赫山区烂泥湖垸资江大堤应急处险加固方案探讨

Discussion on the Reinforcement Plan for Emergency Danger of Zijiang River Levee on Lanni Lake Embankment in Heshan District

论文结合赫山区烂泥湖垸资江大堤近年汛期高洪水位的出险情况,通过实际调查及地勘成果研究,分析了赫山区资江大堤堤防存在的问题,并针对部分堤防不达标的情况提出了整治加固方案。方案主要包括对存在蚁穴的堤身进行蚁穴处理;对堤基出现渗漏的地方针对性地采用水泥土防渗墙、高喷防渗墙以及塑性砼防渗墙三种联合防渗方案;对两水夹堤的堤防进行填塘固基,对老旧涵管进行封堵以及封堵沿线100m范围内的手压井等。

Based on the dangerous situation of high flood level in recent flood season of Zijiang Levee on the Lanni Lake embankment in Heshan District,this paper analyzes the problems existing in Zijiang Levee in Heshan District through the actual investigation and the research of geological prospecting results,and puts forward the reinforcement plan for some levees which fail to meet the standard.The plan mainly includes treating the levee body with ant caves,adopting three combined seepage-proofing plans of cement-soil seepage-proofing wall,high spray seepage-proofing wall and plastic concrete seepage-proofing wall to deal with the seepage of levee foundation,filling the pond solid foundation for the levees of the two water barrier,sealing the old culverts and sealing the hand wells within 100m along the line,and so on.
