Problems solved by technology

However, this approach is costly and is not conducive to large-scale delivery
Most of the reefs made of stones, concrete, waste ships and other materials are directly placed on the seabed, so that seaweed spores or other propagules (such as fertilized eggs, reproductive branches capable of vegetative reproduction, etc.) in seawater can naturally attach and grow. , but the progress of such methods to form algae fields is slow

Abstract

The invention relates to a bionic artificial algae reef and a construction method thereof. The method comprises the following steps: step 1, preparing a bionic ecological building material: preprocessing mud flat sludge; supporting an ordered mesoporous medium; performing drying; and performing compounding; step 2, welding a bionic artificial algae reef skeleton: according to a preset shape and size, welding the bionic artificial algae reef skeleton by using steel bars as materials; step 3, pouring concrete to the bionic artificial algae reef skeleton, performing drying, and performing shaping; and step 4, performing coating by a bionic ecological building material layer: adding 40-50% by mass of water into the bionic ecological building material prepared in the step 1, performing uniformstirring to form slurry, uniformly coating the outer surface of the bionic artificial alga reef shaped in the step 3 by the slurry, and performing natural air drying to obtain the bionic artificial algae reef.

Description

technical field [0001] The invention relates to a bionic facility in the ocean and a construction method thereof, in particular to a bionic artificial algae reef and a construction method thereof. Background technique [0002] As a kind of artificial fish reef, artificial algae reef is an underwater structure put in to improve the habitat of marine algae, proliferate and protect fishery resources. After the algae reef is placed, the exposed surface will absorb organisms and sediments, and start the succession process of the biological community. Depending on the conditions, generally a few months to a few years later, the reef will be attached to a large number of algae, shellfish, echinoderms, etc. Sessile and semi-sessile organisms such as animals. [0003] Seaweeds can only get the light and nutrients they need for growth and development stably after they are attached to reefs or other stable substrates. If the attachment is not firm, after detaching from the substrate,...
