Anti-seepage construction process for connecting geomembrane on single anti-seepage wall
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 that the later plugging construction has good feasibility, and the construction period is shortened. The method has the characteristics of high construction speed, simplicity, convenience, feasibility and the like, and has important significance on application and development of geomembranes and diaphragm walls.
本发明公开了一种单防渗墙上接土工膜防渗施工工艺，属于水利水电技术领域，S1、进行围堰水下部分填筑料的抛填；S2、水下抛填完成后，为改善防渗墙受力条件，同时有利于开槽孔壁稳定，对防渗墙槽孔两侧填筑料进行振冲密实；S3、进行防渗墙施工。本发明为一种单防渗墙上接土工膜防渗施工工艺，能够确保围堰在长期高水位挡水运行时的安全、稳定，并且当发现防渗墙存在的渗漏通道时，可以进行快速封堵，避免险情进一步发展、扩大，使其后期封堵施工具有良好的可实施性，施工快速、简便易行等特点，对土工膜与防渗墙的应用、发展具有重要意义。
