Swinging FRP (Fiber Reinforce Plastic) combined thin-wall hollow pier and construction process thereof
The invention provides a swingable FRP combined thin-wall hollow pier which comprises a bearing platform and a pier column suitable for being installed on the bearing platform, and the pier column comprises an FRP fiber layer, a plurality of hollow steel pipes wrapped by the FRP fiber layer and lattice beams. Wherein the outer sides of the hollow steel pipes are fixedly connected through the lattice beams to form a core framework with a concrete containing cavity, and a plurality of shear nails are arranged on the outer sides of the hollow steel pipes; core concrete is poured between the concrete accommodating cavity of the core framework and the FRP fiber layer and between the outer side of the core framework and the FRP fiber layer; a first transverse steel plate is fixed at the bottom of the core framework; a second transverse steel plate suitable for being fixedly connected with the first transverse steel plate is arranged on the bearing platform, and a plurality of prestressed steel bars are connected to the position, outside the range of the pier column, between the first transverse steel plate and the second transverse steel plate. The invention further provides a construction technology of the FRP combined thin-wall hollow pier capable of swinging. According to the scheme, the strain resistance of the pier can be improved, and meanwhile engineering materials are saved.
本发明提供了一种可摇摆的FRP组合薄壁空心桥墩，包括承台和适于安装在所述承台上的墩柱，所述墩柱包括FRP纤维层，以及被所述FRP纤维层包裹的若干个空心钢管、格构梁，其中若干个所述空心钢管的外侧通过所述格构梁固定连接以形成具有混凝土容纳腔的核心骨架，且在所述空心钢管的外侧设置有多个剪力钉；所述核心骨架的混凝土容纳腔以及所述核心骨架外侧与所述FRP纤维层之间浇灌有核心混凝土；所述核心骨架底部固定有第一横向钢板；所述承台上设置有适于与所述第一横向钢板固定连接的第二横向钢板，所述第一横向钢板与第二横向钢板之间在位于所述墩柱的范围外处连接有若干预应力钢筋。本发明还提供了一种可摇摆的FRP组合薄壁空心桥墩的施工工艺。通过本发明方案，可以提高桥墩的抗应变能力，同时节省工程材料。
