Continuous beam asynchronous construction control method combining hanging basket prepressing and external supporting
The invention provides a hanging basket prepressing and external supporting combined continuous beam asynchronous construction control method which comprises the following steps: constructing a bearing platform pier body, and reserving related embedded parts and garland steel strands on the bearing platform pier body; erecting a bracket to construct a No.0 block; a hanging basket is installed, and pre-pressing is conducted by means of the pre-buried steel strand; a side span section 1 is poured, the hanging basket moves forwards, and an external support is constructed; mid-span anchoring steel strands are constructed, and then side-mid-span asynchronous suspension grouting construction is conducted till the side spans and the mid-span are closed; through the cooperation of the hanging basket pre-pressing steel strand, the side span side body external support and the section, ahead of the middle span, of the side span, the steel pipe support on one side is saved, meanwhile, the hanging basket pre-pressing problem is solved, the weight of the continuous beam is guided to be pressed towards the side span, clear side span steel pipe pile pressing and middle span steel strand pulling are formed, and the construction efficiency is improved. The problems of overturning caused by unbalanced bending moment in the construction process of the continuous beam and overturning of the beam body towards the side midspan are solved, and construction safety is guaranteed.
本发明提供了一种挂篮预压与体外支撑结合的连续梁异步施工控制方法，包括如下步骤：施工承台墩身，并在承台墩身上预留相关预埋件及拉花后的钢绞线；搭设支架施工0号块；安装挂篮，并借助预埋钢绞线预压；浇筑边跨1号节段、挂篮前移并施工体外支撑；施工中跨锚固钢绞线，后续进行边中跨异步悬灌施工直至边跨、中跨合龙；通过利用挂篮预压钢绞线、边跨侧体外支撑以及边跨较中跨先行一个节段的配合，在节省一侧钢管支撑的同时，也解决了挂篮预压问题，并引导连续梁重量往边跨压，形成明确的边跨钢管桩受压中跨钢绞线受拉，解决连续梁施工过程中不平衡弯矩导致的倾覆以及梁体往边中跨那侧倾覆问题，保证施工安全。
