UHPC pipe-SFRRC-GFRP rib combined single column pier and construction method
The invention discloses a UHPC pipe-SFRRC-GFRP bar combined single-column pier and a construction method, and belongs to the technical field of bridge structures, the UHPC pipe-SFRRC-GFRP bar combined single-column pier comprises a bearing platform, embedded steel bars are arranged on the bearing platform, a steel reinforcement cage is fixed to the embedded steel bars, the steel reinforcement cage is sleeved with a plurality of steel pipe columns which are mutually fixed and coaxial, the outer sides of the steel pipe columns are all sleeved with prefabricated UHPC pipe sections, and the prefabricated UHPC pipe sections are arranged on the outer sides of the prefabricated UHPC pipe sections. The adjacent prefabricated UHPC pipe sections are bonded through epoxy resin; sFRRC concrete is poured in the steel pipe column, and common concrete is poured between the steel pipe column and the prefabricated UHPC pipe sections; the pre-embedded steel bars and the steel reinforcement cage adopt GFRP steel bars; according to the combined single column pier, the steel fiber recycled concrete (SFRC), the glass fiber reinforced composite (GFRP) steel bars and the ultra-high performance concrete (UHPC) prefabricated pipe sections are adopted to be combined into the brand new single column pier, and the combined single column pier has the advantages of being excellent in bearing capacity, corrosion resistance, durability and economical and environment-friendly performance.
本发明公开了一种UHPC管‑SFRRC‑GFRP筋的组合独柱墩及施工方法，属于桥梁结构技术领域，包括承台，承台上设置有预埋钢筋，预埋钢筋上固定有钢筋笼，钢筋笼套设有若干节相互固定且同轴线的钢管柱，钢管柱外侧均套设有预制UHPC管节段，相邻的预制UHPC管节段之间通过环氧树脂粘结；钢管柱内部浇筑有SFRRC混凝土，钢管柱与预制UHPC管节段之间浇筑有普通混凝土；预埋钢筋与钢筋笼均采用GFRP钢筋；本发明采用钢纤维再生混凝土(Steel Fiber Reinforced Recycled Concrete,SFRRC)，玻璃纤维增强复合材料(Glass Fiber Reinforced Polymer,GFRP)钢筋，超高性能混凝土(Ultra‑High Performance Concrete,UHPC)预制管节段，组合成一种全新的独柱墩，该组合独柱墩具有优秀的承载力、耐腐蚀性、耐久性、经济环保性。
