Prefabricated UHPC formwork core-filled concrete bridge pier containing framework and construction method thereof
A prefabricated UHPC formwork core-filled concrete bridge pier containing a framework comprises a bridge pier bearing platform, the bridge pier bearing platform is provided with a prefabricated and formed UHPC formwork, a pouring cavity used for pouring concrete is formed in the UHPC formwork, and the framework which is embedded in the UHPC formwork and used for improving the strength of the UHPC formwork is arranged in the pouring cavity. A construction method of the prefabricated UHPC formwork core-filled concrete bridge pier containing the framework specifically comprises the following steps that S1 according to actual bridge attributes, the prefabricated UHPC formwork and the framework are connected into a whole; S2 the UHPC formwork is transported to the bridge pier bearing platform, and the UHPC formwork is fixed; and S3 concrete is poured into the pouring cavity. The framework is pre-buried in the UHPC formwork, the UHPC formwork can be supported, the strength of the UHPC formwork is further improved, concrete in the pouring cavity and the UHPC formwork can be connected into a whole, through the prefabricated UHPC formwork, operation equipment can conveniently transport the UHPC formwork to the bridge pier bearing platform, transportation is convenient, concrete can be directly poured into the pouring cavity, and the construction efficiency is improved.
一种含骨架的预制UHPC模壳填芯混凝土桥墩，包括桥墩承台，所述桥墩承台上装设有预制成型的UHPC模壳，所述UHPC模壳内成型有用于浇筑混凝土的浇筑腔，所述浇筑腔内布置有预埋在UHPC模壳内用以提高UHPC模壳强度的骨架；一种含骨架的预制UHPC模壳填芯混凝土桥墩的施工方法，具体包括以下步骤：S1：根据实际桥梁属性预制UHPC模壳与骨架并连成整体；S2：将UHPC模壳运输至桥墩承台处将UHPC模壳固定；S3：向浇筑腔内浇筑混凝土；在UHPC模壳内预埋骨架，能够对UHPC模壳进行支撑，进一步提高UHPC模壳的强度，并且能够将浇筑腔内的混凝土与UHPC模壳连成整体，通过预制的UHPC模壳，便于作业装备将UHPC模壳运输至桥墩承台上，运输方便，并且能够直接向浇筑腔内浇筑混凝土，提高了施工效率。
