Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4The utility model provides a technical solution: an anti-seepage slope protection structure of an earth-rock dam, comprising a dam body 1 and a core wall 2 arranged in the dam body 1, a slope protection 3 is arranged at the outer end of the dam body 1, and anti-collision parts are arranged between the slope protection 3, and a buffer is arranged at the lower end of the slope protection 3 located outside the dam body 1, and an anti-seepage composite membrane 4 is arranged at the lower ends of the slope protection 3 and the buffer, and the anti-seepage composite membrane 4 extends from the bottom end of the dam body 1 to the top end of the dam body 1, and an ecological soil layer 8 is filled between the anti-seepage composite membrane 4 and the slope protection 3; anti-seepage is performed on the dam body 1 through the anti-seepage composite membrane 4, and the slope protection 3 is arranged on the anti-seepage composite membrane 4, and the slope protection 3 is spliced ​​with each other, and the impact of water on the dam body 1 can be slowed down by the anti-collision parts, and the impact of water on the shore can be further slowed down by the buffer, thereby preventing water from seeping into the dam body 1; the anti-collision parts include: connecting stone bars 9, the outer ends of the connecting stone bars 9 are arc-shaped, and the connecting stone bars 9 are arc-shaped. The outer end of the connecting stone bar 9 is fixedly connected with a stone column 10, which is arranged in a V shape and is vertically distributed in pairs; the connecting stone bar 9 is located between the connection parts of the slope protection 3, and the stone column 10 is fixed at the outer end of the connecting stone bar 9, which is arranged in a cone shape and is vertically arranged. The water seepage at the connection part of the slope protection 3 can be reduced by connecting the stone bar 9, and the force of water impact can be slowed down by the stone column 10, thereby avoiding impact on the ecological soil layer 8 inside the slope protection 3; the buffer component includes: a buffer body 5, the buffer body 5 is matched and fitted with the anti-seepage composite membrane 4, and a buffer groove 6 is opened at the outer end of the buffer body 5, and the opening of the buffer groove 6 is tilted downward; the buffer body 5 is fixed to the lower end of the slope protection 3, and the dam body 1 is protected from the impact of water flow by the buffer body 5 when the water level is low. The buffer groove 6 opened at the lower end of the buffer body 5 can block the impact of water flow through the buffer groove 6 tilted downward.

When the water level is low, the anti-slip strip 7 fixed on the buffer body 5 can prevent the maintenance personnel from slipping when walking. The protruding anti-slip strip 7 increases the contact area with the maintenance personnel's footsteps, thereby improving the stability during maintenance walking.
