The main accessories of the cable-stayed bridge and arch bridge include socket protection cover, rainproof cover, external damper, internal damper, stainless steel sheath, etc.
Rainproof device for end of cable girder, which adopts a novel stainless steel rainproof cover and a sealing cover device, effectively solve the girder end sealing protection problems. It has been applied in many large cable-stayed bridges in China, and the actual effect is remarkable. The technology has won the national invention patent.
External damper, the main products are external viscous dampers, external permanent magnetic rheological dampers, external electromagnetic rheological dampers, internal viscous dampers, and stay cables, eddy current dampers. The performance meets the Ministry of Communications Standard stay cable viscous damper (JT/T 1038-2016).
