Description
Technical field
The invention discloses a kind of preparation methods of artificial marine habitat, belong to marine environmental protection technical field.
Background technique
Artificial marine habitat is the seabed deposit luring fish collection into, inhabiting manually being arranged.Artificial marine habitat generally has brighter
Aobvious fish-gathering effect, the time that fish can be made to be stranded in reef area extend, and fishing ground expands, and is proliferated fish.It has been found that collection
Fish and cultivation effect preferably have the dwelling property rocky fishes surely such as flounder, flounder class, porgy class and grouper, black Jun, Greenling.Floating fish reef
There is good action to tuna, oceanic bonito, bamboo fish etc. is trapped.The fishing operation utilization rate and catch of artificial fish reef area may be generally higher than
Sea area around it, some catch can be multiplied.The effect of shallow sea proliferation reef is also obviously stablized.
The reason of artificial marine habitat fish gathering, is largely to adhere on reef, multiply shell-fish, shellfish, po-lychaete larvae etc. a variety of
Biology can trap fish forage.And the Complex Flow Status such as ascending current, vortex that fish shelter is formed then can be by seabed nutritive salt and deposition
Organic matter bring into, upper layer, increase the fertile degree in waters, promote the flourish of food organisms, further attract fish collection
Knot.Some fish collect to artificial marine habitat trip, inhabit, related with its inborn thigmotaxis etc..
Artificial marine habitat can be divided into the fish of the production such as stone, concrete, tire, glass reinforced plastic, steel by different manufacture materials
Reef；The large-scale assembling fish of the square bodily form, polyhedron shape, taper, cylindrical shape, semicircle etc. and various shapes can be divided by shape
Reef；Fishery harvesting type (most important), protection type, cultivation type, induction type fish shelter and shallow sea proliferation reef etc. can be divided by construction purpose.Also
It is ascending to be divided into plain edition, large-scale fish shelter, artificial reef fishing ground and sea area reef by construction scale.
Artificial marine habitat is built with concrete with series of advantages, it is each that concrete material can prepare various shapes, specification
It is different, structure is complicated, the Artificial Fish reefs of good appearance.However portland cement concrete alkalinity is strong, pH value is typically larger than 12.7, and
The pH value of seawater is about 8.3.Due to the continuous dissolution of calcium hydroxide in the seawater in concrete, lead to reefs surface and nearby sea
Water pH value increases significantly, and this strong alkaline condition has damaging effect to the incubation of common marine organisms.And existing concrete is anti-
Aqueous energy is poor, is easy by salt corrosion in seawater.
Carried out the construction of artificial marine habitat extensively both at home and abroad, in recent years to large volume, macroscopic void rate, structure is complicated
Direction develop.The reefball foundation in the U.S. is developed a kind of artificial marine habitat shaped like " chicken coop ", and is possessed entitled
The patent of reefball.But this artificial marine habitat is made of normal concrete, and a large amount of cement are not only expended in production process, right
It reduces production cost and production energy consumption is unfavorable, and natural environment can also be adversely affected using natural sand stone aggregate.It is public
It opens patent and describes a kind of method for manufacturing the low alkalinity gel material of concrete artificial reef, it is characterized in that utilizing blast furnace
The raw materials such as water-granulated slag, flyash, clinker, are milled down to certain specific surface area, obtain for manufacturing the low of concrete artificial reef
Alkalinity gel material.Though the solid waste used in the patent can reduce production cost, they are all ordinary cement coagulations
Common solid waste in soil.In addition river sand, sea sand, limestone gravel are used in the patent as aggregate, solid waste
Object utilization rate is lower, and the limited strength of resulting Artificial fish reef concrete, it is impossible to be used in preparation large volume, macroscopic void rate and
Complicated artificial marine habitat.Separately there is publication to describe a kind of fish reef cementing material containing nano-tailings and its manufacturer
Method, dosage of the clinker in cementitious material is still larger in this method, and the intensity for the concrete prepared 30~
60MPa or so.The strength level of two patents is also not suitable for preparation low cost, large volume, macroscopic void rate and complicated people
Work fish shelter.
Therefore, it is good to invent a kind of waterproof performance, is not easy by salt corrosion artificial marine habitat in seawater to marine environmental protection skill
Art field is necessary.
Summary of the invention
Present invention mainly solves the technical issues of, for normal concrete Artificial Fish firewood due to calcium hydroxide in the seawater
Constantly dissolution, causes reefs surface and neighbouring seawater in alkalinity, has damaging effect to the incubation of common marine organisms, and existing
There is concrete water-proof performance poor, is easy to provide a kind of preparation method of artificial marine habitat by the defect of salt corrosion in seawater.

The partial size of cement granules is small, and the gap that particle can be filled into cement granules and its aquation is formed improves plasticity state slurry and water
The microstructure of mudstone increases the resistance of fluid flowing so that the gap and aquation between cement granules, which form pore throat, becomes smaller
Power reduces fluid loss, and blocks the communicating passage that some aquations are formed, although having the duct of macroscopic view in concrete of the present invention
Structure, but the non-aperture sections of microcosmic upper concrete are fine and close, thus the performance that prevents water penetration of concrete improves, it is with high salt
Metals in Environments ion is difficult to demulsifying phenomenon of saltouing by concrete, improves the application of Artificial Fish firewood in the seawater
Energy；
(2) protective agent in waterproof duct of the invention is phenol-formaldehyde resin modified, wherein addition brightness molybdenum mountain flour and atoleine, brightness molybdenum
The a large amount of element sulphurs of Shi Zhonghan, sulfur-containing compound can make atoleine and phenolic resin generate crosslinked action, make waterproofing protection agent
The compactness of surface protection film paraffin layer is improved, and the primary raw material of waterproofing protection agent is phenolic resin, it is difficult to through fine and close
Paraffin-protected film water suction, and phenolic resin have preferable insulating properties, it is not soluble in water, it is steady in weak acid and weak base environment flowering structure
Fixed, Artificial Fish firewood, for amino modified dose, by the silica functional amido of concrete surface, makes dioxy with polyethyleneimine
SiClx and phenolic resin can dehydrating condensation, bonding is integral, and by the hydrogen bond that there is combination in inside improve waterproofing protection agent with
The binding force of silica, the silicone hydroxyl that silica generates are influenced that dehydration condensation can occur by the electronegativity of lye, are subtracted
The content of few surface hydrophilicity hydroxyl, improves waterproofing protection agent waterproof performance, and Artificial Fish firewood of the invention is caused by microstructure
Close celluar concrete is substrate, and the duct on surface and internal macroscopic view is covered by waterproofing protection agent, forms high-specific surface area
Artificial Fish firewood, by surface fixation seaweed, the sticky trehalose of seaweed secretion is stored in macroscopical duct of artificial marine habitat, favorably
In the fixation growth of more seaweed bios, attracts the fish of surrounding, have a extensive future.
