管式静压注浆在高速公路加固台背回填的应用

On application of tubular static pressure grouting in consolidation and back filling behind abutment on expressways

结合高速公路大修应用管式静压注浆方法加固台背回填实例,对管式静压注浆加固机理进行了分析,具体介绍了该项施工工艺的实施过程,总结了现场质量控制要点及注意事项,并指出采用管式静压注浆工艺有效地解决了高速公路的桥头跳车问题。

Combining with the application of the tubular static pressure grouting method to have the consolidation of back filling behind abutment on expressways, the paper analyzes the consolidation mechanism for the tubular static pressure grouting, introduces the implementation process for its construction craft, sums up the.points for the site quality control and precautions, and points out the tubular static pressure grouting can solve the bump at bridge-head on expressways better.
