Method for making artificial fishing reef

Abstract

The invention discloses a method for making an artificial fishing reef, comprising the following steps: S1, stirring and mixing cement, an admixture, an additive and water in a specific proportion evenly, then adding a chemical foaming agent, stirring and mixing; S2, pouring a semi-finished product obtained in S1 into a mold for moulding, waiting for foaming, and then curing for a required periodafter demoulding; S3, punching the semi-finished product obtained from S2, thus obtaining the artificial fishing reef. By using the simple and feasible preparation method, the prepared finished product has a larger surface area, internal and external micro-holes and lower self-weight through the selection of raw materials, chemical foaming and punching treatment, being conducive to the habitat, reproduction and growth of fish and other marine organisms, conducive to the increase of biological density, and conducive to the efficient use of marine resources.

Description

technical field [0001] The invention relates to the field of artificial fish reefs, in particular to a method for making artificial fish reefs. Background technique [0002] Granite powder is the powder waste generated during the cutting process of granite. In the slate industry area, a large amount of granite powder waste cannot be disposed of in time, and a large amount of granite powder will occupy land due to long-term accumulation. Moreover, the granite powder is fine in texture and difficult to handle. It is easy to fly all over the ground in strong winds, and it will flow into rivers with rainwater in rainy days, which will not only pollute the environment but also cause great harm to the human body. [0003] A natural fish reef is a kind of reef formed by accumulation of fish bones or waste discharged by fish over many years. The rough surface of the reef formed by long-term accumulation in nature is suitable for the attachment of fish eggs, thereby protecting the ...

AI Technical Summary

Problems solved by technology

[0005] The existing artificial fish reef prepared by pouring concrete, on the one hand, its smooth surface is not conducive to the adhesion of fish eggs, the adhered fish eggs cannot be effectively protected, the survival rate is low, and the productivity needs to be improved; on the other hand, its density About 2500Kg / m 3 ,The weight of a single unit is as high as several tons or even dozens of tons, which is not conducive to transportation and delivery, high manpower, material and financial resources, long operation time and low efficiency
