Swinging thin-wall hollow high pier structure and construction method thereof
The invention provides a swingable thin-wall hollow high pier structure and relates to the technical field of bridge engineering, the swingable thin-wall hollow high pier structure comprises a pier base and a pier body, the pier base is fixed through a concrete foundation and comprises a lower steel plate, an upper steel plate and low-yield-point steel plates arranged between the upper steel plate and the lower steel plate, and the low-yield-point steel plates are arranged at the two ends of the upper steel plate and the two ends of the lower steel plate; the middle part between the upper steel plate and the lower steel plate is suspended to form a deformation space; the pier body is fixed to the pier base and comprises an FRP layer and a rubber layer attached to the inner side of the FRP layer, a cavity is defined by the FRP layer, a supporting steel plate is arranged in the cavity and divides the cavity into at least two areas, a steel pipe is arranged in at least one area, the supporting steel plate and the steel pipe are both welded and fixed to an upper steel plate, a hollow layer is formed in the steel pipe, and the rubber layer is attached to the inner side of the FRP layer. A concrete layer is arranged from the inner wall of the cavity to the outer side of the steel Therefore, the problems that an existing bridge pier steel pipe is prone to corrosion and poor in overall bearing capacity when pressed are solved. The invention further provides a construction method of the swingable thin-wall hollow high pier structure.
本发明提供了一种可摇摆的薄壁空心高墩结构，涉及桥梁工程技术领域，包括墩座和墩身，其中，墩座通过混凝土基础固定，包括下钢板、上钢板以及配置在上、下钢板之间的低屈服点钢板，低屈服点钢板置于上、下钢板的两端，以使上、下钢板之间的中部悬空形成变形空间；墩身与墩座固定，包括FRP层以及贴合FRP层内侧配置的橡胶层，FRP层围合形成空腔，空腔内置有支撑钢板，支撑钢板将空腔至少分隔为两个区域，至少其中一个区域内安置有钢管，支撑钢板以及钢管均与上钢板焊接固定，钢管内部形成空心层，空腔内壁至钢管外侧设有混凝土层。从而解决现有桥墩钢管容易锈蚀且在受压时整体承载力不佳的问题。本申请另提供一种可摇摆的薄壁空心高墩结构的施工方法。
