Fabricated bridge pile foundation mechanical connection structure and construction method
The invention relates to the technical field of assembly type bridge construction, in particular to an assembly type bridge pile foundation mechanical connecting structure which is characterized by comprising a lower assembly and an upper assembly, a lower first steel plate in the lower assembly is of a disc structure, and an embedded steel plate is mounted and connected to the lower end face of the lower first steel plate in an attached mode; the first steel plate and the pre-buried steel plate form a lower connecting piece, the anchor bar sleeve is pre-buried in the pre-buried steel plate, the lower end of the anchor bar sleeve is lifted out of the lower end face of the pre-buried steel plate, the lower connecting piece is provided with a through hole rotating in the axial direction, the main bar lower connector is arranged in the through hole, and the upper end of the pile foundation main bar is connected to the main bar lower connector. The lower component and the upper component are respectively provided with a main reinforcement lower connector and a main reinforcement upper connector, and the main reinforcement lower connector and the main reinforcement upper connector can be inserted, so that the lower component and the upper component are combined. Operation is easy and convenient, control is accurate, the connection strength of the precast piles can be greatly improved, and the anti-seismic performance is improved. The invention further provides a construction method of the fabricated bridge pile foundation mechanical connection structure.
本发明涉及装配式桥梁施工技术领域，装配式桥梁桩基机械连接结构，其特征在于：包括下部组件和上部组件，下部组件中下部第一钢板为圆盘结构，预埋钢板贴合的安装并连接在下部第一钢板的下端面，第一钢板和预埋钢板形成下部连接件，锚筋套筒预埋在所述预埋钢板中，且锚筋套筒的下端提出预埋钢板的下端面，下部连接件具有轴向管转的通孔，主筋下连接器置于通孔中，桩基主筋的上端连接在主筋下连接器，下部组件和上部组件分别具有主筋下连接器和主筋上连接器，主筋下连接器和主筋上连接器可插装，使下部组件和上部组件组合。操作简便，控制精确，可大大提高预制桩的连接强度，提高其抗震性能。本发明还提出装配式桥梁桩基机械连接结构的施工方法。
