锦州市云飞南街小凌河大桥主桥为双套拱斜拉桥,索塔由两个倾斜的钢拱塔组成。主要介绍了拱塔竖转方案的设计与施工,拱塔施工采用竖向转体方法,即钢拱塔节段在钢箱梁桥面上安装完成后,在内拱塔上安装起扳三角架,利用计算机控制液压同步提升系统首先完成内拱塔的竖转施工,然后以内拱塔为提升支架,进行外拱塔的竖转施工,巧妙地解决了外拱塔竖转的难题,设计大胆新颖,技术含量高,为类似工程提供了一定的借鉴。
Jinzhou Yunfei South Street Xiaolinghe Bridge main bridge is a double arch cable-stayed bridge, the tower consists of two inclined steel arch tower. Mainly introduces the design and construction of the vertical arch of the arch, the use of vertical turret arch construction method, that is, after the installation of steel arch section in the steel box girder bridge deck, , The use of computer-controlled hydraulic synchronous hoisting system to complete the first vertical turret construction, and then to the inner arches to enhance the stent, the outer arches of the vertical rotation construction, cleverly solved the problem of the outer arches vertical rotation, the design bold new , High technical content, provided a certain reference for similar projects.
