T-shaped assembly type rail transit elevated station structure and construction method
The invention belongs to the technical field of rail transit, and particularly relates to a T-shaped assembly type rail transit elevated station structure and a construction method.The T-shaped assembly type rail transit elevated station structure comprises a station foundation and a station platform layer, and the station platform layer is installed on the station foundation; the station platform layer comprises a prefabricated pier column and a prefabricated cover beam, the lower end of the prefabricated pier column is connected with the station foundation through a connecting steel bar, the top of the prefabricated pier column is connected with the prefabricated cover beam through a pier column steel bar, and through the pre-buried connecting condition of the bearing platform, the prefabricated pier column and the prefabricated cover beam, prefabricated assembly of the rail transit elevated station structure is achieved, and the structure stress is met; the construction efficiency is improved; besides, a vertical prestress steel strand penetrates downwards from the top of the prefabricated cover beam and is connected with the anchoring end of the vertical prestress steel strand pre-buried in the bearing platform, and the two stress effects of unbonded vertical prestress and bonded vertical prestress are achieved by selecting whether a protective sleeve is arranged outside the vertical prestress steel strand or not. Reasonable selection can be carried out according to actual construction environments and construction requirements.
本发明属于轨道交通技术领域，尤其涉及一种T字型装配式轨道交通高架车站结构及施工方法，包括车站基础和车站站台层，车站站台层安装在车站基础上；车站站台层包括预制墩柱和预制盖梁，预制墩柱下端通过连接钢筋与车站基础连接，预制墩柱顶部通过墩柱钢筋与预制盖梁连接，通过承台、预制墩柱、预制盖梁预埋连接条件，实现了轨道交通高架车站结构预制拼装，满足结构受力，提高施工效率；另外，由预制盖梁顶部向下穿入竖向预应力钢绞线，与承台内预埋的竖向预应力钢绞线锚固端连接，通过选择是否在竖向预应力钢绞线外设置保护套，达到无粘结竖向预应力和有粘结竖向预应力两种受力效果，可针对实际施工环境及施工要求进行合理选择。
