下承式提篮拱桥钢管混凝土顶升法压注施工

On lift-up method injection construction of steel pipe concrete of through basket arch bridges

钢管混凝土压注是提篮拱桥的关键工序及质量安全控制重点,从混凝土配合比、工艺流程、施工方法等方面做了详细的阐述,总结了混凝土灌注质量控制要点和检验方法,为今后类似工程提供了参考。

The paper points out the steel pipe concrete injection is the key procedure and main points for the quality and safety control of the basket arch bridge,illustrates the concrete＇s mix proportion,craft procedures,construction methods,and sums up the quality control points and inspection methods for concrete grouting,which has provide some reference for similar engineering in future.
