[0001] Cross-reference to Related Applications

[0002] The present application claims priority to the Chinese patent application No. 202411249174.1, filed on September 6, 2024, and entitled "A ring column type fish reef ring and a method for constructing a coastal zone ecological field", the entire content of which is incorporated herein by reference. TECHNICAL FIELD

[0003] The present application relates to the technical field of water environment engineering, in particular to a ring column type fish reef ring and a method for constructing a coastal zone ecological field. BACKGROUND

[0004] The coastal zone is a geographical unit that connects the marine system and the terrestrial system, and is a composite and cross-over geographical unit. It is not only the most active natural region on the earth's surface, but also the region with the most superior resources and environmental conditions. It is an independent environmental system with the characteristics of sea-land transition, and the interaction of coastal dynamics and land. It is most closely related to human survival and development. With the rapid increase in population and the acceleration of urbanization, the coastal zone is facing enormous pressure from global climate change, sea level rise, regional ecological environment destruction, biodiversity reduction, pollution, and degradation of fishery resources, which seriously affects the sustainable development of the coastal zone.

[0005] At present, most of the traditional coastal zone restoration uses natural stone blocks or artificial reefs to reconstruct the intertidal habitat and protect the intertidal biodiversity. However, since the reefs are point structures, they cannot form a large area of treatment effect on the coastal zone. If a large area is arranged with individual reefs, the investment is large. In addition, when the coastal zone is a muddy beach, artificial reefs made of concrete frames are easily sunken in the silt due to their large weight, and there is little substrate available for fish and aquatic life to move around, making it difficult to function as expected.

DETAILED DESCRIPTION

[0054] In order to make the purposes, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0055] In the related art, most of the traditional coastal zone restoration is to arrange fish reefs in the coastal zone. However, some coasts are muddy, and the silt on the beach is thick, which is not conducive to the arrangement of traditional fish reefs, and the effect of the scattered fish reefs is limited.

[0056] Most of the traditional fish reef materials are “cold” materials such as concrete and plastic, which lack affinity. Fishes and aquatic organisms need to adapt first, and then can become the habitat of fishes. Since the weight of such fish reefs is large, they are easy to sink in the silt, and there is little bed for fishes and aquatic organisms, thereby causing the function of the fish reefs to be greatly reduced.

[0057] If the fish reefs are arranged improperly, the fish reef group formed by the scattered arrangement of the traditional fish reefs aggravates the beach scouring and forms new beach gullies.

[0058] The traditional fish reefs are arranged in the form of adjacent arrangement, which forms a fish reef group, but on a large beach, it is only a large point structure and does not have the effect of surface management.

[0059] The embodiments of the present application will be described below with reference to FIGS. 1 to 16.

[0060] According to the embodiments of the present application, on the one hand, as shown in FIGS. 1 to 14, an annular columnar fish reef ring 100 is provided, which comprises a combined pile 1, a first connecting piece 2, and a connecting beam 3. The plurality of combined piles 1 are vertically arranged in the beach, the plurality of combined piles 1 are arranged in a circumferential direction, the plurality of first connecting pieces 2 are arranged on the combined piles 1 correspondingly, and the plurality of connecting beams 3 are arranged side by side. The two ends of the connecting beam 3 are connected with the first connecting pieces 2 on the adjacent combined piles 1 respectively, and the connecting beam 3 and the combined pile 1 enclose an annular closed structure.

[0061] Specifically, the annular columnar fish reef ring 100 in the embodiment is applied to the beach of the coastal zone. The beach in the embodiment is not limited, and the beach in the embodiment is a soft soil beach with uneven settlement.

[0062] As shown in FIGS. 1 and 4, in the embodiment, the plurality of combined piles 1 are vertically arranged, the bottom of the combined pile 1 is inserted into the beach, the plurality of combined piles 1 are arranged in a circumferential direction, and the plurality of connecting beams 3 are connected with the adjacent two combined piles 1 side by side in a transverse direction, so as to enclose the plurality of combined piles 1 into a circular or polygonal enclosure.

[0063] In the embodiment, the arrangement of the tie beams 3 is not specifically limited, and in order to be consistent with the actual situation, two layers of the tie beams 3 are arranged in the embodiment, specifically, one layer of the tie beams 3 is arranged at the design tide level of the composite piles 1, and one layer of the tie beams 3 is arranged at the highest tide level. In other embodiments, according to the height of the composite piles 1 and the geological conditions of the tidal flat, the tie beams 3 can also be arranged in other numbers of layers, in order to ensure the stability of the composite piles 1, the number of layers of the tie beams 3 should be not less than two, when the composite piles 1 sink to the abutment of the tie beams 3 and the surface of the tidal flat, the bottom layer of the tie beams 3 can play a supporting role on the tidal flat, which can avoid the sinking of the composite piles 1 too deep, thereby ensuring that the annular column type fish reef ring 100 can provide sufficient base for fish and aquatic organisms to live in the tidal flat.

