Problems solved by technology

[0022] 5. The effect of roughness on the attachment of marine sessile larvae
This has brought huge challenges to the ecological restoration of breakwaters in underwater areas. It not only involves knowledge of related disciplines such as marine biology, marine microorganisms, marine chemistry, and marine concrete engineering materials and structures, but the direction of disciplines varies greatly.

Abstract

The invention relates to an ecological technology of breakwaters, in particular to an ecological restoration method for underwater areas of marine breakwaters in service, and belongs to the fields of marine engineering 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 breakwaters. (5) Underwater pouring of mortar; (6) On-site placement of oyster attachment base; (7) Monitoring of larvae attachment. (8) Nutrient addition and management. The present invention develops underwater non-dispersible ecological mortar and pours it in places where there are no oysters attached to the underwater area of ​​the breakwater to induce a large number of oysters to attach to the underwater area of ​​the breakwater. As an ecological engineer, oysters have the characteristics of purifying water bodies and improving water areas. In this way, the ecological restoration of the underwater area of ​​the breakwater can be realized, and the ocean breakwater can be fully ecologicalized.

Description

technical field [0001] The invention relates to an ecological technology of breakwaters, in particular to an ecological restoration method for underwater areas of marine breakwaters in service, and belongs to the fields of marine engineering 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, ...
