It is arranged at the interface of river and seawater, its innovative point is, seawater side surface and steel reinforced concrete knot on the steel and concrete structure plate
The side surface of structure plate seawater one is coated with corrosion-resistant coating, and the corrosion-resistant coating composition proportion is：Part by weight 88%~
92% epoxy resin, the 7%~8% of part by weight nickel powder, part by weight 1%~2% chromium carbide, the 0.5% of part by weight
~1% molybdenum powder, the 0.1%~0.5% of part by weight silicon, part by weight 0.2%~0.6% manganese, part by weight 0.1%~
0.9% tungsten.
Preferably, the corrosion-resistant coating optimal components proportioning is：The epoxy resin of part by weight 89%, part by weight
8% nickel powder, part by weight 1% chromium carbide, part by weight 0.5% molybdenum powder, part by weight 0.5% silicon, weight
The manganese of the 0.5% of ratio, the 0.5% of part by weight tungsten.
Preferably, the anhydrous calcium sulphoaluminate mineral of armored concrete consumption 8%~12% are added with the steel and concrete structure plate.
Preferably, the anhydrite of armored concrete consumption 6%~10% is added with the steel and concrete structure plate.

The advantage of the invention is that：Corrosion resistance is provided with surface by the seawater side on the above-mentioned steel and concrete structure plate
Coating, during being lifted on steel and concrete structure plate, plays a part of to prevent seawater to its surface corrosion.
It is in addition the ability of the anti-seawater corrosion of entirety of enhancing steel and concrete structure plate, anhydrous sulphur aluminium is added in steel and concrete structure plate
Sour calcium mineral, anhydrite, calcined diatomite, natural volcanic ash, silica flour, using the ability of their anti-seawater corrosions, the steel for being
The service life of mixed structural slab is improved.
Specific embodiment
Checkdam dam facing of the invention is mainly steel and concrete structure plate, and the underrun hinged-support of the steel and concrete structure plate is hinged on
On horizontal base below steel and concrete structure plate, steel and concrete structure close to vertical state is lifted around hinged-support by way of hinge-type
Plate causes that steel and concrete structure plate falls after rise and is the level of state to horizontal base.During installation settings, set by by steel and concrete structure plate
It is placed at the interface of river and seawater, if high tide, adjustment steel and concrete structure plate intercepts seawater and enter close to vertical state
River side, now the steel and concrete structure plate of seawater side, will soak in the seawater.To reduce corruption of the seawater to steel and concrete structure plate
Erosion, improves the service life of steel and concrete structure plate, and corrosion-resistant coating is coated with the side surface of steel and concrete structure plate seawater one.The corrosion resistant
Corrosion coating composition is matched：The epoxy resin of part by weight 88%~92%, the 7%~8% of part by weight nickel powder, part by weight
1%~2% chromium carbide, part by weight 0.5%~1% molybdenum powder, part by weight 0.1%~0.5% silicon, part by weight
0.2%~0.6% manganese, the 0.1%~0.9% of part by weight tungsten.
Nickel powder main component is nickel element, and nickel element can dissolve in the alloying elements such as the chromium with corrosion-resistance characteristics, molybdenum, is utilized
Dissolve in the ability that the chromium in nickel element improves corrosion-resistant coating corrosion resistance and pitting corrosion resistant performance in the corrosive mediums such as seawater.
Molybdenum element can improve passivation ability of the corrosion-resistant coating in the corrosive mediums such as seawater, make the passive state of corrosion-resistant coating steady
Qualitative and pitting corrosion resistant performance is greatly improved, and it is brilliant to significantly improve the resistance to local corrosion and resistance to chloride of corrosion-resistant coating
Between corrode performance.The effect of tungsten carbide is to improve the anti intercrystalline corrosion performance of corrosion-resistant coating and improve corrosion resistance to apply
The anti-erosion property of layer.
Practical effect shows that corrosion-resistant coating optimal components proportioning is：The epoxy resin of part by weight 89%, weight
The nickel powder of the 8% of amount ratio, the 1% of part by weight chromium carbide, part by weight 0.5% molybdenum powder, the 0.5% of part by weight
Silicon, part by weight 0.5% manganese, part by weight 0.5% tungsten.
It is reinforced concrete structure additionally, due to steel and concrete structure plate, when sea water intrusion is met with, steel reinforced concrete knot can be largely effected on
The service life of structure plate, considers to add the anhydrous calcium sulphoaluminate of armored concrete consumption 8%~12% in bar construction plate for this
Mineral, the anhydrite of armored concrete consumption 6%~10%, the calcined diatomite of armored concrete consumption 6%~10%, reinforced concrete
The natural volcanic ash of native consumption 6%~10%, the silica flour of armored concrete consumption 20%~30%.
The anhydrous calcium sulphoaluminate mineral of armored concrete consumption 8%~12%, anhydrous sulphur aluminic acid are added in bar construction plate
There is microdilatancy to act on for calcium mineral, anhydrite, and compensating concrete shrinks and reduces or remits crack, improve ion penetration resistance of concrete
Energy；Calcined diatomite, natural volcanic ash fill concrete slit, improve concrete density, prevent etching medium from entering mixed
