Description

Technical Field

[0001] This invention relates to the field of water environment engineering technology, specifically to a ring-shaped columnar artificial reef and a method for constructing a coastal ecological field. Background Technology

[0002] The coastal zone is a complex and intersecting geographical unit connecting the marine and terrestrial systems. It is not only one of the most active natural regions on Earth but also one with the most favorable resource and environmental conditions. It is an independent environmental system characterized by the interaction of coastal dynamics and the coastal land, exhibiting transitional features between the sea and land, and is most closely related to human survival and development. With the rapid increase in population and the accelerating pace of urbanization, the coastal zone is facing enormous pressures from global climate change, sea-level rise, regional ecological damage, biodiversity loss, increased pollution, and degradation of fishery resources, seriously affecting its sustainable development.

[0003] Currently, most traditional coastal zone restoration methods involve using natural rocks or artificial reefs to rebuild tidal flat habitats and protect tidal flat biodiversity. However, since artificial reefs are point-based structures, they are difficult to achieve large-scale restoration effects on the coastal zone. Furthermore, deploying individual artificial reefs over a large area would require substantial investment. Additionally, when the coastal zone is muddy, artificial reefs made with concrete frames are heavy and easily sink into the silt, leaving little substrate for fish and aquatic life, thus hindering their ability to fulfill their intended functions. Summary of the Invention

[0004] In view of this, the present invention provides a ring-shaped artificial reef ring and a method for constructing a coastal ecological field, in order to solve the problems in the prior art where the point-based arrangement of artificial reefs is difficult to form a large-scale coastal zone management, and individual artificial reefs are easy to sink into silt and cannot play a role.

[0005] In a first aspect, the present invention provides an annular columnar artificial reef ring, comprising composite piles, first connectors and connecting beams. Multiple composite piles are vertically arranged in the mudflats and are arranged circumferentially. Multiple first connectors are correspondingly arranged on the composite piles. Multiple connecting beams are arranged side by side, and the two ends of the connecting beams are respectively connected to the first connectors on the adjacent composite piles. The connecting beams and the composite piles form an annular closed structure.

[0006] Beneficial effects: In this invention, the annular columnar artificial reef ring is formed into a closed annular structure. When the combined piles are set in the mudflat, the connecting beams between the combined piles can play a supporting role on the mudflat, preventing the combined piles from sinking too deep and causing the entire annular columnar artificial reef ring to sink into the mudflat silt. The enclosed annular structure becomes a habitat for marine organisms, which is conducive to maintaining the stability of the coastal ecological environment. The vertically set combined piles can realize the flow velocity of the shallow water area, cut off the surface gullies, prevent further erosion of the surface, stabilize the surface, and construct a shallow water environment that is easy to silt up, thus creating conditions for the formation of the ecological base structure.

[0007] In one alternative embodiment, the connecting beam and the composite piles enclose at least two annular closed structures, with at least one annular closed structure located within one of the annular closed structures.

[0008] Beneficial effects: For tidal flats with many gullies or severe erosion, the present invention adopts a double-layered ring-shaped closed structure, which can regulate the flow velocity in the shallow tidal flat area, cut off the gullies on the tidal flat surface, prevent further erosion of the tidal flat surface, stabilize the tidal flat surface, and create a shallow tidal flat environment that is easy to silt up, thus creating conditions for the formation of ecological substrate structure.

[0009] In one alternative embodiment, the composite pile includes a pile foundation, a second connector, and a connecting rod. At least three pile foundations are vertically arranged in the mudflats, multiple second connectors are correspondingly arranged on the pile foundations, and the two ends of multiple connecting rods are respectively connected to the second connectors on adjacent pile foundations. The connecting rods and the pile foundations form a polygonal structure.

[0010] Beneficial effects: The composite piles in this invention adopt a frame composed of at least three pile foundations with an open structure. When waves pass over the pile foundations, they have a wave-dissipating effect, resulting in smaller waves in the waters enclosed by the annular column reef ring. This reduces the interference of hydrodynamic forces such as tides and waves, prevents the loss of sediment in the waters, and allows for the accumulation of more nutrients.

[0011] In one alternative implementation, the number of piles is three, and the three piles are respectively arranged at the vertices of an equilateral triangle.

[0012] Beneficial effects: The present invention arranges the three pile foundations into an equilateral triangle structure, which can make the composite piles have better stability.

[0013] In one alternative implementation, the pile foundation has a tapered pile head at its bottom.

[0014] Beneficial effects: The present invention provides a conical pile head at the bottom of the pile foundation, which facilitates the installation of the pile foundation in the tidal flat during construction.

