    摘要:

    准格尔黄河特大桥主桥为 (160+440+160) m双塔双索面全漂浮体系混凝土梁斜拉桥,主梁宽为 28.4 m双边箱预应力混凝土结构,采用前支点挂篮悬臂浇筑施工,最大悬浇节段重 5 800 kN。为了保证挂篮整体刚度,挂篮承载平台采用钢箱梁结构,为方便挂篮运输及安装,长大构件采取分段制作高强螺栓连接;挂篮采用 “二次接长 ”技术减少高空支架搭设工程量;挂篮下放、行走、提升采用一键启动自动化同步控制技术,斜拉索索力转换装置、挂篮安装支架设计了一系列新工艺和创新技术。

    Abstract:

    The main bridge of Zhungeer Yellow River Super Major Bridge is a (160+440+160) m double tower double cable plane full floating system concrete grider cable-stayed bridge.The main beam is a 28.4m wide double box prestressed concrete structure.It was constructed by cantilever pouring with a front fulcrum hanging basket.The maximum weight of the cantilever pouring section is 5 800 kN.To ensure the integral rigidity of the hanging basket,the hanging basket bearing platform adopted the steel box girder structure.The long and large components were connected by high-strength bolts made in sections to facilitate the transportation and installation of the hanging basket.The hanging basket adopted the “secondary lengthening ” technology to reduce the quantities of high-altitude support erection;The one-click start automatic synchronous control technology was adopted for the lowering,walking,and lifting of the hanging basket.A series of new processes and innovative technologies are designed for the cable-stayed cable force conversion device and the hanging basket installation support.
