摘要
固海扬水灌区渠道土质多为湿陷性黄土,由于渠道老化现象严重,渠道输水渗漏量大,给渠道的正常运行带来极大的安全隐患.探讨劈裂灌浆技术加固渠道机理的基础上,以固海扬水灌区第5干渠为例,介绍了在湿陷性黄土地区渠道防渗加固处理中采用劈裂灌浆的施工方法、施工工艺以及经劈裂灌浆处理后渠道的防渗效果,为类似渠道的排险加固和防渗处理提供了一项新的处理技术.
Most of the canal soil in Guhai Pumping Irrigation Area is collapsible loess. Because of serious aging, there was a great deal of seepage when the canals transported water, which brought great potential danger for common run of the canal. Taking the fifth trunk canal as example, on the basis of discussion on the mechanism of split grouting technique for canal consolidation, the construction methods and techniques of split grouting for canal impervious consolidation in collapsible loess area as well as impervious effects after using split grouting technique were introduced, which provided a new technique of removing danger, consolidation and impervious treatment for the similar canals.
