多跨连续板桥桥面混凝土的浇筑要点

Important points of deck concrete casting of continuous plate girder

采用满堂支架进行多跨连续板桥梁的施工 ,桥面板混凝土的浇筑、梁板位移量的确定以及预拱度的设置是决定工程质量的关键因素 ,为了确保工程的施工质量 ,文章提出了施工期采用预压荷载消除支架的非弹性变形和连续一次浇筑大体积梁板混凝土的技术保障措施 ,经实践证明 ,这些方法是有效和合理的。

In the construction of continuous plat girder on flsaework,the deck casting,the calculation of beam deviation and the precast arch setting are the main factors determining the quality of the technology.During the period of construction, pre compressive load is used to compete the falsework's non elastic deformity and continuous casting of the whole huge concrete is made. The methods are valid and reasonable in pratice.
