Swinging extra-large bridge thin-wall hollow high pier and construction technology
The invention provides a swingable extra-large bridge thin-wall hollow high pier which comprises a pier base and a pier column, a machining groove suitable for installing the pier column is formed in the pier base, the pier column comprises a steel plate layer and an FRP layer, the steel plate layer comprises an inner steel plate layer and an outer steel plate layer, and the inner steel plate layer and the outer steel plate layer are arranged in the machining groove. A concrete layer is poured between the inner steel plate layer and the outer steel plate layer, the FRP layer is arranged on the outer side of the outer steel plate layer, and a rubber layer is arranged between the outer steel plate layer and the FRP layer. A transverse steel plate and a longitudinal steel plate are fixedly arranged in the machining groove, the transverse steel plate is fixedly connected with the bottom of the pier column, and a plurality of prestressed steel bars are connected between the longitudinal steel plate and the side face, stretching into the machining groove, of the pier column. The invention further provides a construction process of the swingable thin-wall hollow high pier for the extra-large bridge, and by means of the scheme, the anti-seismic and damping effects of the extra-large bridge can be effectively improved.
本发明提供了一种可摇摆的特大桥梁薄壁空心高墩,包括桥墩底座和桥墩柱,所述桥墩底座上形成有适于安装桥墩柱的加工凹槽,所述桥墩柱包括钢板层以及FRP层,其中,所述钢板层包括内钢板层和外钢板层,且在所述内钢板层和外钢板层之间浇灌有混凝土层,所述FRP层设置于所述外钢板层外侧,且在所述外钢板层和所述FRP层之间设置有橡胶层;所述加工凹槽内固定设置有横向钢板和纵向钢板,所述横向钢板与所述桥墩柱的底部固定连接,所述纵向钢板与所述桥墩柱伸入所述加工凹槽内的侧面之间连接设置有若干个预应力钢筋。本发明还提供了一种可摇摆的特大桥梁薄壁空心高墩的施工工艺,通过本发明方案,可以有效提高特大桥桥梁的抗震和减震效果。
