谈公路路基下伏采空区注浆处治方法

Discussion on the grouting treatment method of highway sub-grade underlying gob

通过分析某高速公路路基跨越采空区的地质情况及分布特征,提出了注浆处治设计方案,探讨了注浆处治的原则及处治范围,从注浆孔布置、浆液选取、注浆参数等方面,阐述了注浆处治的具体设计内容,结果表明,该采空区采用注浆处治方法达到了良好的治理效果。

Through the analysis on the geological conditions and distribution characteristics of a highway sub-grade across gob,this paper put forward the grouting treatment design scheme,discussed the principle and treatment scope of grouting treatment,from grouting hole layout,slurry selection,grouting parameters and other aspects,elaborated the specific design contents of grouting treatment,the results show that the gob achieved good treatment effect using this grouting treatment method.
