Management and protection-free integrated silt dam and mixture mixing process thereof

The invention provides a management and protection-free integrated silt dam and a mixture mixing process thereof. The silt dam comprises a homogeneous earth dam body and a protective layer arranged on the homogeneous earth dam body; the protective layer comprises an upstream slope protection layer arranged on the surface of an upstream dam slope of the homogeneous earth dam body, a downstream slope protection layer arranged on the surface of a downstream dam slope of the homogeneous earth dam body and a mixture layer arranged on the dam top of the homogeneous earth dam body, and the mixture layer, the upstream slope protection layer and the downstream slope protection layer are connected into a whole; and a plurality of layers of drainage blind pipes are embedded in the homogeneous earth dam body at intervals, and pipe openings of the drainage blind pipes penetrate through and extend out of the downstream slope protection layer. According to the silt dam, the anti-scouring capacity of the upstream dam slope a
