Description
Technical field
The invention belongs to building material technical field, and in particular to a kind of seabed artificial reef.
Background technology：
The 18 of party explicitly point out greatly, and it is national great strategy to build ocean power, and the development of marine economy be unable to do without ocean
The construction of engineering, the particularly offshore engineering on island and Hai Jiao away from mainland coastline.Due to the tidal bulge of seawater
The random navigation for being distributed to ship and the life of islander, the work of falling, island periphery bare rock and submerged reef bring all
More inconvenience, therefore on island and foundation engineering is quickly built and rushes to repair on Hai Jiao, for example, underwater submerged reef is quickly built up
Bare rock and bare rock build up basis implementation etc. engineering construction to accelerate ocean depths islands and reefs development and utilization have it is very heavy
The realistic meaning wanted.But traditional construction material currently on the market, such as：Cement, river sand, stone and fresh water etc. are for away from continent
For the island in coastline, transport, handling, storage and construction of these raw material etc. will become very difficult.Not only transport into
This is excessive, while under the marine environmental conditions away from mainland coastline, it is several to be particularly the work such as handling and the storage of raw material
It is difficult to try out, and traditional underwater construction technology also is difficult to adapt to the environmental condition of islands and reefs.Therefore a kind of be adapted to is researched and developed
In engineering material and the construction technology of simplicity that seabed artificial reef is quickly built in off-lying sea islands and reefs or coastline, to away from big
Engineering construction on the island and Hai Jiao of land-sea water front has highly important strategic importance.
The content of the invention：
It is a kind of suitable for quickly building artificial creation under the high-performance water of artificial reef in seabed it is an object of the invention to propose
Reef mortar, this underwater artificial creation reef mortar not only has good underwater anti-dispersibility, while setting time is fast, under water
24 it is small when compression strength can reach 5-30MPa, in addition this mortar later strength is quickly grown, and can reach 10- within 28 days
70MPa, due to the mortar excellent mobility and penetrating power, the seabed artificial reef formed after curing has with existing reef disk
There are engagement and cementitiousness well, finally can be built into a novel seabed artificial reef from seabed primary concreting to sea level
Disk.
Underwater artificial creation reef mortar proposed by the present invention, by cement, sulphate aluminium cement, mortar modifier, anti-dispersant,
Silicon ash, flyash, slag, aggregate and mixing water are formed, and the percentage by weight of each component is：
Its total amount meets 100%.
In the present invention, the cement is portland cement, Portland cement, slag cements, pulverized fuel ash cement or fire
It is one or more compound in the ash concrete of mountain.
In the present invention, the sulphate aluminium cement is in early-strength sulphate aluminium cement or high-strength sulphate aluminium cement
It is one or more compound.
In the present invention, the mortar modifier is acrylic acid, ethene and polyvinyl chloride copolymer, naphthalene sulfonic salt, poly- carboxylic
Hydrochlorate, it is one or more compound in melamine polymers.
In the present invention, the anti-dispersant is polyacrylamide.
In the present invention, the silicon ash is by the ultra-fine SiO that is formed during smelting duriron ore2Powder.
In the present invention, industrial residue that the flyash is discharged by coal-burning power plant, one kind of I grades of ashes or II grades of ashes.
In the present invention, the slag is levigate blast-furnace cinder.
In the present invention, the aggregate is sea sand, river sand, stone, and the polyphosphazene polymer of formation is expanded after dead coral reef and water suction
It is one or more compound in resin.
In the present invention, the mixing water is one kind of fresh water or natural sea-water.
The preparation method of the present invention can be divided into following 2 kinds：
1. Extemporaneous method：Raw material is accurately weighed in proportion, weighs cement first, sulphate aluminium cement, mortar modifier,
Silicon ash, flyash, slag and aggregate add mixer, after weigh seawater, add seawater while stirring, stir 5-10 minutes, stop
After machine 1-3 minutes, continue stirring 1-2 minutes, up to required product.
2. dry-mixed mortar method：Cement, sulphate aluminium cement, mortar modifier, anti-dispersant, silicon are accurately weighed in proportion
Ash, flyash, slag and aggregate, add dry-mixed mortar batch mixer, stir 5-10 minutes, dry blend are made, then according to certain
Specification carries out quantitative package, and packaging should have moisture-proof impervious effect.In use site, dry-mixed mortar and seawater are proportionally added into
In mixer, mixing 5-10 minute after, shutdown 1-3 minutes, if recipe requirements, then accurately weigh at the scene dead coral reef and
Polyphosphazene polymer resin after water suction etc. is added in mixer, continues stirring 3-5 minutes, up to required product.
The manufacturing process and construction technology of the present invention is easy, is suitable for large batch of production, transport and storage.
It is 5-30MPa that artificial creation reef mortar of the invention underwater detects the compression strength of 1 day through relevant department, the resistance to compression of 28 days
Intensity is 10-70MPa
The present invention has the advantage that：
1st, since the underwater artificial creation reef mortar of the present invention has good underwater anti-dispersibility, while also have fine
Underwater mobility, you can direct pouring molding under water, the seabed artificial reef formed after curing have with existing reef disk
Engagement and cementitiousness well.
2nd, since the seabed artificial reef of the present invention not only has higher early strength, (24 can reach 5-30MPa when small),
Later strength quickly grows and (can reach 10-70MPa within 28 days) at the same time, therefore available in seabed fast pouring seabed artificial reef.
3rd, due to the present invention underwater artificial creation reef mortar by using the macromolecule copolymer resin after water suction as people
Work aggregate, so as to change all using sandstone as the concrete making technology of aggregate in conventional concrete material, such as remote
Using this underwater artificial creation reef mortar in the islands and reefs engineering construction of mainland coastline, can not only save substantial amounts of sandstone transport,
Handling and storage charges are used, and then reduce the construction cost of engineering, while can provide one to lack the islands and reefs engineering construction of sandstone again
The construction technology of the new underwater quick rush construction of kind.
4th, due to present invention uses the flyash of large dosage and slag, therefore the manufacture cost of engineering can be significantly reduced.
5th, since the raw material of the present invention are all using the market finished product largely produced, so raw material are easy to get, it is adapted to wide
General application.
