Anti-seepage flexible step spillway

The utility model discloses an anti-seepage flexible step spillway, which relates to the technical field of water conservancy, and is characterized in that an original vertical side slope built by geobags is adjusted and designed into a combined structure of a spillway inclined side slope and a spillway side slope step, so that the flowing water can be better guided, and the spillway can be more efficiently spilled; the backfill soil in the CDASS geobag, the spillway inclined slope and the formed backfill soil of the spillway slope step are all cemented soil mixed with lime, cement and soil, so that the erosion resistance and erosion resistance of the spillway of the soil and the stability of the slope and the discharge chute can be better ensured; the exposed part of the whole spillway issubjected to anti-seepage treatment, so that erosion, permeation and erosion damage of water flow to the dam body are effectively prevented, and the integrity and reliability of the dam body and thespillway are ensured; acco
