The utility model belongs to the technical field of the bridge, a heavy protective system bridge beam supports with graphite alkene zinc is waded to specific saying. Its technical scheme: including setting up the support body between bridge girders and pier, the external coating graphite alkene zinc that exposes of support body weighs the protective system, the heavy protective system from interior to exterior of graphite alkene zinc for modified graphite alkene zinc primer, coats with lacquer layer and the six / seven set of protective system finish paint layer on the railway in proper orderin the middle of lamella graphite alkene / cloud hoop oxygen. The bridge beam supports that should have the heavy protective system of graphite alkene zinc has that coating adhesive force is strong, the cathodic protection performance is good, the shielding strong and prevents the characteristics that corrosive effects is showing.
