1 引言 堤防灌浆是改善堤防工程质量的一项重要技术措施。建国后,我省长汀堤防经过多次大规模复堤加固,由于筑堤时淤土块和冻土块未清除或有软弱夹层;部分施工段分界接头不紧密,分层碾压不实等,造成部分堤防局部部位不实,在汛期高水位时堤身出现散浸、渗漏等现象。去冬今春,长汀堤防灌浆工作已在沿江各地全面展开,为合理掌握施工技术,控制堤防灌浆质量,本文主要对常用的劈裂灌浆进行探讨。
1 Introduction Embankment grouting is an important technical measure to improve the quality of dike. After the founding of the People’s Republic of China, the Changting embankment in our province has been reinforced with many large-scale embankments since the silt blocks and permafrost blocks have not been cleared or are weakly intercalated during embankment; some joints in the construction section are not closely connected and layered lamination is not real , Resulting in partial embankment part of the false, high flood in flood season dike dipping, leakage and so on. Winter to spring, Changting dike grouting work has been carried out in all parts of the Yangtze River, in order to properly grasp the construction technology, control of embankment grouting quality, this article mainly on the common split grouting.
