Mortise and tenon type screwing installation prefabricated segment assembly pier connecting device

The invention discloses a tenon-and-mortise type screwing installation prefabricated segment splicing pier connecting device. The connecting device comprises a lower prefabricated segment, a connecting part A segment, a connecting part B segment and an upper prefabricated segment from bottom to top. During prefabrication, the lower prefabricated section is connected with the connecting part A section, and the upper prefabricated section is connected with the connecting part B section; during construction, the connecting part section B is hoisted and rotated, so that the connecting part section A and the connecting part section B form a mortise and tenon joint structure system. Factory prefabrication is easy, construction is convenient, the bridge pier building period can be remarkably shortened, and a rapid and effective solution is provided for rapid bridge building. 本发明公开了一种榫卯式旋拧安装预制节段拼接桥墩连接装置，所述连接装置自下而上包括：下预制节段、连接部分A段、连接部分B段、上预制节段。预制时，下预制节段与连接部分A段连接在一起、上预制节段与连接部分B段连接在一起；施工时，通过吊装旋转连接部分B段，使连接部分A段与连接部分B段组成一种榫
