Embodiment Construction

[0021] Below in conjunction with example the present invention will be further described.

[0022] How to make oyster shell fragments

[0023] Remove the oyster meat remaining in the oyster shell and remove the dirt on the surface of the oyster shell. The cleaned oyster shells are crushed, and after the crushed oyster shells are washed again, they are sequentially passed through mesh screens with apertures of 20 and 10 mm, and the fragments of oyster shells of 10-20 mm are boxed for preservation.

[0024] Fabrication of new reef modules

[0025] According to the proportion of cement, stones, oyster shell fragments, sand and water in the ratio of 336:952:106:640:185 kg / m3, weigh 1134g of cement, 3213g of stones, 358g of oyster shell fragments, 2160g of sand and 624g of water. is ±1%. Mix the above materials before pouring, and the pouring time should not exceed 15 minutes. The module is made by manual tamping, and the concrete mixture should be loaded into the mold in two l...

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 ...
