Description

Technical Field

[0001] The invention relates to an improvement of a suspension bridge installation technology, belongs to the field of bridges, and in particular to a double-sliding auxiliary main cable saddle applied in a mountain environment. Background Art

[0002] A suspension bridge, also known as a suspension bridge, refers to a bridge with cables (or steel chains) suspended through cable towers and anchored on both banks (or both ends of the bridge) as the main load-bearing components of the upper structure. The geometric shape of the cables is determined by the balance of forces and is generally close to a parabola. Many hangers are suspended from the cables to suspend the bridge deck. Stiffening beams are often set between the bridge deck and the hangers to form a combined system with the cables to reduce the deflection deformation caused by the load. Due to the geographical location restrictions of the bridge construction, some suspension bridges can only be installed with rotary anchors. However, the cable saddles installed on the existing rotary anchors are fixed. In the mountain environment, due to the different geological conditions of the mountains, it is necessary to process the mountains according to the situation to build corresponding rotary anchors. When constructing rotary anchors on the mountains, the main cables will be affected by temperature, wind loads, and vehicle vibrations, which will be amplified, causing the cable saddles to be subjected to excessive stress in local areas, which may threaten the stability of the bridge structure and may cause bridge safety accidents.

[0003] A Chinese patent application with application number CN202410131925.3 and application date January 31, 2024 discloses a saddle system for a revolving main cable suspension bridge and a method for installing a revolving main cable, including a revolving bank anchor, wherein a revolving cable saddle is provided on the central axis and on both sides of the revolving bank anchor, the revolving cable saddle includes a saddle body, a saddle head is provided on the saddle body, a saddle groove is provided on the saddle head, and the saddle groove of the revolving cable saddle opens upward. By changing the entry direction of the revolving cable saddle, the entry directions of the revolving cable saddle and the conventional cable saddle are both from top to bottom, and the arrangement of the revolving main cable in each saddle is the same, thereby reducing the workload in design and construction. The above scheme reduces the workload in construction by changing the entry direction of the revolving cable saddle, but does not solve the problem of local instability of force on the main cable in the saddle part, thereby causing safety accidents of the bridge.
