Anti-sedimentation trapezoid basalt grating oyster reef device

Abstract

The invention discloses an anti-sedimentation trapezoid basalt grating oyster reef device, and particularly relates to the technical field of artificial oyster reefs, the anti-sedimentation trapezoid basalt grating oyster reef device comprises an oyster reef body, the oyster reef body is trapezoid, the area of the trapezoid cross section is smaller than that of the bottom, and the four side faces of the oyster reef body are each provided with two triangular wing plates; the two triangular wing plates are distributed on the side faces of the oyster reef body in an up-down arrangement mode, the triangular wing plates on the two adjacent side faces are distributed on the vertical face in a staggered mode, and the periphery of the oyster reef body is covered with a layer of basalt grating. The basalt composite fibers and the basalt grating are combined with the trapezoidal oyster reef body, the overall strength can be improved, the overall weight can be reduced, the sedimentation depth of the whole device is reduced, the anti-sedimentation purpose is achieved, oyster breeding is directly conducted on the basalt grating, then the basalt grating is fixed to the reef body, and the overall structure is simple. The utilization rate and the surface adhesion rate of the young oysters can also be improved.

Description

technical field [0001] The invention relates to the technical field of artificial oyster reefs, in particular to an anti-subsidence trapezoidal basalt grid oyster reef device. Background technique [0002] Oysters are bivalve molluscs that live in aggregates, and like benthic organisms that grow on hard bottoms. Oyster reefs are reefs formed by the accumulation and growth of a large number of oysters, which play an important role in water purification, the composition of seabed habitats, and the stabilization of coastlines and substrates. In recent years, due to the intensification of engineering construction activities such as sea reclamation and land reclamation, the over-exploitation of wild oyster resources by humans has led to a sharp decline in the number of wild oysters, environmental pollution, and the acceleration of sediment deposition have accelerated the shrinkage or even extinction of oyster reef habitats, thus making oysters Reef ecosystems are under threat. ...

AI Technical Summary

Problems solved by technology

However, when the reinforced concrete reef is used to make oyster ecological reefs, brown rope and oyster shells are often used to grow seedlings and then fix them with the reef. This will cause a large number of oyster seedlings to die during the secondary transportation, and the survival rate will be greatly reduced.
