UHPC box girder bridge
The invention relates to the technical field of bridge construction, and particularly discloses a UHPC box girder bridge which comprises a pier column and a bridge body, a groove is formed in the top of the pier column, a base is arranged in the groove, a cushion layer is further laid on the top of the pier column, a damping mechanism is arranged in the base, and the damping mechanism comprises two first hydraulic cylinders, a buffering hydraulic cylinder, a movable blocking piece and a pressing assembly. First piston pieces are movably arranged in the first hydraulic cylinders, the pressing assembly is arranged at the opening of the base and connected with the two first piston pieces, the buffering hydraulic cylinder is located between the two first hydraulic cylinders, a channel is formed between the two first hydraulic cylinders and the buffering hydraulic cylinder, and an elastic extrusion piece is arranged at the upper end of the buffering hydraulic cylinder. The movable blocking piece is movably arranged on the channel so as to drive the movable blocking piece to move to open the channel when the pressing assembly presses liquid in the first hydraulic cylinder to flow out, and the box girder bridge can guarantee the stability and damping performance of a bridge according to the passing condition of the bridge floor.
本发明涉及桥梁建筑技术领域，具体公开了一种UHPC箱梁桥，包括墩柱和桥体，墩柱顶部设置有凹槽，凹槽内设有基座，墩柱顶部还铺设有垫层，基座内设有减震机构，减震机构包括第一液压缸、缓冲液压缸、活动挡片和按压组件，第一液压缸有两个，第一液压缸内活动设有第一活塞件，按压组件设于基座的开口处，按压组件与两个第一活塞件连接，缓冲液压缸位于两个第一液压缸之间，两个第一液压缸与缓冲液压缸之间设有通道，缓冲液压缸上端设有弹性挤压件，活动挡片活动设置在通道上，以在按压组件按压第一液压缸内的液体流出时带动活动挡片移动打开通道，本发明的箱梁桥可以根据桥面的通行情况保证桥梁的稳定性和减震性能。
