Reservoir composite geotechnical dam body anti-seepage structure and construction method thereof

The invention discloses a reservoir composite geotechnical dam body anti-seepage structure and a construction method thereof.The reservoir composite geotechnical dam body anti-seepage structure comprises a dam body mechanism, a force eliminating mechanism arranged on the left side of the dam body mechanism and an anti-impact mechanism arranged on the surface of the dam body mechanism, and the anti-impact mechanism comprises a protective reinforced cement layer; a clay layer is fixedly connected to the surface of the protective reinforced cement layer, a concrete layer is fixedly connected to the surface of the clay layer, and pouring pipes are arranged on the two sides of the top of the concrete layer. By arranging the impact-resistant mechanism, the dam body mechanism can be protected, water impact is blocked through the concrete layer, then water is conveyed through the water conveying mechanism, the situation that water flows out of the top of the dam body mechanism to form flood is avoided, the slope surf
