Ecological revetment structure suitable for restricted waterways

Abstract

This invention discloses an ecological revetment structure suitable for restricted waterways, comprising guide rail brackets and a porous permeable structure. Several guide rail brackets are arranged along the waterway direction and fixedly connected to the bank slope. The porous permeable structure is mounted between two adjacent guide rail brackets and can slide relative to each other in the vertical direction. Inside the porous permeable structure, symmetrically arranged energy dissipation channels are set along the main direction of the ship's traveling waves. Each energy dissipation channel includes a straight section and an arc-shaped turning section. Two arc-shaped turning sections are connected to form a high-curvature arc-shaped flow guiding structure, and the two energy dissipation channels are also connected. The porous permeable structure of this invention can slide vertically with changes in the water level of the waterway, thereby reducing the concentration of stress on the structure. By setting bidirectional energy dissipation channels inside the porous permeable structure, the ship's traveling waves generate countercurrent, bypass flow, and multi-stage turning flow after entering the revetment structure, achieving multi-stage energy dissipation, thereby significantly reducing the scouring effect of the ship's traveling waves on the bank slope.

Description

Technical Field

[0001] This invention relates to the field of road transportation technology, and in particular to an ecological revetment structure suitable for restricted waterways, which can be directly applied to the green maintenance of canal waterway revetments. Background Technology

[0002] Guided by the concept of sustainable transportation systems, ecological revetment structures have been widely used in inland waterway protection projects. Existing ecological revetment structures mostly utilize precast concrete materials and various types of permeable structures (including modular and prefabricated types), laying the foundation for revetment vegetation planting and ecological restoration.

[0003] However, existing ecological revetment structures generally suffer from the following drawbacks: First, they have high construction costs and complex construction processes; second, most current ecological revetment structures are integrated designs, and once they are built and put into use or suffer partial damage, their maintenance and repair become extremely difficult. It is difficult to carry out effective dynamic adjustments and local repairs, and they cannot adapt to dynamically changing hydrological and meteorological conditions and external influencing factors such as navigational traffic flow. Furthermore, they are prone to inducing water traffic safety accidents and endangering the safety of ship navigation.

[0004] Furthermore, due to the limited cross-sectional dimensions and navigation conditions of restricted waterways such as canals, traditional sloping ecological revetments are poorly suited for such waterways. Therefore, their revetment structures mostly adopt vertical or near-vertical arrangements. Meanwhile, the ship waves generated during navigation are the primary hydrodynamic force borne by the revetment structures in restricted waterways, characterized by frequent, high-disturbance, and energy-concentrated activity. In restricted navigable waters, the water level fluctuations, flow field distribution, and wave height spectrum characteristics significantly differ from those of natural rivers, placing higher demands on the erosion resistance and energy dissipation capabilities of the revetment structures.

[0005] Due to the limited cross-sectional dimensions and navigation conditions of restricted waterways such as canals, traditional sloping ecological revetments are poorly suited for these waterways. Therefore, their revetment structures are mostly arranged in a vertical or near-vertical configuration. Furthermore, the ship waves generated during navigation are the primary hydrodynamic force borne by the revetment structures in restricted waterways, characterized by frequent, high-disturbance, and energy-concentrated activity. Consequently, restricted waterways such as canals place higher demands on the scour resistance and energy dissipation capabilities of the revetment structures. Traditional ecological revetment structures are therefore less suitable for revetment projects in restricted waterways such as canals. Summary of the Invention

[0006] To address the problems of strong scouring of riverbank revetment structures by ship waves in restricted waterways, complex hydrodynamic effects, and insufficient energy dissipation capacity of traditional revetment structures, this invention provides an ecological revetment structure suitable for restricted waterways. It utilizes a vertically sliding, mounted, porous, permeable structure to adapt to changes in water level. Furthermore, the internal bidirectional energy dissipation channels of the porous, permeable structure enable multi-stage dissipation of ship wave energy, while also providing ecological restoration functions, thereby improving the stability and durability of the waterway revetment structure.

[0007] The technical solution adopted in this invention is: An ecological revetment structure suitable for restricted waterways includes guide rail brackets and a porous permeable structure; several guide rail brackets are arranged along the waterway direction and fixedly connected to the bank slope; the porous permeable structure is mounted between two adjacent guide rail brackets and can slide relative to each other along the vertical direction of the guide rail brackets; the porous permeable structure has symmetrically arranged energy dissipation channels inside along the main direction of the ship's traveling waves, each energy dissipation channel includes a straight section and an arc-shaped turning section, and the two arc-shaped turning sections are connected to form a large-curvature arc-shaped flow guiding structure, thus connecting the two energy dissipation channels.

