Problems solved by technology

However, when deploying artificial fish reefs on a large scale, the process of making brackets and cages around the concrete structure is cumbersome and wastes resources
In addition, the seawater corrosion of the steel structure support is very serious, and the HDPE material used as the cage is also relatively poor in aging resistance, resulting in a short durability life of the artificial fish reef
[0004] CN 104529286A discloses a new concrete artificial fish reef containing oyster shell powder, which is specifically made of the following raw materials: cement: sand: gravel: mixing water: oyster shell powder: powder ash: mineral powder The ratio is: 1:(1.9~2.6):(2.8~3.9):(0.4~0.6):(0.1~0.2):(0.1~0.3):(0.1~0.5); the preparation method is: add the above raw materials Concrete mixer, after mixing, put it on the vibrating table to vibrate and compact evenly, and remove the formwork after 12-24 hours; after removing the formwork, perform standard maintenance for 28 days. The oyster shells are mixed with concrete raw materials and poured into fish reefs, which do not have suitable roughness and bionicity, and still cannot obtain a good fish collection effect

Embodiment 2

[0027] Example 2 Preparation of fish reefs with cement mortar overlay without biological calcium carbonate and oyster shells:

[0028] (1) Take water, cement and sand, and mix them uniformly according to the mass ratio of 434:1085:1035 to obtain cement mortar;

[0029] (2) Sprinkle water to wet the surface of the fish reef substrate prepared in Example 1, apply cement mortar batches on the surface to form a cement slurry layer with a thickness of 25mm, and maintain it for 28 days to obtain final product.

Embodiment 3

[0030] Embodiment 3 Containing the cement mortar covering layer of 5% bio-calcium carbonate and the preparation of fish reefs not inlaid with oyster shells:

[0031] (1) High-pressure cook the discarded fish bones to remove residual protein and fat. After drying, mix them with the mass ratio of fish bones: eggshell: coral: shell = 1:1:1:1, and place them in a grinder Pulverize and sieve to obtain the biological calcium carbonate external admixture particles with a particle size of 180 mesh;

[0032] (2) Take water, cement and sand, mix them uniformly according to the mass ratio of 434:1085:1035, then add bio-calcium carbonate particles accounting for 5% of the cement mass, put them together in a mixer, stir at a high speed until uniform, and obtain a cement paste material;

[0033] (3) Sprinkle water to wet the surface of the fish reef substrate prepared in Example 1, apply cement slurry material batches on the surface to form a cement slurry layer with a thickness of 25 mm, a...

Embodiment 4

[0034] Embodiment 4 Containing the cement mortar covering layer of 8% bio-calcium carbonate and the preparation of fish reefs not inlaid with oyster shells:

[0035] (1) Get water, cement, sand, mix evenly by mass ratio 434:1085:1035, then add the biological calcium carbonate particle that makes by the method for embodiment 3, consumption is 8% of cement quality, put into the blender jointly, high-speed Stir until uniform to obtain cement slurry material;

[0036] (2) Sprinkle water to wet the surface of the fish reef substrate prepared in Example 1, apply the cement slurry material batches on the surface to form a cement slurry layer with a thickness of 25 mm, and maintain it for 28 days to obtain final product.

Abstract

The invention discloses a bionic concrete artificial fish reef arranged on the seafloor. According to the fish reef, C40 concrete is used for pouring to form an artificial fish reef base body, the surface of the base body is covered with a protective layer which is composed of cement mortar, biological calcium carbonate and oyster shells, the biological calcium carbonate is made of eggshells, corals, seashells and fishbone and is used as an additive to be added into the cement mortar, the cement mortar mixture is smeared on the surface of the fish reef base body to form cement paste after the biological calcium carbonate and the cement mortar are evenly stirred together, and the oyster shells are inlaid in the cement paste in a convex face outward mode. According to the artificial fish reef, the environment-friendly function, the durable function and the trapping function are integrated, the cement mortar covering layer doped with the biological calcium carbonate and the coating of the oyster shells can attract marine organisms to inhabit, and thus the trapping effect of the artificial fish reef can be better achieved; compared with a traditional concrete fish reef, the artificial fish reef has good waterproof property and chloride ion resistance, surface roughness and alkalinity of the surface of the fish reef are appropriate, bionic performance is achieved, and the fish collecting effect is excellent.

Description

technical field [0001] The invention relates to a novel ecological artificial fish reef material and a preparation method thereof, and belongs to the technical fields of artificial fish reef engineering for ocean restoration and fishery multiplication, harbor engineering and island reef engineering. Background technique [0002] Artificial reefs are mainly for the purpose of providing habitat, luring fish, and collecting fish. At present, reinforced concrete is mainly used as the main body of the artificial reef frame, and the durability is greatly challenged in the marine environment. It is very high, which is not conducive to the attachment and growth of marine organisms. [0003] CN2203860227U discloses a kind of bait cultivation type artificial fish reef aiming at the problem of improving the fish collecting ability of artificial fish reef. The shells are placed in the net cage, so that the fish collecting ability is improved. However, when artificial fish reefs are la...
