Prefabricated assembled box type pier and construction method thereof
The invention belongs to the technical field of constructional engineering and relates to a prefabricated assembled box-type pier and a construction method thereof. The prefabricated assembled box-type pier comprises a prefabricated bearing platform, a lower prefabricated section and an upper prefabricated section, wherein the lower prefabricated section and the upper prefabricated section are arranged on the top surface of the prefabricated bearing platform and spliced in a vertical direction. According to the prefabricated assembled box-type pier provided by the invention, a pre-buried lowersection hollow steel pipe and the hollow steel pipe of the bearing platform can play a role in restraining the lower prefabricated section, so that the lower prefabricated section can be prevented from inclining laterally, and construction safety degree is high; a pre-buried lower section hollow steel pipe and the hollow steel pipe of the bearing platform penetrate through splicing seams, and theupper section and the lower section form a whole through post-poured concrete, so that the integrity and shearing resistance of the spliced pier are improved; prestressed reinforcements are arrangedaround the structure of the pier and penetrate through the structure of the whole prefabricated assembled box-type pier, so that overall crack resistance and self-resetting capacity are improved. Thestructure of the prefabricated assembled box-type pier provided by the invention has good corrosion resistance, impermeability and shock resistance.
本发明涉及建筑工程技术领域，具体涉及一种预制拼装箱型桥墩及其施工方法，包括预制承台以及设置于预制承台顶面上下拼接的下预制节段和上预制节段；本发明提供的预制拼装箱型桥墩，预埋的下节段空心钢管和承台空心钢管能起到约束下预制节段的作用，可防止下预制节段侧倾，施工安全度高；预埋的下节段空心钢管和承台空心钢管穿过拼接缝，且后浇的混凝土将上、下节段形成整体，提高了拼装桥墩的整体性和抗剪能力；本结构四周均布置有预应力钢筋，预应力钢筋贯穿整个预制拼装箱型桥墩的结构，提高了整体的抗裂能力和自复位能力；本发明结构具有良好的耐腐蚀、抗渗性和抗震能力。
