Metamaterial concrete filled steel tube pier and construction method
The invention discloses a metamaterial concrete filled steel tube pier and a construction method, and belongs to the technical field of bridge seismic mitigation and isolation. The technical problem that an existing concrete filled steel tube pier is poor in shock absorption and isolation effect is solved. According to the technical scheme, the metamaterial concrete filled steel tube pier comprises a pier column, the pier column is placed above a bearing platform and below a prefabricated cover beam, and the pier column sequentially comprises a prestressed tendon, an inner concrete layer, a rubber tube, an outer concrete layer and a main steel tube from inside to outside along the radial section. Compared with a traditional concrete filled steel tube pier, the concrete filled steel tube pier has the advantages that the concrete filled steel tube pier is composed of multiple layers of materials, each layer has different physical properties and structures, multiple reflection, interference and scattering effects can be achieved, and the concrete filled steel tube pier has a better shock absorption and isolation effect and higher bearing capacity; and meanwhile, the internal structure is more compact, and the concrete pouring amount is reduced, so that the construction time is shortened, and the construction cost is reduced.
本发明公开了一种超材料钢管混凝土桥墩及施工方法，属于桥梁减隔震技术领域。解决了现有钢管混凝土桥墩减隔震效果不佳的技术问题。其技术方案为：该超材料钢管混凝土桥墩包括墩柱，所述墩柱放置于承台的上方，墩柱放置于预制盖梁的下方，墩柱沿径向截面上自内部而外依次包括预应力筋、内混凝土层、橡胶管、外混凝土层、主要钢管。本发明的有益效果为：与传统的钢管混凝土桥墩相比，由多个层次的材料组成，每个层次都具有不同的物理性质和结构，可以实现多重反射、干涉和散射效应，具有更好的减隔震效果，也更具有承载能力；同时，内部结构更为紧凑，且混凝土浇筑量减少，从而使施工时间和成本较少。
