Underwater pier bearing platform construction method
The invention relates to the technical field of building construction, in particular to an underwater pier bearing platform construction method. The method comprises the following steps: ground tie beam construction; pier column construction including, during pier column construction, pre-burying two pipes on a pier column, keeping the pre-buried pipes horizontal, sealing transparent adhesive tapes at two ends, completing pier column construction, installing a middle tie beam supporting system, removing the formwork of the pier column and installing round steel bars in the pipes after reaching70% of the design strength, hoisting first I-shaped steel pieces in the transverse direction of the bridge, wherein the center lines of the first I-shaped steel pieces are consistent with the longitudinal center lines of the two pier columns, the first I-shaped steel pieces are arranged at the upper ends of the pier columns and fixed to the round steel bars, and the two first I-shaped steel pieces are fixedly connected through two pull rods; and finally, middle tie beam construction, so that the support stability in the pier bearing platform construction process is greatly improved, steel barbinding in the pier bearing platform pouring process is more accurate, and the strength distribution of the poured pier bearing platform is more uniform.
本发明涉及建筑施工技术领域，尤其是一种水中桥墩承台施工方法，包括如下步骤：地系梁施工；墩柱施工，在墩柱施工时，在墩柱上预埋2根管，预埋管保持水平，两端透明胶封死，墩柱施工完毕，安装中系梁支撑体系，墩柱拆模并达到设计强度的70％后，在管中安装圆钢棒，吊装横桥向的第一工字钢，第一工字钢中心线与两墩柱纵向中心线保证一致，将第一工字钢设置在墩柱上端，第一工字钢固定在圆钢棒上，两根第一工字钢之间通过两道拉杆固定连接；最后进行中系梁施工，使桥墩承台施工过程中支架稳定性大大提高，桥墩承台浇筑过程中钢筋绑扎更准确，浇筑完成的桥墩承台强度分布更均匀。