[0008] In the above scheme, the rear end of the central solid structure surrounded by the two energy dissipation channels is provided with a concave arc-shaped flow guide surface. The arc-shaped flow guide surface is adapted to the arc-shaped turning section of the two energy dissipation channels and is used to guide the water flow from the energy dissipation channels on both sides to smoothly turn and converge momentum in conjunction with the large curvature arc-shaped flow guide structure.

[0009] In the above scheme, energy dissipation devices are respectively installed in the middle of the two straight channel segments. The front and rear ends of the energy dissipation devices are respectively provided with concave arc-shaped counter-flow surfaces to form a small curvature arc-shaped flow guiding structure, which is used to guide the water flow from the energy dissipation channels on both sides to counter-flow.

[0010] In the above scheme, the inner walls of the energy dissipation channel and the energy dissipation device have a roughened or porous surface structure.

[0011] In the above scheme, the side of the guide rail bracket is provided with a through hole horizontal to the bank slope, and is connected by a crossbar to form a connection structure between adjacent guide rail brackets; the porous permeable structure is provided with a side through hole for the crossbar to pass through, so that the porous permeable structure is hung between adjacent guide rail brackets, and the diameter of the side through hole is larger than the diameter of the crossbar, so that the porous permeable structure can slide relative to the guide rail bracket in the vertical direction.

[0012] In the above scheme, the side through holes of the porous permeable structure are perpendicular to the energy dissipation channel and are staggered from each other in the vertical direction.

[0013] In the above scheme, the side of the guide rail bracket is provided with a sliding groove extending in the vertical direction; the left and right ends of the porous permeable structure are respectively provided with sliders adapted to the sliding groove, and the left and right sliders are respectively embedded in the sliding grooves of the adjacent sliding groove guide rail brackets, and can slide in the vertical direction in the sliding groove.

[0014] In the above scheme, the guide rail bracket is provided with a through hole perpendicular to the bank slope; the ecological bank protection structure also includes an anchor rod that passes through the through hole perpendicular to the bank slope, the front end of the anchor rod is fixedly connected to the guide rail bracket, and the rear end of the anchor rod is fixedly connected to the bank slope.

[0015] In the above scheme, the guide rail bracket is provided with a protrusion; the ecological revetment structure also includes a top plate set on the top of the guide rail bracket, the bottom surface of the top plate is provided with a groove structure that matches the protrusion, and the positioning and limiting of the guide rail bracket is achieved by the embedded cooperation of the protrusion and the groove structure; the top surface of the top plate is provided with anchoring holes and is fixed to the bank slope or support structure by anchor rods.

[0016] In the above scheme, the spacing between adjacent guide rail brackets along the waterway direction is determined based on the characteristic wavelength of the ship waves generated by the representative ship type in navigation, which is 0.3 to 0.8 times the characteristic wavelength.

[0017] The beneficial effects of this invention are: 1. The ecological revetment structure of this invention utilizes a vertically sliding, multi-porous permeable structure mounted on a guide rail bracket. This allows the multi-porous permeable structure to slide vertically with changes in the channel water level, thereby reducing stress concentration and improving the safety and adaptability of the ecological revetment structure. Simultaneously, by incorporating bidirectional energy dissipation channels within the multi-porous permeable structure, ship waves undergo counter-current, bypass, and multi-stage turning flows upon entering the revetment structure, achieving multi-stage energy dissipation and significantly reducing the scouring effect of ship waves on the bank slope.

[0018] 2. The bidirectional energy dissipation channel is also equipped with an energy dissipation device. At both ends of the device, arc-shaped counter-flow surfaces are set to form a small-curvature arc-shaped guide structure, which guides the water flow from both sides of the energy dissipation channel to counter-flow. When the water flow passes through the small-curvature arc-shaped guide structure, its direction changes and local opposing flows are formed, thus achieving primary energy dissipation through momentum counter-flow. After being turned by the small-curvature arc-shaped guide structure, the water flow flows from both sides of the energy dissipation device, forming a flow around the inner wall of the energy dissipation channel, thereby increasing the contact area between the water flow and the porous permeable structure, achieving further friction and shear energy dissipation. Near the rear end of the energy dissipation channel, a large-curvature arc-shaped guide structure is set, causing the water flow from the left and right energy dissipation channels to turn again and converge in opposite directions. Through momentum cancellation, deep dissipation of the ship's wave energy is achieved, causing the ship's wave to gradually attenuate as it passes through the revetment structure.

[0019] 3. This invention, through its porous permeable structure and roughened channel surface, can promote sediment deposition and aquatic organism attachment, thereby improving the ecological environment of the waterway bank protection while exerting its energy dissipation function.

[0020] 4. When a local module is damaged, or when it is necessary to clean and replenish the ecological medium, the corresponding porous permeable structure can be lifted above the water surface along the guide rail bracket to complete the replacement or maintenance. The whole process does not require cofferdam construction or large-scale occupation of the waterway, reducing the impact of revetment structure maintenance on normal ship navigation.

