Benefits of technology

[0029] This invention offers at least the following advantages: It significantly improves the quality and efficiency of spatial cable construction through innovative technological means. A unique wire arrangement rule combined with a real-time monitoring system fundamentally suppresses wire slippage. A phased catwalk sag compensation strategy effectively offsets the effects of load deformation, ensuring the cable strand shape always meets design requirements. A three-dimensional adjustment mechanism for the cable shoe completely solves the spatial deflection adaptation problem, guaranteeing smooth construction. An intelligent control system integrates multi-source information to achieve proactive protection under sudden environmental changes. The entire technology significantly reduces construction safety risks while also reducing material consumption and construction costs.

Abstract

The application discloses a construction method of a suspension bridge space cable AS method, and comprises the following steps: adopting a dead wire and live wire partition arrangement strategy; arranging steel wires in a saddle groove of a cable saddle according to a rule that the dead wires are in the middle and the live wires are on two sides, and arranging the steel wires in a strand shoe according to a rule that the dead wires are on the upper side and the live wires are on the lower side, and arranging the steel wires in a layered manner from the middle to the two sides; setting a sag control cable below a main cable former, controlling catwalk linearity in stages, adjusting the first layer of cable strands for more than or equal to 2 times during construction, and supporting subsequent cable strands by the formed cable strand rigidity; deploying an intelligent control system, integrating a GNSS positioning spinning wheel, a tension sensor and a visual identification module, and monitoring the position and tension of the steel wire in real time, and automatically slowing down or stopping when the steel wire is detected to be out of position or the tension is out of limit. The application significantly improves the construction quality and efficiency of the space cable.
