Assembled hollow pier and construction method thereof
The invention relates to bridge engineering, in particular to an assembled hollow pier and a construction method thereof. The assembled hollow pier comprises a bearing platform arranged at the lower end of the hollow pier; a hollow pier body; the cover beam is arranged at the upper end of the hollow pier body; the hollow pier body is mainly formed by splicing hollow pier units. The hollow pier further comprises prestressed reinforcements; the upper ends of the prestressed reinforcements are fixedly connected with the bent cap, and the lower ends are fixedly connected below or on the bearing platform. The hollow pier unit includes: an insertion portion provided at one end of the unit body; and the access part is arranged at one end of the collar of the unit body. Shear keys protruding out of the hollow pier units are distributed on the insertion parts. Shear grooves corresponding to the shear keys are distributed in the access part. According to the assembled hollow pier, the prestressed steel bars and the shear keys are arranged, so that the assembled hollow pier not only has good self-resetting capacity and energy dissipation capacity, but also has high shear resistance and torsion resistance.
本发明涉及桥梁工程，特别设计一种拼装式空心墩及其施工方法，拼装式空心墩包括：承台，该承台设置于空心墩的下端；空心墩主体；盖梁，设置于空心墩主体上端；空心墩主体主要由空心墩单元拼接而成；空心墩还包括预应力钢筋；预应力钢筋上端与盖梁固定连接，下端固结于承台下方或承台上。空心墩单元包括：插入部，该拼装部设置于单元主体的一端；接入部，该接入部设置于单元主体的领一端。插入部上分布有向空心墩单元外凸出的剪力键；接入部上分布有与剪力键对应的剪力槽。本发明的拼装式空心墩通过设置上述的预应力钢筋和上述剪力键的设置，使本拼装式空心墩不仅具有良好自复位能力、耗能能力又具有较强抗剪切和扭转能力。
