A device and method for coral seabed cultivation suitable for strong sea conditions

Abstract

The invention discloses a coral seabed cultivation device and method suitable for strong sea conditions, and is used for the seabed cultivation of coral fragments and massive coral fragments. It is composed of coral attachment base, opening, base and vertical pipe pile. The hemispherical structure makes the wave force acting on the device in any direction point to the center of the circle, and does not generate an overturning moment on the whole device. The foundation stress is basically evenly distributed, and the anti-sliding stability is good. The porous network pattern ensures that corals are not affected by sediment deposition, and the photosynthesis of symbiotic algae is good. Under the action of the wave force, the hollow vertical pipe pile makes the seabed subbed soil fill up the interior of the pipe pile, making the device more stable. The present invention adopts glass fiber reinforced plastic material to be integrally molded at one time, has excellent manufacturability, low cost, small buoyant weight, is convenient for divers to arrange and place, and has significant economical efficiency. It is suitable for coral seabed cultivation under strong sea conditions, and has very important ecological value and practical significance .

Description

technical field [0001] The invention relates to the field of marine ecological restoration, in particular to a coral seabed cultivation device and method suitable for strong sea conditions. Background technique [0002] The coral reef ecosystem is an integral part of the marine ecosystem and is recognized as one of the ecosystems with high biodiversity and high productivity in the world. As a "tropical rainforest in the ocean", it not only provides habitat for marine life It is also of great significance to the protection of the coast and tourism. In recent years, with the acceleration of industrialization, climate warming, environmental pollution, over-exploitation of coral reefs and illegal mining, etc. have led to massive bleaching and death of corals around the world. The integrity and coverage of coral resources worldwide are declining sharply. Anthropogenic restoration of coral reef ecosystems. [0003] Coral cultivation has been carried out in foreign countries earl...

AI Technical Summary

Problems solved by technology

[0004] Among the many published technical patents at present, the cultivation device has a complex structure and high cost, which is not suitable for large-scale production and large-scale layout. It is difficult to install underwater and often requires a large underwater workload, and the structure cannot withstand the impact of typhoons. With the attack of waves, the stability is not good, and it is not suitable for my country's sea areas affected by the strong ocean dynamic environment. A typhoon can cause years of cultivation achievements to be wiped out, causing irreparable losses
