Suspension bridge main cable erection construction method
The invention relates to the field of suspension bridge construction, and discloses a suspension bridge main cable erection construction method which comprises the following steps: S1, pile foundation anchorage construction is carried out; s2, main cable erection construction is conducted, and a main cable anchoring system is installed; s3, after the main cable strand is scattered, the main cable strand is connected with an anchor rod outside the front anchor face of the anchor body through an anchoring connector; s4, main cable arrangement is carried out; s5, mounting a cable clamp and fastening a cable clamp bolt; s6, catwalk hanging and sling installation are conducted; s7, cable hanging bracket construction and cable saddle arrangement are conducted; s8, cable crane installation and trial hoisting are carried out; and S9, steel box girder manufacturing and hoisting construction are conducted. The pile foundation is matched with the novel anchorage foundation of the open caisson, and the problem that the open caisson cannot sink due to poor geology and quicksand entering the open caisson is solved. A pile foundation bearing platform is poured in the open caisson, and a pile foundation and the open caisson are connected into a whole to serve as an anchorage foundation system of the main cable; the catwalk bearing cable is symmetrically dragged, and after the bearing cable is dragged, the line shape of the bearing cable is convenient to adjust.
本发明涉及悬索桥施工领域，公开了一种悬索桥主缆架设施工方法，包括如下步骤：S1，进行桩基锚碇施工；S2，进行主缆架设施工，进行主缆锚固体系的安装；S3，主缆索股散开后，通过锚固连接器与锚体前锚面外的锚杆相连；S4，进行主缆布置；S5，进行索夹安装及索夹螺栓紧固；S6，进行猫道改挂、吊索安装；S7，进行缆索吊架施工，缆索索鞍设置；S8，进行缆索吊安装及试吊；S9，进行钢箱梁制作及吊装施工。本发明采用桩基配合沉井的新型锚碇基础，解决因地质差，流砂进入沉井导致沉井无法下沉的问题。沉井内浇筑桩基承台，将桩基与沉井连为一体作为主索的锚碇基础体系；采用对称牵引猫道承重索，完成承重索牵引后，便于承重索线形的调整。
