Construction method for capping beam of cross-sea bridge
The invention relates to the technical field of bridge engineering, and discloses a cross-sea bridge capping beam construction method which comprises the following steps: S1, early-stage measurement; s2, a U-shaped supporting block is welded; s3, corbels and jacks are installed; s4, main beams and secondary beams are erected; s5, a bottom die of the bent cap is installed; s6, pile head concrete is broken and removed; s7, measuring and adjusting a bottom die; s8, bent cap steel bars are bound; s9, a cover beam formwork is installed; step S10, pouring capping beam concrete; s11, the bent cap is demoulded, and concrete curing is carried out; and S12, the side formworks, the bottom formworks, the jacks, the main beams, the secondary beams and the brackets are dismantled. The problems that a common offshore cast-in-place bent cap hoop method support is low in bearing load, insufficient in safety, difficult to dismantle, low in mounting and dismounting efficiency, incapable of accurately adjusting the elevation of a bottom formwork and the like are solved, the construction safety of the offshore bent cap is ensured, the construction quality of the bent cap is effectively improved, and the construction cost is reduced.
本发明领域涉及桥梁工程技术领域，公开了一种跨海大桥盖梁施工方法，包括如下步骤：步骤S1，前期测量；步骤S2，焊接凹字形支承块；步骤S3，安装牛腿及千斤顶；步骤S4，搭设主梁及次梁；步骤S5，安装盖梁的底模；骤S6，桩头混凝土破除；步骤S7，底模测量、调整；步骤S8，盖梁钢筋绑扎；步骤S9，盖梁模板安装；步骤S10，浇筑盖梁混凝土；步骤S11，盖梁拆模，混凝土养护；步骤S12，拆除侧模、底模、千斤顶、主梁、次梁及牛腿。本发明不仅解决了一般海上现浇盖梁抱箍法支架的承受荷载低，安全性不足、支架拆除困难、安拆效率低、底部模板高程无法精确调节等问题，还确保了海上盖梁施工安全，有效提高了盖梁施工质量，降低了施工成本。
