Description

A coastal inner bay water-facing structure Technical Field

[0001] This application relates to the field of ecological transformation technology of seawalls, specifically to a coastal inner bay waterfront structure. Background Technology

[0002] Seawalls are a crucial component of coastal infrastructure projects. Ecological seawalls, as a new model of coastal protection, meet the requirements of marine disaster prevention, simulate the structure and ecological processes of coastal ecosystems, and possess functions such as resisting storm surges, preventing wave erosion, preventing soil erosion, maintaining biodiversity, and improving water quality. Most seawalls in related technologies are constructed of reinforced concrete, which not only have limited functions but also fail to provide ecological space for marine life. Some more complex seawalls, while achieving protective effects, also have the function of generating electricity from seawater tides; however, during operation, they are susceptible to marine debris and fishing activities, and fish may inadvertently enter the system's operating area and be injured, thus their function in protecting and restoring marine life is not significant. Summary of the Invention

[0003] The first aspect of this application provides a coastal inner bay waterfront structure that can provide habitat and refuge space for fish and other coastal aquatic organisms, which is conducive to improving the protection and recovery of marine life.

[0004] The first aspect of this application provides a coastal inner bay water-facing structure comprising: a seawall, wherein the seawall has a plurality of protrusions on one side of the water-facing surface, the length direction of the protrusions extends at least partially along the height direction of the seawall, the plurality of protrusions are spaced apart along the length direction of the seawall, and a groove recessed into the protrusion is formed between two adjacent protrusions.

[0005] The first trough is located on the water-facing side of the seawall near the bottom, and the top of the first trough has an opening.

[0006] A grating component, comprising a first grating and at least two second gratings, wherein the first grating extends along the length of the seawall and is disposed between a plurality of the protrusions, and a predetermined gap exists between the first grating and the inner wall of the groove; the second gratings extend along the thickness of the seawall and are disposed on both sides of the first grating.

[0007] In addition, the coastal inner bay waterfront structure provided in this application may also have the following additional technical features:

[0008] In one alternative embodiment, the coastal inner bay water-facing structure further includes an ecological net and fasteners. The ecological net is disposed between at least a portion of the first grid and the groove, and the fasteners are used to secure the ecological net to the inner side of the first grid. Gravel is filled between the ecological net and the groove.

[0009] In one alternative embodiment, the second grid includes a cantilever support and a plurality of cylindrical crossbars, one end of which is connected to the sidewall of the protrusion and the other end is connected to the cantilever support. The plurality of cylindrical crossbars are arranged at intervals along the height direction of the seawall. The first trough is located between two adjacent second grids.

[0010] In one alternative embodiment, the first trough includes a bottom plate, a top plate, and side plates. The bottom plate is disposed on the bottom side of the water-facing side of the seawall. The top plate is arranged opposite to the bottom plate and has a notch groove forming an opening at the top of the first trough. The side plates are disposed on the side of the top plate and the side plate away from the seawall.

[0011] In one alternative embodiment, the first trough is filled with a soil layer planted with salt-tolerant and water-resistant plants; and multiple hemp ropes are tied to the first grid and / or the second grid.

[0012] The second aspect of this application provides a construction method for constructing the water-facing structure of the coastal inner bay provided in the first aspect. The construction method includes the following steps:

[0016] 4) Plant plants in the first tank according to environmental parameters such as salinity, tide level and planting elevation. The plants planted should preferably be native mangrove species that are adapted to the ecological restoration area. Tie hemp ropes with shellfish seedlings to the first grid and / or the second grid, with the other end of the hemp ropes extending below the water level, to form a shellfish and algae ecosystem through the ropes below the normal water level.

[0033] As shown in Figures 1-4, the first aspect of this application provides a coastal inner bay waterfront structure, which mainly includes a seawall 1, a first channel 2, and a grid member. The seawall 1 can be a sheet pile-like structure. Multiple protrusions 11 are provided on one side of the waterfront of the seawall 1. The length direction of the protrusions 11 extends at least partially along the height direction of the seawall 1. The multiple protrusions 11 are spaced apart along the length direction of the seawall 1, and a groove 12 is formed between adjacent protrusions 11. The first channel 2 is located on the waterfront side of the seawall 1 near the bottom, and an opening is provided at the top of the first channel 2. The grid member includes a first grid 3 and at least two second grids 4. The first grid 3 extends along the length direction of the seawall 1 and is disposed between the multiple protrusions 11, and a predetermined gap exists between the first grid 3 and the inner wall of the groove 12. The second grids 4 extend along the thickness direction of the seawall 1 and are disposed on both sides of the first grid 3.

[0034] In this embodiment, the coastal inner bay water-facing structure, through the arrangement of a first grid 3 along the length of the seawall 1, a second grid 4 along the thickness of the seawall 1, and other structures on the water-facing side of the seawall 1, not only serves to dissipate wave energy and reduce waves, but also provides a suitable habitat and protection environment for marine life such as fish, improving water exchange performance. At the same time, the space within the first trough 2 can be used for planting, effectively increasing coastal biodiversity and contributing to the protection and restoration of marine life. Furthermore, by establishing different shallow water environments, the ecological and scenic features of the seawall and the accessibility for tourists to the water can be enhanced.

[0035] As shown in Figures 1-2 and 4, in one specific embodiment, the coastal inner bay water-facing structure further includes an ecological net 5 and fasteners. The ecological net 5 is disposed between at least a portion of the first grid 3 and the groove 12. The fasteners are used to fix the ecological net 5 to the inner side of the first grid 3. Gravel is filled between the ecological net 5 and the groove 12, which can provide habitat for marine life and promote biodiversity. At the same time, the silt carried by the tide is gradually deposited into the first trough 2 through the gravel, which helps the plants in the first trough 2 to grow.

