Prefabricated UHPC railway steel bridge deck rigid waterproof pavement layer and construction method
The invention discloses a prefabricated UHPC railway steel bridge deck rigid waterproof pavement layer and a construction method, and relates to the technical field of railway steel bridge deck protection.The rigid waterproof pavement layer comprises an anti-corrosion coating used for being laid on a steel bridge deck slab; the UHPC waterproof structure layer comprises a plurality of prefabricated UHPC plates arranged according to preset positions, each prefabricated UHPC plate comprises a reinforcing mesh formed by longitudinal reinforcing steel bars and transverse reinforcing steel bars in a staggered mode and concrete plates poured on the reinforcing mesh, a gap is reserved between every two adjacent concrete plates, and the longitudinal reinforcing steel bars and the transverse reinforcing steel bars extend outwards into the gaps. The gaps are staggered, overlapped and fixedly connected, and the gaps are filled with ultra-high performance concrete; the connecting assembly is used for being arranged at the preset position, where the prefabricated UHPC board is installed, of the steel bridge deck slab. And the asphalt waterproof layer is laid on the UHPC waterproof structure layer. The waterproof pavement layer is high in construction speed while having good waterproof performance, and can better realize common stress with the steel bridge deck slab, so that the fatigue of the steel bridge deck slab is reduced.
本发明公开了一种预制UHPC的铁路钢桥面刚性防水铺装层及施工方法，涉及铁路钢桥面防护技术领域，该刚性防水铺装层包括防腐涂层，其用于铺设在钢桥面板上；UHPC防水结构层，包括按预设位置设置的多块预制UHPC板，预制UHPC板包括纵向钢筋和横向钢筋交错设置形成的钢筋网和浇筑在钢筋网上的混凝土板，相邻混凝土板之间留有间隙，纵向钢筋与横向钢筋均向外伸出至间隙内，且在间隙内交错重叠并固定连接，间隙填充有超高性能混凝土；连接组件，其用于设置在钢桥面板上安装预制UHPC板的预设位置；沥青防水层，其铺设在UHPC防水结构层上。该防水铺装层在具有良好的防水性能的同时施工速度快，且可以与钢桥面板较好的实现共同受力，减少钢桥面板的疲劳度。