[0021] 5. This invention can improve the energy dissipation effect of the overall bank protection system by reasonably setting the spacing of the guide rail brackets so that the energy of the ship's waves gradually decreases along the direction of the waterway.

[0022] In summary, this invention, by leveraging the advantages of a mounted porous permeable structure, can not only meet the personalized bank protection needs of different river sections and navigation conditions, but also achieve differentiated maintenance goals such as rapid local bank repair and dynamic adjustment, which is of great value for promoting the green and sustainable development of inland waterway transportation.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0027] It should be noted that the illustrations provided in the embodiments of the present invention are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0028] In this invention, it should also be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used only for descriptive and distinguishing purposes and should not be construed as indicating or implying relative importance.

[0029] Furthermore, it should be noted that the features of the various embodiments of the present invention can be combined or integrated in whole or in part, and as those skilled in the art will understand, they can interact and operate in different ways. Each embodiment can be implemented independently of each other or in association with one another.

[0030] like Figure 1As shown, this invention proposes an ecological revetment structure suitable for restricted waterways, comprising guide rail brackets 1 and a porous permeable structure 2. Several guide rail brackets 1 are arranged along the waterway direction and fixedly connected to the bank slope, serving as guiding components for the porous permeable structure 2. The porous permeable structure 2 is mounted between adjacent guide rail brackets 1, thus forming an integrated revetment structure system. The porous permeable structure 2 can slide relative to the guide rail brackets 1 in the vertical direction, thereby adapting to changes in water level or ship wave forces at different times in the waterway. Figure 2 As shown, the porous permeable structure 2 has symmetrically arranged energy dissipation channels 21 inside along the main direction of the ship's waves. Each energy dissipation channel 21 includes a straight section and an arc-shaped turning section. The two arc-shaped turning sections are connected to form a large curvature arc-shaped flow guiding structure 211, and the two energy dissipation channels 21 are connected.

[0031] In this embodiment, the central solid structure 24 surrounded by the two energy dissipation channels 21 is provided with a concave arc-shaped flow guide surface 241 at its rear end. The arc-shaped flow guide surface 241 is adapted to the arc-shaped turning section of the two energy dissipation channels 21, and is used to guide the water flow from the energy dissipation channels 21 on both sides to smoothly turn and merge momentum, thereby enhancing the counter-current energy dissipation effect.

[0032] In a further optimization, in this embodiment, energy dissipation devices 23 are respectively installed at the middle positions of the two straight channel segments to dissipate the energy of the water flowing into the energy dissipation channel 21. Arc-shaped counter-flow surfaces are respectively provided at the front and rear ends of the energy dissipation device 23 to form a small-curvature arc-shaped flow guide structure 231, which is used to guide the water flow from the energy dissipation channels 21 on both sides to counter-flow.

[0033] When the water flow passes through the small-curvature arc-shaped guide structure 231, its direction changes and a local opposing flow is formed, thereby achieving primary energy dissipation through momentum counteraction. After being turned by the small-curvature arc-shaped guide structure 231, the water flow flows from both sides of the energy dissipation device 23 and forms a flow around the inner wall of the energy dissipation channel 21, thereby increasing the contact area between the water flow and the porous permeable structure 2, achieving further friction and shear energy dissipation. The energy dissipation channel 21 is provided with a large-curvature arc-shaped guide structure 211 near the rear end, which, together with the concave arc-shaped guide surface 241 at the rear end of the central solid structure 24, causes the water flow from the energy dissipation channels 21 on the left and right sides to turn again and form an opposing convergence. Through momentum cancellation, the deep dissipation of the ship's wave energy is achieved, causing the ship's wave to gradually attenuate as it passes through the revetment structure. Under the thrust and suction of the ship's waves, the energy dissipation device 23 and the arc-shaped flow guide structure can induce the water flow to form multi-stage turning, counter-current flow and flow around the flow path, so that the porous permeable structure 2 has a significant energy dissipation effect under the positive thrust and reverse suction of the ship's waves.

[0034] It should be noted that the "left and right" direction mentioned in the orientation of this invention is along the waterway, and the "front and back" direction is perpendicular to the waterway.

[0035] In this embodiment, the inner walls of the energy dissipation channel 21 and the energy dissipation device 23 are roughened or have a porous surface structure to promote the retention and deposition of sediment in the water and the attachment of aquatic organisms, thereby forming a stable ecological habitat while dissipating energy.

[0036] In a further optimization, this embodiment features a horizontal through-hole 12 on the side of the guide rail bracket 1, connected by a crossbar 4, forming a connection structure between adjacent guide rail brackets 1. The porous permeable structure 2 has a side through-hole 22 for the crossbar 4 to pass through, allowing the porous permeable structure 2 to be mounted between adjacent guide rail brackets 1, forming a stable overall revetment structure system. The diameter of the side through-hole 22 is larger than the diameter of the crossbar 4, enabling the porous permeable structure 2 to slide relative to the guide rail bracket 1 in the vertical direction. The structure of the crossbar 4 is as follows... Figure 5 As shown, it has external threads at both ends and is fixedly connected to the guide rail bracket 1 by nuts.

