Description

Technical Field

[0001] The present application relates to the field of coastal and marine engineering technology, and in particular to a gravity-type semicircular ecological landscape breakwater with multiple nested walls and openings. Background Art

[0002] Breakwaters are an important type of marine engineering structure that resists wave invasion and protects the stability of the waters in the harbor and the coastline. Semicircular breakwaters are a typical type of breakwater, which have the advantages of beautiful appearance, high anti-tilting and anti-sliding capabilities, light weight, suitability for poor foundation conditions such as silt, and high cross-sectional economy. However, the semicircular cross-sectional characteristics make it easy for top overtopping to occur under strong wave conditions, and due to the cross-sectional shape of the embankment, the semicircular top is not conducive to the passage of vehicles and personnel. In addition, the traditional breakwater design only considers the structure's ability to resist wave invasion but ignores its eco-friendliness and landscape effect, which has a negative impact on the marine ecological environment and biodiversity.

[0003] In the related art, a Chinese patent with application number CN202510192435.9 proposes a type of wave energy conversion twin semicircular dike, including two semicircular breakwaters overlapping front and back, with baffles and energy conversion modules arranged at the overlap. The semicircular dike on the wave-facing side and the baffle enclose a front air chamber, and the semicircular dike on the wave-back side and the baffle enclose a rear air chamber. The baffle is provided with a narrow opening to connect the front and rear air chambers. Furthermore, the front air chamber is connected to the energy conversion module, and a water inlet is provided on the outer wall of the front air chamber to introduce waves into the air chamber. The twin semicircular dike organically integrates the semicircular dike with wave energy power generation, breaking through the single function limitation of the traditional semicircular dike that can only break waves.

[0004] Although the above-mentioned wave energy conversion twin semicircular breakwaters have made certain breakthroughs in functional integration, from the perspective of overall design, there are still some shortcomings that need to be addressed. For example, this type of breakwater has not yet overcome the long-standing problems faced by traditional semicircular breakwaters, such as wave overtopping on the top of the breakwater and low efficiency in the use of the top space; at the same time, this type of breakwater is still more inclined to the traditional breakwater design concept in terms of functional design, and has not fully reflected the ecologically friendly development concept of providing more habitats for marine life and improving biodiversity in the current stage of coastal structure development, and has limited effect on the restoration of marine ecosystems. Summary of the invention

[0005] In order to improve the problems of traditional breakwaters such as wave overtopping and inadequate utilization of the top space, as well as the difficulty in complying with the concept of eco-friendly development, the present application provides a gravity-type semi-circular ecological landscape breakwater with multiple nested walls.

[0006] The application provides a multi-wall nested gravity-type semicircular ecological landscape breakwater that adopts the following technical solutions: A gravity-type open-hole semi-circular ecological landscape breakwater with multiple nested walls, including a bottom plate, on which are provided: A breakwater, which includes an inner semi-circular breakwater, several middle arc-shaped breakwaters, and an outer arc-shaped breakwater that are successively sleeved at intervals and have gradually decreasing center angles. A wave dissipation cavity is formed between adjacent two arc-shaped breakwaters. The inner side of the inner semi-circular breakwater is a structural cavity. The back wave side of the arc-shaped breakwater is fixedly connected to the bottom plate; Side walls, provided on both sides of the breakwater, for enclosing the structural cavity and all the wave dissipation cavities; Partition walls, fixedly connected between the bottom plate and the inner semi-circular breakwater and extending upward to connect the upper arc-shaped breakwaters. A plurality of first water passing holes are penetrated through the partition walls, and a plurality of second water passing holes are provided near the bottom plate of the arc-shaped breakwaters; A groove structure, provided on the surface of the bottom plate on the side away from the outer arc-shaped breakwater; and A trestle structure, installed on the top of the outer arc-shaped breakwater.

[0007] Furthermore, a plurality of third water passing holes are provided circumferentially on the arc wall surfaces of the inner semi-circular breakwater and the middle arc-shaped breakwaters.

[0008] Furthermore, both the first water passing holes and the second water passing holes are long holes arranged along the axial direction of the inner semi-circular breakwater.

[0009] Furthermore, a partition grid is provided on the outer arc side of the arc-shaped breakwater, and the partition grid has grooves for planting vegetation or providing habitats for marine organisms.

[0010] Furthermore, the top of the inner semi-circular breakwater is higher than the designed low water level of the acting water area, and the top of the outer arc-shaped breakwater is higher than the designed warning water level of the acting water area.

