description The utility model provides a composite pier based on prefabrication and cast-in-place, which belongs to the technical field of bridge structures and comprises a bearing platform, a concrete filled steel tube composite bottom section, a prefabricated hollow interlayer composite middle section, a prefabricated hollow interlayer composite top section, a connecting hole group, external reinforced concrete and a cover beam. A first connecting groove is formed in the top surface of the bearing platform; the laminated bottom section comprises a concrete filled steel tube and a first flange ring, a certain height is reserved at the top of the concrete filled steel tube, the bottom of the concrete filled steel tube is embedded into the first connecting groove and filled with UHPC, and the first flange ring is welded to the top of the concrete filled steel tube; wet joint is carried out on the connecting positions of all the components through UHPC, the effect equivalent to cast-in-place is achieved, and therefore the
