Combined glass fiber rib reinforced concrete artificial fish reef, control method and application

Abstract

The invention belongs to the technical field of artificial fish reefs, and discloses a combined glass fiber rib reinforced concrete artificial fish reef, a control method and an application. Open grooves are formed in the left side, the right side and the center of a main cross rod, and vertical rotating rods are clamped in the open grooves in the two sides; the open grooves in the two sides are tangent to a cylinder, clamping blocks are mounted on the periphery of the cylinder, and the main cross rod is connected with an auxiliary cross rod through concave-convex meshing grooves; and GFRP ribs are arranged on the main cross rod, the vertical rotating rods and the auxiliary cross rod, a concrete protection layer with the thickness of at least 15 mm is arranged outside the GFRP ribs, and the clamping blocks and plug pins are glass fiber composite boards. A large hollow space body is formed by assembling a plurality of small-size rod pieces, the rod pieces can be prefabricated in a factory and then transported to a related sea site to be assembled and put, and the transportation and putting cost is reduced. The artificial fish reef has better durability, and the service life of the artificial fish reef can be prolonged. Compared with the prior art, the artificial fish reef has great advantages in the aspects of cost, durability, flexibility, fish gathering capacity and the like.

Description

technical field [0001] The invention belongs to the technical field of artificial fish reefs, and in particular relates to a combined glass fiber reinforced concrete artificial fish reef, a control method and an application thereof. Background technique [0002] At present, China's sea area is vast, with many islands and reefs, with good natural sea ecological environment conditions and rich aquatic biological resources. However, with the rapid growth of my country's population, rapid economic and social development, environmental pollution, engineering construction and overfishing, my country's offshore fishery resources have seriously declined, the ecological environment of waters has deteriorated, and desertification of waters has become increasingly obvious, seriously affecting my country's marine biological resources. sustainable use. The State Council and the Ministry of Agriculture have successively issued various policies on artificial reefs and marine ranching to pr...

AI Technical Summary

Problems solved by technology

However, the cast-in-place reinforced concrete artificial fish reef is large in size, low in transportation efficiency, and high in cost, and the steel bars have serious corrosion problems in seawater environments.

[0004] Through the above analysis, the problems and defects of the existing technology are: cast-in-place reinforced concrete artificial reefs are large in size, low in transportation efficiency, high in cost, and there are serious corrosion problems of steel bars in seawater environments

[0005] The difficulties in solving the above problems and defects are as follows: first, the flow field effect of artificial fish reef depends on the ratio of reef body height to water depth, and the effect is not obvious when the ratio i
