Cable sleeve structure of steel box girder cable-stayed bridge and post-installation construction method
The invention provides a cable sleeve structure of a cable-stayed bridge of a steel box girder and a post-installation construction method, a structural diaphragm plate is arranged in the steel box girder, and an anchor box structure is fixedly installed on the structural diaphragm plate; the anchor box structure comprises side plates which are symmetrically arranged, and sealing plates are symmetrically and vertically fixed to the top ends and the bottom ends of the side plates to form the anchor box structure with the four faces closed. A seat plate and an anchor backing plate are fixed at the bottom end of the anchor box structure; a cable sleeve is installed in the anchor box structure, the top end of the cable sleeve penetrates through a bridge deck of the steel box girder, and a hole sealing plate is fixed to the junction of the cable sleeve and the bridge deck. According to the structure and the post-installation construction method, the method that the cable sleeve is movably arranged firstly, then the cable sleeve and the stay cable are positioned and adjusted again on the construction site, and then fixing is conducted is adopted, so that the influence of accumulated errors of elevation deviation and mileage deviation of installation of all the steel box girder sections during hoisting construction of the steel box girder sections is effectively overcome; and the actual coordinate of the cable sleeve meets the construction requirement.
本发明提供了一种钢箱梁斜拉桥索套管结构及后安装施工方法，钢箱梁的内部设置有构造横隔板，构造横隔板上固定安装有锚箱结构；所述锚箱结构包括对称布置的侧板，侧板的顶端和底端对称垂直固定有封板并形成四面封闭的锚箱结构；所述锚箱结构的底端固定有座板和锚垫板；所述锚箱结构的内部安装索套管，索套管的顶端贯穿钢箱梁的桥面板，在索套管和桥面板的交界部位固定有封孔板。此结构及后安装施工方法，采用后先活动布置索套管，再采用施工现场进行索套管与斜拉索重新定位调整，并后固定的方法，有效克服可钢箱梁节段吊装施工各钢箱梁节段安装高程偏差与里程偏差的累计误差影响，确保索套管实际坐标满足施工要求。
