Description

Technical Field

[0001] This invention belongs to the field of land reclamation technology, specifically relating to a new type of land reclamation unit used for ecological island construction. Background Technology

[0002] To expand their land area and effectively utilize resources, coastal countries are vigorously developing land reclamation technology. Among existing technologies, the most mature and widely used is sand dredging and reclamation. By blowing sand to the target area, areas previously submerged by seawater are filled into sand dunes. Then, through methods such as compaction and soil improvement, structures can be built and production can be developed on the reclaimed land.

[0003] The cutter suction dredgers used in land reclamation loosen the seabed soil and coral reefs before transporting and filling the land. Coral reefs play a crucial role in the biodiversity of marine ecosystems, with one-quarter of the world's marine life depending on them for survival. Therefore, land reclamation projects targeting islands and reefs inevitably cause irreversible damage to the marine ecosystem surrounding the reefs due to the destruction of coral reefs and the occupation of the surrounding waters. Furthermore, due to the massive scale of reclamation projects, other common reclamation materials, such as natural stone and metals, also face a series of problems including resource shortages, difficulties in material transportation, and corrosion of metals. Currently, there are very few reclamation units on the market that combine island-building needs with ecological functions. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an ecological island-building reclamation unit that addresses the gaps in the existing technology. It combines load-bearing and ecological functions and has advantages such as simple structure, high mass-to-weight ratio, and ease of production and transportation.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0006] An ecological island-building reclamation unit is disclosed, comprising a central through-hole and an outer shell, a structural layer, and an inner filling layer. The outer shell is made of a neutral material to ensure that the seabed water quality and related environmental indicators remain unaffected after the reclamation unit sinks to the bottom. The structural layer is made of high-performance corrosion-resistant material to withstand the water head pressure after the reclamation unit sinks to the bottom, the pressure transmitted during unit stacking, and the mutual collision forces. The entire exterior of the structural layer is covered by the outer shell, forming a fully enclosed cavity inside. The filling layer utilizes the fully enclosed cavity formed by the structural layer to fill crushed construction waste.

[0007] In the above scheme, the reclamation unit also includes a support frame, which is located in the fully enclosed cavity formed by the structural layer. The support frame is a triangular pyramidal structure system, and the four vertices are connected and fixed to the structural layer through inherent connectors.

[0008] In the above scheme, the surface of the supporting frame is ribbed, and it fits well with the filling material of its surrounding filling layer, together forming the rigidity of the reclamation unit structure under high pressure.

[0009] In the above scheme, the diameter of the through hole exceeds 0.4m.

[0010] In the above scheme, the thickness of the outer shell surface layer is greater than 0.2m.

[0011] In the above scheme, the outer shell surface is provided with a microporous structure to create an environment conducive to the enrichment of microorganisms and plankton.

[0012] In the above scheme, the geometric dimension of the main axis of the structural layer is greater than 1.5m, and the thickness ranges from 0.01m to 0.02m.

[0013] In the above scheme, the filling layer is filled with crushed construction waste and then formed after secondary molding.

[0014] In the above scheme, the weight of the filling layer is greater than 1000 kg, which can maintain the stability of the unit under the action of weak water flow.

[0015] In the above scheme, the reclamation unit is pebble-shaped.

[0016] The beneficial effects of this invention are as follows:

[0017] The ecological island-building reclamation unit of this invention is pebble-shaped, providing a complex underwater environment that ensures ecological functions; the central through hole enriches the complexity of the underwater environment created by the reclamation unit, and together with the inter-unit gap space, it forms an interconnected flow channel, which can provide a place for plankton and small fish to reproduce, grow and shelter from predators; the outer shell surface layer is provided with a microporous structure, forming an environment conducive to the enrichment of microorganisms and plankton.

[0018] The outer shell of the reclamation unit is made of neutral materials to ensure that it will not affect the water quality and related environmental indicators of the nearshore reef area after it is submerged and put into service. The inner shell has a corrosion-resistant and high-strength structural layer, which is mainly used to withstand the water head pressure after the unit is submerged, the pressure transmitted by the unit stacking, and the mutual collision force. The enclosed space inside the structural layer is filled with crushed construction waste, which is molded to form the reclamation unit filling layer, which works in conjunction with the triangular pyramid support skeleton inside the structural layer to maintain the rigidity and stability of the unit structure under high pressure.

