Modularized prefabricated multi-cavity reinforced concrete pier and implementation method
The invention discloses a modular prefabricated multi-cavity reinforced concrete pier and an implementation method. The modular prefabricated multi-cavity reinforced concrete pier comprises transverse segments, cast-in-place bearing platforms and cap beams. A plurality of transverse sections are arranged on the cast-in-place bearing platform, the cap beam is arranged on the transverse section at the uppermost end, assembly type transverse partition plates are arranged between the transverse sections, and the assembly type transverse partition plates and the transverse sections are connected through vertical anchoring connectors; the whole of the transverse sections and the fabricated diaphragm plates is downwards anchored on the cast-in-place bearing platform through prestressed tendons and upwards anchored on the cap beam; the transverse section is formed by transversely splicing various prefabricated section modules, each prefabricated section module comprises an inner-layer steel pipe, an outer-layer steel pipe and a concrete layer filled between the inner-layer steel pipe and the outer-layer steel pipe, and the prefabricated section modules are anchored through finish rolling deformed steel bars; the fabricated diaphragm plate comprises a peripheral steel plate and an ultra-high performance concrete layer filled in the peripheral steel plate. Reliable connectivity of the prefabricated segment type pier can be guaranteed, and the problems of transportation and assembly of prefabricated parts under the complex mountain area environment are solved.
本发明公开一种模块化预制多腔室钢筋混凝土桥墩及实施方法，包括横向节段、现浇承台和帽梁；现浇承台上设置多个横向节段，帽梁设置于最上端的横向节段上，各横向节段之间均设有装配式横隔板，装配式横隔板与横向节段之间通过竖向锚固连接器连接；横向节段和装配式横隔板的整体通过预应力筋向下锚固在现浇承台上，向上锚固在帽梁上；横向节段由多种预制节段模块横向拼接而成，预制节段模块包括内层钢管、外层钢管及填充于两者间的混凝土层，各预制节段模块之间通过精轧螺纹钢锚固；装配式横隔板包括外围钢板以及填充于外围钢板内的超高性能混凝土层。本发明能够保证预制节段式桥墩的可靠连接性，解决山区复杂环境下的预制构件的运输和拼装难题。
