Corrugated steel bottom plate-crossed steel rib plate-UHPC combined bridge deck and construction method thereof
The invention belongs to the technical field of bridge engineering, and discloses a corrugated steel bottom plate-crossed steel rib plate-UHPC combined bridge deck slab and a construction method thereof.The corrugated steel bottom plate-crossed steel rib plate-UHPC combined bridge deck slab comprises a prefabricated corrugated steel bottom plate, and wave crests and wave troughs of the prefabricated corrugated steel bottom plate are sequentially and alternately arranged in the transverse direction of a bridge deck; crests and troughs of the prefabricated corrugated steel bottom plate extend in the longitudinal direction of the bridge floor, a steel rib plate cross structure is erected on the prefabricated corrugated steel bottom plate, and a reinforcing mesh structure is embedded in the steel rib plate cross structure; an ultra-high performance concrete filling layer is poured in a space formed by the prefabricated corrugated steel bottom plate, the steel rib plate cross structure and the reinforcing mesh structure, and the steel rib plate cross structure and the reinforcing mesh structure are located in the ultra-high performance concrete filling layer; the problems that the orthotropic steel bridge deck is cracked due to fatigue, the asphalt pavement layer of the steel bridge deck is damaged, and the steel-UHPC combined bridge deck is complex in construction, low in speed and the like are solved.
本发明属于桥梁工程技术领域，公开了波形钢底板‑交叉钢肋板‑UHPC组合式桥面板及其施工方法，包括预制波形钢底板，所述预制波形钢底板的波峰和波谷在桥面横向方向上依次交替布置，预制波形钢底板的波峰和波谷在桥面纵向方向上延伸布置，在预制波形钢底板上架设有钢肋板交叉结构，在钢肋板交叉结构上嵌装有钢筋网结构，在预制波形钢底板、钢肋板交叉结构和钢筋网结构形成的空间内浇筑有超高性能混凝土填充层，其中，钢肋板交叉结构和钢筋网结位于超高性能混凝土填充层内部；本发明改善了正交异性钢桥面板疲劳开裂和钢桥面沥青铺装层破坏和钢‑UHPC组合桥面施工复杂、速度慢等问题。
