Sliding construction method for ultra-wide separated steel box girder of extra-large cable-stayed bridge
The invention discloses a sliding construction method for an ultra-wide separated steel box girder of an extra-large cable-stayed bridge, which is characterized in that the ultra-wide separated steel box girder is hoisted to a shelving pier of a river side supporting structure through a floating crane, and after an upstream beam body and a downstream beam body slide through a main tower through a sliding device, a cross beam is hoisted through the floating crane; the cross beam is connected with the upstream and downstream beam bodies through matching pieces and stacking plates, the left and right box bodies and the cross beam synchronously slide to the design position, the line shape is adjusted to meet the monitoring and design requirements, and sliding construction comprises a supporting structure, a steel longitudinal beam, a sliding device, a shelving pier and a tensioning structure; the steel longitudinal beam and the shelving pier are arranged on the supporting structure and are rigidly connected with the supporting structure; the sliding device is composed of a steel rail, a sliding shoe, a jacking oil cylinder, a lateral oil cylinder, a distribution beam, a pushing oil cylinder and a rail clamping device. Compared with the prior art, the device has the advantages of being simple in structure, capable of achieving efficient, accurate, safe and synchronous sliding erection of the ultra-wide separation type steel box girder, high in working efficiency, low in labor intensity and safe in construction.
本发明公开了一种特大斜拉桥超宽分离式钢箱梁的滑移施工方法，其特点是采用超宽分离式钢箱梁通过浮吊吊装至江侧支撑结构的搁置墩上，通过滑移装置将上下游梁体滑移过主塔后利用浮吊吊装横梁，横梁与上下游梁体通过匹配件、码板连接，左右箱体及横梁同步滑移至设计位置，调整线形符合监控及设计要求，该滑移施工的实现包括：支撑结构、钢纵梁、滑移装置、搁置墩、张拉结构；所述钢纵梁、搁置墩置于支撑结构上并与其刚性连接；所述滑移装置由钢轨、滑靴、顶升油缸、侧向油缸、分配梁、顶推油缸、夹轨器组成。本发明与现有技术相比具有结构简单，可实现超宽分离式钢箱梁高效、精确、安全、同步滑移架设，工作效率高，劳动强度低、施工安全。