[0019] Large-volume reclamation units have a large volume and mass, resulting in a more stable structure after accumulation. At the same time, the accumulation of large-volume reclamation units can create greater porosity, providing more space for fish to accumulate and seek shelter from predators.

[0020] In summary, the reclamation unit of the present invention combines pressure-bearing and ecological functions, and has the advantages of simple structure, large mass-to-weight ratio, and easy production and transportation. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the accompanying drawings:

[0022] Figure 1 This is a schematic diagram of the structure of the reclamation unit for ecological island building according to the present invention.

[0023] In the diagram: 1. Outer shell layer; 2. Structural layer; 3. Filling layer; 4. Inherent connectors; 5. Support frame; 6. Through hole. Detailed Implementation

[0024] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0025] like Figure 1 As shown, this invention provides an ecological island-building reclamation unit. The reclamation unit has a pebble-like appearance, with corresponding morphological parameters tending towards a spherical shape. When each reclamation unit is stably deposited on the seabed, a certain gap must be maintained between the units. This provides a complex underwater environment that ensures ecological functions, such as shelter and enrichment for small fish, in shallow seas or lagoons where hydrodynamic forces are weak. A through-hole 6 is provided in the middle of the reclamation unit. This saves on filling material and enriches the complexity of the underwater environment created by the reclamation unit's construction. Together with the gaps between units, it forms interconnected flow channels, providing breeding, growth, and shelter for plankton and small fish. The reclamation unit includes an outer shell layer 1, a middle structural layer 2, and an inner filling layer 3. The outer shell layer 1 is made of neutral materials such as alkali-free or medium-alkali glass fiber, carbon fiber, or plexiglass to ensure that the seabed water quality and related environmental indicators remain unaffected after the reclamation unit is submerged and put into service. Structural layer 2 is made of high-performance corrosion-resistant materials, primarily to withstand the head pressure after the reclamation unit sinks to the bottom, the pressure transmitted during unit stacking, and the mutual collision forces. The entire exterior of structural layer 2 is covered by outer shell layer 1, forming a fully enclosed cavity. Filling layer 3 utilizes the fully enclosed cavity formed by structural layer 2, filling it with pulverized construction waste, and then molding it through a secondary molding process. Using pulverized construction waste in filling layer 3 addresses the issue of the enormous supply of reclamation materials; relying solely on natural materials such as stone would result in insufficient material storage. Furthermore, the use of construction waste also reflects considerations of green environmental protection and sustainable development in the construction industry.

[0026] Further optimization includes a support frame 5, which is located in a fully enclosed cavity enclosed by the structural layer 2. The support frame 5 is a triangular pyramid structure system, and its four vertices are connected and fixed to the structural layer 2 through inherent connectors 4 to ensure the spatial resistance of the unit as a whole to pressure.

[0027] Further optimization involves adding ribs to the surface of the support frame 5, which meshes well with the filling material of its outer filling layer 3, together forming the rigidity of the reclamation unit structure under high pressure.

[0028] Further optimization has resulted in the through hole 6 having a diameter exceeding 0.4m, allowing small marine fish to swim and move freely within it, providing space for fish to gather, congregate, and seek shelter from predators.

[0029] Further optimization resulted in an outer shell layer 1 with a thickness greater than 0.2 μm. The surface of the outer shell layer 1 is provided with a microporous structure, which can create an environment conducive to the enrichment of microorganisms and plankton.

[0030] Further optimization resulted in a near-spherical structure layer 2 with a main axis geometry greater than 1.5m and a thickness ranging from 0.01m to 0.02m.

[0031] Further optimization involves filling layer 3, which serves as the main bottom ballast for the reclamation unit. Its weight exceeds 1000 kg, ensuring the stability of the unit under weak water flow.

[0032] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0033] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims. All of these forms are within the protection scope of the present invention.
