An in-service marine breakwater ecological method

Abstract

The invention relates to an ecological technology of breakwaters, in particular to an ecological method of marine breakwaters in service, and belongs to the interdisciplinary field of marine sessile organisms and marine ecological engineering. The invention includes: (1) investigation of the sea area where the concrete structure is built; (2) preparation of the concrete attachment base. (3) Quantitative collection and cultivation of oyster seedlings. (4) Surface cleaning of breakwater; (5) Brushing and maintenance of paint; (6) On-site placement of oyster attachment base. (7) Monitor larval attachment. (8) Nutrient addition and management. The present invention clears and cleans the breakwater in service, and fixes the attachment base with oysters around it, so as to make dense oysters adhere to the breakwater in service more quickly, and utilizes the characteristics of oysters as ecological engineers and purification The function of improving the water body and improving the water area makes the service breakwater highly ecological, and realizes the goal of ecological breakwater and long-term service.

Description

technical field [0001] The invention relates to an ecological technology of breakwaters, in particular to an ecological method of marine breakwaters in service, and belongs to the interdisciplinary field of marine sessile organisms and marine ecological engineering. Background technique [0002] Due to the rapid development of coastal economy in recent decades without paying attention to environmental protection, it has caused large-scale destruction of coastal ecology, and has had a huge impact on the ecology and economy of my country's coast. At present, with the promulgation of a series of relevant national policies, my country's marine engineering construction will also usher in a peak period. At the same time, the large-scale construction of marine engineering and the breakwaters that ensure the stability of the surrounding sea area will further damage the already fragile ecosystem of the ocean. If proper protection of the ecological environment is not taken, it will ce...

Problems solved by technology

[0021] 5. The effect of roughness on the attachment of marine sessile larvae

However, due to the knowledge of related disciplines such as marine biology, marine microorganisms, marine chemistry, and marine concrete engineering materials and structures, the direction of the disciplines is very different, so that many problems are encountered in the cross-research, such as the cement-based materials mentioned above. Unclear water-cement ratio, unclear mechanism of oyster adhesion induced by calcium carbonate materials, too much calcium powder added to cement, poor durability of concrete, and the addition of bovine bone meal is prone to mildew, etc. There are too many problems

In addition, the current research idea of ​​inducing oyster attachment is more suitable for newly-built marine breakwaters. It is not feasible for concrete breakwaters in service, because it is impossible to demolish the project and rebuild to change the concrete substrate of the breakwater. Therefore, new methods are needed to solve the problem.
