Embodiment 1
[0030] Such as Figure 1~4 The schematic diagram of the structure of the energy-dissipating assembled pier of the present invention is shown, including a cap 1, a prefabricated assembled pier 2, a joint 3, a damper, a mild steel support 9, a prestressed tendon 10, a shear key 11 and a cover beam 12.
[0031] A plurality of prefabricated assembled piers 2 are vertically arranged on the upper surface of the cap 1, among which four prefabricated assembled piers 2 form a group, replacing one pier in the traditional bridge pier structure, between a group of four prefabricated assembled piers 2 A plurality of dampers are arranged between them, and a cover beam 12 is arranged on the upper surface of the prefabricated assembled pier 2; a pier is divided into a four-legged frame pier composed of four pier columns, which can effectively reduce the section area and increase the size of a single section. Section height, reducing the number of sections for a single pier body.