[0037] In a further optimization, in this embodiment, the side through hole 22 is perpendicular to the energy dissipation channel 21 and is staggered from each other in the vertical direction.

[0038] It should be noted that the mounting method in this invention is not limited to the above-described scheme. In another embodiment of this invention, the side of the guide rail bracket 1 is provided with a sliding groove extending in the vertical direction; the left and right ends of the porous permeable structure 2 are respectively provided with sliders adapted to the sliding groove, and the left and right sliders are respectively embedded in the sliding grooves of the adjacent guide rail bracket 1, and can slide in the vertical direction within the sliding groove.

[0039] In a further optimization, this embodiment includes a through hole 11 perpendicular to the bank slope on the guide rail bracket 1. The ecological revetment structure also includes an anchor rod 5 penetrating the through hole 11 perpendicular to the bank slope. The front end of the anchor rod 5 is fixedly connected to the guide rail bracket 1, and the rear end of the anchor rod 5 is fixedly connected to the bank slope. The structure of the anchor rod 5 is as follows: Figure 6 As shown, the front end of the anchor rod 5 is provided with an external thread, which is fixedly connected to the guide rail bracket 1 by a nut; the rear end of the anchor rod 5 is tapered to facilitate passing through the through hole 11 perpendicular to the bank slope. In addition, there are two horizontal bar through holes 51 at the tail of the anchor rod 5, which are aligned with the through hole 12 horizontal to the bank slope, for the horizontal bar 4 to pass through, so as to realize the structural connection between the guide rail brackets 1.

[0040] In a further optimization, this embodiment includes a protrusion 13 on the guide rail bracket 1. The ecological revetment structure also includes a top plate 3 disposed on top of the guide rail bracket 1. The bottom surface of the top plate 3 has a groove structure that matches the protrusion 13. The positioning and limiting of the guide rail bracket 1 are achieved through the embedded cooperation between the protrusion 13 and the groove structure. Anchoring holes are provided on the top surface of the top plate 3, and it is fixedly connected to the bank slope or support structure via anchor rods 5 to ensure the overall stability of the revetment structure.

[0041] Further optimization is achieved in this embodiment, where the channel width, channel length, and radius of curvature of the arc-shaped turning section of the energy dissipation channel 21 are determined based on the characteristic parameters of the ship waves generated by representative ship types in the canal. These ship wave characteristic parameters include characteristic wave height, characteristic wave period, and near-shore oscillating velocity. Specifically, with the goal of increasing wave energy attenuation, the optimal channel width, channel length, and radius of curvature of the arc-shaped turning section are determined using a fitting function, in conjunction with the ship wave characteristic parameters. The terms "large curvature" and "small curvature" in the large-curvature arc-shaped guide structure 211 and the small-curvature arc-shaped guide structure 231 are relative concepts; the specific radius of curvature is determined to be optimal through a fitting function.

[0042] In a further optimization, in this embodiment, the spacing between adjacent guide rail brackets 1 along the waterway direction is determined based on the characteristic wavelength of the ship waves generated by representative navigation vessel types, and is 0.3 to 0.8 times the characteristic wavelength. This ensures that when the ship waves are incident on the revetment structure perpendicular to the waterway direction, the pushing and suction effects of adjacent revetment structures on the same ship waves are staggered in time. This allows the ship wave energy to be dissipated in segments through multiple revetment structures along the shoreline, preventing adjacent revetment structures from experiencing the same hydrodynamic extreme value at the same time.

[0043] In this embodiment, the guide rail bracket 1 is further optimized by adopting a porous concrete pile structure.

[0044] Under normal navigation conditions, the ecological revetment structure enters its working state. The water flow generated by navigating vessels enters the energy dissipation channel 21 through the surface of the porous permeable structure 2, where energy is dispersed and dissipated, significantly reducing the wave pressure acting on the ecological revetment structure.

[0045] When a local module is damaged, or when it is necessary to clean and replenish the ecological medium, the corresponding porous permeable structure 2 can be lifted above the water surface along the guide rail bracket 1 to complete the replacement or maintenance. The whole process does not require cofferdam construction or large-scale occupation of the waterway, reducing the impact of revetment structure maintenance on normal ship navigation.

[0046] It should be noted that, depending on the implementation needs, the various steps / components described in this application can be broken down into more steps / components, or two or more steps / components or parts of the operation of steps / components can be combined into new steps / components to achieve the purpose of this invention.

[0047] The order of the steps in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0048] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
