Continuous beam construction method shared by pier-side support pre-pressing and 0 # block external anchoring
The invention relates to a continuous beam construction method shared by pier-side support pre-pressing and 0 # block external anchoring, and belongs to the technical field of bridge construction, and the continuous beam construction method comprises the following steps: S1, constructing a bearing platform pier body, reserving an embedded part on a bearing platform, and anchoring a plurality of anchoring steel strands on two sides of the bearing platform; s2, a support used for supporting the No.0 block is built; s3, counter-force beams are arranged on the supports, the anchoring steel strands are tensioned, and the supports are pre-pressed; s4, a temporary support is arranged, and a metal corrugated pipe is pre-buried; s5, a zero block of equal-strength post-tensioning prestressed steel strand is poured, and then an external anchoring steel strand is tensioned and anchored; s6, carrying out subsequent hanging basket cantilever construction on a continuous beam; and S7, the anchoring steel strands are tensioned again according to the stress conditions of the continuous beams at the two ends of the bearing platform, the pre-pressing process of the support can be simplified through the steel strands anchored in vitro, the effect is improved, and the stress balance of the two ends of the bearing platform can be guaranteed through the steel strands anchored in vitro.
本发明涉及墩旁支架预压与0号块体外锚固共用的连续梁施工方法，属于桥梁施工技术领域，包括如下步骤：S1、施工承台墩身，并在承台上预留预埋件并将若干锚固钢绞线锚固在承台两侧；S2、搭建用于支撑0号块的支架；S3、在支架上设置反力梁并张拉锚固钢绞线，预压支架；S4、设置临时支座并预埋金属波纹管；S5、浇筑0号块等强后张拉预应力钢绞线而后张拉体外锚固钢绞线并锚固；S6、进行后续挂篮悬臂施工连续梁；S7、根据承台两端的连续梁受力情况再次张拉锚固钢绞线，通过体外锚固的钢绞线能够简化支架预压的流程、提高效果，并能够利用体外锚固的钢绞线保证承台两端的受力平衡。
