Embodiment 1

[0038] Such as figure 1 As shown, the sedimentation promoting device provided by the embodiment of the present invention includes: a first bank fixing component 1 and a first culture medium 2, the first bank fixing component 1 is connected to the first culture medium 2, and the first bank fixing component 1 is used for Adsorption of reef-building organisms; the first medium 2 is used to cultivate algae plants.

[0039]Specifically, reef-building organisms such as oysters and barnacles are transplanted onto the first bank-fixing component 1 by means of artificial transplantation, and the oysters and barnacles adsorbed on the first bank-fixing component 1 can form a rough surface, thereby increasing the water flow. drag, thereby reducing water velocity and promoting sediment deposition. Oysters can grow on the first bank fixing component 1 to form a biological reef, and the diffusion and growth of oysters can enhance the stability of the biological reef and increase the deposit...

Embodiment 2

[0052] The natural coastline generation method provided by the embodiment of the present invention includes the following steps:

[0053] The first culture medium 2 is placed in the subtidal zone where the water depth is less than or equal to 6m at low tide and greater than 2m.

[0054] Further, the second culture medium 4 is placed in the subtidal zone where the water depth is less than or equal to 2m at low tide and greater than 0m.

[0055] Specifically, when treating the artificial coastline on the outside of the seawall 6, select a suitable silt-promoting method according to the depth of the low tide. In the subtidal zone where the water depth is less than or equal to 6m and greater than 2m at low tide, algae plants are cultivated in the water to increase the resistance of the stems and leaves of the algae plants to the water flow, thereby accelerating sediment deposition; at low tide, the water depth is less than or equal to 2m and greater than 0m in the subtidal zone S...

Abstract

The invention provides a siltation promotion device and a natural coastline generation method, and relates to the technical field of coastal zone regulation remediation technologies. The siltation promotion device provided by the invention comprises first bank strengthening assemblies and a first culture medium; the first bank strengthening assemblies are connected with the first culture medium and are used for adsorbing reef-building organisms; and the first culture medium is used for breeding algae. Through the siltation promotion device provided by the invention, the technical problem thatecological siltation promotion underwater construction is difficult to conduct is solved, the reef-building organisms can diffuse and grow on the first bank strengthening assemblies, an organic reef body is formed, water flow resistance can be increased, silt deposition is facilitated, and a matrix and nutriment are provided for the algae; the algae and the organic reef body act together, thus, the water flow resistance can be further increased, and regional silt is made to be deposited; and moreover, the first bank strengthening assemblies and the first culture medium can be arranged underwater, underwater construction is carried out conveniently, the beach face can be promoted to rise in the ecological mode, and a natural coastline is generated outside the sea wall in an accelerated mode.

Description

technical field [0001] The invention relates to the technical field of coastal zone regulation and restoration, in particular to a silt-promoting device and a method for generating a natural coastline. Background technique [0002] The coastline is an important natural resource of our country, and it is also an important carrier for the development of coastal economy and the construction of marine ecological civilization. According to the "Coastline Protection and Utilization Management Measures", natural coastlines can be divided into sandy coastlines, muddy coastlines, bedrock coastlines, biological coastlines and other primary coastlines. Functional coastlines are included in the management of natural coastline management and control objectives. [0003] The silting-promoting device and silting-promoting method in the prior art mainly include: silting-promoting devices based on permanent physical buildings, such as spur dams, submerged lock dams, geotechnical woven bag d...
