虹桥机场东跑道基础二次注浆加固工程实施

On Secondary Grouting Strengthening Project of East Runway Foundation of Hongqiao International Airport

虹桥机场东跑道作为国内道面结构最复杂的跑道,首次在同一跑道下进行二次注浆。介绍了东跑道注浆加固工程主要设计施工方案、施工参数、检测方法、检测标准和注浆检测结果,并对实施过程中存在的问题提出了相应建议,可供类似工程参考。

Being regarded as the most complicated pavement structure in China,east runway of Hongqiao International Airport is made secondary grouting for the first time under the same runway.Several key points of this east runway grouting strengthening project are introduced in this paper including main design construction plan,construction parameters,detection method,detection standard and grouting detection results,etc.Moreover,the corresponding suggestions are proposed aiming to existed problems during the project period,which can be provided for similar projects.