[0015] In one alternative embodiment, the conical pile head is provided with a filler.

[0016] Beneficial effects: The present invention sets a filling element inside the conical pile head, which increases the weight of the conical pile head and causes the overall center of gravity of the pile foundation to shift downward, thereby ensuring the stability of the pile foundation.

[0017] In one alternative embodiment, the first connector includes a first mounting portion and a first connecting portion. The first mounting portion is mounted on the composite pile, and the first connecting portion is disposed on the first mounting portion and connected to the connecting beam.

[0018] Beneficial effects: In this invention, first connecting parts are respectively provided on both sides of the first mounting part, which facilitates the connection of the connecting beam to two adjacent composite piles. It has the advantages of simple structure and convenient installation.

[0019] In one alternative embodiment, the second connector includes a second mounting portion and a second connecting portion. The second mounting portion is mounted on the pile foundation, and two second connecting portions are disposed on both sides of the second mounting portion. The second connecting portions are connected to the connecting rod.

[0020] Beneficial effects: In this invention, second connecting parts are respectively provided on both sides of the second mounting part, which facilitates the connection of the connecting rod to two adjacent pile foundations. It has the advantages of simple structure and convenient installation.

[0021] In one alternative embodiment, the annular column reef ring also includes a hanging net, which is vertically and detachably installed on adjacent connecting beams.

[0022] Beneficial effects: The netting in this invention provides space for aquatic microorganisms to attach, grow, and reproduce. The increased microorganisms further promote the degradation of pollutants in the water, thus creating a virtuous cycle and achieving good ecological and environmental protection effects. Simultaneously, placing the netting on the receding water side also helps to intercept sediment or reduce the erosion of the mudflats by tides and waves.

[0023] In one alternative implementation, the composite piles, connecting beams, and wire mesh are made of biodegradable materials.

[0024] Beneficial effects: The composite piles, connecting beams and hanging nets in this invention are made of biodegradable materials, which can effectively reduce the degree of environmental pollution and reduce the residue of waste in the coastal environment.

[0025] In one alternative embodiment, the biodegradable material is moso bamboo.

[0026] Beneficial Effects: This invention uses bamboo as a biodegradable material, which has good biocompatibility, is suitable for aquatic organisms to inhabit, and is easy for algae and other aquatic organisms to attach and grow, forming a food ground. Bamboo material has a rough surface, a large specific surface area, abundant raw material resources, and is a natural material, possessing advantages such as low cost, renewability, low environmental pollution, and easy degradation. The surface of bamboo material has a high content of phospholipids and dehydrogenase activity of attached microorganisms, providing space for microbial attachment, growth, and reproduction, and continuously promoting the degradation of pollutants in the water.

[0027] Secondly, the present invention also provides a method for constructing a coastal ecological field, using the aforementioned annular cylindrical artificial reef ring, the construction method comprising:

[0028] Acquire sites in coastal zones requiring restoration;

[0029] Obtain the installation location of each annular columnar artificial reef ring in the mudflats;

[0030] In the installation position, the pile foundation, the second connector and the connecting rod are assembled into a composite pile in sequence;

[0031] Then, assemble each composite pile with the first connecting piece and the connecting beam to form a ring-shaped column reef ring;

[0032] Multiple annular columnar artificial reefs form an ecological field at the coastal zone site to be restored.

[0033] Beneficial effects: In this invention, multiple adjacent annular columnar artificial reef rings form an annular artificial reef group. Each annular columnar artificial reef ring encloses a body of water into multiple enclosed rings, forming annular ecological fields. The enclosed rings are both artificial reef groups and can also control coastal erosion. The two functions are combined into one, constructing a complete and healthy tidal flat ecosystem.

[0059] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0060] In related technologies, traditional coastal zone restoration mostly involves placing artificial reefs in the coastal zone. However, some coastal zones are muddy with thick silt on the bay surface, which is not conducive to the placement of traditional artificial reefs, and the effect of scattered artificial reefs is limited.

[0061] Traditional artificial reef materials are mostly made of "cold" materials such as concrete and plastic, which lack affinity. Fish and aquatic organisms need to adapt to them before the reefs can become their habitat. Because these reefs are heavy, they are prone to sinking into the silt, leaving very little substrate for fish and aquatic organisms, thus greatly reducing the function of the artificial reef.

[0062] Traditional scattered artificial reef formations can exacerbate beach erosion and create new gullies if the reefs are not properly arranged.

[0063] Traditional artificial reefs are arranged in an adjacent manner. Although they form a group of artificial reefs, they are still just a large point structure on a large mudflat and do not have the effect of area management.

