Self-resetting and high-energy-consumption assembly type pier and construction method thereof
The invention relates to the technical field of structural engineering, and discloses a self-resetting and high-energy-consumption assembly type pier which comprises a bearing platform body, a pier body, prestressed tendons and energy consumption rods. The upper end face of the bearing platform body is provided with an inwards-concave fixing groove, and the bottom of the pier body is assembled in the fixing groove. The lower connecting section of the pier body extends outwards around the pier body to form a connecting block, and an upper prestressed rib pipeline is reserved on the connecting block; the lower ends of the prestressed tendons are buried in the bearing platform body, and the prestressed tendons are arranged on the upper prestressed tendon pipeline in a penetrating mode. The lower portions of the energy dissipation rods are buried in the bearing platform body, and the upper portions of the energy dissipation rods are located in the lower connecting section. Tensioning prestressed tendons are arranged in the connecting blocks formed in a protruding mode, weakening of the prestressed ducts to the pier body is avoided, and the vertical bearing capacity of the pier body in the prestressed connecting mode is enhanced. And under the tensioning action of the prestressed tendons, the pier body can be automatically reset.
本发明涉及结构工程的技术领域，公开了一种具备自复位与强耗能的装配式桥墩，包括承台本体、桥墩本体、预应力筋和耗能棒；所述承台本体的上端面具有向内凹陷的固定槽，所述桥墩本体的底部装配于所述固定槽中；所述桥墩本体的下部连接段在墩身周围向外延伸形成有连接块，所述连接块预留有上部预应力筋管道；所述预应力筋的下端埋设于所述承台本体中，所述预应力筋穿设于所述上部预应力筋管道；所述耗能棒的下部埋设于所述承台本体中，其上部位于所述下部连接段中。本发明凸出形成的连接块，在其中布置张拉预应力筋，避免了预应力孔道对桥墩本体的削弱，增强了在预应力连接方式中桥墩本体的竖向承载力。预应力筋的张拉作用，使桥墩本体可自动复位。
