Description

Technical Field

[0001] The present invention relates to the field of river bank protection, and in particular to a wave-breaking structure and a bank protection. Background Art

[0002] Traditional navigable rivers are subject to the impact of ship waves. Within the range of ship waves, riverbanks and slope protection are often designed as rigid structures to resist wave erosion. Traditional designs generally use reinforced concrete or mortar-stone retaining walls, and plain concrete or mortar-stone slope protection. Due to the large fluctuations in river water levels, traditional bank and slope protection structures are often tall and wide.

[0003] Traditional reinforced concrete and mortar-masonry retaining walls harden river channels. Their rigid structures restrict the planting of landscape plants, block the water exchange between water and land, and destroy the connectivity of the ecosystem. Traditional revetments have poor ecological properties and reduce the landscape effect of the river. In addition, retaining walls of fixed height cannot be adjusted with changes in water levels. They are insufficient to dissipate waves at high water levels and block sight at low water levels. They have a weak ability to adapt to water level fluctuations. Ship waves in navigable rivers scour the revetments, causing the impact of ship waves, which threatens the stability of the bank slope and the survival of landscape plants. Summary of the Invention

[0004] In view of this, the present invention provides a wave-breaking structure and a revetment to solve the problems raised by the above-mentioned background technology.

[0005] In a first aspect, the present invention provides a wave-breaking structure comprising:

[0006] A revetment retaining wall is suitable for being arranged along the extending direction of a river channel, the revetment retaining wall comprising a water-facing side wall body and a soil-facing side wall body, the water-facing side wall body and the soil-facing side wall body being spaced apart to form an accommodation space, the water-facing side wall body being provided with a water-permeable hole, the water-permeable hole being connected to the accommodation space;

[0007] A plurality of wave-breaking water tanks are arranged in the accommodation space; the wave-breaking water tanks include a box body and a wave-breaking channel, the wave-breaking channel is arranged to pass through the box body from front to back, and the wave-breaking channel is used to connect the river channel and the landscape plant area on the river channel land;

[0008] Among them, the water flow in the river channel can enter or flow out of the accommodating space through the water permeable holes, so that all the wave-breaking water tanks float up and down in the accommodating space as the water level of the river channel changes, and make the waves on the river channel surface overlap with the wave-breaking channels.

[0009] Beneficial effects: When the water level in the river changes, water flows in and out of the holding space through the water permeable holes, and the buoyancy of the wave-breaking water tank adaptively rises and falls, so that the wave-breaking channel continues to align with the wave surface, and the wave energy is dispersed and consumed by the floating damping of the wave-breaking channel and the wave-breaking water tank, thereby achieving the purpose of reducing the impact on the revetment; water flows into the holding space through the water permeable holes to consume energy, and at the same time is broken for the second time by the wave-breaking channel of the floating water tank, which significantly weakens the scouring force of the ship's waves; this application uses the wave-breaking water tank to float with the water level, so that the wave-breaking channel always overlaps with the water surface. The design of adaptive water level fluctuation solves the problem that the traditional retaining wall with a fixed height is insufficient to eliminate waves at high water levels and blocks the line of sight at low water levels; the wave-breaking channel is used to connect the water area and the terrestrial landscape plant area, thereby improving ecological connectivity, promoting water exchange and biological migration, and solving the ecological problems of hard structure barriers.

[0010] In some embodiments, the revetment retaining wall also includes a retaining wall bottom plate, the water side wall body and the soil side wall body are fixedly arranged on the upper side of the retaining wall bottom plate, and the retaining wall bottom plate, the water side wall body and the soil side wall body are jointly constructed to form the accommodating space.

[0011] Beneficial effects: The retaining wall bottom plate, the water-side wall and the soil-side wall jointly form a holding space, which can prevent riverbed sediment from invading the floating holding space of the wave-breaking water tank, ensuring the smooth movement of the wave-breaking water tank; in addition, it is beneficial to enhance the overall stability of the bank retaining wall and resist the lateral thrust of ship waves.

[0012] In some embodiments, the retaining wall base plate includes a first base plate and a second base plate that are fixedly arranged. The first base plate is suitable for being buried in the riverbed, and the second base plate is suitable for being buried in the river channel land. The buried width of the second base plate is greater than the buried width of the first base plate.

