Novel hybrid connection prefabricated assembled bridge pier and assembling method
The invention belongs to the technical field of bridge engineering, and provides a novel hybrid connection prefabricated assembled pier and an assembling method.The novel hybrid connection prefabricated assembled pier is characterized in that a bearing platform, a first pier body prefabricated section and a second pier body prefabricated section are connected and fixed through a first connecting device and a second connecting device, and then are connected and fixed by applying prestress; the anti-shearing capacity of the joint of the bearing platform, the first pier body prefabricated section and the second pier body prefabricated section is improved through application of prestress and cooperation of the anti-shearing device and the connecting glue, manual scabbling is replaced by the anti-shearing device, manpower is saved, the pier is not damaged, all-directional shearing resistance is achieved, the installation efficiency is improved, and the pier is not damaged due to the fact that scabbling treatment is not conducted; the safety of the prefabricated bridge pier is improved, the service life of the prefabricated bridge pier is prolonged, meanwhile, cast-in-place concrete is not needed, the construction speed is greatly increased, and the friction force at the splicing seam of the bridge pier and the self-resetting capacity of the bridge pier are improved due to application of prestress.
本发明属于桥梁工程技术领域，提供一种新型混合连接预制拼装桥墩及拼装方法，本发明的承台、第一墩身预制段、第二墩身预制段先通过第一连接装置和第二连接装置进行连接固定，然后通过施加预应力连接固定；预应力的施加以及抗剪力装置与连接胶相配合提高了承台、第一墩身预制段、第二墩身预制段连接处的抗剪能力，抗剪切装置取代人工凿毛，节省人力，不损伤桥墩，全方位抗剪，提高安装效率，由于不进行凿毛处理，所以不损伤桥墩，提高了预制桥墩的安全性以及使用寿命，同时不需要现浇混凝土，大大加快了施工速度，而预应力的施加也分提高了桥墩的拼接缝处的摩擦力和桥墩的自复位能力。