[0011] Furthermore, the partition wall is provided with an overtopping entry channel communicating with the corresponding wave dissipation cavity at the position corresponding to the wave dissipation cavity.

[0012] Furthermore, a plurality of the first water passing holes are provided at the upper, middle, and lower parts of the position of the partition wall in the structural cavity.

[0013] Furthermore, the bottom plate is provided with pressure relief holes at the position corresponding to the structural cavity.

[0014] Furthermore, inclined surfaces are provided at both ends of the bottom plate along the radial direction of the breakwater, and a plurality of the groove structures are distributed on the inclined surfaces.

[0015] Furthermore, the trestle structure includes: Support piles are located on the leeward side of the breakwater, and their tops are flush with the crown of the outer arc-shaped breakwater or the top of the partition wall; The trestle floor slab is laid between the crown of the outer arc-shaped breakwater or the partition wall top and the support piles; and The trestle guardrail is installed on the side of the trestle floor slab.

[0016] In summary, the present application includes at least one of the following beneficial technical effects: 1. The present application proposes a wave dissipation method with nested multiple arc-shaped walls to solve the problem of overtopping at the top of traditional breakwaters; when facing large waves, the phenomenon of overtopping at the top of traditional breakwaters is frequent, which not only affects the structural safety but may also cause damage to the surrounding areas. The breakwater structure of the present invention adopts a circular arc-shaped perforated wall surface with three layers nested, stacked in a staggered manner and having a certain gap between them. Through the coupling effect of flow diversion - energy dissipation of the perforated arc-shaped wall surface and the hierarchical energy dissipation mechanism of multiple staggered walls, the potential overtopping water flow is successively introduced into the breakwater chamber, ensuring that there is no overtopping on the outside of the crown of the outer arc-shaped breakwater; 2. Affected by overtopping, the space at the top of traditional breakwaters is often not fully utilized, resulting in a certain waste of resources. On the basis of solving the overtopping problem, the present application realizes the effective development of this part of the space by setting a trestle structure at the top of the breakwater, which not only provides an excellent viewing platform for tourists, enabling them to enjoy the sea view up close and meeting the hydrophilic needs of tourists, but also further improves the practicality and attractiveness of the breakwater; 3. The present application breaks through the limitation that traditional breakwaters only have the function of wave dissipation, and realizes the organic unity of wave dissipation, ecological friendliness and excellent landscape. On the one hand, by setting partition grid structures and groove structures on the surface and bottom plate of the breakwater, the inside can be filled with soil for planting plants, and it can also provide rich habitats, attachment and reproduction spaces for marine organisms; on the other hand, a small amount of artificial ecological reefs can be filled in the breakwater chamber, which not only further enhances the structural stability, but also provides a suitable substrate for the growth of marine plants, thereby promoting the development of marine biodiversity; 4. The present application mainly uses semi-circular structures as basic components, and the overall structure is simple and beautiful, with high design rationality; in terms of construction, it can be fabricated in a segmented prefabrication method in the factory. This method has many advantages: first, the cost is low, which can effectively control the project cost; second, it is less affected by on-site construction conditions, reducing construction delays and quality problems caused by on-site factors such as bad weather and complex terrain; finally, the construction is convenient and fast, and each prefabricated section can be produced with high quality in the factory, transported to the site and quickly assembled, greatly shortening the construction period and improving the construction efficiency.

[0020] To make the objectives, technical solutions and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention in conjunction with the attached drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0021] Referring to Figure 1 、 Figure 2 and Figure 3 , the embodiment of the present application discloses a gravity type open-hole semi-circular ecological landscape breakwater with multiple nested walls, which includes a bottom plate 5, and the following are arranged on the bottom plate 5: A breakwater, which includes an inner semi-circular breakwater 1, several middle arc-shaped breakwaters 2, and an outer arc-shaped breakwater 3 that are successively sleeved at intervals and have gradually decreasing central angles. A wave-dissipating cavity 17 is formed between adjacent two arc-shaped breakwaters. The inner side of the inner semi-circular breakwater 1 is a structural cavity 18. The wave-facing side of the arc-shaped breakwater is fixedly connected to the bottom plate 5, so that multiple wave-dissipating channels with open head ends and gradually decreasing total arc lengths from bottom to top are formed on the wave-facing side of the breakwater.