[0064] In the embodiment, as shown in FIG. 1, a plurality of composite piles 1 are arranged at equal intervals on a circular circumference, and equal-length tie beams 3 are used to connect adjacent composite piles 1 to form a ring-shaped ecological field 200, in the embodiment, the radius R of the circular central axis of the single-row enclosing ring should be determined according to the coastal zone to be repaired, in order to be consistent with the actual situation, the radius R in the embodiment is not greater than 10 m.

[0065] In the embodiment, when the number of the composite piles 1 is small, the ring-shaped ecological field 200 enclosed by the composite piles 1 and the tie beams 3 is a polygon, when the number of the composite piles 1 is large, the ring-shaped ecological field 200 enclosed by the composite piles 1 and the tie beams 3 is approximately circular, and the circular structure is more reasonable in stress and can bear larger wind and wave impact.

[0066] The annular column type fish reef ring 100 formed by the composite piles 1 and the tie beams 3 in the application is a circular or polygonal structure, when the composite piles 1 are arranged in the tidal flat, the tie beams 3 between the composite piles 1 can play a supporting role on the tidal flat, which can avoid the sinking of the composite piles 1 too deep and cause the annular column type fish reef ring 100 to sink into the silt of the tidal flat, and the circular or polygonal structure becomes a habitat for marine organisms, which is conducive to maintaining the stability of the ecological environment of the coastal zone, and the vertically arranged composite piles 1 can realize the flow velocity of the shoal area, cut off the beach gully, prevent the beach from further erosion, stabilize the beach, and construct a shallow beach environment that is easy to silt up, thereby creating conditions for the formation of an ecological foundation.

[0067] In one embodiment, as shown in FIG. 2, the tie beams 3 and the composite piles 1 form at least two annular closed structures, and at least one annular closed structure is located in one of the annular closed structures.

[0068] Specifically, the combined piles 1 and the connecting beams 3 are combined into a circular or polygonal ring structure in the embodiment, and the ring structure can be two or more, and when a smaller-diameter enclosing ring is arranged concentrically in a larger-diameter enclosing ring, the two rings are combined into a double-row enclosing ring. In other embodiments, a plurality of smaller-diameter enclosing rings can be nested in a larger-diameter enclosing ring, or a plurality of enclosing rings with increasing diameters can be arranged concentrically. The multi-layer or combined enclosing ring formed by the ring-shaped columnar fish reef ring 100 is more similar to the complex fish reef structure in the natural environment, and can provide more suitable habitats for fish and aquatic organisms.

[0069] The application adopts a double-layer circular or polygonal structure for a beach with many gullies or serious erosion, so as to reduce the flow rate of the beach area, cut off the gullies on the beach, prevent further erosion of the beach, stabilize the beach, and construct a beach environment that is easy to silt up, thereby creating conditions for ecological foundation construction.

[0070] In one embodiment, as shown in FIG. 3, the combined piles 1 of the ring-shaped columnar fish reef ring 100 include pile foundations 101, second connecting pieces 102, and connecting rods 103. At least three pile foundations 101 are vertically arranged in the beach, a plurality of second connecting pieces 102 are arranged on the pile foundations 101, and a plurality of connecting rods 103 are connected to the second connecting pieces 102 on the adjacent pile foundations 101 at both ends, so that the connecting rods 103 and the pile foundations 101 form a polygonal structure.

[0071] Specifically, the pile foundations 101 are not specifically limited in the embodiment, and are cylindrical in the embodiment to conform to the actual situation. The pile foundations 101 are made of bamboo, and are divided into an earth-penetrating section and a body section. The length of the pile foundations 101 is determined according to the water depth and the thickness of the silt layer of the water area. In the embodiment, the length of a single pile foundation 101 is 6 m, the length of the earth-penetrating section is not less than 2 m, and the length of the body section is 4 m.

[0072] In the embodiment, the number of the pile foundations 101 is not specifically limited, and the number of the pile foundations 101 should be not less than three. At least three pile foundations 101 are vertically arranged in the beach, a plurality of second connecting pieces 102 are arranged on each pile foundation 101, and the connecting rods 103 are connected to the second connecting pieces 102 on the adjacent pile foundations 101, so that the connecting rods 103 are arranged in a plurality of layers in parallel.

