Description

Technical Field

[0001] The utility model relates to the field of marine ecological engineering and coastal zone protection, and in particular to an ecological reef row. Background Art

[0002] Oyster reefs are aggregates of living oysters, shells of dead oysters and other reef organisms. They can reduce wave energy, shoreline erosion, and to a certain extent resist flood disasters caused by storms. Their beach protection and siltation-promoting effects also provide suitable conditions for the growth of salt marshes. In addition, oyster reefs will grow upward as sea levels rise, enhancing the resilience of coastlines to climate change. Oyster reefs are increasingly being used as a form of natural infrastructure in coastal protection and ecological coastline construction projects.

[0003] At present, there is still a relative lack of technologies for repairing oyster reefs both at home and abroad. The method represented by announcement number CN216674319U uses fixed ropes to fix the reef units to fixed rods to assemble large-scale single oyster reefs. In this method, the fixed rods are easily unstable when washed by the beach or impacted by large waves and tidal currents, and remain at the proliferation level of a single oyster reef, and no oyster reef group consisting of multiple reefs is constructed. The method represented by announcement number CN 219653629 U uses assembly components between building blocks to ensure stability, sets the reef into an arc shape, and opens multiple holes to eliminate waves. In this method, the reef is a special-shaped block, which is difficult to manufacture and has a small area for biological attachment.

[0004] Therefore, there is an urgent need to develop an oyster reef with good stability, large attachment area, good wave-breaking effect, and easy production and installation. Utility Model Content