[0013] Beneficial effects: The first bottom plate serves as the riverbed anchoring section, and the second bottom plate serves as the land anchoring section. Both are arranged along the extension direction of the river channel. The resistance of the land soil can be used to balance the lateral wave pressure near the water to prevent the retaining wall from overturning. The integrity of the bank retaining wall is improved by the fixed first and second bottom plates, avoiding adverse settlement that affects the spatial size of the accommodation space and meeting the floating requirements of the wave-breaking water tank.

[0014] In some embodiments, the bank retaining wall is configured as a reinforced concrete cantilever structure.

[0015] Beneficial effects: The cantilever reinforced concrete structure facilitates template construction, reduces the difficulty of on-site pouring, and has good construction economy.

[0016] In some embodiments, the top elevation of the soil-facing side wall is higher than the ground line of the river channel land area.

[0017] Beneficial effects: The wall on the soil side is higher than the land surface to prevent high water level overflow and protect the landscape plant area; and when the water level recedes during overflow, the wall on the soil side can intercept part of the water flow to ensure the local water environment of the landscape plant area.

[0018] In some embodiments, at least one wave-breaking channel is provided, and the wave-breaking channel is provided as a grating structure.

[0019] Beneficial effects: The bar structure expands the flow area and breaks waves through disturbance; in addition, the gaps in the bar structure can provide habitats for small aquatic organisms, improving ecological performance.

[0020] In some embodiments, the box is configured as a hollow rectangular parallelepiped structure.

[0021] Beneficial effects: The box with a hollow rectangular structure can maximize the internal volume and provide sufficient buoyancy within a limited accommodation space; the geometric shape of the rectangular parallelepiped facilitates standardized production and arrangement, reducing manufacturing and construction costs.

[0022] In some embodiments, the box body is provided with a water injection port, and the water injection port is arranged on the upper end surface of the box body; the inner cavity of the box body and the wave elimination channel are separated;

[0023] Water is injected into the box through the water injection port so that the top of the wave-breaking water tank is higher than the accommodating space at a normal water level.

[0024] Beneficial effect: Water is poured into the wave-breaking water tank through the water inlet to adjust the deadweight of the wave-breaking water tank, ensuring that the accommodating space is exposed on the top of the wave-breaking water tank at normal water level, so that the wave-breaking channel is aligned with the wave surface and the wave-breaking effect is guaranteed.

[0025] In some embodiments, a connecting buckle assembly is provided on the box body, and a plurality of the wave-breaking water tanks are connected in series through the connecting buckle assembly;

[0026] The connecting buckle assembly includes a first plug buckle, a second plug buckle, a first plug slot and a second plug slot, wherein the first plug buckle and the first plug slot are arranged on both sides of the upper end of the box body, the second plug buckle and the second plug slot are arranged on both sides of the lower end of the box body, the first plug buckle and the second plug slot are arranged on the same side of the box body along the length direction of the accommodation space, and the second plug buckle and the first plug slot are arranged on the other same side of the box body along the length direction of the accommodation space;

[0027] The upper ends of any two adjacent wave-breaking water tanks are connected to the first plug-in groove, the corresponding second plug-in groove and the second plug-in groove through the corresponding first plug-in buckle, so that all the wave-breaking water tanks are continuously arranged along the extension direction of the river channel.

[0028] Beneficial effects: Multiple arranged wave-breaking water tanks are connected in series into a continuous wave-breaking belt through the connecting buckle assembly, which plays an overall coordinated wave-breaking effect and avoids the wave-breaking blind area caused by the offset of a single box; the installation can be completed by plugging the plug-in buckle into the plug-in slot. This plug-in buckle design realizes modular installation and adjustment and replacement, and its quick assembly reduces construction time.

[0029] In some embodiments, on the box body, the first plug-in buckle and the second plug-in slot on the same side are staggered up and down, and the second plug-in buckle and the first plug-in slot on the same side are staggered up and down.

[0030] Beneficial effects: The staggered connection buckles can resist the multi-directional impact of waves and prevent the boxes from being disengaged or twisted; and the connection and assembly are convenient.

[0031] In some embodiments, the water-permeable hole includes a first through hole and a second through hole, and either through hole is connected to the accommodating space;

[0032] The height of the first through hole is higher than that of the second through hole.

