Concrete-filled steel tube prefabricated pier
The invention provides a concrete-filled steel tube prefabricated pier, and belongs to the technical field of bridge construction. The prefabricated pier is used for solving the technical problems that an existing prefabricated pier is not high in strength and connecting strength, inconvenient to install and poor in shock absorption performance and centering performance. The prefabricated pier comprises a pier base, a connecting assembly, an assembling assembly and a centering rod, the pier base comprises a damping base, a guide steel pipe and a base steel pipe, the connecting assembly comprises a connecting steel pipe and a connecting cement base, and a damping buffer assembly is arranged between the damping base and the connecting steel pipe; and the assembling assembly comprises a steel pipe fitting, a cement shell, an outer reinforcement cage, an inner cement column, an inner reinforcement cage and reinforcement bundles. The structural strength of the pier body is improved through the outer reinforcement cage, the inner reinforcement cage and the reinforcement bundles, bosses, steel cylinders and positioning pins bear transverse shearing force, the connecting strength can be improved, the damping buffer assembly can achieve damping and energy absorption, the steel cables are anchored to the ground, the stability of the pier can be enhanced, the centering rods are inserted into the centering holes, and centering performance is good.
本发明提供了一种钢管混凝土预制桥墩，属于桥梁建筑技术领域，用于解决现有预制桥墩自身强度和连接强度不高，安装不便，减震性能和对中性差的技术问题。本发明包括桥墩底座、连接组件、拼装组件和对中杆，桥墩底座包括减震底座、导向钢管和底座钢管，连接组件包括连接钢管和连接水泥座，减震底座和连接钢管之间设置有减震缓冲组件，拼装组件包括钢管件、水泥外壳、外钢筋笼、内水泥柱、内钢筋笼和钢筋束；本发明通过外钢筋笼、内钢筋笼和钢筋束提高桥墩本体的结构强度，凸台、钢筒和定位销承受横向剪力，能提高连接强度，减震缓冲组件能减震吸能，钢缆锚接在地面上，能增强桥墩稳定性，通过对中杆插合在对中孔内，对中性好。
