真空辅助压浆技术在连续刚构桥中的应用

On application of vacuum aid grouting technique in continuous rigid frame bridge

以牛角坪双线特大桥工程为例,结合真空辅助压浆基本原理,介绍了真空辅助压浆技术在连续刚构桥中的应用,分别阐述了该技术的优越性,施工工艺及注意事项等内容,以期指导同类桥梁工程施工。

Taking the Niujiaoping double-line super-large Bridge as the example, the paper, combining with the basic principle of the vacuum aid grouting, introduces the application of the vacuum aid grouting technique in the continuous rigid frame bridge, and illustrates the advantages, the construction craft and precautions of the technique, so as to direct similar bridge construction.
