The invention relates to an anti-seepage structure of a brine conveying channel, the brine conveying channel comprises a dam body and a foundation trench which is arranged on the surface of the dam body and extends out along the dam body, the anti-seepage structure is characterized by further comprising a tail salt layer and a clay layer, the dam body is arranged on the ground and made of soil and stone materials in a tamping mode, and the cross section of the dam body is in a trapezoid shape with a small upper portion and a wide lower portion; the upper surface of the dam body is excavated downwards to form the foundation trench, the cross section of the foundation trench is in a U shape, the surface of the foundation trench is covered with a tail salt layer and a clay layer from inside to outside to serve as impermeable layers, the tail salt layer is prepared from high-sodium tail salt crystals and old brine, and the clay layer is formed by compacting clay. The brine infiltrated from the clay layer firstly
