Novel combined prefabricated assembled pier
The invention discloses a novel combined prefabricated assembled pier, and belongs to the technical field of civil construction and transportation industry bridge engineering. Comprising a prefabricated bottom bearing platform, a prefabricated pier body, a prefabricated cover beam, a grouting sleeve for connecting the bearing platform and the pier body, and a combined structure system of a tenon core socket. A U-shaped steel bar is reserved on the top face of the pier connected with the bent cap, a UHPC cylindrical socket column matched with a pier column grouting sleeve is reserved on the bearing platform, and a groove matched with a bearing platform tenon core is reserved at the bottom of the pier body. A groove is reserved in the lower portion of the prefabricated cover beam to allow the U-shaped steel bar to be inserted. The height of a pier body is divided into four equal parts, and UHPC, C80, C60 and C40 concrete materials are sequentially used for pouring from bottom to top. By means of the factory segment prefabrication mode, the construction quality is improved, the construction speed is increased, pollution of the site to the environment is reduced, compared with an existing segment prefabrication assembly bridge pier, the advantages of corrugated pipe grouting and tenon core socket type prefabrication assembly bridge piers are comprehensively reserved, and the anti-seismic property of the structure is better than that of equivalent cast-in-place.
本发明公开了一种新型组合式预制拼装桥墩，属于土木建筑与交通运输业桥梁工程技术领域。包括预制底承台、预制的桥墩墩身、预制盖梁、连接承台与墩身的灌浆套筒和榫芯承插的组合结构体系。与盖梁连接的桥墩顶面预留U型钢筋，承台上预留与墩柱灌浆套筒相匹配的UHPC圆柱形承插柱，墩身底部预留与承台榫芯匹配的凹槽。预制盖梁下部预留凹槽以插入U型钢筋。将墩身高度按照四等分，由下至上依次使用UHPC、C80、C60、C40混凝土材料浇筑。本发明通过工厂节段预制的形式，提高施工的质量，提升施工速度，减小现场对环境的污染，与现有的节段预制拼装桥墩相比，综合预留了波纹管灌浆与榫芯承插式预制拼装桥墩的优点，此种结构的抗震性能优于等同现浇。
