ANTIRUST PROTECTION SYSTEM FOR STRUCTURES COMPRISING STAY ROPES Russian patent published in 2009 - IPC E01D19/16 E04C5/10 

FIELD: transport.

SUBSTANCE: antirust protection system for structures comprising stay ropes includes multiple assemblies operated under tension, each of which consists of parallel steel elements passing between the first and second anchor attachments and incorporates two opposite ends, the first and second ones. Note that the said first end interacts with the first anchor attachment, while the second one interacts with the second anchor attachment. The antirust protection system uses the tensions element not furnished with permanent antirust protection and called "unprotected elements operated under tension". The said system comprises multiple stay pipes enveloping the assembly operated under tension, each consisting of unprotected elements operated under tension. It includes also a drying device allowing producing air with the preset mean humidity content, that is, the so-called, "dry air", designed to feed dry air from the drying device into preset points, each arranged on one of three devices, namely, on the first anchor attachment, second anchor attachment and multiple stay pipes, a ventilation device to force dry air into the pipes from the said multiple dry air feed pipes and test, measurement and control appliances.

EFFECT: antirust protection system not increasing diameter of all operating elements operated under tension and making assembly to be operated under tension, continuous control of aforesaid system.
