Damping buffering energy dissipation type bridge anti-collision structure and device
The invention provides a damping buffering energy dissipation type bridge anti-collision structure and device.The damping buffering energy dissipation type bridge anti-collision structure comprises an anti-collision bag body filled with damping media, and an energy dissipation device is arranged on the side, facing a pier, of the anti-collision bag body and communicates with the anti-collision bag body through a valve; the energy dissipater is provided with at least one layer partition plate in the axial direction, and a plurality of damping flow channels are formed in the layer partition plate. According to the structure, flexible buffering of ship collision impact is achieved through the anti-collision bag body, meanwhile, the viscous characteristic of the damping medium is combined, collision kinetic energy is dissipated in the form of internal energy, the overall anti-collision performance is good, and follow-up maintenance of collision accidents is easy.
本发明提供一种阻尼缓冲耗能型桥梁防撞结构及装置，其中阻尼缓冲耗能型桥梁防撞结构包括内部填充有阻尼介质的防撞囊体，所述防撞囊体朝向桥墩的一侧设有消能器，所述消能器通过阀件与所述防撞囊体连通；所述消能器在轴向上设有至少一个层隔板，所述层隔板上开设有多个阻尼流道。该结构利用防撞囊体实现对船撞冲击的柔性缓冲，同时结合阻尼介质的粘滞特性，将撞击动能以内能形式耗散，整体的耐撞性能较好，撞击事故后续的维护简单。
