Description

Technical Field

[0001] The present invention belongs to the technical field of coastal engineering, and in particular relates to a modular movable ecological submerged dike and an implementation method thereof. Background Art

[0002] As an underwater structure parallel to the coastline, the submerged dike reflects and transmits waves, causing them to break prematurely, significantly reducing wave energy. At the same time, it can change the distribution of coastal currents, making the flow rate more uniform and reducing the risk of local erosion. In addition, compared with traditional upright dikes, the submerged dike is submerged underwater, reducing damage to the coastal landscape and meeting hydrophilic needs.

[0003] However, traditional submerged dikes suffer from four drawbacks: First, they have poor ecological compatibility. Traditional concrete structures destroy benthic habitats and lack an ecological interface. Second, they are immobile. Fixed structures are difficult to adapt to the dynamic demands of shoreline changes or extreme climate events. Third, their materials are unsustainable, consuming large amounts of natural aggregate and failing to recycle dredged waste. Fourth, their functionality is limited, focusing solely on wave-breaking performance while neglecting ecological restoration and water purification. Summary of the Invention

[0004] The purpose of the present invention is to address the shortcomings of traditional submerged dikes and propose a modular movable ecological submerged dike and its implementation method to achieve movable and dredged soil reuse, as well as ecological construction and water exchange functions.

[0009] The flexible airbag is symmetrically arranged in the first accommodating cavity and fixed to the bottom of the dredged material container, and the internal filling material is one of water and air or a mixture of the two;

[0010] The fish reef-like hollow body is arranged in the second accommodating cavity to reduce wave energy;

[0011] The ecological submerged dike is fixedly installed on the seabed through an anchoring structure.

[0012] In some embodiments, the volume of the flexible airbag needs to be sufficient to enable the ecological submerged dike to float in water when filled with standard pressure air. The flexible airbag is provided with a two-way valve for inflation or deinflating or draining.

[0013] When the flexible airbag is filled with a mixture of water and air, the volume of water accounts for 40% to 60%;

[0015] In some embodiments, the flexible airbag is made of a multilayer composite material of a fabric base and a rubber sealing layer, the fabric base is polyamide PA66 or polyester fiber, and the rubber sealing layer is nitrile rubber or EPDM rubber.

[0016] In some embodiments, the size of the second accommodating cavity is adapted to the shape of the fish reef-like hollow body, and the gap between the two is controlled to be 5 mm to 10 mm.

[0017] In some embodiments, the wave-facing surface of the fish-reef-like hollow body is provided with a plurality of water-permeable holes; the material of the fish-reef-like hollow body is permeable ecological concrete.

[0018] In some embodiments, an assembled groove is provided on the top of the column of the main frame, and a self-locking column adapted to the assembled groove is provided on the bottom of the dredged material container, and the self-locking column is fixed in the assembled groove.

DETAILED DESCRIPTION

[0042] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0043] Example 1: A modular movable ecological submerged dike

[0044] like Figure 1 and 2 As shown, the modular movable ecological submerged dike of the present invention includes one or more submerged dike units, each of which includes a main frame 100, a dredged material container 200, submerged plants 300, one or more flexible air bags 400, a fish reef-like hollow body 500 and an anchoring structure, wherein:

[0045] Combine Figures 3 to 5As shown, the main frame 100 includes a top plate 101, a partition plate 102, and a bottom plate 103 arranged in parallel from top to bottom, and columns 104 vertically fixedly connected to the top plate 101, partition plate 102, and bottom plate 103; a first accommodating cavity 105 is formed between the top plate 101 and the partition plate 102, and a second accommodating cavity 106 is formed between the partition plate 102 and the bottom plate 103; connecting components are also provided on both sides of the main frame 100 for assembling the submerged dike unit;

[0046] The dredged material container 200 is provided on the top of the main frame 100 and is used to fill the dredged soil and plant submerged plants 300;

[0047] The flexible airbags 400 are symmetrically arranged in the first accommodating chamber 105 and fixed to the bottom of the dredged material container 200. The internal filling material can be selected from water and air or a mixture of the two according to needs to achieve the floating, movement and sinking of the ecological submerged dike, as well as partial wave-breaking functions; the flexible airbags 400 are symmetrically arranged to ensure the stability of the ecological submerged dike during floating transportation.

[0048] The fish reef-like hollow body 500 is disposed in the second accommodating chamber 106 to reduce wave energy;

[0049] The above-mentioned ecological submerged dike is fixedly installed on the seabed through an anchoring structure.

[0050] The volume of the flexible airbag 400 needs to be sufficient to enable the ecological submerged dike to float in the water when it is filled with standard pressure air. It is preferably made of high-strength flexible material, specifically a multi-layer composite material of a fabric base and a rubber sealing layer, the fabric base is polyamide PA66 or polyester fiber, and the rubber sealing layer is nitrile rubber or EPDM rubber; the flexible airbag 400 is provided with two two-way valves 401 (such as Figure 2 As shown), filling and exhausting or filling and draining are performed through the two-way valve 401;

[0051] When the flexible airbag 400 is filled with a mixture of water and air, the volume proportion of water is 40% to 60%.

[0052] like Figure 6 As shown, the flexible airbags 400 are preferably multiple and arranged in a staggered manner, with adjacent flexible airbags 400 maintaining a gap to reduce the impact of waves on the flexible airbags 400 and improve the stability of the ecological submerged dike.

