Suspension bridge sling anti-corrosion method and structure
Provided is a suspension bridge sling anti-corrosion method and structure. The suspension bridge sling anti-corrosion structure comprises anchor heads at both ends of a sling and one end serves as an air inlet and the other end serves as an air outlet to form an air channel in the sling in series. The air inlet and the air outlet are connected to a monitoring box for monitoring the temperature, humidity and pressure of the air respectively and the two monitoring boxes are connected to an air source through valves. The air source can be clean dry air or inert gas. The suspension bridge sling anti-corrosion method includes the step that the inside of the anchor heads are filled with the clean dry air or the inert gas which both flow in gaps steel wires of the sling for actively preventing the steel wires of the sling and the anchor heads from being corrodes. The inside of the sling is filled with pressure air for preventing external corrosion substances from entering the sling. When a problem occurs on a sling protection layer, the air pressure change information is fed back through the monitoring boxes for providing guidance for the maintenance management. The suspension bridge sling anti-corrosion structure has the advantages of improving the corrosion resistance, prolonging the service life and reducing the maintenance cost of the sling.