[0073] In the embodiment, the material of the connecting rods 103 is not specifically limited, and the connecting rods 103 are made of bamboo in the embodiment to conform to the actual situation.

[0074] The plurality of combination piles 1 in the embodiment are connected to each other by the connecting beams 3 to form a circle, forming a field, so as to achieve the purpose of treating the coastal zone in a piece. The combination piles 1 are made of bamboo, which can not only make the single fish reef connected to each other to be reasonable in stress and more stable, but also can enclose a piece of water to form an ecological field 200, greatly increasing the effect of the fish reef. The annular columnar fish reef circle 100 is usually arranged in a single layer, and for the beach with more gullies or more serious erosion, the annular columnar fish reef circle 100 can be arranged in a double layer.

[0075] The combination pile 1 in the application adopts a frame composed of at least three pile foundations 101, which is a permeable structure. When the waves pass through the pile foundation 101, the waves are dissipated, so that the waves in the water area surrounded by the annular columnar fish reef circle 100 are small, the disturbance of water power such as tides and waves is reduced, and the loss of sediment in the water area is avoided, so that more nutrients can be accumulated.

[0076] In one embodiment, as shown in FIGS. 5 and 6, the number of pile foundations 101 is three, and the three pile foundations 101 are arranged at the vertex positions of an equilateral triangle.

[0077] Specifically, in the embodiment, the number of pile foundations 101 in each combination pile 1 is three, and according to the stability of the triangle, the three pile foundations 101 are arranged at the vertexes of the equilateral triangle, and the three sides of the triangle are connected by the connecting rods 103 to form a triangular frame column with the three pile foundations 101.

[0078] In the embodiment, in order to meet the actual situation, the side length of the equilateral triangle of the combination pile 1 is preferably 500mm to 800mm, and the connecting rods 103 between the three pile foundations 101 are vertically and equally spaced five times; specifically, one connecting rod 103 is arranged at the mud surface, and one connecting rod 103 is arranged every 1.0m above the mud surface.

[0079] In the embodiment, the plurality of combination piles 1 are orderly combined together to avoid damage caused by wave impact, and better protection effect can be achieved. In the case that the number of combination piles 1 is equal, the surrounding area of the circle is the largest, and the circular member is best in stress.

[0080] In the embodiment, two types of enclosing structures are provided: the small enclosing structure is that the three pile foundations 101 are enclosed to form the combination pile 1; and the large enclosing structure is that the plurality of combination piles 1 are enclosed to form a circular or polygonal enclosing circle. The small enclosing structure is a fish reef, and the large enclosing structure is an ecological field 200. The small enclosing structure adopts a triangle, and the large enclosing structure adopts a circle.

[0081] In this embodiment, the ecological field 200 is the spatial distribution of the comprehensive ecological effect generated by the biological life activities. The aquatic plant floating island is arranged in the enclosing ring of the annular columnar fish reef ring 100, is in a floating state without the need of anchor chain fixing, and the floating island cannot float outward due to the limitation of the enclosing ring. The aquatic plants grow continuously in the ring, and the plankton such as fish and shrimp breed and thrive in the ring. Various organisms attract each other, continuously move in, form a "closed" conservation, and the interaction between the organisms and the environment in the ecological field 200 jointly build the marine ecological system.

[0082] In this embodiment, although the enclosing ring is permeable, the water area enclosed by the enclosing ring will gradually form a field effect and a gathering effect, form the ecological field 200, attract plankton such as fish, and provide a habitat for them.

[0083] The three pile foundations 101 are arranged in a triangular structure in this application, so that the combined pile 1 has better stability.

[0084] In one embodiment, as shown in FIG. 3, the bottom of the pile foundation 101 is provided with a conical pile head 104.

[0085] Specifically, in this embodiment, the conical pile head 104 is fixedly connected with the bottom of the pile foundation 101, the tip of the conical pile head 104 faces downward, and the inside is a cavity.

[0086] The conical pile head 104 is arranged at the bottom of the pile foundation 101 in this application, which facilitates the installation of the pile foundation 101 in the mudflat during construction.

[0087] In one embodiment, as shown in FIG. 3, the conical pile head 104 is provided with a filler 105.

[0088] Specifically, in this embodiment, the pile foundation 101 is in communication with the inside of the conical pile head 104. In this embodiment, the filler 105 is not specifically limited, and in order to conform to the actual situation, the filler 105 is concrete in this embodiment. The concrete is poured from the hole punched on the outer side of the cylinder wall of the pile foundation 101, and the pouring length of the concrete is determined according to the required weight.

