Segmental beam sliding assembly construction method
The invention discloses a segmental beam sliding assembly construction method. The construction method comprises the following steps: mounting a sliding bracket, mounting a sliding rail, mounting a beam moving trolley, lifting a beam to the beam moving trolley, transporting the beam by the beam moving trolley, splicing segmental beams, temporarily tensioning, tensioning internal prestressed tendons, repeating the mounting of the next segmental beam, constructing a mid-span closure segment, and dismounting the sliding bracket. According to the invention, the segmental beams are assembled by adopting a sliding assembly method, the segmental beams do not influence the passage or other operations at the lower part of the bracket during sliding assembly, the operating environment with passage requirements or limited topographic conditions can be met, the requirement on segmental beam hoisting equipment is lower by adopting the sliding method, and the cost of the installation equipment is effectively reduced.
本发明公开了一种节段梁滑移拼装施工方法，包括如下步骤：安装滑移支架→安装滑移轨道→安装移梁小车→吊梁至移梁小车→移梁小车运梁→拼接节段梁→临时张拉→体内预应力束张拉→重复下一段节段梁的安装→中跨合龙段施工→拆除滑移支架。本发明采用滑移拼装的方法拼装节段梁，节段梁在滑移拼装时不影响支架下部通行或其他作业，能够满足有通行要求或地形条件限制的作业环境，采用滑移法对节段梁起吊设备要求较低，有效降低了安装设备的成本。
