Abstract:
Application of graded waterproof curtain technology in riprap dams and coarse-grained strata under dynamic water pressure is introduced, and the principle, technology, construction method and waterproof effect are also presented. Through engineering examples, the filling technology of graded dry powder and the splitting grouting technology of third-sequence holes are introduced in detail. Graded waterproof curtain technology has been proved to be effective by engineering, which is suitable to be applied in practice under similar working conditions.