[0089] The filler 105 is arranged in the conical pile head 104 in this application, which increases the weight of the conical pile head 104, so that the overall gravity center of the pile foundation 101 moves downward, thereby ensuring the stability of the pile foundation 101.

[0090] In one embodiment, as shown in FIGS. 7 and 9, the first connecting member 2 includes a first mounting portion 201 and a first connecting portion 202.

The pile foundations 101 are arranged in sequence along the vertical direction to form a triangular columnar body frame structure.

[0100] The pipe clamps are all semicircular openings, which facilitates the binding of the galvanized iron wire after being clamped with the pile foundation 101; the connecting rods 103 have the same length and the same connection mode. The connecting rods 103 are preferably made of the middle section of a bamboo, and the diameters of the two ends are preferably matched with the diameter of the sleeve.

The microbial phospholipid content and dehydrogenase activity on the surface of the bamboo chips are large, which can provide space for the attachment, growth and reproduction of microorganisms and continuously promote the degradation of pollutants in water.

[0109] In this application, the hanging net 4 can provide space for the attachment, growth and reproduction of microorganisms in water, and the increased microorganisms can further promote the degradation of pollutants in water, thereby forming a virtuous cycle and having good ecological and environmental protection effect. At the same time, the hanging net 4 is arranged on the water recession side, which can also facilitate the interception of sediment or reduce the erosion of the tidal flat by tides and waves.

[0110] In one embodiment, the combination pile 1, the connecting beam 3 and the hanging net 4 are made of degradable materials.

[0111] In this application, the combination pile 1, the connecting beam 3 and the hanging net 4 are made of degradable materials, which can effectively reduce the degree of environmental pollution and reduce the residue of waste in the coastal environment.

[0112] In one embodiment, the degradable material is bamboo.

[0114] According to the embodiment of the application, on the other hand, as shown in Figures 15 and 16, a method for constructing a coastal zone ecological field is also provided, which uses the above-mentioned annular column type fish reef ring 100, and the construction method comprises the following steps:

[0115] Obtaining a to-be-repaired coastal zone site;

[0116] Obtaining the installation positions of the annular column type fish reef rings 100 in the mudflat;

[0117] Assembling the pile foundation 101, the second connecting piece 102 and the connecting rod 103 into a combined pile 1 in the installation positions in sequence;

[0118] Assembling each combined pile 1 into the annular column type fish reef ring 100 with the first connecting piece 2 and the connecting beam 3;

[0119] The plurality of annular column type fish reef rings 100 form an ecological field 200 at the to-be-repaired coastal zone site.

[0120] Specifically, the single combined pile 1 in the embodiment is a point type structure, and through the arrangement mode of the enclosing ring, the combined pile 1 is changed from a point to a ring and then to a piece of enclosed ecological field 200, and the ecological field 200 can be reasonably arranged in combination with the conditions of the coastal zone and the repair requirements, so that different coastal zone problems can be solved.

[0121] In the embodiment, the plurality of annular column type fish reef rings 100 are arranged in different ways, so that the flow velocity of the shoal area can be realized, the gully on the beach can be cut off, the beach can be prevented from being further eroded, the beach can be stabilized, the shoal environment which is easy to silt up can be constructed, and conditions for ecological foundation construction are created, and the like.

[0122] In the gulf, due to the fact that the shoal elevation is too low, the water power disturbance of tides, waves and the like is large, the sediment loss is large, a large amount of nutrients cannot be accumulated, and the salt marsh foundation with vegetation is lacking, so that the large benthic animals with large individuals such as polychaetes, shellfish, crabs and snails are less distributed, the food chain / web is broken, and the natural ecological biodiversity is extremely low. Therefore, on the basis of suppressing the flow erosion and raising the beach foundation, the sediment matrix needs to be supplemented, the soft bottom habitat which is preferred by benthic organisms can be created by planting seaweed in the artificial ecological field 200, and the ecological quality of the gulf can be improved.

[0123] By using the artificial ecological field 200 in the present application, through aquatic plant planting and fish reef throwing, two functions can be realized in one, and a complete and healthy tidal wetland ecosystem is constructed, which provides suitable habitat for benthic animals and fish in the coastal zone.

[0124] The enclosure formed by the ring column type fish reef ring 100 in the present application has water permeability, which can control and guide water potential on one hand, and slow down the flow rate of water flow on the other hand, so that the sediment can settle in the ring and the beach can be formed by purposeful deposition. The multiple ring column type fish reef rings 100 in the artificial ecological field 200 are independent of each other, light in weight, suitable for soft soil foundation, and less affected by uneven settlement; they can effectively control the erosion of the surrounding coastal zone and adapt to the changes of the surrounding terrain.

