Background technique
Drag-line is the main bearing carrier of suspension cable bridge, once failure, bridge, that is, unusable.The master of suspension cable at present
Wanting disease is the corrosion at anchorage position, and the corrosion of anchorage will cause suspension cable to fail, and endanger the safe handling of bridge.
Traditionally mainly by cable guide pipe setting rain cover suitable for reading and rubber ring, which is arranged, prevents rainwater from entering cable guide pipe
And corrode anchorage.It finds in actual use, due to drag-line unavoidable eccentricity issues during the installation process, makes in waterproof cover
Rubber ring can not be fitted closely and be failed, and rainwater enters cable guide pipe along the gap of eccentric part.It is being used additionally, due to rubber ring
After a period of time, since the factors such as difference variation and solarization cause aging, the rubber ring after aging further fails.It may be said that mesh
Preceding waterproof cover measure be in actual use it is invalid, it is existing all to there is infiltration in current almost all of Stay Cable Anchors position
As.And dragline anchorage is caused to be corroded.
Some new methods have been used on some cable-stayed bridges at present, one is rain cover is suitable for reading and drag-line PE sheath it
Between weld PE sealing cap, although this method have certain waterproof effect, hot melt is reheated to PE, accelerates PE
Aging ultimately causes sheath failure, will cause the more serious consequences such as steel wire corrosion instead.The second is in rain cover installation suitable for reading
Stainless steel cylinder and air bag carry out sealing, and this method has been proved to highly effective at present, but structure is more complex, installation steps
More, the duration is longer.
