Abstract

The invention relates to an ecological breakwater technology, in particular to a waste concrete marine ecological engineering construction method, and belongs to the field of marine ecological engineering. The method comprises the steps that (1) the sea area where a breakwater is built is investigated; (2) a concrete attachment substrate is prepared; (3) seed oysters are collected quantitatively and farmed; (4) the surface of a waste concrete block is treated; (5) the waste concrete block is placed; (6) the oyster attachment substrate is placed on site; and (7) larva attachment monitoring andmanagement are performed. According to the method, blocks of building waste generated by buildings, infrastructures, etc. are utilized to build marine ecological breakwaters, the waste concrete can befully utilized in accordance with the characteristics of recycling and energy saving of the waste, the oyster attachment substrate can be further induced to grow, the water body is purified, shore-line erosion is prevented, biodiversity is maintained, carbon sequestration is achieved, ocean acidification is slowed down, and an ecological restoration ability is achieved.

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 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 certainly bring greater disa...
