Cluster grouting corrugated pipe assembled pier connected with prefabricated bearing platform and construction method
The invention provides a cluster grouting corrugated pipe assembled pier connected with a prefabricated bearing platform and a construction method. The assembled pier comprises a foundation, pier column sections and top cap sections. The foundation is formed by connecting foundation prefabricated sections through foundation connecting seams, connecting steel bars are pre-buried in the top surfacesof the foundation prefabricated sections and the prefabricated pier column sections, bundling connecting corrugated pipes are pre-buried in the bottom surfaces of the corresponding prefabricated piercolumn sections and the prefabricated top cap sections, the pre-buried connecting steel bars penetrate into the bundling connecting corrugated pipes, and then a high-strength grouting materials are poured; the top cap connecting sections and the top cap sections are connected through top cap splicing seams, and then the connecting steel plates are connected in a welded mode; and steel strands penetrate through the pre-buried corrugated pipes pre-buried in all the sections and are arranged in a U shape, the steel strands are tensioned at the top of the top cap, 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, a construction tolerance is large, a construction precisionrequirement is low, splicing difficulty is small, grouting efficiency is high, the top cap sections are quickly spliced, prestress installation is convenient and fast, and cost is low.
本发明提供一种与预制承台相连的集束灌浆波纹管拼装墩及施工方法，拼装桥墩包括基础、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波纹管，通过将预埋连接钢筋穿入集束连接波纹管中，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，再将连接钢板相互焊连；将钢绞线穿过预埋在各节段上预埋波纹管，并采用U型布置，在顶帽顶部张拉钢绞线，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，成本低。
