Summary:The invention discloses an anti-seepage construction technology for connecting a geomembrane on a single anti-seepage wall, and belongs to the technical field of water conservancy and hydropower. S1, filling materials of an underwater part of a cofferdam are thrown and filled; s2, after underwater throwing and filling are completed, in order to improve the stress condition of the diaphragm wall and facilitate the stability of the wall of the slotted hole, the filling materials on the two sides of the slotted hole of the diaphragm wall are subjected to vibroflotation compaction; and S3, diaphragm wall construction is conducted. According to the anti-seepage construction process for connecting the geomembrane on the single anti-seepage wall, the safety and stability of a cofferdam during long-term high-water-level water retaining operation can be ensured, and when a seepage channel exists in the anti-seepage wall, quick plugging can be performed to avoid further development and expansion of dangerous cases, so