[0064] The following is combined with Figures 1 to 16 The following describes embodiments of the present invention.

[0065] According to an embodiment of the present invention, in one aspect, such as Figures 1 to 14A ring-shaped artificial reef ring 100 is provided, including composite piles 1, first connectors 2 and connecting beams 3. Multiple composite piles 1 are vertically set in the mudflats and arranged circumferentially. Multiple first connectors 2 are correspondingly set on the composite piles 1. Multiple connecting beams 3 are arranged side by side. The two ends of the connecting beams 3 are respectively connected to the first connectors 2 on the adjacent composite piles 1. The connecting beams 3 and the composite piles 1 form a ring-shaped closed structure.

[0066] Specifically, in this embodiment, the annular columnar artificial reef ring 100 is applied in the tidal flats of the coastal zone. This embodiment does not specifically limit the tidal flats. In order to conform to the actual situation, the tidal flats in this embodiment are soft soil tidal flats with uneven settlement of soft soil foundation.

[0067] In this embodiment, as Figure 1 and Figure 4 As shown, several composite piles 1 are vertically set, with the bottom of the composite piles 1 inserted into the mudflats. The composite piles 1 are arranged circumferentially, and several connecting beams 3 are horizontally connected to two adjacent composite piles 1, thereby enclosing the composite piles 1 into a circular or polygonal enclosure.

[0068] In this embodiment, as Figure 4 As shown, the arrangement of the connecting beam 3 is not specifically limited. To conform to reality, in this embodiment, the connecting beam 3 is arranged in two layers. Specifically, one layer of connecting beam 3 is set at the design tide level of the composite pile 1, and another layer is set at the highest tide level. In other embodiments, depending on the height of the composite pile 1 and the geological conditions of the tidal flat, the connecting beam 3 can also be set in other numbers. To ensure the stability of the composite pile 1, the number of layers of connecting beam 3 should not be less than two. When the composite pile 1 sinks to the point where the connecting beam 3 abuts against the surface of the tidal flat, the bottom layer of connecting beam 3 can play a supporting role on the tidal flat, which can prevent the composite pile 1 from sinking too deep, thereby ensuring that the annular columnar artificial reef ring 100 can provide a sufficient substrate for fish and aquatic life activities in the tidal flat.

[0069] In this embodiment, as Figure 1 As shown, several composite piles 1 are arranged at equal intervals on a circular circumference, and adjacent composite piles 1 are connected by connecting beams 3 of equal length to form a circular ecological field 200. In this embodiment, the radius R of the circular central axis of the single-row enclosure should be determined according to the coastal zone to be restored. To conform to the actual situation, the radius R in this embodiment is no greater than 10m.

[0070] In this embodiment, when the number of composite piles 1 is small, the circular ecological field 200 formed by the composite piles 1 and the connecting beam 3 is polygonal. When the number of composite piles 1 is large, the circular ecological field 200 formed by the composite piles 1 and the connecting beam 3 is approximately circular. The resulting circular structure is more rationally stressed and can withstand greater wind and wave impacts.

[0071] In this invention, the composite piles 1 and the connecting beams 3 are arranged to form a circular or polygonal annular columnar artificial reef ring 100. When the composite piles 1 are set in the mudflat, the connecting beams 3 between the composite piles 1 can play a supporting role on the mudflat, preventing the composite piles 1 from sinking too deep and causing the annular columnar artificial reef ring 100 to sink into the mudflat silt. The circular or polygonal structure formed becomes a habitat for marine organisms, which is conducive to maintaining the stability of the coastal ecological environment. The vertically set composite piles 1 can realize the flow velocity of the shallow area, cut off the surface gullies, prevent further erosion of the surface, stabilize the surface, and construct a shallow environment that is easy to silt up, creating conditions for the formation of ecological base structure.

[0072] In one embodiment, such as Figure 2 As shown, the connecting beam 3 and the composite pile 1 form at least two annular closed structures, with at least one annular closed structure located in one of the annular closed structures.

[0073] Specifically, in this embodiment, the combined pile 1 and the connecting beam 3 form a circular or polygonal ring structure. There can be two or more ring structures. When a smaller-diameter ring is concentrically arranged within another larger-diameter ring, it forms a double-row ring. In other embodiments, multiple rings with overlapping diameters can be nested within a larger-diameter ring, or multiple rings with progressively increasing diameters can be arranged concentrically. The annular columnar reef ring 100 formed by multi-layered or combined rings more closely resembles the complex reef structures in the natural environment, providing a more suitable habitat for fish and aquatic life.

