Abstract:
1. A corrosion protection system for a stay cable construction, said stay cable construction including a multiplicity of tension members, each tension member comprising: parallel steel tensile elements, said tensile elements extending between a first anchorage and a second anchorage and comprising a first end and an opposite second end, the first end co-operating with the first anchorage and the second end co-operating with the second anchorage, the corrosion protection system including tensile elements which are not provided with a permanent corrosion protection during their fabrication, wherein the corrosion protection system further includes: wherein the first anchorage of each tension member is situated in a first anchorage guide, and the second anchorage of each tension member is situated in a second anchorage guide and wherein: each second anchorage guide is connected to a dry air supply pipe and to the stay pipe which surrounds the connected tension member, wherein the connections are achieved in such a manner that the air injected in the second anchorage guide can form a dry airflow along the tension member in the stay pipe, and each first anchorage guide is connected to a stay pipe which surrounds the tension member with which it is connected, and wherein the first anchorage guide includes a first dry air outlet, through which dry air can escape.
