Bridge damping structure suitable for pile group foundation
A disclosed bridge damping structure suitable for a pile group foundation comprises a pier, a bearing platform is fixedly poured at the bottom of the pier, and a pressure-bearing steel plate corresponding to a pile foundation at the bottom of the bearing platform is pre-buried in the bearing platform; an outer steel casing with a downward casing opening is fixedly arranged at the bottom end of the pressure-bearing steel plate; the bottom of the outer steel casing penetrates out of the bottom end of the bearing platform, and the top end of the pile foundation is covered with the outer steel casing; the top of the pile foundation is fixedly provided with an inner steel casing wrapping the pile foundation; and the inner steel casing is a cylinder body without a bottom face, and a radial gap is formed between the side wall of the inner steel casing and the side wall of the outer steel casing. According to the damping structure, rigid connection between the bearing platform and the pile foundation can be avoided, the damping effect is good, and the damping structure is suitable for the pile group foundation in the bridge.
本发明公开了一种适用于群桩基础的桥梁减震结构，包括桥墩，所述桥墩的底部固定浇筑有承台，承台内预埋有与承台底部桩基础相对应的承压钢板；所述承压钢板底端固定设置有筒口朝下的外钢护筒；所述外钢护筒底部穿出承台底端且各外钢护筒罩在桩基础顶端；所述桩基础的顶部固定设置有包在桩基础外部的内钢护筒；所述内钢护筒为无底面的筒体，内钢护筒与外钢护筒的侧壁之间具有径向间隙。本发明旨在提供一种能避免承台与桩基础的刚性连接，减震效果好，适用于桥梁中群桩基础的减震结构。