[0022] It should be specifically noted that in specific configurations, the middle arc-shaped breakwater 2 can be set to one or multiple. In this embodiment, one is taken as an example, but it does not represent a limitation on its quantity. The arc-shaped breakwater refers to one or the whole of the inner semi-circular breakwater 1, the middle arc-shaped breakwater 2, and the outer arc-shaped breakwater 3, which is a substitute name and will not be further explained later. In addition, the inner semi-circular breakwater 1, the middle arc-shaped breakwater 2, and the outer arc-shaped breakwater 3 can be coaxially arranged or have misaligned axes. If they are misaligned, the axes of the inner semi-circular breakwater 1, the middle arc-shaped breakwater 2, and the outer arc-shaped breakwater 3 are successively spaced along the wave surge direction, which can increase the span of the breakwater and reduce the arch height. In this embodiment, all arc-shaped breakwaters are coaxially arranged as an example.

[0023] Side walls 4 are arranged on both axial sides of the breakwater to enclose the structural cavity 18 and all wave-dissipating cavities 17, which can effectively prevent waves from impacting the breakwater structure from the side and enhance the overall stability of the structure.

[0024] Partition walls 12 are fixedly connected between the bottom plate 5 and the inner semi-circular breakwater 1 and extend upward to connect to the upper arc-shaped breakwater. A plurality of first water passing holes 13 are penetrated through the partition walls 12, and a plurality of second water passing holes 15 are opened at the position of the arc-shaped breakwater close to the bottom plate 5. Specifically, a plurality of first water passing holes 13 are provided at the upper, middle, and lower parts of the partition walls 12 located in the structural cavity 18, and overtopping entry channels 16 communicating with the corresponding wave-dissipating cavities 17 are opened at the positions of the partition walls 12 corresponding to the wave-dissipating cavities 17.

[0025] A groove structure 9 is arranged on the surface of the bottom plate 5 on the side away from the outer arc-shaped breakwater 3. This structure simulates the shape of natural reefs, provides an ideal attachment place for marine organisms, is conducive to the reproduction and habitat of marine organisms, promotes the diverse development of the marine ecosystem, and reflects the eco-friendly characteristics of the breakwater in this application.

[0026] A trestle structure is installed on the top of the outer arc-shaped breakwater 3.

[0027] And, referring to Figure 2 and Figure 3, a plurality of third water holes 10 are provided in the circumferential direction of the arc wall surface of the inner semicircular breakwater 1 and the middle arc breakwater 2. Among them, the first water hole 13 and the second water hole 15 are both long holes arranged along the axial direction of the inner semicircular breakwater 1, and the third water hole 10 is a regular hole, which can be a round hole, a square hole, etc.; the first water hole 13 and the second water hole 15 are arranged at intervals, and the third water hole 10 is arranged in an array. The size, spacing and shape of the first water hole 13 and the second water hole 15 are determined according to the wave parameters of the sea area where the breakwater is located and the overall energy dissipation requirements of the structure. Reasonable spacing can ensure that the waves flow smoothly between the chambers and the energy distribution is uniform.

[0028] Therefore, because the center angles of the inner semicircular breakwater 1, the middle arc-shaped breakwater 2 and the outer arc-shaped breakwater 3 decrease successively, this design not only forms a unique sense of hierarchy in the structure, but also creates a visual staggered effect, enhancing the aesthetics of the breakwater. In terms of spatial layout, the arc-shaped breakwaters are arranged in a stacked manner, and wave-breaking cavities 17 are formed between the arc-shaped breakwaters. When waves act on the breakwater structure, the inner semicircular breakwater 1 first contacts the waves and produces an initial wave-breaking effect; if part of the water flows over its top, it is affected by the diversion-energy dissipation effect of the wave-breaking cavity 17 between the middle arc-shaped breakwater 2 and the inner semicircular breakwater 1, and is forced into the structure cavity 18 through the wave-breaking channel between the two and the multiple second water holes 15 at the end of the channel.

[0029] If a small amount of water flows over the outer wall of the middle arc-shaped breakwater 2 during the above process, similarly, this part of the water flow will be affected by the diversion and energy dissipation effect of the wave-breaking cavity 17 on the outer side of the middle arc-shaped breakwater 2 and the inner side of the outer arc-shaped breakwater 3, and will be gradually forced into the interior of the structural cavity 18 through the wave-breaking channel between the two and multiple second water holes 15 at the end of the channel, thereby ensuring that no wave overtopping occurs on the top of the outer arc-shaped breakwater 3.

