Cluster grouting sleeve assembling pier connected with prefabricated bearing platform and construction method
The invention provides a cluster grouting sleeve assembled pier connected with a prefabricated bearing platform and a construction method. The pier comprises a foundation, a pier column section and atop cap section. The foundation is formed by connecting foundation prefabricated sections through foundation connecting seams, connecting steel bars are pre-buried in the top surfaces of the foundation prefabricated sections and the prefabricated pier column sections, bundling connecting sleeves are pre-buried in the bottom surfaces of the corresponding prefabricated pier column sections and the prefabricated top cap sections, the pre-buried connecting steel bars penetrate into the bundling connecting sleeves, and then high-strength grouting materials are poured into the bundling connecting sleeves. The top cap connecting sections and the top cap section are connected through top cap splicing seams, and then the connecting bolts are connected with the connecting sleeves; steel strands penetrate through pre-buried corrugated pipes pre-buried in the top cap sections, pier column sections and foundation prefabricated sections to be pre-embedded with corrugated pipes., the corrugated pipesare embedded in the top cap sections, the pier column sections and the foundation prefabricated sections, the steel strands are tensioned at the top of the top cap and in the foundation, then foundation connecting joints are constructed, and then concrete is poured to complete splicing. The spliced pier connecting steel bars are arranged in a bundled mode, the construction tolerance is large, theconstruction precision requirement is low, the splicing difficulty is small, the grouting efficiency is high, the top cap sections are quickly spliced, and prestress installation is convenient and fast.
本发明提供一种与预制承台相连的集束灌浆套筒拼装墩及施工方法，桥墩包括基础、墩柱节段和顶帽节段，基础由基础预制节段通过基础连接缝连接，基础预制节段、预制墩柱节段顶面预埋连接钢筋，相应预制墩柱节段、预制顶帽节段底面预埋集束连接套筒，通过将预埋连接钢筋穿入集束连接套筒，再灌注高强灌浆料；将顶帽连接段与顶帽节段通过顶帽拼接缝连接，再将连接螺栓与连接套筒相连；将钢绞线穿过预埋在顶帽节段、墩柱节段、基础预制节段上预埋波纹管，在顶帽顶部和基础内张拉钢绞线，再施工基础连接缝、后灌混凝土完成拼装。该拼装桥墩连接钢筋集束布置，施工容差大、施工精度要求低，拼装难度小，灌浆效率高，顶帽节段间拼装快速，预应力安装便捷。
