Ballast inhaul cable structure and design method thereof
The invention relates to a ballasting inhaul cable structure, which comprises an inhaul cable, a plurality of connecting rods, a plurality of connecting rods, a plurality of connecting rods, a plurality of connecting rods and a plurality of connecting rods, wherein two ends of the inhaul cable are respectively anchored on a girder and a pier; the inhaul cable protection device comprises a pre-buried pipe and an inhaul cable limiting component arranged on the inner wall of the pre-buried pipe, the inhaul cable penetrates through the pre-buried pipe, and the contact face of the inhaul cable limiting component and the inhaul cable is an arc face; an embedded pipe of the inhaul cable protection device is arranged in the main beam and/or the bridge pier. The inhaul cable protection device is installed in the main beam and/or the bridge pier, the contact faces of the inhaul cable limiting components in the inhaul cable protection device and the inhaul cables are the arc faces, and even if the main beam generates longitudinal large displacement deformation and the inhaul cables generate longitudinal deformation at the anchoring position of the main beam or the anchoring position of the bridge pier, the inhaul cables can make contact with the corresponding inhaul cable limiting components; and a section of arc deformation is formed, so that the bending angle of the anchoring end is greatly reduced, the adverse effects of fatigue damage on the safety and durability of the structure are avoided, and the safety of the structure is ensured.
本申请涉及一种压重拉索构造，所述压重拉索构造包括：拉索，其两端分别锚固于主梁与桥墩上；以及拉索保护装置，所述拉索保护装置包括预埋管、设于所述预埋管内壁的拉索限位构件，所述拉索贯穿所述预埋管，所述拉索限位构件与所述拉索的接触面为弧面；所述拉索保护装置的预埋管设于所述主梁和/或所述桥墩中。本发明在主梁和/或桥墩中安装拉索保护装置，拉索保护装置中拉索限位构件与拉索的接触面为弧面，即使主梁发生纵向大位移变形，拉索在主梁的锚固位置或桥墩的锚固位置发生纵向变形时，拉索可以与对应的拉索限位构件发生接触，形成一段圆弧变形，大大减小了锚固端的弯折角，避免疲劳破坏而对结构安全及耐久性造成的不利影响，确保结构安全。