[0036] As shown in Figures 1-3, in one specific embodiment, the second grid 4 includes a cantilever support 41 and multiple cylindrical crossbars 42. One end of each cylindrical crossbar 42 is connected to the side wall of the protrusion 11, and the other end is connected to the cantilever support 41. The multiple cylindrical crossbars 42 are arranged at intervals along the height of the seawall 1. The first trough 2 is located between two adjacent second grids 4. In addition, the first grid 3 is composed of multiple grid crossbars 31 arranged at intervals. The structure of the grid crossbars 31 can be the same as that of the cylindrical crossbars 42, which will not be elaborated here.

[0037] As shown in Figures 1-2 and 4, in one specific embodiment, the first trough 2 includes a bottom plate 21, a top plate 22, and a side plate 23. The bottom plate 21 is disposed on the bottom side of the water-facing side of the seawall 1. The top plate 22 is arranged opposite to the bottom plate 21, and the top plate 22 has a notch and forms an opening at the top of the first trough 2. The side plate 23 is disposed on the side of the top plate 22 and the side plate 23 away from the seawall 1.

[0038] Specifically, the base plate 21 and top plate 22 are preferably rectangular plate structures with curved sides. The curves on both sides of the base plate 21 match the bottom edges of the cantilever supports 41 on both sides. One long side of the top plate 22 has a rectangular hollow structure, while the center of the structure formed by the other long side and the short sides on both sides has a hollow structure. Alternatively, the side plate 23 can also be a rectangular plate structure with a width matching the hollow structure. The side plate 23, base plate 21, and top plate 22 together form the first trough 2 for plant growth. In addition, the first trough 2 is filled with a soil layer planted with mangrove species that have wave-proofing and soil-stabilizing functions, are salt-tolerant and flood-resistant. The specific length and size of the plants can be varied according to the project requirements. Furthermore, multiple hemp ropes are tied to the first grid 3 and / or the second grid 4. Underwater hemp ropes are used to cultivate shellfish, such as mussels. As the mussels grow, they form clusters of mussel organisms.

[0039] The second aspect of this application provides a construction method for constructing the coastal inner bay waterfront structure provided in the first aspect embodiment. This construction method mainly includes the following steps:

[0040] 1) Drill holes at predetermined positions on the water-facing side of seawall 1. After drilling, install the first grid 3 and the second grid 4. The first grid 3 and the second grid 4 are installed into the corresponding holes by interference fit.

[0041] 2) Install an ecological net 5 in the space enclosed by the groove 12 of the first grid 3 and the seawall 1. The ecological net 5 is placed close to the first grid 3 from top to bottom. The ecological net 5 is fixed to the side structure of the seawall 1 by fasteners.

[0042] 3) Install the first trench 2, then fill the space between the groove 12 of the seawall 1 and the first grid 3 with gravel and / or crushed stone, and fill the first trench 2 with soil.

[0043] 4) Plant plants in the first tank 2 according to environmental parameters such as salinity, tide level and planting elevation. Priority should be given to native mangrove species that are adapted to the ecological restoration area. Tie hemp ropes with shellfish seedlings to the first grid 3 and / or the second grid 4. The other end of the hemp rope extends below the water level, forming a shellfish and algae ecosystem through the ropes below the normal water level.

[0044] This construction method is used to construct the coastal inner bay waterfront structure provided in the first aspect embodiment. Since the coastal inner bay waterfront structure provided in the first aspect embodiment can increase coastal biodiversity and is conducive to improving the protection and restoration of marine life, the coastal inner bay waterfront structure constructed by this method also has the same effect. Therefore, this article will not elaborate on it in detail.

[0045] In one specific embodiment, in step 1), when drilling holes at the installation positions of the first grid 3, the drilled holes must not penetrate the protrusions 11 of the seawall 1. At least four protrusions 11 are drilled as a group for the installation of the first grid 3. For example, on the water-facing side of the seawall 1, four protrusions 11 are drilled as a group, and there is a groove 12 between every two protrusions 11, resulting in three grooves 12 between every four protrusions 11. At the same height, a set of opposing mounting holes is drilled on each groove 12, one on each of the two sides, resulting in a total of six mounting holes laterally. It is necessary to ensure that the centers of each pair of opposing mounting holes are on the same horizontal line, and the six mounting holes are considered as a group. The depth of the holes should not be too deep, and the vertical distance between the bottoms of a pair of opposing holes should not be less than the length of the inserted grid crossbar 31. After drilling is completed, insert a grid crossbar 31 into each set of opposite mounting holes until all through holes have been filled with crossbars. The length of the grid crossbar 31 should be slightly larger than the distance between the openings of the two opposite holes. It is installed into the opposite holes using an interference fit method.

[0046] In one specific embodiment, in step 1), when drilling the installation position of the second grid 4, the drilling is performed at a preset position of the protrusion 11 of the seawall 1. The drilling depth must ensure that the cylindrical crossbar 42 of the second grid 4 can be firmly fixed in the hole, and the hole diameter is slightly larger than the diameter of the cylindrical crossbar 42. After drilling is completed, the cylindrical crossbar 42 of the second grid 4 is hammered into the corresponding hole using an interference fit installation method.

[0047] Additionally, during the installation of the first groove 2 in step 3), its bottom plate 21 is supported on the left and right ends of the lowest cylindrical crossbar 42 of the second grille 4; then, the top plate 22 is supported on the higher-positioned second grille 4; finally, the side plate 23 is supported on the bottom plate 21 through the positioning holes left on the top plate 22 from top to bottom. The installation position of the top plate 22 can be adjusted according to the height of the second grille 4.

[0048] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
