Anti-seepage dam panel of hydraulic dam

The utility model provides an anti-seepage hydraulic dam face plate. The anti-seepage hydraulic dam face plate comprises a hydraulic dam body, a mounting hanging ring, a reinforcing bolt, a bottom shaft sleeve, a connecting sleeve assembly, a sand collecting guide cover plate, a rotating roller shaft, a buffering air bag, a dam face plate splicing sealing clamping sleeve assembly, a first supporting rod mounting base, a second supporting rod mounting base and an H-shaped reinforcing steel plate. According to the utility model, the panel insertion blocks are inserted into the concave clamping grooves, so that direct connection and fixation of the hydraulic dam body are facilitated; leakproof rubber strips are glued to the surfaces of the intersections of the panel insertion blocks and the inwards-concave clamping grooves, so that further sealing of connecting gaps is facilitated; in addition, under the action of an upper steel plate, a lower steel plate, a transverse reinforcement cage, longitudinal reinforcin
