, ensuring that the sacrificial anode block 13 can continuously provide corrosion protection for the energy dissipation unit 1. During later maintenance, there is no need to disassemble the main structure of the energy dissipation unit 1; only the consumed zinc blocks need to be individually removed and replaced. The operation is simple and efficient, does not affect the overall protective effect of the device, and significantly reduces maintenance costs and downtime.

[0046] like Figures 1 to 6 As shown: the angle of the gap 11 of multiple energy dissipation units 1 can be adapted and adjusted according to the wave wavelength and wave height of the sea area where the dike is located, and the direction of the gap 11 is towards the main propagation direction of the incident wave.

[0047] The angle of the gaps 11 of multiple energy dissipation units 1 is adapted to the actual wave wavelength and wave height of the sea area where the dike is located. The direction of the gaps 11 of all energy dissipation units 1 is uniformly oriented towards the main propagation direction of the incident wave, so that each energy dissipation unit 1 can accurately connect with the impact path of the sea wave. When the sea wave acts on the structure, it can be more efficiently guided to the inner cavity of the energy dissipation unit 1. The reflected wave formed by the reflection of the inner wall can collide with the subsequent incident wave. At the same time, the diffracted wave generated along the outer wall can also effectively interfere with the wave body of the adjacent unit. This avoids the problem of insufficient wave energy attenuation caused by the mismatch between the angle of the gap 11 and the wave condition, and ensures that multiple energy dissipation units 1 can work together to play a wave dissipation role under different wave conditions.

[0048] By adapting and adjusting the angle of notch 11 and unifying its direction, the device can flexibly adapt to the wave characteristics of different sea areas, greatly improving the targeting and effectiveness of wave dissipation and erosion prevention. This avoids the limitation that a single fixed notch 11 angle is insufficient to cope with complex wave conditions. The angle adjustment does not require changing the core structure and fixing method of the energy dissipation unit 1. It can be adapted based on the existing assembly foundation, making the operation simple and not affecting the overall stability of the device. At the same time, with the synergy of the fixing structure 2, the adjusted energy dissipation unit 1 can still maintain a stable installation state, which not only improves the adaptability of the device to different marine environments, but also ensures the reliability of protection during long-term use, extending the applicability and service life of the device.

[0049] The energy dissipation unit is a steel structure. The steel structure of the energy dissipation unit 1 uses a specially made tube with an outer diameter of 1000 mm and a wall thickness of 20 mm.

[0050] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
