An improved marine life sanctuary assembly that is completely underwater and is designed to duplicate a natural mangrove that provides protection and promotes an underwater ecosystem, which can help reverse the decline in the fish population, aviary habitats, erosion, and the like and help to promote land and marine colonization.

An artificial reef structure including thin tensile members as part of the structure. These tensile members readily accumulate marine life to create a more organic structure. The reef structure can accommodate a wide variety of ocean sensing and communication systems. Embedded lighting and electronic elements can be used to attract and monitor marine life.

Provided is an artificial reef, including a bottom plate, a reef main body of a hollow structure and connected to the bottom plate, and a pipe rack arranged in the reef main body. Two ends of the reef main body are open. All sides of the reef main body are obliquely arranged from bottom to top towards an inner side. The pipe rack is formed by assembling multiple pipe bodies into a grid shape. The pipe bodies are in communication with each other at intersections. Both ends of each pipe body extend through and are fixed to two sides of the reef main body respectively to communicate with the outside. The bottom plate and the reef main body are made of a reinforced concrete structure, and the reinforced concrete structure is made of high corrosion-resistant steel bars and modified seawater and sea sand concrete.

Architected artificial reefs including modules of optimally arranged and sized multiple porous cylindrical bodies achieve an unprecedented wave energy dissipation rate, quantified through an equivalent drag coefficient of the order of 20, providing coastal protection against storms using a fraction of the material required in conventional artificial reefs. Selected porosity and selected material for the bodies within each reef module preserves the capacity for high drag coefficient, while offering the added advantages of ensuring a shelter to marine life, as well as making the building of the reefs in the field modular and efficient. Optimization of the dimensions and location of the multiple cylinders allow targeted design to fit the specific wave characteristics and bottom topography of the location to be protected. Architected artificial reefs with multiple porous and non-porous cylinders with overall diameters comparable to the wave height lead to high drag coefficients.

The present disclosure discloses a dredged soil utilization-based artificial reef structure and a processing method thereof, and belongs to the technical field of artificial reefs. The dredged soil utilization-based artificial reef structure includes a dredged soil artificial reef structure, and the dredged soil artificial reef structure includes a first dredged soil reef, a second dredged soil reef, and a third dredged soil reef; annular sliding chutes are formed in eccentric positions of upper surfaces of the first dredged soil reef and the second dredged soil reef; annular metal meshes are movably connected into the two annular sliding chutes; and a heavy block, a first floating block, and a second floating block are respectively embedded into placement slots of the three reefs in sequence. The artificial reef structure is processed by using dredged soil. Dredged soil resources are from the ocean and then are returned to ocean restoration, which satisfies the concept of resource recycling. Furthermore, a surface of dredged soil has multiple grooves, which is convenient for attachment of corals to achieve the purpose of ecological restoration of coral reefs, so that habitats, breeding places, and foraging places are provided for aquatic organisms such as fish to escape from natural enemies, playing an important role in the stability of an ecological system.
