高速公路下伏采空区注浆治理效果的检测技术

Grouting Effect in Mined out Region Under Expressway Tested by Boring Method

采空区注浆治理工程质量检测技术是矿区高速公路治理的关键技术之一。以某高速公路采空区注浆治理工程为例,系统分析了高速公路下伏采空区钻探检测的方法与原则,具体分成三个阶段:施工前的钻孔勘察、施工中的钻孔监控以及施工后不同时间的检测,对类似工程有参考意义。

Quality test technology of grouting in mined-out region is one of the important technologies in the expressway treat- ment in mine region. The boring method and its principle are introduced in detail, which one grouting treatment project in mined-out .under expressway is taken as an example. The boring method is divided into three stages~ boring exploration before grouting, controlling during grouting and testing after grouting, which is provided as a reference to similar engineering.
