Problems solved by technology

[0004] According to relevant research results, due to the differences in the crystallization state and molecular structure of different fish reef materials, they have different corrosion resistance in seawater, which determines their benefit years after they are put into use, and will also affect The economic benefits brought by it have a great impact, and the effects of different structural types of reefs are different

Abstract

The invention discloses a novel shell-based concrete fish shelter, and belongs to the field of marine environment restoration device. A preparation process of the fish shelter comprises the steps of preparing coarse broken shells, preparing shell powder and preparing the concrete fish shelter; according to the preparation process, the concrete fish shelter is prepared by adopting the discarded shells to replace natural sand and partial cement as main materials, the resources are recycled, the environmental protection is facilitated, the prepared fish shelter is high in fracture toughness and stability and good in hydrodynamic performance, and the structure of the prepared fish shelter can improve the distribution of nutrients in seawater.

Description

technical field [0001] The invention belongs to the field of marine environment restoration devices, and in particular relates to a novel shell-based concrete fish reef. Background technique [0002] As we all know, a large number of shells are piled up in some seasides, and a considerable amount of shells are also discarded in the seafood processing factories and household garbage in coastal cities. Taking the Shengsi sea area of ​​Zhoushan City as an example, the shells produced every year are about one-fifth of the annual household garbage pile. One, the quantity is about 90,000 tons. These shells will be transported to designated landfills for landfill disposal, which will bring huge economic burden to the city. On the other hand, making concrete according to the traditional method consumes about 70% sand and gravel by weight. In order to obtain these sand and stones, mountain collapse mining and river channel excavation are often carried out, which destroys the natura...
