Description
Technical field
The present invention relates to tidal range district, a kind of ocean and wave and spatter district's concrete component corrosion protection method, belong to the antiseptic project technical field.
Background technology
In recent years, the economic develop rapidly of China, infrastructure drop into and increase severely.Numerous concrete components have wherein been built.Concrete is widely used in Oversea bridge, the coastal engineering as a kind of nonmetals, and the corrosion in seawater is quite serious.The corrosion protection of concrete component has obtained those skilled in the art and has enough paid attention to; People have recognized that the concrete component corrosion of not doing any corrosion protection is very serious; Be difficult to reach the application life of design; Even some concrete component less than 10 years just by heavy corrosion, the overhaul of having to, the waste that expends a huge sum of money and resource.
Concrete component is in different corrosive environments in the ocean; Those skilled in the art generally are divided into marine atmosphere zone, wave from top to bottom with the marine corrosion environment and spatter district, tidal range district, district and 5 zones, ooze district under water; Existing research shows and is in that wave spatters the district and the concrete component corrosion rate in tidal range district is the fastest; Much larger than other zone, and the difficult problem that this regional corrosion protection method is the antiseptic project field always.
Be in wave and spatter the district and have much with the concrete component corrosion protection method in tidal range district, mainly contain increase thickness of concrete cover, add concrete corrosion resistant agent, coating protection is flooded, added to employing epoxy-coated reinforcement, silane and to the reinforcing bar electrochemical protection etc.Using now maximum is to add coating protection to defend the doctrine, promptly in the method for concrete external surface painting of coating.Its way generally is to adopt three coating structures anticorrosion, and bottom is an epoxy primer, and the intermediate layer is the epoxy intermediate coat, and surface layer adopts polyurethane finish or fluorine carbon finishing paint.This method is to continue to use the anti-corrosion method of steel member; Its anti-corrosion method, technology, coating member, coating type are all anticorrosion identical with the steel member; This method that adds coating protection is not taked corresponding processing according to concrete property; Though therefore certain antiseptic effect is arranged, shortcoming also clearly.At first, use and to add coating to antiseptic concrete, the adhesive power of its coating and concrete substrate is low, only has 1 ~ 3MPa, coating to be easy to come off and causes anticorrosion inefficacy; Secondly; This method complex technical process will accomplish whole coating application 4 ~ 7 road coating approximately, and per pass coating all needs just can descend 4 ~ 24 hours hardening times the road application; Therefore the application cycle very long, be difficult to construct to being in the engineering that wave spatters under district and the tidal range district environment; At last, the durability of paint coatings under marine environment is low, will thoroughly keep in repair its maintenance cost even more taller than application first in general 5 ~ 10 years.
Because never a good method solves the anticorrosion problem that wave spatters district and tidal range district concrete component; So still any preservative treatment is not done in this zone at present a lot of concrete component engineerings, its result will inevitably reduce the durability of concrete component greatly.
Summary of the invention
The present invention provides under a kind of marine environment wave to spatter district and tidal range district concrete component corrosion protection method; Has high-durability; Than anticorrosive paint coating marine growth guard shield is difficult to destroy simple to operate on workability, safe and efficient and site operation cycle weak point.
The technical scheme that the present invention addresses the above problem is following:

(2) apply one silane impregnating agent, silane impregnating agent consumption 300g/ ㎡, length of penetration is greater than 1mm;
(3) behind the surface of concrete structure natural air drying of silane coated impregnating agent, the Silante terminated polyether seal glue of blade coating one deck, thickness are 2 ~ 5mm;
(4) Silante terminated polyether seal glue coats prefabricated protective cover after applying and accomplishing immediately; Protective cover inner surface polish in advance roughening treatment and one fluid sealant of blade coating;
(5) two ends and corner use fluid sealant to seal processing about the guard shield;
(6) the whole weather resistant finish paint that applies of coating system;
