Description

Technical Field

[0001] This utility model relates to the field of floating ecological protective shell technology, and in particular to a floating ecological protective shell structure suitable for immersed tunnels. Background Technology

[0002] Immersed tunnels are a type of tunnel used for underwater passage, commonly found in projects such as high-speed railways, urban rail transit, or underwater pipelines. Their ecological cladding design aims to minimize the impact on the aquatic ecosystem by providing suitable environmental protection to the tunnel from marine erosion, while simultaneously maintaining the ecological balance of the waters.

[0003] Traditional floating ecological protective shells are typically made of environmentally friendly materials and possess a certain degree of buoyancy, allowing them to float stably on or underwater. They are designed to effectively protect immersed tunnels from damage caused by water flow, salt spray, and other natural factors, while providing habitats for underwater organisms and enhancing ecological diversity.

[0004] The reason why the concrete surface of traditional immersed tunnels easily promotes barnacle attachment is mainly due to its rough and uneven surface, which provides a fixed growth site for marine organisms such as barnacles. Barnacle growth not only accelerates the corrosion of the tunnel surface but also disrupts the marine ecological balance. Large-scale barnacle attachment reduces the habitat space for underwater organisms, affects the stability of the ecosystem, and leads to a decline in the numbers of other marine species, thus adversely affecting the entire marine environment. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a floating ecological protective shell structure suitable for immersed tunnels, aiming to improve the problem that the concrete surface of traditional immersed tunnels easily promotes barnacle attachment, affecting the stability of the ecosystem and leading to a decline in the number of other marine species.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a floating ecological protective shell structure suitable for immersed tunnels, comprising:

[0007] The protective shell body adopts a gradient functional composite structure, consisting of an outer layer and a middle layer;

[0008] Microfluidic channel network: integrated inside the protective shell body;

[0012] The outer layer is a 3D-printed bioactive ceramic with coral larvae and calcified bacteria implanted within its microporous structure; the middle layer is a fiber-reinforced geopolymer.

[0013] As a further description of the above technical solution:

[0014] The outer layer, through the action of seawater, allows coral larvae and calcified bacteria to coexist and form the coral reef matrix.

[0015] As a further description of the above technical solution:

[0016] The middle layer is a fiber-reinforced geopolymer, reinforced with basalt fibers, which improves the structural mechanical properties and corrosion resistance.

[0017] As a further description of the above technical solution:

[0018] The microfluidic channel network uses tidal energy to drive seawater circulation and deliver nutrient solution to the outer layer of the shell body.

[0021] As a further description of the above technical solution:

[0022] The underwater spectral imager is used to monitor the growth status of corals and generate carbon sink-related data to support ecological benefit certification.