[0074] For tidal flats with numerous gullies or severe erosion, this invention employs a double-layered circular or polygonal structure to regulate the flow velocity in shallow areas, cut off gullies on the tidal flat surface, prevent further erosion, stabilize the tidal flat surface, and create a shallow tidal flat environment that is prone to siltation, thus creating conditions for the formation of an ecological substrate.

[0075] In one embodiment, such as Figure 3 As shown, the combined pile 1 of the annular columnar artificial reef ring 100 includes a pile foundation 101, a second connector 102 and a connecting rod 103. At least three pile foundations 101 are vertically arranged in the mudflat. Multiple second connectors 102 are correspondingly arranged on the pile foundations 101. The two ends of multiple connecting rods 103 are respectively connected to the second connectors 102 on the adjacent pile foundations 101. The connecting rods 103 and the pile foundations 101 form a polygonal structure.

[0076] Specifically, in this embodiment, the pile foundation 101 is not specifically limited. To conform to reality, the pile foundation 101 in this embodiment is cylindrical and made of bamboo. The pile foundation 101 is divided into two parts: the soil-penetrating section and the body section. The length of the pile foundation 101 is determined according to the water depth and silt layer thickness of the water area. To conform to reality, the length of a single pile foundation 101 in this embodiment can be 6m, the length of the soil-penetrating section is not less than 2m, and the length of the body section is 4m.

[0077] In this embodiment, the number of pile foundations 101 is not specifically limited, but the number of pile foundations 101 should be no less than three. At least three pile foundations 101 are vertically set in the mudflat. Multiple second connectors 102 are installed on each pile foundation 101. Connecting rods 103 are respectively connected to the second connectors 102 on adjacent pile foundations 101, so that the connecting rods 103 are arranged in parallel multi-layers.

[0078] In this embodiment, the material of the connecting rod 103 is not specifically limited. To conform to the actual situation, the connecting rod 103 is made of bamboo in this embodiment.

[0079] In this embodiment, multiple composite piles 1 are interconnected by connecting beams 3 to form a ring, creating an area, thereby achieving the goal of large-scale coastal zone management. Using bamboo to construct the enclosure not only connects the individual artificial reefs of the composite piles 1 into a unified whole, resulting in reasonable stress distribution and greater stability, but also encloses a body of water to form an ecological field 200, greatly enhancing the effectiveness of the artificial reef. The annular columnar artificial reef ring 100 is typically arranged in a single layer; however, for tidal flats with numerous gullies or severe erosion, a double-layer arrangement can be used.

[0080] In this invention, the composite pile 1 adopts a frame composed of at least three pile foundations 101 with an open structure. When the waves pass through the pile foundations 101, it has a wave-dissipating effect, which makes the waves in the water area enclosed by the annular column reef ring 100 smaller, reduces the interference of hydrodynamics such as tides and waves, avoids the loss of sediment in the water area, and thus allows more nutrients to accumulate.

[0081] In one embodiment, such as Figure 5 and Figure 6 As shown, there are three pile foundations 101, which are arranged at the vertices of an equilateral triangle.

[0082] Specifically, in this embodiment, each composite pile 1 has three pile foundations 101. Based on the stability of the triangle, the three pile foundations 101 are set at the vertices of the plane equilateral triangle. The three sides of the triangle are all connected by the first connecting rod 103, forming a triangular frame column with the three pile foundations 101.

[0083] In this embodiment, to conform to the actual situation, the side length of the equilateral triangle of the composite pile 1 should be between 500mm and 800mm. Five vertically spaced connecting rods 103 are set between the three pile foundations 101; specifically, one is set at the mud surface, and another is set at intervals of about 1.0m above it.

[0084] In this embodiment, combining multiple composite piles 1 in an orderly manner can prevent damage caused by wave impact and achieve a better protective effect. When the number of composite piles 1 is equal, and thus the perimeter is equal, the enclosed area of ​​the circle is the largest, and the circular component has the best stress distribution.

[0085] In this embodiment, two types of enclosure structures are provided: a small enclosure consisting of three piles 101 forming a composite pile 1; and a large enclosure consisting of several composite piles 1 forming a circular or polygonal enclosure. The small enclosure is a reef, and the large enclosure is an ecological field 200. The small enclosure is triangular, and the large enclosure is circular.

[0086] In this embodiment, the ecological field 200 is the spatial distribution of the comprehensive ecological effects generated by biological life activities. Aquatic plant floating islands are set within the enclosure of the annular columnar reef ring 100. These islands float without anchor chains and are restricted by the enclosure, preventing them from drifting outwards. Aquatic plants continuously grow within the ring, while plankton such as fish and shrimp reproduce and thrive. Various organisms attract each other and continuously move in, forming a "closed" conservation area. The interactions between organisms and between organisms and the environment within the ecological field 200 collectively construct a marine ecosystem.

