Bridge deck rabbet wet joint connecting structure and construction method thereof
The invention discloses a bridge deck rabbet wet joint connecting structure and a construction method thereof, two adjacent prefabricated concrete beams are connected through a reserved UHPC wet joint, and ultra-high performance concrete is poured in the UHPC wet joint; a prestressed duct is reserved in a flange plate of the prefabricated concrete beam, a prestressed steel strand is arranged in the prestressed duct, and clamping piece anchorage devices are embedded in the two sides of the prestressed duct. The method has the characteristics of easiness in industrialized production, small field pouring amount, high construction speed, high wet joint quality, small influence on construction field traffic and surrounding environment and the like.
本发明公开了一种桥面板企口湿接缝连接结构及其施工方法，相邻两个预制混凝土梁之间通过预留的UHPC湿接缝连接，UHPC湿接缝内浇筑超高性能混凝土；预制混凝土梁的翼缘板内部预留有预应力孔道，预应力孔道内设置有预应力钢绞线，预应力孔道的两侧预埋有夹片锚具。本发明具有易于工厂化生产，现场浇筑量少，施工速度快，湿接缝质量高，对施工现场交通以及周围环境影响小等特点。
