Manufacturing method for constructing novel artificial fish reef by using low-carbon environment-friendly material

Abstract

The invention relates to a manufacturing method for constructing a novel artificial fish reef by using a low-carbon environment-friendly material. According to the invention, oyster shells are crushed; cement, stones, the oyster shell pieces, sand and water are mixed according to a ratio of 336:952:106:640:185kg / per cubic meter. The materials are stirred, and a block is obtained; and the block is manufactured into the artificial fish reef. With prior arts, single reef weight is low, and can be easily flushed apart in sea areas with high current flow rate; and pollution is caused to sea area environment when a net cover is broken, such that application limitation exists. According to the invention, oyster shells are common solid waste at seaside, and are convenient to collect. Also, the cost is low. On a basis that load bearing strength is not influenced, concrete cost can be effectively reduced, and the defect of secondary pollution caused by waste fish reef to the environment can be avoided. The fish reef can reach a C15 load bearing standard. Also, compared with a standard concrete fish reed, with the novel fish reef, organism attachment amount can be increased by more than 200%.

Description

technical field [0001] The invention relates to the field of marine environmental protection and the technical field of fishery infrastructure, in particular to a method for making a new type of artificial fish reef constructed with low-carbon environmental protection materials. Background technique [0002] Oyster is a famous and common shellfish in the world, and my country's oyster production ranks first in the world. At present, the development and utilization of oysters in my country is mainly to process their edible parts, and a large number of oyster shells are discarded as garbage. The residual organic matter in these discarded oyster shells rots and stinks during the long-term stacking process, endangering the lives of residents, and the oyster shells themselves have become solid waste, causing serious pollution to the environment. [0003] Artificial reef refers to an object with a certain physical structure that is artificially set up and suitable for the living ...

Problems solved by technology

It has been confirmed in the patent that the folded space formed by the oyster shell is conducive to the growth activities of sea cucumbers and the attachment and growth of natural fish bait, but this sea treasure reef is specifically designed for the growth of sea cucumbers, and the weight of the monomer is relatively light. The sea area with high flow velocity is easy to be washed away, and the broken net will cause pollution to the sea area environment, which has certain application limitations