[0087] In this embodiment, although the enclosed ring is transparent, the enclosed water area will gradually form a site effect and agglomeration effect, forming an ecological field 200, attracting fish and other plankton, and providing them with a habitat.

[0088] The present invention arranges the three pile foundations 101 in a triangular structure, which can make the composite pile 1 have better stability.

[0089] In one embodiment, such as Figure 3 As shown, the bottom of the pile foundation 101 is provided with a conical pile head 104.

[0090] Specifically, in this embodiment, the conical pile head 104 is fixedly connected to the bottom of the pile foundation 101, with the tip of the conical pile head 104 pointing downwards and the interior being a cavity.

[0091] The present invention provides a conical pile head 104 at the bottom of the pile foundation 101, which facilitates the installation of the pile foundation 101 in the tidal flat during construction.

[0092] In one embodiment, such as Figure 3 As shown, the conical pile head 104 is provided with a filler 105.

[0093] Specifically, in this embodiment, the pile foundation 101 is internally connected to the conical pile head 104. In this embodiment, the filling element 105 is not specifically limited. To conform to reality, in this embodiment, the filling element 105 is concrete. The concrete is poured through holes drilled on the outside of the cylinder wall of the pile foundation 101. The length of the concrete pouring is calculated and determined according to the required weight.

[0094] The present invention provides a filler 105 inside the conical pile head 104, which increases the weight of the conical pile head 104 and causes the overall center of gravity of the pile foundation 101 to shift downward, thereby ensuring the stability of the pile foundation 101.

[0095] In one embodiment, such as Figure 7 and Figure 9 As shown, the first connector 2 includes a first mounting part 201 and a first connecting part 202. The first mounting part 201 is mounted on the composite pile 1, and the first connecting part 202 is disposed on the first mounting part 201. The first connecting part 202 is connected to the connecting beam 3.

[0096] In this embodiment, there are two ways to connect the composite pile 1 and the connecting beam 3:

[0097] First, the pile foundations 101 at the vertices of the triangular composite pile 1 are connected in pairs, that is, the two ends of the connecting beam 3 are respectively connected to the pile foundations 101 located at the vertices of two adjacent composite piles 1, specifically, as follows: Figure 9 and Figure 10 As shown, the first mounting part 201 of the first connector 2 adopts an arc-shaped plastic pipe clamp, and the central angle of the opening of the first mounting part 201 is 140 degrees. The first connecting part 202 adopts a plastic sleeve, with two sleeves set on both sides of the first mounting part 201, and the installation angle is 150 degrees. A galvanized iron wire is set above the opening of the first mounting part 201, with one end connected to the upper end of the first mounting part 201, and the other end used to enclose the pile foundation 101. The two are then cross-hooked. After the first mounting part 201 covers the pile foundation 101, the galvanized iron wire is clamped. The lengths of the connecting beams 3 on both sides are equal. In this embodiment, the inner diameter of the first mounting part 201 is compatible with the size of the pile foundation 101, and the inner diameter of the first connecting part 202 is compatible with the connecting beam 3.

[0098] Secondly, the two corner piles 101 at the bottom of the triangular composite pile 1 are respectively connected to the corner piles 101 in the adjacent composite pile 1. That is, the two ends of the connecting beam 3 are respectively connected to one of the bottom piles 101 in the composite pile 1. Specifically, as follows: Figure 7 and Figure 8As shown, the first mounting part 201 of the first connector 2 adopts a semi-circular plastic pipe clamp, and the first connecting part 202 adopts a plastic sleeve. The sleeve is set at the middle position outside the first mounting part 201. A galvanized iron wire is set above the opening of the first mounting part 201. One end is connected to the upper end of the first mounting part 201, and the other end is used to enclose the pile foundation 101. The two are then cross-hooked. After the first mounting part 201 encloses the pile foundation 101, the galvanized iron wire is clamped. The lengths of the connecting beams 3 on both sides are equal.

[0099] In this embodiment, to conform to reality, the length of the first connecting part 202 is not less than 200mm and the diameter is not less than 150mm. Bolt holes are provided at 2 / 3 of the length of the pipe opening of the first connecting part 202. The end of the connecting beam 3 is inserted into the first connecting part 202, and bolts are inserted after drilling to complete the installation.

