In a suspension bridge structure, a main cable is used as an important stressed structure in the suspension bridge structure, the service life of the suspension bridge is directly influenced, and the main cable is generally required to be coated, protected, dehumidified and anti-corrosive so as to be completely and stably operated.
After the main cables are installed on the cable clamps, the coating protection is to coat the outer surfaces of the main cables, which are positioned between the adjacent cable clamps and exposed to the external environment, with a coating so as to realize the sealing and waterproof functions. For example, the applied coating may be a paint layer. Or, the main cables between the adjacent cable clamps can be wound with the winding steel wires, and then the winding steel wires are wrapped by the winding belt, so that the main cables between the adjacent cable clamps are prevented from being directly exposed to the external environment and corroded by rainwater.
The dehumidification anticorrosion measure is generally a method of conveying dry air to the inner space of the main cable through a dehumidification system. In order to ensure smooth circulation of the dry air in the main cable, it is necessary to ensure reliable sealing between the main cable and the cable clamp connected to the main cable.
Therefore, the sealability of the main cable between adjacent cable clamps has a significant influence on the maintenance of the main cable.
However, to the adoption twine the winding steel wire on the main push-towing rope between adjacent cable clamp, the reuse twines the protection mode that the band will twine the steel wire parcel and live, because the suspension bridge main push-towing rope is in complicated outdoor environment for a long time, long-term solarization and rain, operational environment is relatively poor, and the main push-towing rope can constantly vibrate in the high altitude, just so make the winding steel wire that twines on the main push-towing rope between adjacent cable clamp drop with twining the band easily, make the main push-towing rope between the adjacent cable clamp directly expose in external environment, lead to the main push-towing rope to be corroded by the rainwater, influence main push-towing rope life.

Optionally, the cable clamp is a unitary casting. The integral casting refers to a component which is integrally formed by casting, wherein the casting refers to a forming method for pouring molten metal into a casting mold and obtaining a metal part blank with certain shape, size and performance after solidification. The cast component can achieve the purpose of no machining or little machining, so that the manufacturing cost is reduced, and the machining efficiency is improved. The cable clamp is integrally cast, field assembly and assembly are not needed, the rigidity is good, and the use is convenient.
The above description is meant to be illustrative of the principles of the present disclosure and not to be taken in a limiting sense, and any modifications, equivalents, improvements and the like that are within the spirit and scope of the present disclosure are intended to be included therein.
