Steel cover beam gate-type pier structure
The invention belongs to the field of design and construction of bridge engineering, and particularly relates to a steel cover beam gate-type pier structure. The structure comprises a steel cover beam, a bearing platform, a pier column and a prestressed steel beam system, and the pier column comprises a concrete pier column arranged on the bearing platform; the steel pier column is connected to the lower portion of the steel cover beam, and a prestressed steel cable anchor chamber is formed in the steel pier column; the steel-concrete combined section is used for connecting the steel pier column and the concrete pier column; the prestressed steel beam system comprises a fixed end anchoring assembly arranged in the bearing platform; the tensioning end anchoring assembly is arranged in the steel pier column, and the tensioning end anchoring assembly is located on the outer side of the prestressed steel beam anchoring chamber cavity; one end of the prestressed steel beam extends into the bearing platform to be connected with the fixed end anchoring assembly, and the other end of the prestressed steel beam penetrates through the concrete pier column, the steel-concrete combined section and the prestressed steel beam anchoring chamber to be connected with the tensioning end anchoring assembly; the steel cover beam and the pier column are prefabricated first and then assembled on site. The structure provided by the invention is beneficial to ensuring stable connection of the pier column and the bearing platform, and the influence on the existing operation line can be reduced.
本发明属于桥梁工程的设计与施工领域，具体涉及一种钢盖梁门式墩结构。本发明包括钢盖梁、承台、墩柱和预应力钢束系统，墩柱包括混凝土墩柱，设置于承台上；钢墩柱，连接于钢盖梁下方，钢墩柱内设有预应力钢束锚室腔；及钢混结合段，用于连接钢墩柱和混凝土墩柱；预应力钢束系统包括固定端锚固组件，设置于承台内；张拉端锚固组件，设置于钢墩柱内，张拉端锚固组件位于预应力钢束锚室腔外侧；及预应力钢束，预应力钢束的一端伸入承台内与固定端锚固组件相连，另一端贯穿混凝土墩柱、钢混结合段和预应力钢束锚室腔后与张拉端锚固组件相连；钢盖梁和墩柱均采用先预制后现场拼装的方式。本发明所提供的结构有利于保证墩柱和承台的稳定连接，能够降低对既有营运线的影响。