[0100] In this embodiment, both types of installation parts are open-shaped, facilitating the binding of galvanized iron wire after alignment with the pile foundation 101. The connecting beams 3 are of equal length and connected in the same way. In this embodiment, the connecting beams 3 are preferably made from the middle section of bamboo, and the diameters at both ends should match the diameter of the first connecting part 202. The combined piles 1 are connected in a straight line, forming an overall circular shape. The circular size is set according to actual needs and controlled by the number of combined piles 1. The dimensions and structure of the combined piles 1 and the connecting beams 3 remain unchanged, facilitating their arrangement.

[0101] In this invention, first connecting parts 202 are respectively provided on both sides of the first mounting part 201, which facilitates the connection of the connecting beam 3 to two adjacent composite piles 1, and has the advantages of simple structure and convenient installation.

[0102] In one embodiment, such as Figure 11 As shown, the second connector 102 includes a second mounting part 1021 and a second connecting part 1022. The second mounting part 1021 is mounted on the pile foundation 101, and the two second connecting parts 1022 are disposed on both sides of the second mounting part 1021. The second connecting parts 1022 are connected to the connecting rod 103.

[0103] Specifically, in this embodiment, the second mounting part 1021 is a semi-circular plastic pipe clamp, and the second connecting part 1022 is two sleeves with an included angle of 60 degrees between the center lines of the two sleeves. The sleeve length is not less than 200mm and the sleeve diameter is not less than 150mm. Bolt holes are provided at 2 / 3 of the length of the sleeve opening. The two ends of the connecting rod 103 are respectively inserted into the sleeves. After drilling the holes, the bolts are inserted to complete the installation.

[0104] In this embodiment, the second mounting part 1021 is structurally similar to the first mounting part 201. A galvanized iron wire is installed at the opening of the semi-circular plastic pipe clamp. One end of the galvanized iron wire is connected to the upper end of the semi-circular plastic pipe clamp, and the other end is used to cross-hook around the pile foundation 101. After the pipe clamp encloses the pile foundation 101, the galvanized iron wire is secured. Thus, the three pile foundations 101 and the three connecting rods 103 together form a planar frame. These are arranged vertically along the pile foundations 101 to form a triangular columnar frame structure.

[0105] All pipe clamps are open semi-circular to facilitate aligning with pile foundation 101 and binding with galvanized iron wire; connecting rods 103 are of equal length and connected in the same way. Connecting rods 103 should preferably be made from the middle section of bamboo, and the diameters at both ends should match the diameter of the sleeve tube.

[0106] In this invention, second connecting parts 1022 are respectively provided on both sides of the second mounting part 1021, which facilitates the connection of the connecting rod 103 to two adjacent pile foundations 101, and has the advantages of simple structure and convenient installation.

[0107] In one embodiment, such as Figure 13 and Figure 14 As shown, the annular column reef ring 100 also includes a hanging net 4, which is vertically detachable and installed on the upper and lower adjacent connecting beams 3.

[0108] Specifically, in this embodiment, the hanging net 4 is a square sheet, woven from bamboo strips or plant fibers into a mesh structure. The mesh size can be set according to actual needs. Two to three ring hooks 401 are respectively provided at the upper and lower ends of the hanging net 4, and the hooks 401 are used to hang it on the connecting beam 3. The hanging net 4 is vertically hung between the upper and lower connecting beams 3. The hanging net 4 can be arranged closely together or spaced at certain intervals. Depending on actual needs, the hanging net 4 can be set on one connecting beam 3 or on both connecting beams 3.

[0109] In this embodiment, the hanging net 4 serves to slow down the water flow and can also function as a sheet-like artificial reef. The load generated by the hanging net 4 on the connecting beam 3 under buoyancy is calculated and determined based on the actual situation.

[0110] In this embodiment, the hanging net 4 is suspended from both the upper and lower ends on the connecting beam 3, ensuring the stability of the component. The hanging net 4 can degrade harmful substances in the water and provide space for microorganisms in the water to attach, grow, and reproduce. The increased number of microorganisms can further promote the degradation of pollutants in the water, creating a virtuous cycle.

[0111] In this embodiment, the installation location of the net 4 is not specifically limited. To conform to the actual situation, the net 4 should preferably be set on the backwater side to facilitate the interception of silt or reduce the erosion of the mudflats.

[0112] In this embodiment, the hanging net 4 is made of moso bamboo, a natural and ecological material, which has good biocompatibility. The surface of the hanging net 4 has a certain degree of roughness and a large specific surface area. Using bamboo to manufacture the hanging net 4 has the advantages of low cost, renewability, low environmental pollution, and biodegradability. Bamboo is a natural material with good biocompatibility, making it a material with great application potential.

