Concrete bridge deck composite structure bridge and construction method thereof
The invention relates to the technical field of bridge construction, in particular to a concrete bridge deck composite structure bridge and a construction method thereof. The steel bridge deck is adopted for the lower-layer railway bridge deck, and the prestressed concrete bridge deck is adopted for the upper-layer highway bridge deck, so that the technical problems that the steel bridge deck adopted for the upper-layer bridge deck is poor in economy and prone to fatigue failure are solved. The concrete bridge deck slabs are prefabricated and cast-in-place in a combined mode, most bridge deck slabs are prefabricated in a blocking mode, the quality of the concrete bridge deck slabs is guaranteed, after the bridge deck slabs are hoisted in place, cast-in-place connection between the bridge deck slabs and between the bridge deck slabs and a steel structure is conducted, the transportation and installation construction difficulty of the bridge deck slabs can be reduced, construction is convenient, and the construction efficiency is improved, and construction cost is saved.
本发明涉及桥梁施工技术领域，具体而言，涉及一种混凝土桥面板组合结构桥梁及其施工方法。本发明通过下层铁路桥面采用钢桥面板，上层公路桥面采用预应力混凝土桥面板，解决了上层桥面板采用钢桥面板经济性较差，且容易出现疲劳破坏的技术难题。混凝土桥面板采用预制和现浇相结合的形式，大部分桥面板采用分块预制，保证混凝土桥面板的质量，桥面板吊装就位后，进行桥面板之间及桥面板和钢结构之间的现浇连接，可以减少桥面板的运输和安装施工难度，便于施工，提高施工效率，节省施工成本。
