Abstract
Description
Technical Field
[0001] This utility model relates to a composite artificial reef, characterized by: a flat or arc-shaped plate with tenon and mortise structure made of reinforced concrete with multiple holes (round holes, triangular holes, square holes, polygonal holes and various irregular holes), combined with round rods to form a cross-shaped, triangular, grid-shaped, pyramid-shaped and various irregularly shaped reef body. Background Technology
[0002] Currently, most artificial reefs are bulky, with relatively small surface areas per unit hollow volume, resulting in high manufacturing, transportation, and deployment costs. Some artificial reefs lack consideration for water upwelling and eddies, leading to relatively low oxygen levels within the reef and a tendency for reefs in areas with thick silt to sink. This invention addresses this by creating perforated plate-like and rod-like (circular, triangular, square) shapes, facilitating manufacturing and transportation and reducing costs. Hollow cubes formed by perpendicularly combining two or more plates have a large surface area; flat or curved surfaces facilitate water upwelling, and perforations create eddies, promoting seawater exchange and increasing oxygen levels within the reef. In areas with thick silt, inserting multiple wooden or concrete rods into the holes at the bottom of the reef prevents sinking, while installing rods in the holes in the middle or upper parts of the plates increases surface area and provides suspension. Summary of the Invention
[0003] Design a modular artificial reef, comprising perforated plates and rods, both made of reinforced concrete; the plates have mortise and tenon structures, and two or more plates are joined together by the mortise and tenon structures to form a cross-shaped, triangular, grid-shaped, or pyramid-shaped polyhedral reef; the plates are planar or arc-shaped, with a triangular, quadrilateral, or irregular outline, and a thickness of 1 cm to 100 cm; the plates have round, triangular, square, or geometrically irregular holes, and the holes on the plates are divided into bottom rod holes and central holes; the plate surface has an inclination, which can generate upwelling and eddies, increasing the oxygen content of the seawater around the reef; the rods are circular, triangular, elliptical, or irregularly shaped; the rods can be fitted into the bottom rod holes and central holes respectively; rods can be installed on soft seabed geology, while they can be omitted on hard seabed geology. The plates include a lower plate, an upper plate, and an outer hanging plate; the lower plate is vertically arranged, the upper plate and the lower plate are interlocked in a cross shape, and the outer hanging plate and the lower plate are interlocked in a cross shape. The rods installed in the bottom rod holes serve to stabilize the reef and prevent it from sinking; the rods installed in the middle holes of the plate serve to increase the attachment surface area and form a suspension structure. The rods can be installed or not depending on the on-site usage requirements. Attached Figure Description

[0007] Figure 4 is a plan view of the outer panel of the combined artificial reef, which includes: outer panel (7), tenon and mortise joint (9), bottom rod hole (3), and middle hole (2).
[0008] Figure 5 is a plan view of the front and cross-section of the rod (10). Detailed Implementation
[0009] The specific implementation method of the combined artificial reef is as follows: the lower plate (6) is perpendicular to the ground, the upper plate (8) is cross-shaped with the lower plate and is inserted through the tenon and mortise (4 and 5); the outer plate (7) is cross-shaped with the bottom plate and is inserted through the tenon and mortise (9 and 1); the rod (10) is inserted into the hole (3) or the hole (2).
[0010] The holes in the plate are divided into bottom rod holes and center holes. The rods can be selectively installed according to the actual geological conditions of the sea area. Installing the rods in the bottom rod holes stabilizes the reef and effectively prevents it from sinking on soft seabeds. Installing the rods in the center holes increases the attachment area for marine organisms and forms a suspension structure. If the seabed is hard, the rod installation can be omitted, simplifying the installation process.
[0011] This utility model features a planar or arc-shaped plate with an inclined surface, which naturally creates upwelling and eddies underwater, accelerating seawater exchange around the reef and effectively increasing local seawater oxygen levels, making it more suitable for marine life to inhabit and reproduce. The plates can be flexibly assembled into various polyhedral structures such as crosses, triangles, grids, and pyramids, making assembly convenient, transportation and deployment costs low, and applicable to a wide range of applications.
