Railway assembled hollow pier and construction method thereof
The embodiment of the invention relates to the technical field of railway pier construction, and especially relates to a railway assembled hollow pier and a construction method thereof. The railway assembled hollow pier comprises a bearing platform, standard pier stud sections, pier top pier stud sections and padstones; the bearing platform and the padstones are both manufactured by in-situ casting; the pier top pier stud sections and the standard pier stud sections are all prefabricated parts; the standard pier stud sections are of hollow tubular structures; a self-locking anchorage device fixing end, a steel strand corrugated pipe and an embedded steel bar are embedded in the bearing platform; the bearing platform, the standard pier stud sections and the pier top pier stud sections are assembled and positioned through a plurality of concave-convex shear keys; and the top ends of the prestress steel strands are tensioned on the tops of the pier top pier stud sections, and the guide heads at the bottom ends of the prestress steel strands are fixedly connected with the self-locking anchorage device fixing ends in a self-locking mode. The railway assembled hollow pier can meet the rigidity design requirement of a railway bridge, the light design concept is achieved, all components are in precise butt joint, the assembling reliability is achieved, and the construction period is shortened.
本申请实施例涉及铁路桥墩建造技术领域，具体地，涉及一种铁路拼装空心桥墩及其施工方法。铁路拼装空心桥墩包括承台、标准墩柱节段、墩顶墩柱节段以及垫石；承台和垫石均为现场浇筑制成；墩顶墩柱节段和标准墩柱节段均为预制构件；标准墩柱节段为空心管状结构；承台内预埋有自锁式锚具固定端、钢绞线波纹管以及预埋钢筋；承台、标准墩柱节段和墩顶墩柱节段之间均通过多个凹凸剪力键进行装配定位；预应力钢绞线的顶端张紧于墩顶墩柱节段的顶部、且底端的导向头与自锁式锚具固定端之间自锁固定连接。该铁路拼装空心桥墩能够满足铁路桥梁的刚度设计要求，并实现了轻型化设计理念、各个构件之间的精准对接、装配的可靠性和缩短施工工期。
