Prefab Cable Bridge

JDCC Cable Bridge, also known as suspension bridge or cable-stayed bridge, is a large-span special bridge structure composed of a core load-bearing system of main cables, suspenders and pylons, combined with stiffening girders and abutment foundations. As the mainstream form of modern long-span bridges, it differs from the stress mode of traditional beam bridges and truss bridges. The bridge efficiently transfers the deck load to pylons and foundations through the cable system, completely breaking through the span limitation of conventional bridges and adapting to ultra-long-span crossing scenarios. Strictly complying with domestic bridge design specifications and international BS and AASHTO engineering standards, it features scientific structural stress, light and beautiful appearance, and both practicality and landscape performance. Suitable for permanent traffic operation, it is widely used in traffic connection projects of complex terrains such as large rivers, bays, straits and mountain valleys, as well as urban landscape traffic and scenic spot sightseeing passage scenarios.
The core load-bearing cables of the product are made of high-strength galvanized parallel steel wire cables and steel strands, which have extremely high tensile strength, excellent toughness and strong fatigue resistance, and can withstand reciprocating vehicle loads and wind loads for a long time without relaxation and deformation. The pylons are cast or assembled with high-strength concrete or Q355 high-strength steel structure, featuring high rigidity and excellent compression and bending resistance. The foundation is designed with professional geotechnical engineering to ensure stable bearing capacity. The bridge deck stiffening girder is made of national standard high-strength structural steel with outstanding overall deformation and torsion resistance. All steel components adopt multiple anti-corrosion protection processes including hot-dip galvanizing and fluorocarbon finish paint. The cables are equipped with special anti-corrosion grease and PE protective sleeves to effectively isolate water vapor, salt spray, acid and alkali corrosion, adapting to extreme and complex working conditions such as coastal areas, high altitudes, strong winds and high humidity. Adopting refined factory prefabrication and on-site accurate hoisting and splicing throughout the process, key welds and cable tension are verified through non-destructive testing and dynamic commissioning, ensuring high overall construction accuracy and strong structural stability.
