Double-column type pier and construction method thereof
The double-column type pier is formed by building prefabricated reinforced concrete members and comprises a bearing platform, pier columns and a cover beam, the two pier columns are arranged on the bearing platform side by side in a spaced mode, and the cover beam is arranged on the two pier columns; at least one set of steel energy dissipation components is arranged between the two pier columns, each set of energy dissipation components comprises a pair of symmetrically-installed pre-buried bracket components and an energy dissipation coupling beam used for middle connection between the pre-buried bracket components, and each pre-buried bracket component comprises a bracket pre-buried section and a bracket exposed section; the bracket embedded section is connected with the pier columns into a whole by pouring and tamping concrete when the pier columns are prefabricated, and the energy consumption coupling beam is connected between the bracket exposed sections of the embedded bracket component after the two pier columns are installed; the invention further provides a construction method. According to the self-resetting prefabricated assembled double-column pier, the overall energy dissipation capacity of the self-resetting prefabricated assembled double-column pier can be remarkably improved, meanwhile, the strength and rigidity of the double-column pier can be improved, pier damage can be greatly reduced when an earthquake or external force impact occurs, and rapid construction and repair are facilitated.
提供一种双柱式桥墩，由预制钢筋混凝土构件搭建而成，包括承台、墩柱、盖梁，承台上面，并列间隔设置有2个墩柱，盖梁设置在2个墩柱上面；2个墩柱之间设置有至少一组钢制的耗能构件，每组耗能构件包括一对对称安装的预埋牛腿构件与用于其中间连接的耗能连梁，其中，预埋牛腿构件包括牛腿预埋段与牛腿外露段，牛腿预埋段在预制墩柱时通过浇捣混凝土与墩柱连接成一体，耗能连梁在2个墩柱安装后连接在预埋牛腿构件的牛腿外露段之间；并提供其建造方法；能够显著提升自复位预制拼装双柱式桥墩的整体耗能能力，同时能够提高双柱式桥墩的强度和刚度，遇到地震或外力撞击时能大大降低桥墩损伤，并且便于快速建造与修复。
