Abstract
A corrosion protection system for bridge stay cables comprising the immersion of the bridge stay cables in a corrosive resistant liquid retained within a corresponding cable sheath to isolate the bridge stay cables from the surrounding atmosphere, a liquid flow control device corresponding to each cable sheath to selectively drain condensation or purge the corrosive resistant liquid from the respective cable sheaths and a liquid supply reservoir corresponding to each cable sheath to selectively feed the corrosive resistant liquid to and from the corresponding cable sheath in response to changes in the temperature in the surrounding atmosphere, the system having the unique capability of providing a verifiable corrosion protection system for the stay cables.
Claims20
A corrosion protection system for bridge stay cables of a cable-stayed bridge including at least one tower and a deck or superstructure and at least one bridge stay cable extending between the upper portion of the tower and the corresponding deck, the upper and lower portions of each said bridge stay cable are anchored to the tower and corresponding deck by an upper and lower anchor respectively, each said bridge stay cable and said corresponding upper anchor and lower anchor cooperatively form a bridge stay cable means, each said bridge stay cable comprises a bundle of cable strands disposed in space relationship relative to a corresponding outer cable sheath forming a cable liquid chamber receiving a corrosive resistant liquid isolating said bundle of cable strands from said corresponding outer cable sheath.
