Energy consumption device capable of resisting impact of chippings and rolling stones
The invention discloses an energy consumption device capable of resisting impact of chippings and rolling stones, and relates to the technical field of pier protection. Comprising an inner cylinder body, a middle cylinder body and an outer cylinder body which are sequentially arranged on the outer side of a bridge pier column in a sleeving mode from inside to outside, an anti-collision unit is arranged on the outer side of the outer cylinder body, a rubber air spring is arranged in an inner cavity of the outer cylinder body, a damping alloy energy dissipation structure is arranged in an inner cavity of the middle cylinder body, and the inner cavity of the inner cylinder body is filled with concrete. The outer cylinder body comprises a plurality of annular steel sleeves which are mutually spliced in the height direction of the bridge pier column, and the anti-collision unit comprises a plurality of anti-collision blocks which are uniformly distributed in the circumferential direction of the annular steel sleeves. Through the anti-collision units, the rubber air springs, the damping alloy energy dissipation structures and the inner barrel filled with the concrete, step-by-step energy dissipation is conducted, falling stone impact energy is reduced to the maximum extent, the impact effect of chippings and falling stones on the pier structure is reduced, and protection of the bridge pier column is achieved.
本发明公开了一种可抵抗碎屑滚石冲击的耗能装置，涉及桥墩防护技术领域。包括由内至外依次套设于桥梁墩柱外侧的内筒体、中间筒体和外筒体，所述外筒体的外侧设有防撞单元，所述外筒体的内腔设有橡胶空气弹簧，所述中间筒体的内腔设有阻尼合金耗能结构，所述内筒体的内腔填充有混凝土，所述外筒体包括多个沿桥梁墩柱高度方向相互拼接的环形钢套筒，所述防撞单元包括多个沿所述环形钢套筒的周向均匀分布的防撞块。本发明通过防撞单元、橡胶空气弹簧、阻尼合金耗能结构以及填充有混凝土的内筒体进行逐级耗能，最大限度减小落石冲击能量，降低碎屑落石对桥墩结构的冲击作用，实现对桥梁墩柱的保护。