[0113] In this embodiment, experiments showed that bamboo strips achieved a 74% removal rate of Chemical Oxygen Demand (COD) from water, a 95% removal rate of nitrate nitrogen (NO3-N), and a 37% removal rate of total phosphorus (TP), demonstrating a significant effect on improving water purification capacity. The bamboo strips also exhibit high levels of phospholipids and dehydrogenase activity on their surface, providing a suitable environment for microbial attachment, growth, and reproduction, thus continuously promoting the degradation of pollutants in the water.

[0114] In this invention, the hanging net 4 provides space for the attachment, growth, and reproduction of microorganisms in the water. The increased number of microorganisms can further promote the degradation of pollutants in the water, thereby creating a virtuous cycle and achieving good ecological and environmental protection effects. At the same time, placing the hanging net 4 on the receding water side can also help intercept sediment or reduce the erosion of the mudflats by tides and waves.

[0115] In one embodiment, the composite pile 1, the connecting beam 3, and the hanging net 4 are made of biodegradable materials.

[0116] In this invention, the composite pile 1, the connecting beam 3, and the hanging net 4 are made of biodegradable materials, which can effectively reduce the degree of environmental pollution and reduce the residue of waste in the coastal environment.

[0117] In one embodiment, the biodegradable material is moso bamboo.

[0118] This invention uses bamboo as a biodegradable material, which has good biocompatibility, is suitable for aquatic organisms, and facilitates the attachment and growth of algae and other aquatic organisms, forming a food ground. Bamboo material has a rough surface, a large specific surface area, abundant raw material resources, and is a natural material, offering advantages such as low cost, renewability, low environmental pollution, and easy degradation. The surface of bamboo material exhibits a high content of phospholipids and dehydrogenase activity in the microorganisms attached to it, providing space for microbial attachment, growth, and reproduction, and continuously promoting the degradation of pollutants in the water.

[0119] According to an embodiment of the present invention, on the other hand, such as Figure 15 and Figure 16 As shown, a method for constructing a coastal ecological field is also provided, using the aforementioned annular cylindrical artificial reef ring 100. The construction method includes:

[0120] Acquire sites in coastal zones requiring restoration;

[0121] Obtain the installation location of each annular columnar artificial reef ring 100 in the mudflats;

[0122] In the installation position, the pile foundation 101, the second connector 102 and the connecting rod 103 are assembled into a composite pile 1 in sequence;

[0123] Then, assemble each composite pile 1 with the first connecting piece 2 and the connecting beam 3 to form a ring-shaped column reef ring 100;

[0124] Multiple annular columnar artificial reefs 100 form an ecological field 200 at the coastal zone site to be restored.

[0125] Specifically, in this embodiment, a single composite pile 1 is a point structure. By arranging the composite piles in an enclosed circle, a closed ecological field 200 is formed from the point to the circle, and from the circle to the surface. By making reasonable arrangements in combination with the conditions and restoration requirements of the coastal zone, different coastal zone problems can be solved.

[0126] In this embodiment, multiple annular columnar artificial reef rings 100 are arranged in different ways to regulate the flow velocity in the shallow water area, cut off the shoal surface gullies, prevent further erosion of the shoal surface, stabilize the shoal surface, construct a shallow water environment that is prone to siltation, and create conditions for the formation of ecological base structures, etc.

[0127] In this bay, the shallow waters are too low, resulting in significant hydrodynamic disturbances from tides and waves, leading to sediment loss and preventing the accumulation of nutrients. The lack of a vegetated salt marsh substrate results in a low distribution of large benthic animals such as polychaetes, shellfish, crabs, and snails. The food chains / webs are fragmented and limited, leading to extremely low biodiversity. Therefore, it is necessary to mitigate water erosion, raise the beach surface, and replenish the sediment substrate. Planting seagrass in artificial ecological areas (e.g., 200m²) can create soft-bottomed habitats favored by benthic organisms and improve the bay's ecological quality.

[0128] By utilizing the artificial ecological field 200 in this invention, through the planting of aquatic plants and the deployment of artificial reefs, two functions can be combined to construct a complete and healthy tidal wetland ecosystem, providing a suitable habitat for benthic animals and fish in the coastal zone.

[0129] The annular columnar artificial reef ring 100 in this invention forms an enclosed ring that is permeable. This permeability controls and guides water flow, while also slowing the water velocity, allowing sediment to settle within the ring and intentionally creating silt deposits and beaches. The multiple annular columnar artificial reef rings 100 in the artificial ecological field 200 are independent, lightweight, suitable for soft soil foundations, and less affected by uneven settlement. They effectively control coastal erosion around the structure and adapt to changes in the surrounding topography.