[0030] Each layer of the arc-shaped breakwater is tightly connected by the partition wall 12. The partition wall 12 is a concrete structure with a certain thickness, mainly playing the role of supporting the breakwater and the trestle structure to prevent the overturning and other forms of damage of these structures under extreme wave loads. At the same time, strip-shaped first water holes 13 are respectively arranged at different positions of the partition wall 12, which can ensure the water exchange capacity of each chamber inside the breakwater structure and between the inside and outside of the breakwater structure, enhance the connectivity of the water bodies inside and outside the breakwater structure, contribute to promoting water circulation, and maintaining the material and energy exchange of the marine ecosystem. Moreover, the partition wall 12 with the first water holes 13 and the arc-shaped breakwater with the second water holes 15 actually form a multi-porous structure. When the wave passes through the multi-porous structure, the breaking phenomenon is more significant, thereby improving the energy dissipation efficiency. Specifically, the setting of the first water holes 13 and the second water holes 15 breaks the relatively closed state of the front and rear chambers inside the breakwater, enhances the connectivity between the chambers, enables the water body to flow freely between different chambers during the propagation and dissipation of the wave inside the breakwater structure, and further improves the wave dissipation performance of the breakwater.

[0031] Moreover, only the third water holes 10 are opened on the inner-layer semi-circular breakwater 1 and the middle-layer circular arc breakwater 2. On the one hand, it can enhance the wave dissipation effect of the breakwater; when the wave acts on the breakwater, part of the water flow will flow into the interior of the structure chamber 18 through the third water holes 10, and turbulence and vortices will be generated during this process, thereby promoting the breaking of the wave and enhancing the wave dissipation effect. On the other hand, the third water holes 10 are conducive to the seawater exchange between the inside and outside of the breakwater structure, avoiding the formation of a closed dead zone, and contributing to maintaining the ecological balance of this structural area. The surface of the outer-layer circular arc breakwater 3 is not provided with the third water holes 10. This is a measure taken in consideration of the wave dissipation function requirements and the landscape function on the outside of the structure, because the design of the third water holes 10 on the outer-layer circular arc breakwater 3 may cause a small amount of waves to climb onto the trestle and pour into the area behind the breakwater, which will affect the hydrophilic experience of tourists and the sheltering effect of the area behind the structure.

[0032] Furthermore, the main structure of this breakwater structure is a semi-circular arc member. This semi-circular arc design not only has reasonable structural stress and can effectively disperse the wave impact force, but also has a regular and simple shape, with significant prefabrication advantages. At the same time, through factory segmented prefabrication and further splicing of the prefabricated segments according to the on-site situation, the construction efficiency is guaranteed. The prefabricated components are made of high-strength and corrosion-resistant concrete or new composite materials to ensure that the components have sufficient strength and durability in the harsh marine environment.

[0033] In addition, to further enhance the ecological effect of the breakwater of this application, referring to Figure 3 and Figure 4, a partition grid 11 is provided on the outer arc side of the arc-shaped breakwater, and the partition grid 11 has grooves for planting vegetation or providing habitats for marine organisms. Moreover, inclined surfaces are provided at both ends of the bottom plate 5 along the radial direction of the breakwater, and a plurality of groove structures 9 are distributed on the inclined surfaces. These grooves can be filled with a soil layer and planted with a vegetation layer, or can provide habitats for marine organisms, thereby promoting ecological friendliness and achieving a landscape effect.

[0034] Alternatively, in other feasible embodiments, a small amount of artificial ecological reefs can be further filled in the structural cavity 18 to enhance the structural stability, and these boulders can also play the role of triggering wave breaking and providing biological habitats.

[0035] Moreover, the top of the inner semi-circular breakwater 1 is higher than the designed low water level of the acting water area, and the top of the outer arc-shaped breakwater 3 is higher than the designed warning water level of the acting water area; a pressure relief hole 14 is provided at the position of the bottom plate 5 corresponding to the structural cavity 18.

[0036] In this way, the bottom plate 5 plays a role in supporting the structure in the overall breakwater structure, and its design also fully considers pressure balance and ecological requirements; and when there is a pressure difference inside and outside the breakwater, the pressure relief hole 14 can balance the pressure in time to prevent the structure from being damaged due to excessive pressure, ensuring the safety and stability of the breakwater in a complex marine environment.

