Fabricated steel-concrete composite structure bridge suitable for mountain environment and construction method
The invention discloses a fabricated steel-concrete composite structure bridge suitable for a mountain environment. The fabricated steel-concrete composite structure bridge comprises a foundation, a steel pipe concrete pier column, a combined pier top cross beam, a steel main beam and a prefabricated bridge deck slab. The concrete-filled steel tube pier column comprises a prefabricated pier column steel shell and concrete poured in the prefabricated pier column steel shell. The combined pier top cross beam comprises a box beam of a prefabricated steel structure and concrete poured in the box beam, the end of the steel main beam and the top end of the prefabricated pier column steel shell are jointly poured in the box beam to form a fixed connection type pier beam force transmission joint, and the top face of the steel main beam and the top face of the box beam which are located on the same horizontal plane form a supporting face. The prefabricated bridge deck slab is laid on a supporting surface formed by the steel main beam and the box beam; the overall stress performance of a traditional steel-concrete combined bridge is improved, the upper assembly component and the lower assembly component are matched in quality, the hoisting weight is small, the number of on-site construction procedures is small, operation is easy, and the method can be well suitable for rapid and high-quality construction of the bridge under the condition that sites such as the mountain environment are limited.
本发明公开了一种适用于山地环境的装配式钢‑混组合结构桥梁，包括基础、钢管混凝土墩柱、组合式墩顶横梁、钢主梁和预制桥面板；钢管混凝土墩柱包括预制墩柱钢壳和在预制墩柱钢壳内浇筑的混凝土；组合式墩顶横梁包括预制钢结构的箱形梁和在箱形梁内浇筑的混凝土，所述钢主梁的端部和预制墩柱钢壳的顶端共同被浇筑在箱形梁内，形成固接式墩梁传力节点，位于同一水平面的钢主梁顶面和箱型梁顶面形成支撑面，所述预制桥面板在钢主梁和箱型梁形成的支撑面上铺设；本发明提高了传统钢混组合桥梁的整体受力性能，上下部装配构件质量匹配且吊装重量较小，现场施工工序较少且易于操作，能较好适用于山地环境等场地受限情况下的桥梁快速和高质量施工。
