Continuous rigid frame bridge side span cast-in-place section and closure section suspension type 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 suspension type construction method. Themethod which comprises the following steps that step 1, a suspension system of a side span cast-in-place section is designed, calculated and analyzed; step 2, a component is machined; step 3, transition pier construction is completed, and a hanging basket section is constructed to be close to a side span closure section; step 4, system conversion of the side span hanging basket and the suspensionsystem is conducted; step 5, the suspension system is anchored, and balancing of the weight of a rear anchoring beam is performed; step 6, the bottom of the hanging basket is pre-pressed, steel barsare bound, concrete is poured, and prestress tensioning and mud jacking are conducted; step 7, monitoring measurement, elevation adjustment and locking are carried out; and step 8, tensioning and mudjacking are conducted, pouring of the side span closure section is completed, and the suspension system is dismounted. By the adoption of the construction method, problems that in the prior art, in the construction process of 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悬吊式施工方法，包括如下步骤：步骤一，对边跨现浇段进行悬吊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，进行边跨挂篮与悬吊系统的体系转换；步骤五，对悬吊系统进行锚固，并对后锚固梁进行配重；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，标高调整和锁定；步骤八，张拉和压浆，完成边跨合拢段浇筑，拆除悬吊系统。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。
