Multilayered stereoscopic artificial fish shelter

Abstract

The invention discloses a multilayered stereoscopic artificial fish shelter. The multilayered stereoscopic artificial fish shelter comprises multiple layers of H-shaped components and a plurality of vertical prisms, wherein the multiple layers of H-shaped components are formed by connecting a plurality of horizontal cross beams; each vertical prism is vertically connected with the corresponding layer of H-shaped components, so that a hollowed-out multilayered stereoscopic fish shelter structure is formed; the horizontal cross beams and the vertical prisms are formed by FRP ribs and concrete byone-time pouring; tips of the FRP ribs are connected by gradually enlarged anchoring tips, so that the strength of anchoring between the FRP ribs and the concrete is enhanced. The multilayered stereoscopic artificial fish shelter not only has good stability in a marine complicated fluid environment, but also has large space accommodating ability, provides bounteous inhibiting space for foraging,reproduction, growth, development and the like for marine organisms, and meets requirements of reproduction and survival of a large number of various marine organisms, and therefore, effects of improving an offshore ecological environment and multiplying marine living resources are improved.

Description

technical field [0001] The invention relates to the field of breeding fishery engineering facilities, in particular to a multi-layer three-dimensional artificial fish reef. Background technique [0002] With the overfishing and development of the ocean by humans, the coastal environment is gradually deteriorating, the space for marine life to survive is getting smaller and smaller, and the coastal fishery resources are on the verge of collapse. People are paying more and more attention to the coastal environment and the recovery of offshore fishery resources. and protection, marine ranching, artificial reefs, etc. have gradually become research hotspots. [0003] Artificial reefs are artificial structures placed in natural waters to restore the ecological environment of waters. In order to create marine pastures, people have successively put various artificial reefs in the offshore to provide marine organisms with habitats such as feeding, reproduction, growth, and developm...

AI Technical Summary

Problems solved by technology

[0004] Some traditional small artificial reefs have no obvious deceleration effect on ocean currents. Therefore, at present, large prefabricated reinforced concrete artificial reefs with ocean current deceleration effects are widely used in vast sea areas, but in marine environments, seawater Chloride ions in the artificial fish reef will enter the interior of the artificial fish reef through the internal gaps in the concrete. Long-term use will cause corrosion to the steel bars. However, in some existing FRP concrete fish reefs, the alkaline environment of the concrete will also cause corrosion to the FRP bars, resulting in artificial fish The service life of the reef design base period is reduced, and the later maintenance costs are higher

In addition, most of the currently used artificial reefs are single-layer hollow polyhedrons made of concrete. The main problems of artificial reefs with this structure are: first, their stability is poor, and they are easy to roll under the impact of ocean currents or wind waves in multiple directions; Second, the space structure is narrow, unable to meet the needs of reproduction and survival of a large number of marine organisms
