Continuous rigid frame bridge side span cast-in-place section and closure section self-anchored construction method
The invention relates to the field of bridge construction, in particular to a continuous rigid frame bridge side span cast-in-place section and closure section self-anchored construction method. The method comprises the following steps: step 1, designing, calculating and analyzing of a self-anchored system a side span cast-in-place section; step 2, processing components; step 3, completing construction from an approach bridge to a transition pier, and the hanging basket sections are constructed to be close to the side span closure section sections; step 4, carrying out system conversion between a side span hanging basket and the self-anchoring system through the self-anchoring system; step 5, fixing the self-anchoring system; step 6, pre-pressing the bottom of the hanging basket, binding steel bars, pouring concrete, and carrying out prestress tensioning and mud jacking; step 7, carrying out monitoring measurement, adjustment and locking; and step 8, carrying out tensioning and mud jacking, completing pouring of a side span closure section, and dismounting the anchoring system. With the adoption of the construction method, problems that in the prior art, in the construction processof a bridge side span cast-in-place section and a closure section, the workload is large, the pier body performance is poor, and the construction cost is high are solved.
本发明涉及桥梁施工领域，尤其涉及一种连续刚构桥边跨现浇段及合拢段自锚式施工方法，包括如下步骤：步骤一，对边跨现浇段进行自锚固系统进行设计和计算分析；步骤二，对构件进行加工；步骤三，完成引桥至过渡墩的施工，并将挂篮节段施工至靠近边跨合拢段节段；步骤四，利用自锚固系统进行边跨挂篮与自锚固系统的体系转换；步骤五，固定自锚固系统；步骤六，预压挂篮篮底、钢筋绑扎、浇筑混凝土、预应力张拉及压浆；步骤七，进行监控测量、调整和锁定；步骤八，张拉和压浆，完成边跨合拢段浇筑，拆除锚固系统。通过采用本方案的施工方法，解决了现有技术中桥梁边跨现浇段及合拢段的施工过程中工作量大、墩身性能差、施工成本高的问题。
