公路采空区注浆处治工程属于地下隐蔽工程处治,而注浆处治质量的效果直接影响公路运营期的安全。文中以荣成~乌海高速公路十七沟~大饭铺段采空区注浆质量检测工程为例,主要介绍了瞬变电磁法在采空区注浆质量检测工程中的应用,介绍了其在采空区注浆质量检测工作的前提条件、工作方法、检测成果分析等;利用钻探和孔内波速测试对物探成果进行验证。结果表明,瞬变电磁法可有效探测采空区注浆处治质量,其检测结果准确。瞬变电磁法可快速高效地对整个工区进行整个面上的检测;钻探和孔内波速测试对代表点或异常点进行检测,是对瞬变电磁法检测结果的验证和补充。点面结合的检测方法有效地避免了以往以点代面检测方法的弊端。
Grouting treatment of road gobs belongs to underground hidden engineering treatment, and the effect of grouting treatment quality directly affects the safety of highway operation period. In this paper, Rongcheng ~ Wuhai Expressway Shitougou ~ Dafanpu gob grouting quality testing project, for example, mainly introduces the transient electromagnetic method in goaf grouting quality testing project application, introduced its The preconditions, working methods and test result analysis of grouting quality testing in goaf are verified. The results of geophysical exploration are verified by drilling and in-hole wave velocity test. The results show that the transient electromagnetic method can effectively detect the grouting quality of goaf, and the detection results are accurate. Transient electromagnetic method can quickly and efficiently detect the entire work area on the surface; drilling and wave velocity testing of the representative points or abnormal points for the detection of transient electromagnetic test results to verify and supplement. Dot-surface detection method effectively avoids the drawbacks of point-by-point detection methods in the past.
