摘　　要：在对圩堤采用垂直防渗墙进行防渗补强处理时,为防止设备钻杆损坏箱涵结构,钻杆需与箱涵保持安全距离,导致穿堤箱涵存在防渗薄弱区,通过分析穿堤箱涵防渗薄弱区渗漏形成原因,依托鄱阳大塘湖电排站拆除重建工程,提出了用箱涵两侧分层、分幅(左右两幅)涂刷泥浆+三序孔跳孔灌浆的施工方法增大混凝土与填筑土体粘结性,增加穿堤箱涵防渗帷幕薄弱区灌浆成墙效果的穿堤箱涵防渗薄弱区补强处理方法。The culvert passing through the embankment is a hydraulic structure buried beneath the levee,typically prefabricated or cast-in-place reinforced concrete.When vertical impermeable walls are used for seepage prevention and reinforcement treatment of the levee,to prevent drilling rods from damaging the culvert structure,a safe distance must be maintained between the drilling rods and the culvert.This leads to vulnerable seepage areas in the culvert passing through the embankment.By analyzing the causes of seepage formation in the vulnerable seepage areas of the culvert passing through the embankment,a construction method is proposed,which involves applying mud on both sides of the culvert in layers and sections(left and right sections)and injecting grout into three-stage holes to enhance the bond between concrete and backfill soil,thereby increasing the effectiveness of grouting the vulnerable seepage curtain areas of the culvert passing through the embankment.