[0130] This invention utilizes bamboo to achieve measures and effects in resource conservation, environmental friendliness, and low-carbon development. The ecological environment constructed using bamboo-based pile foundations (101) is eco-friendly, low-carbon, and multifunctional. It not only solves the rock source problem inherent in traditional artificial reefs, alleviating resource waste and environmental pollution caused by rock dumping, but also achieves the most economical overall investment and optimal comprehensive economic and social benefits, demonstrating the advantages of low-carbon environmental protection and resource conservation.

[0131] In coastal areas primarily affected by wind and waves, this invention employs an enclosed ring-shaped artificial reef ring 100. On one hand, it prevents wind and waves from eroding the beach surface and on the other hand, it promotes siltation. During high tide, silt enters the reef ring and settles and accumulates during low tide, raising the beach surface within the enclosed ring and thus achieving the dual function of protecting the beach and promoting siltation.

[0132] Currently, the coastal ecological environment is difficult to optimize on its own and faces the risk of further degradation. Therefore, it is urgent to take artificial measures to provide shelter for coastal areas requiring management, regulate the flow velocity in shallow waters, cut off channeling on the beach surface, prevent further erosion, stabilize the beach surface, and construct a shallow water environment that is prone to siltation, thus creating conditions for the formation of the ecological substrate. When there are channeling channels on the beach surface, in order to prevent further erosion, annular columnar artificial reefs can be arranged in a ring-like manner to cut off channeling channels, prevent further erosion, and stabilize the beach surface.

[0133] In this invention, multiple adjacent annular columnar artificial reef rings 100 enclose a body of water in a ring-shaped manner. The annular columnar artificial reef rings 100 constitute a ring-shaped ecological field 200. The enclosed circle is both an artificial reef group and can control coastal erosion. The two functions are combined into one, constructing a complete and healthy tidal flat ecosystem.

[0134] In this invention, such as Figure 15 As shown, with the ebb and flow of the tide, a relatively stable area forms outside the enclosed zone under the influence of water flow, providing a habitat for plankton and forming the outer ecological field 120; the relatively stable water area inside the enclosed zone forms the inner ecological field 110. The enclosed zone, the inner ecological field 110, and the outer ecological field 120 together constitute a single ecological field 200. Figure 16 As shown, several ecological fields 200 can be arranged as needed to form a coastal artificial ecological field system.

[0135] In this invention, all components of the annular columnar reef ring 100 have the same form and size, so the same components can be standardized and produced in the factory, which is convenient for manufacturing and processing, can also improve production efficiency, reduce material consumption, ensure product quality, reduce a lot of on-site work, and improve the engineering quality of the device.

[0136] In this invention, the annular columnar artificial reef ring 100 is divided into a factory manufacturing process and an on-site construction process. Each component is produced in a standardized manner in the factory and assembled there before being transported to the coastal waters where construction is needed, where it can be constructed on a ship.

[0137] The factory manufacturing process is as follows:

[0138] (1) Select bamboo, plastic parts, etc. according to the design dimensions and other requirements, and make connecting rod 103, connecting beam 3, first connecting part 2 and second connecting part 102 respectively. Select grass fiber, bamboo strips, etc. to make hanging net 4.

[0139] (2) Construction of composite piles 1

[0140] Bamboo was selected according to the design dimensions. The composite pile 1 consists of 3 bamboo piles 101 and multiple connecting rods 103. The 3 piles 101 are set at the vertices of a planar equilateral triangle, and the three sides are connected by connecting rods 103, forming a triangular frame column, thus forming the composite pile 1.

[0141] (3) Assemble the connecting beam 3 in the factory, that is, assemble the connecting rod 103 made of bamboo with the pipe clamp in the second connecting piece 102.

[0142] The on-site construction process is as follows:

[0143] The composite piles 1, connecting beams 3, and hanging nets 4 manufactured in the factory can all be transported to the coastal site by ship, and construction can be carried out on the ship during the tide, which is simple and convenient.

[0144] (1) In accordance with the design requirements, the enclosing ring of the annular column reef ring 100 is assembled in sections on the ship, that is, the combined pile 1 and the connecting beam 3 are assembled, and then the hanging net 4 is assembled.

[0145] (2) After completing the above steps, in the designated water area, use equipment on the ship to lift a section of the enclosure ring and place it vertically along the side of the ship at the designated water area point. Under the action of weight, the enclosure ring sinks to the mud surface. Set the pile driving wooden block 5 on top of the combined pile 1, and hammer or statically press it on the ship to drive the combined pile 1 into the tidal flat foundation.

[0146] Similarly, construct other segmented enclosure rings using the same method and connect them sequentially, then construct the next annular columnar reef ring 100 in sequence.

[0147] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