[0033] Beneficial effect: A dual-channel water circulation is established by using high and low-level water holes. The water flows in and out mainly through the first through hole at the high water level, which can avoid pressure accumulation in the accommodation space; the second through hole at the low water level is used to maintain a minimum water exchange, ensuring that the wave-breaking water tank can still float during the dry season, and ensuring the reliability of the wave-breaking water tank floating under full water level conditions.

[0046] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0047] The following combination Figures 1 to 3 , describing embodiments of the present invention.

[0048] According to an embodiment of the present invention, on the one hand, a wave-breaking structure is provided, such as Figure 1 As shown, it includes a bank retaining wall 2 and a wave-breaking water tank 3. The bank retaining wall 2 is suitable for being arranged along the extension direction of the river channel 1. The bank retaining wall 2 includes a water-facing side wall 22 and a soil-facing side wall 23. The water-facing side wall 22 and the soil-facing side wall 23 are spaced apart to form an accommodating space. A water-permeable hole 24 is provided on the water-facing side wall 22, and the water-permeable hole 24 is connected to the accommodating space. A plurality of wave-breaking water tanks 3 are provided, and a plurality of wave-breaking water tanks 3 are arranged in the accommodating space.

[0049] In this embodiment, if Figure 3As shown, the wave-breaking water tank 3 includes a box body 31 and a wave-breaking channel 32. The wave-breaking channel 32 is set through the box body 31, and the wave-breaking channel 32 is used to connect the river channel 1 and the landscape plant area 42 of the river channel land 4; wherein, the water flow in the river channel 1 can enter or flow out of the accommodating space through the permeable hole 24, so as to cause all the wave-breaking water tanks 3 to float up and down in the accommodating space as the water level of the river channel 1 changes, and make the waves on the river water surface 11 and the wave-breaking channel 32 overlap correspondingly.

[0050] The wave-breaking structure provided in this embodiment has the following characteristics: when the water level of the river channel 1 changes, water flows in and out of the accommodating space through the water-permeable holes 24, and the buoyancy of the wave-breaking water tank 3 adaptively rises and falls, so that the wave-breaking channel 32 is continuously aligned with the wave surface, and the wave energy is dispersed and consumed by the floating damping of the wave-breaking channel 32 and the wave-breaking water tank 3, thereby achieving the purpose of reducing the impact on the revetment; water flows into the accommodating space through the water-permeable holes 24 to consume energy, and at the same time is broken for the second time by the wave-breaking channel 32 of the floating water tank, which significantly weakens the scouring force of the ship's waves; the present application uses the wave-breaking water tank 3 to float with the water level, so that the wave-breaking channel 32 always overlaps with the water surface. The design of adaptive water level fluctuation solves the problem that the traditional retaining wall with a fixed height is insufficient in wave breaking at high water levels and blocks the line of sight at low water levels.

[0051] The wave-dissipating structure provided in this embodiment floats the wave-dissipating water tank 3 when the water level rises, reducing the impact of waves on the terrestrial landscape plants. When the water level drops, the wave-dissipating water tank 3 sinks to restore visual connectivity between the river surface 1 and the river land 4. Furthermore, the wave-dissipating channel 32 connects the water area with the terrestrial landscape plant area 42, enhancing ecological connectivity and promoting water exchange and biomass migration, thereby resolving the ecological barrier problem caused by rigid structures.

[0052] In a further embodiment, Figure 1 As shown, the revetment retaining wall 2 also includes a retaining wall base plate 21. A waterside wall body 22 and an earthside wall body 23 are both fixedly mounted on the upper side of the retaining wall base plate 21. The retaining wall base plate 21, the waterside wall body 22, and the earthside wall body 23 collectively form a storage space. This solution, by forming a storage space with the retaining wall base plate 21, the waterside wall body 22, and the earthside wall body 23, prevents sediment from the riverbed 12 from intruding into the storage space where the wave-breaking water tank 3 floats, ensuring smooth movement of the wave-breaking water tank 3. Furthermore, this solution helps enhance the overall stability of the revetment retaining wall 2 and resist the lateral thrust of ship waves.

