Ultra-high performance concrete combined pier and construction process thereof
The invention relates to an ultra-high performance concrete combined pier and a construction technology thereof, and belongs to the technical field of bridge engineering prefabricated pier manufacturing. The combined bridge pier comprises a UHPC bridge pier body which is formed by pouring a reinforcing mesh cage and a UHPC material, a light permanent inner mold is arranged in the UHPC bridge pier body, and the light permanent inner mold is not dismantled after construction and is installed in a bridge pier permanent structure together with the UHPC bridge pier body; the structure of the pier is the same as that of a solid pier, the problem that an inner mold of a hollow pier produced through a traditional pouring method is difficult to machine, install and dismantle is solved, the construction technology of the whole pier is simple, and the site construction period is short; the light permanent inner mold is made of a light cement-based foaming material, the volume weight is only 1/5 of that of concrete, so that the dead weight of the pier is low, a stiffening rib structure can be independently manufactured in the structure, the local stability of a thin-wall plate is regulated and controlled, and the designability of the pier structure is improved.
本发明涉及一种超高性能混凝土组合式桥墩及其施工工艺，属于桥梁工程预制桥墩制造技术领域。组合式桥墩包括UHPC桥墩本体，其由钢筋网笼和UHPC材料浇筑而成，UHPC桥墩本体的内部设置有轻质永久内模，其在施工后不拆除，与UHPC桥墩本体一起安装至桥墩永久结构中；该桥墩的结构与实心桥墩无异，但解决传统浇筑法生产空心桥墩内模加工、安装和拆除困难的问题，整个桥墩的施工工艺简单，现场施工工期短；轻质永久内模采用轻质水泥基发泡材料制成，容重仅仅为混凝土1/5，使得桥墩自重低，该结构中可单独制作加劲肋的结构，调控薄壁板件的局部稳定性问题，提高桥墩结构的可设计性。
