Prefabricated post-consolidation pier beam construction method and pier beam structure
The invention relates to a prefabricated post-consolidation pier beam construction method and a pier beam structure, and relates to the technical field of bridge construction. The pier beam construction method comprises the steps that firstly, a prefabricated pier is arranged on a pile foundation bearing platform, two prefabricated beams are symmetrically arranged at the top of the prefabricated pier, the positions of the two prefabricated beams are adjusted so that the two prefabricated beams can be at least partially placed at the top of the prefabricated pier, and a reserved gap not smaller than the preset length is reserved between the two prefabricated beams; and then the prefabricated beams placed above the top of the prefabricated pier are connected with the prefabricated pier, the first reserved steel bars at the adjacent ends of the two prefabricated beams are connected in the reserved gap, the second reserved steel bars at the top of the prefabricated pier are connected in the reserved gap, and finally the reserved gap is poured to form a post-pouring section. According to the pier beam construction method, an integral structure stable in structure can be formed, the requirement for the foundation construction scale is lowered on the premise that the foundation rigidity and the displacement limit value are met, and the investment of the foundation scale is reduced.
本申请涉及一种预制后固结的墩梁施工方法及墩梁结构，涉及桥梁施工技术领域。本墩梁施工方法首先在桩基承台上设置预制桥墩，并在预制桥墩的顶部对称设置两个预制梁，调节两个预制梁的位置，以使两个预制梁均至少部分搁置于预制桥墩的顶部，并使两个预制梁之间预留不小于预设长度的预留间隙，然后分别将搁置于预制桥墩顶部上方的预制梁与预制桥墩相连，在预留间隙内将两个预制梁相邻端的第一预留钢筋相连，在预留间隙内将预制桥墩顶部的第二预留钢筋相连，最后对预留间隙进行浇筑形成后浇段。本申请提供的墩梁施工方法可以形成结构稳定的整体结构，实现了在满足基础刚度和位移限值的前提下，还降低了基础建设规模的要求，减少了基础规模的投资。