[0053] In some embodiments, the retaining wall bottom plate 21 includes a fixed first bottom plate (not shown in the figure) and a second bottom plate (not shown in the figure), the first bottom plate is suitable for being buried in the riverbed 12, and the second bottom plate is suitable for being buried in the river land 4, and the buried width of the second bottom plate is greater than the buried width of the first bottom plate; Figure 1 As shown, the first base plate is Figure 1 The left side of the retaining wall bottom plate 21, the second bottom plate is Figure 1The right side portion of the retaining wall bottom plate 21 , the second bottom plate, is away from the first bottom plate and extends to the river land 4 .

[0054] Specifically, the first bottom plate serves as the anchoring section of the riverbed 12, and the second bottom plate serves as the land anchoring section. Both are arranged along the extension direction of the river channel 1. The resistance of the land soil can be used to balance the wave pressure on the water side to prevent the retaining wall from overturning; the water side wall 22 and the soil side wall 23 are both fixedly arranged on the upper side of the first bottom plate. The integrity of the bank retaining wall 2 is improved by the fixed first bottom plate and the second bottom plate, avoiding adverse settlement that affects the spatial size of the accommodation space and meeting the floating requirements of the wave-breaking water tank 3.

[0055] In some embodiments, the revetment retaining wall 2 is configured as a reinforced concrete cantilever structure. Specifically, the retaining wall base plate 21, the waterside wall 22, and the soilside wall 23 are cast together as a whole. This cantilever reinforced concrete structure facilitates template construction, reduces the difficulty of on-site casting, and improves construction economy.

[0056] In some embodiments, the top elevation of the soil-side wall 23 is higher than the river channel land surface line 41. Setting the soil-side wall 23 higher than the land surface prevents high water level overflow and protects the landscape plant area 42. Furthermore, when the water level recedes during overflow, the soil-side wall 23 can intercept some of the water flow, ensuring the local water environment of the landscape plant area 42. The river channel land surface line 41 can be set to a horizontal line.

[0057] In this embodiment, the top elevation of the revetment retaining wall 2 is not lower than the sum of the normal water level elevation and the wave height; and the top elevation of the revetment retaining wall 2 is higher than the intersection of the river land ground line 41 and the soil side wall 23.

[0058] In some embodiments, the water-permeable hole 24 includes a first through hole (not shown in the figure) and a second through hole (not shown in the figure), and either through hole is connected to the accommodating space; the height of the first through hole is higher than the height of the second through hole; the first through hole is arranged above the second through hole, and can be arranged directly above the second through hole or obliquely above the second through hole.

[0059] This design uses high and low water-permeable holes 24 to establish a dual-channel water circulation. The water flows in and out mainly through the first through hole at the high water level, which can avoid pressure accumulation in the accommodation space; the second through hole at the low water level is used to maintain a minimum water exchange, ensuring that the wave-breaking water tank 3 can still float during the dry season, and ensuring the reliability of the floating of the wave-breaking water tank 3 under full water level conditions.

[0060] In a specific embodiment, Figure 3As shown, a wave-breaking water tank 3 is provided with one or more wave-breaking channels 32. These channels 32 run through both the waterside and landside of the tank 31, enabling water exchange between the river surface 11 and the land. The channels 32 are configured as a grating structure, which expands the flow area and disrupts waves. Furthermore, the gaps between the gratings provide habitats for small aquatic organisms, enhancing ecological sustainability.

[0061] In some embodiments, the box 31 is configured as a hollow rectangular parallelepiped structure. This solution maximizes the internal volume of the box 31 and provides sufficient buoyancy within a limited space. The rectangular parallelepiped geometry facilitates standardized production and arrangement, reducing manufacturing and construction costs.

[0062] In a specific embodiment, the box body 31 is made of plastic material, such as PVC (polyvinyl chloride), PP (polypropylene), PTFE (polytetrafluoroethylene), PS (polystyrene), PET (polyester), etc.

[0063] In some embodiments, as Figure 2 As shown, the tank 31 is provided with a water inlet 34, which is located on the upper end surface of the tank 31. The inner cavity of the tank 31 and the wave-breaking channel 32 are isolated from each other. Water is injected into the tank 31 through the water inlet 34, so that the top of the wave-breaking tank 3 is higher than the storage space at the normal water level. This design adjusts the weight of the wave-breaking tank 3 by injecting water through the water inlet 34, ensuring that the top of the wave-breaking tank 3 is exposed above the storage space at the normal water level, so that the wave-breaking channel 32 is aligned with the wave surface and ensures the wave-breaking effect. The normal water level is the elevation value determined by long-term water level observation. In one or more years, the water level is equal to or exceeds this elevation value 50% of the time.