[0053] The flexible airbag 400 is filled with water during assembly before entering the water to make the submerged dike sink; after the submerged dike is anchored, a pumping device is used to extract part of the water in the flexible airbag 400, and then a high-pressure inflator is used to inflate the flexible airbag 400. At this time, the flexible airbag 400 contains a mixture of gas and water. When the waves hit, the water in the flexible airbag 400 shakes to dissipate the energy of the waves; when the submerged dike needs to float or move, a high-pressure inflator is used to inflate the flexible airbag 400 to drain the water, thereby driving the submerged dike to float.

[0054] like Figure 2 As shown, the size of the second accommodating cavity 106 is adapted to the shape of the fish-reef-like hollow body 500, and the gap between the two is controlled to be 5 mm to 10 mm to prevent the fish-reef-like hollow body 500 from shaking violently under the action of waves.

[0055] Baffles 110 are provided on the upper and lower sides of the second accommodating chamber 106, respectively. These baffles 110 are removably fixed to the bulkhead 102 or the bottom plate 103 of the main frame 100. When assembling the submerged dike unit, the fish reef-like hollow body 500 is first placed into the second accommodating chamber 106, followed by the baffles 110 to prevent displacement of the fish reef-like hollow body 500 during movement or under the impact of waves.

[0056] like Figure 2 As shown, the wave-facing surface of the fish reef-like hollow body 500 is provided with a plurality of water-permeable holes 501 to facilitate water exchange. The material of the fish reef-like hollow body 500 is preferably ecological concrete with a certain degree of water permeability.

[0057] like Figure 7 As shown, an assembly groove 109 is provided on the top of the column 104 of the main frame 100, and a self-locking column 201 adapted to the assembly groove 109 is provided on the bottom of the dredged material container 200. The self-locking column 201 is inserted into the assembly groove 109 to complete the assembly of the dredged material container 200.

[0058] The main frame 100 and the dredged material container 200 are both made of steel structure materials coated with an anti-corrosion layer. The fixed connection method of each part of the main frame 100 is a common detachable connection such as bolt connection, which is convenient for transportation and loading and unloading.

[0059] The dredged soil in the dredged material container 200 is sealed and packaged in high-strength sealing film bags, and a submerged plant 300 is planted in each sealing film bag. Preferably, the sealing film bag is sealed with elastic rubber material to prevent the dredged soil from overflowing without affecting the growth of the submerged plant 300.

[0060] like Figures 3 to 5As shown, the connecting parts provided on both sides of the main frame 100 include connecting grooves 107 and connecting protrusions 108. In order to reduce the deadweight of the submerged dike unit, the connecting grooves 107 and connecting protrusions 108 are not limited to the sizes shown in the figure, and can be reduced according to actual needs, or the connecting grooves 107 and connecting protrusions 108 are preferably hollow structures. Figure 8 and Figure 9 As shown, the connecting grooves 107 and connecting protrusions 108 of adjacent submerged dike units are snap-fitted and fixed by inserting the pins 111 .

[0061] The anchoring structure of the present invention is a composite foundation of vacuum suction anchors and screw piles, wherein a winch (not shown in the figure) is provided on the main frame 100. The screw piles driven into the seabed are connected to the winch on the main frame 100 via an anchor chain. The structural stability can be ensured by adjusting the tension of the anchor chain.

[0062] Example 2: A modular movable ecological submerged dike implementation method

[0063] The implementation method of the modular movable ecological submerged dike based on the above embodiment 1 includes the following steps:

[0064] S1: Transport the split components of the modular movable ecological submerged dike to the construction site. Since the ecological submerged dike adopts a modular and assembled design, transportation and loading and unloading are relatively easy;

[0065] S2: Install the fish reef-like hollow body 500 in the second receiving cavity 106 of the main frame 100, fill the flexible airbag 400 with water and place it in the first receiving cavity 105 of the main frame 100, fix the dredged material container 200 on the top of the main frame 100, and place the sealed film bag planted with submerged plants 300 in the dredged material container 200, thus completing the assembly of the submerged dike unit;

[0066] S3: Use a crane to lower the assembled submerged dike unit into the water. Underwater photography equipment is used to assist the crane in the construction. The second submerged dike unit is aligned with the first submerged dike unit and connected together through the connecting grooves 107 and connecting protrusions 108 on both sides of the main frame 100. Repeat the operation as needed to assemble multiple submerged dike units to complete the assembly of the modular mobile ecological submerged dike.

[0067] S5: Anchor the connected modular movable ecological submerged dike. After the submerged dike is anchored, a portion of the water in the flexible airbag 400 is extracted using a pumping device, and then the flexible airbag 400 is inflated using a high-pressure inflator. After the construction is completed, the wave-breaking and ecological conservation functions are realized.

[0068] S6: When the position and angle of the modular movable ecological submerged dike need to be changed, the anchoring operation is performed to hoist the modular movable ecological submerged dike. First, a high-pressure inflator is used to inflate the flexible airbag 400 and drain the water, so that the modular movable ecological submerged dike floats on the water surface.

[0069] S7: The modular movable ecological submerged dike is moved to the designated location using a traction device, and the flexible airbag 400 is then filled with water and exhausted to allow the dike to sink. After anchoring is completed, the dike can achieve the functions of wave breaking and ecological maintenance at the new location.