[0037] In addition, referring to Figure 1 and Figure 5 , the above-mentioned trestle structure includes: Support piles 7, located on the leeward side of the breakwater, and the top is flush with the crown of the outer arc-shaped breakwater 3 or the top of the partition wall 12; it provides a stable supporting force for the trestle structure and ensures the safety of the trestle structure under the action of waves.

[0038] The trestle bottom plate 6 is erected between the crown of the outer arc-shaped breakwater 3 or the top of the partition wall 12 and the support piles 7, forming a solid whole.

[0039] The trestle guardrail 8 is installed on the side of the trestle bottom plate 6, specifically at the front and rear edges of the trestle bottom plate 6, providing safety protection for tourists, and at the same time playing a decorative role, making the trestle integrate with the marine environment and becoming a beautiful landscape.

[0040] Thus, after a plurality of prefabricated breakwater structure segments are combined, they can be arranged in the waters along the line to form a breakwater line integrating wave dissipation, ecological friendliness and excellent landscape, as Figure 6 shown.

[0041] The implementation principle of a multi-wall nested gravity type open-hole semi-circular ecological landscape breakwater in an embodiment of the present application is: When waves act on this breakwater, wave dissipation is mainly achieved through the wave reflection effect of the triple circular arc breakwater wall surface mentioned above, as well as the wave breaking effect caused by the second water passage holes 15, the third water passage holes 10 opened on the wall surface and the internal chambers of the structure. During the wave dissipation process, the waves will first come into contact with the outer wall surface of the inner semi-circular breakwater 1; if the wave conditions are relatively severe, overtopping may occur at the top of this wall surface. However, this part of the overtopping flow is diverted in the wave dissipation chamber 17 between the inner semi-circular breakwater 1 and the middle semi-circular wave breakwater, and its energy is weakened through the combined energy-consuming effects of the third water passage holes 10, the partition grids 11 opened on the wall surface, and the internal vegetation and marine organisms, and finally flows into the interior of the structure chamber 18 through the wave dissipation channel.

[0042] If the wave intensity further increases, overtopping may also occur on the outer surface of the wall of the middle circular arc breakwater 2; similarly, this part of the overtopping flow will be diverted and energy-consuming by the wave dissipation chamber 17 and flow into the interior of the structure chamber 18 through the wave dissipation channel, thus ensuring that overtopping does not occur on the outer side of the top of the outer circular arc breakwater wall of the structure. The first water passage holes 13 opened in the lower and middle parts of the partition wall 12 in the structure chamber 18 of the breakwater and the second water passage holes 15 opened at the lower parts of each circular arc breakwater can play a role in connecting the water bodies and gases inside and outside the breakwater to prevent excessive pressure differences inside and outside the structure during the wave dissipation process. At the same time, the partition grids 11 arranged on the surface of the circular arc breakwater and the surface of the groove structure 9 opened at the end of the bottom plate 5 are rough. On the one hand, they provide habitats for marine animals and plants, and on the other hand, they can also play a role in wave dissipation to a certain extent. Further, a small amount of artificial ecological reefs can be filled inside the breakwater during the construction process to enhance the structural stability, and these boulders can also play a role in triggering wave breaking and providing habitats for organisms.

[0043] The staggered circular arc visual effect after the completion of this breakwater and the vegetation crops planted on its outer surface have certain landscape characteristics compared with the traditional breakwater structure, and overtopping does not occur on the outermost breakwater. Therefore, the top space of the outermost breakwater can be fully utilized to arrange a trestle, so as to facilitate tourists to get close to the marine ecosystem.

[0044] The main breakwater component adopted in the present invention is designed with an arc-shaped structure, with a simple and smooth geometric shape. The main structure is made of high-strength concrete materials. During the production process of the component, a modular segmented prefabrication process is adopted, which can significantly improve the manufacturing efficiency and quality control level. For a small number of accessory structural components, on-site casting construction methods are used to ensure the adaptability and functionality of the overall structural system. Compared with the traditional semi-circular breakwater structure, while inheriting its excellent anti-overturning, anti-sliding performance and good landscape coordination, the present invention breaks through two major bottlenecks of traditional technologies through innovative structural design. On the one hand, a new wave dissipation structure system is adopted to significantly reduce the overtopping volume at the top and improve the hydraulic performance of the breakwater. On the other hand, an ecological design concept is introduced to construct a bionic foundation structure and a marine organism attachment interface, which can effectively improve the ecological connectivity of the sea area while ensuring the wave prevention function, and achieve the harmonious coexistence of marine engineering facilities and the ecological environment.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, such modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