[0064] By injecting water to adjust the weight of the wave-breaking water tank 3, the tank body 31 is lifted to form a buffer structure to disperse wave energy and protect terrestrial landscape plants from direct erosion; different water injection amounts can change the ratio of water and gas in the tank body 31. When waves hit, the water and gas in the tank body 31 jointly absorb the impact energy. Among them, since gas has better compressibility, a larger proportion of gas in the tank body 31 can allow gas to enter and exit the water injection port 34 when waves hit.

[0065] In some embodiments, as Figure 2 As shown, a connecting buckle 33 component is provided on the box body 31, and multiple wave-breaking water tanks 3 are arranged in series through the connecting buckle 33 component.

[0066] Specifically, if Figure 3As shown, the connecting buckle 33 assembly includes a first plug buckle 331, a second plug buckle 332, a first plug slot 333 and a second plug slot 334. The first plug buckle 331 and the first plug slot 333 are arranged on both sides of the upper end of the box body 31, and the second plug buckle 332 and the second plug slot 334 are arranged on both sides of the lower end of the box body 31. The first plug buckle 331 and the second plug slot 334 are arranged on the same side of the box body 31 along the length direction of the accommodating space, and the second plug buckle 332 and the first plug slot 333 are arranged on the other same side of the box body 31 along the length direction of the accommodating space; the upper ends of any two adjacent wave-breaking water tanks 3 are connected through the corresponding first plug buckle 331 with the first plug slot 333, the corresponding second plug buckle 332 and the second plug slot 334, so that all wave-breaking water tanks 3 are arranged continuously along the extension direction of the river channel 1.

[0067] This solution connects multiple arranged wave-breaking water tanks 3 in series into a continuous wave-breaking belt through the connecting buckle 33 component, which plays an overall coordinated wave-breaking effect and avoids the wave-breaking blind area caused by the offset of a single box; the installation can be completed by plugging the plug-in buckle into the plug-in groove. This plug-in buckle design realizes modular installation and adjustment and replacement, and its quick assembly reduces construction time.

[0068] In some embodiments, on a single housing 31, the first latch 331 and second latch slot 334 are vertically staggered, while the second latch 332 and first latch slot 333 are vertically staggered. This staggered arrangement of the latches 33 can resist multi-directional wave impacts, preventing disengagement or twisting between housings 31, and facilitating assembly.

[0069] In the above description, the bottom of the box body 31 can be connected to the accommodating space by a rope. When the water level of the river channel 1 is high, the bottom of the wave-breaking water tank 3 maintains a safe distance from the top of the revetment retaining wall 2 and does not leave the accommodating space.

[0070] The wave-breaking structure provided in this embodiment has a wave-breaking water tank 3 that can change with the water level. When the water level of the river channel 1 rises, the wave-breaking water tank 3 rises synchronously due to buoyancy, greatly weakening the impact of ship waves on the landscape plants on the river channel and land, thereby protecting the growth environment of the plants; when the water level drops, the wave-breaking water tank 3 drops synchronously, opening the view of the river channel water surface 11 and the land, thereby improving the viewing effect; at the same time, the wave-breaking channel 32 provided in the wave-breaking water tank 3 enables the water body between the water area of ​​the river channel 1 and the land to be exchanged, thereby enhancing the overall connection of the ecosystem; this application can improve the landscape and ecology of the river channel 1.

[0071] According to an embodiment of the present invention, on the other hand, Figure 1 As shown, a revetment is also provided, comprising a river land 4 and the above-mentioned wave-breaking structure. The wave-breaking structure comprises a wave-breaking water tank 3 having a wave-breaking channel 32, which is used to connect the river 1 and the landscape plant area 42 of the river land 4.

[0072] The revetment utilizes a wave-breaking channel 32 to connect the river waters with the terrestrial landscape plant area 42, forming an ecological channel and resolving the problem of the compatibility between traditional revetments and landscapes. The floating wave-breaking water tank 3 can adapt to water level changes at all times, reducing the continuous scouring of the bank slope by ship waves. The modular design helps reduce maintenance costs and extend the life of the revetment.

[0073] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention. Such modifications and variations are all within the scope defined by the appended claims.
