Prefabricated assembled hollow pier with transverse partition plates and construction method
The invention provides a prefabricated assembled hollow pier with transverse partition plates and a construction method, and relates to the technical field of bridge construction. The hollow pier sequentially comprises a foundation, a general section and a top cap section from bottom to top, and foundation connecting steel bars and foundation connecting columns are arranged at the top of the foundation; general section transverse partition plates are arranged at the top and the bottom of the general section, a general section reserved groove is arranged in the general section transverse partition plate located at the bottom, and a general section connecting steel bar is arranged on the general section transverse partition plate located at the top; a top cap section transverse partition plate is arranged at the bottom of the top cap section, and a top cap section reserved groove is formed in the top cap section transverse partition plate at the bottom; during splicing, the connecting steel bars and the connecting columns located on a lower portion extend into the corresponding reserved grooves located on the upper portion, and a high-strength slurry is poured into the reserved grooves; and prestressed pipelines are pre-buried in the foundation, the general section and the top cap section, and connection is performed by penetrating through full-length prestressed tendons. By theadoption of the scheme, a prestress on a pier wall can be flexibly arranged, and manufacturing is easy and convenient.
本发明提供适用于带横隔板的预制拼装空心桥墩及施工方法，涉及桥梁建造技术领域。由下及上依次包括基础、一般节段和顶帽节段，基础的顶部设置基础连接钢筋和基础连接柱；一般节段的顶部和底部设置一般节段横隔板，位于底部的一般节段横隔板上设置一般节段预留槽，位于顶部的一般节段横隔板上设置一般节段连接钢筋；顶帽节段的底部设置顶帽节段横隔板，位于底部的顶帽节段横隔板上设置顶帽节段预留槽；拼装时将位于下方的连接钢筋和连接柱伸入位于上方的对应的各预留槽中，并在各预留槽中灌注高强浆料；基础、一般节段、顶帽节段均预埋预应力管道，通过穿入通长预应力束进行连接；采用本方案，能够使墩壁上预应力布置灵活、制造简便。