[0125] In the present application, bamboo is used to take measures and achieve results in resource conservation, environmental friendliness and low-carbon environmental protection. The ecological environment constructed by the pile foundation 101 made of bamboo material is ecological, low-carbon and environmentally friendly, multifunctional and multipurpose. Not only does it solve the problem of stone source in traditional fish reefs and alleviate the problems of resource waste and environmental pollution caused by rock throwing, but also it saves the most comprehensive investment and has the most optimal comprehensive economic and social benefits, with the advantages of low-carbon environmental protection and resource conservation.

[0126] In the present application, the ring column type fish reef ring 100 with an enclosure structure is used in the coastal zone mainly affected by wave erosion, which can prevent wave erosion and maintain the beach on one hand, and promote deposition on the other hand, so that the sediment enters the dam during high tide and deposits and accumulates during low tide, raising the beach within the enclosure and playing a dual role of beach protection and deposition promotion.

[0127] Currently, the ecological environment of the coastal zone is difficult to optimize itself and will face the risk of further degradation. Therefore, it is urgent to take artificial measures to provide shelter for the coastal zone in need of governance, regulate the flow rate of the shallow beach area, cut off the beach gully, prevent further erosion of the beach, stabilize the beach, and create conditions for the formation of ecological foundation construction.

[0128] In the present application, multiple ring column type fish reef rings 100 arranged adjacently enclose a piece of water into an enclosure, and the ring column type fish reef ring 100 forms a ring-shaped ecological field 200. The enclosure is not only a fish reef group, but also can govern the erosion of the coastal zone, realizing two functions in one and constructing a complete and healthy tidal wetland ecosystem.

[0129] In the present application, as shown in Fig. 15, with the rise and fall of the tide, a relatively stable area is formed outside the enclosing circle under the action of water flow, providing a habitat for plankton, forming an outer ecological field 120; within the enclosing circle, the relatively stable water area constructed provides an inner ecological field 110. The enclosing circle, the inner ecological field 110 and the outer ecological field 120 together constitute a single ecological field 200. As shown in Fig. 16, several ecological fields 200 are arranged as needed to form a piece, i.e. a coastal artificial ecological field system.

[0130] In the present application, the various components of the annular column type fish reef circle 100 are of the same form and size, so that the same components can be standardized in factory production, making processing convenient, also improving production efficiency, reducing material consumption, ensuring product quality, and reducing a large amount of on-site work, improving the engineering quality of the device.

[0131] In the present application, the annular column type fish reef circle 100 is divided into a factory production process and an on-site construction process. The components are standardized in factory production and assembled in the factory, and then sent to the coastal water area where construction is needed for on-site construction on the ship.

[0132] The factory production process is as follows:

[0133] (1) Selecting bamboo, plastic parts, etc. according to the design size and other requirements, respectively producing connecting rods 103, connecting beams 3, first connecting pieces 2 and second connecting pieces 102, and selecting grass fibers, bamboo pieces, etc. to produce hanging nets 4.

[0134] (2) Producing a composite pile 1

[0135] Selecting bamboo according to the design size, the composite pile 1 is composed of 3 bamboo pile foundations 101 and a plurality of connecting rods 103. The 3 pile foundations 101 are arranged at the vertices of a planar equilateral triangle, and the three sides are connected by connecting rods 103, forming a triangular frame column with the 3 pile foundations 101, forming a composite pile 1.

[0136] (3) Assembling the connecting beams 3 in the factory, i.e. assembling the connecting rods 103 made of bamboo with the pipe hoops in the second connecting pieces 102.

[0137] The on-site construction process is as follows:

[0138] The composite piles 1, connecting beams 3 and hanging nets 4 produced in the factory can be transported to the coastal site by ship, and the construction can be carried out on the ship at the construction site during the tide, which is simple and convenient.

[0139] (1) Assembling the enclosing circle of the annular column type fish reef circle 100 on the ship according to the design requirements, i.e. assembling the composite pile 1 and the connecting beam 3, and then assembling the hanging net 4.

[0140] (2) After the above steps are completed, a section of the enclosing ring is lifted by using equipment on the ship in the designated water area, and is placed vertically along the side of the ship at the designated water point. Under the action of the weight force, the enclosing ring sinks to the mud surface. The pile wood block 5 is arranged at the top of the combined pile 1, and the combined pile 1 is hammered or statically pressed into the beach foundation on the ship.

[0141] Similarly, other sectional enclosing rings are constructed by the same method and are sequentially connected, and the next annular column type fish reef ring 100 is sequentially constructed.

[0142] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the appended claims.
