Lifting closure construction method for arch ribs of arch bridge
The invention provides a lifting closure construction method of arch ribs of an arch bridge. An arch rib is divided into two arch foot-arch rib sections, an arch rib lifting section and two arch rib closure sections for connecting the arch rib lifting section and the arch foot-arch rib sections. The arch foot-arch rib sections are directly assembled at the designed installation position, the archrib lifting section is assembled on a support below the designed installation position, and the arch rib lifting section is lifted to the designed elevation after assembly and connected with the archfoot-arch rib sections through the closure sections. The arch foot side arch ribs and the arch rib lifting section can be spliced at the same time, and the construction period can be shortened; the arch rib lifting section is machined at a lower position and then lifted to the designed elevation after machining is completed, so that the aerial work amount is reduced, the deformation amount of thearch rib in the horizontal direction and the vertical direction in the lifting process is reduced, and the construction safety and the installation precision are improved.
本发明提供一种拱桥拱肋的提升合龙施工方法，将拱肋划分为两个拱脚拱肋段、一个拱肋提升段，以及两个连接拱肋提升段和拱脚拱肋段的拱肋合龙段；拱脚拱肋段直接在设计安装位置拼装，拱肋提升段在设计安装位置下方的支架上拼装，拼装完成后提升至设计标高，并通过合龙段与拱脚拱肋段。本发明的拱脚侧拱肋和拱肋提升段可同时拼装，可以缩短工期；拱肋提升段的在较低的上加工，加工完成后再提升至设计标高，一方面减少了高空作业量，另一方面减少提升过程中拱肋在水平方向和竖向方向变形量，提高了施工的安全性和安装精度。
