Basalt fiber cay ecological restoration multi-dimensional reef

Abstract

The invention discloses a basalt fiber cay ecological restoration multi-dimensional reef which comprises a polygonal prismatic platform frame or a circular platform frame, a central supporting component and a polygonal connector, wherein the polygonal prismatic platform frame comprises a plurality of equilateral polygonal components with side length being gradually increased, an outer inclined stay bar and an inner inclined stay bar from top to bottom; the polygonal connector is arranged on the inner side of the inner inclined stay bar and is fixedly connected with the inner inclined stay bar; and the central supporting component comprises a plurality of central connectors from top to bottom, horizontal supporting rods in uniform outward radial connection with the central connectors and central vertical columns connected with the central connectors from top to bottom. The basalt fiber cay ecological restoration multi-dimensional reef has the advantages of environment friendliness, high strength, long service life, corrosion resistance, plant modular production, short construction cycle, strong storm resistance, construction and mounting under various complex cay geological environments, benefit in coral apposition growth and capability of effectively repairing marine ecological environments.

Description

technical field [0001] The invention mainly relates to the field of marine engineering, relates to an artificial reef body, in particular to a coral reef ecological restoration multi-dimensional reef body made of basalt fibers. Background technique [0002] The phenomenon of coral reef degradation and death has occurred both at home and abroad. The death of coral reefs in some sea areas has affected the marine ecosystem. The food chain around coral reefs has been broken, marine life has declined sharply, some sea areas have become seagrass beds, and individual sea areas have become fishless. caught. The reasons for the death of coral reefs include: rising ocean temperature, pests and diseases, starfish with long thorns, artificial poaching of corals, extensive fishing of coral reef fish, snails, shellfish, ginseng and other benthic animals and herbivores. In the Xisha sea area, it was also found that new small corals attached and grew on the three-dimensional skeleton of de...

AI Technical Summary

Problems solved by technology

[0003] Traditional marine ecological restoration mostly uses shipwrecks, steel structure reefs, and artificial reinforced concrete reef structures; although artificial reefs with steel structures are conducive to coral attachment and growth in the short term, they will collapse after 3 to 5 years due to seawater corrosion and welding points falling off The reinforced concrete reef structure is not conducive to coral attachment for about 2 years, because the artificial reinforced concrete reef body chemically reacts with seawater to release alkaline substances, local pollution of seawater is not conducive to coral attachment, and the internal steel bars are rusted into powder in seawater Losing the function of reinforcing ribs, under the action of strong typhoon, the concrete of the entire reinforced reef body pulverized and fell off, and even caused collapse. As a result, no marine organisms and corals attached to the reef body after the artificial reinforced concrete reef body was put in for about two years, and the skeleton of the coral reef body could not At the same time, it is not conducive to the attachment and growth of other marine organisms, destroying the marine ecological environment within a certain period of time, and failing to achieve the purpose of marine ecological restoration in the short term

[0004] Furthermore, both the traditional reinforced concrete reef and the artificial reef with pure steel structure have no fixed system, and the reef is easy to roll over after strong typhoon or wave impact, and even the whole reef is washed away. Therefore, the traditional reinforced concrete reef Artificial reefs with pure steel structure cannot be fixed on the seabed for a long time

Although the sunken ship method is effective in forming artificial reefs, the number is small and it is difficult to form a scale effect. Large-scale corrosion of steel sunken ships may even pollute the marine environment
