Functional composite ecologic fishing rock and construction method thereof

Abstract

The invention relates to a functional composite ecologic fishing rock and a construction method thereof. The functional composite ecologic fishing rock comprises a reinforced concrete base and a concrete main body framework fixed on the reinforced concrete base, wherein a groove is formed in the bottom of the reinforced concrete base, a cuboid through slot is formed in the middle position of the reinforced concrete base in a penetrating manner, and the cuboid through slot and the reinforced concrete base form a structure in the shape like a Chinese character "Hui"; and a plurality of bait culture medium HDPE mesh cage substratums are mounted on the concrete main body framework, and natural shells / oysters are stuffed in the bait culture medium HDPE mesh cage substratums. The construction method comprises the steps of performing whole casting, and mounting the bait culture medium HDPE mesh cage substratums. Through the adoption of the functional composite ecologic fishing rock disclosedby the invention, the difficult problems that a conventional artificial fish reef difficultly overcomes the influence of large sea currents in sea floor, is poor in stability and is easy to knock overby strong sea currents are solved, the difficult problems that a conventional reef is poor in settling preventing properties and a main body structure is easy to sink in the sea floor are solved, andthe difficult problem that the conventional artificial fish reef is single in functions is solved.

Description

technical field [0001] The invention relates to the field of artificial reefs used in the fields of restoration of fishery resources and construction of marine pastures, in particular to a functional composite ecological reef and a construction method thereof. Background technique [0002] Artificial reefs are artificial reefs used to provide habitat, growth and reproduction for marine fish and other marine life. [0003] However, most of the existing artificial reefs are hollow frame structures. Although there are communication holes to allow currents to pass through the reef, it is difficult to overcome the influence of large currents on the seabed, and the stability is poor, and they are easily overturned by strong currents. The bases of artificial reefs are mostly simple frame structures without a stable and anti-subsidence base structure design. They are only suitable for some sea areas with relatively gentle and stable bases. Subsidence is prone to occur on seabeds tha...

Problems solved by technology

[0003] However, most of the existing artificial reefs are hollow frame structures. Although there are communication holes to allow the current to pass through the reef, it is difficult to overcome the influence of large currents on the seabed, and the stability is poor, and it is easy to be overturned by strong currents.

Most of the bases of artificial reefs are simple frame structures without a stable and anti-subsidence base structure design. They are only suitable for some sea areas with relatively gentle and stable bases. Subsidence is prone to occur on seabeds that are not flat enough or dominated by silt

Moreover, the existing reefs only simply use shellfish as the main species of biological multiplication, and their biological aggregation, multiplication function and biodiversity are relatively simple.
