Problems solved by technology

[0025] The purpose of the present invention is mainly aimed at the problem that the expansion and repair of breakwaters will cause damage to coastal ecology, and the current situation that the marine sessile organisms on the surface of most marine concrete projects are not dense, and manual intervention is required
The present invention treats the surface of waste concrete through coating technology, and uses the treated waste concrete to build a new type of marine ecological project that attracts sessile organisms such as oysters. The resulting ecological benefits also solve the problem of difficult disposal of a large amount of waste concrete

Abstract

The invention relates to an ecological anti-wave lifting technology, in particular to a marine ecological engineering construction method of waste concrete, which belongs to the field of marine ecological engineering. The present invention includes: (1) sea area investigation of the location of breakwater construction. (2) Preparation of concrete attachment base. (3) Quantitative collection and cultivation of oyster seedlings. (4) Surface treatment of waste concrete blocks. (5) Place waste concrete blocks. (6) Place the oyster attachment base on site. (7) Monitor larval attachment and management. The present invention utilizes blocky construction waste generated by buildings and infrastructure to construct marine ecological breakwaters, which not only can make full use of waste concrete, meet the characteristics of waste recycling and energy saving, but also induce the growth of oyster attachment bases, purify water bodies, Preventing coastline erosion, maintaining biodiversity, sequestering carbon and slowing ocean acidification, with ecological restoration capabilities.

Description

technical field [0001] The invention relates to an ecological anti-wave lifting technology, in particular to a marine ecological engineering construction method of waste concrete, which belongs to the field of marine ecological engineering. Background technique [0002] Due to the rapid development of coastal economy in recent decades and the lack of attention to environmental protection, large-scale destruction of coastal ecology has been caused, and it has had a huge impact on the ecology and economy of my country's coastal areas. At present, with the introduction of a series of relevant national policies, my country's marine engineering construction will also usher in a peak period. At the same time, large-scale construction of marine engineering and breakwaters to ensure the stability of the surrounding sea areas will further damage the already fragile ecosystem of the ocean. If proper protection of the ecological environment is not taken, it will bring greater disaster ...
