Anti-seepage structure of brine conveying channel
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 dissolves magnesium chloride in the old brine, so that the infiltrated brine is saturated, and the saturated brine cannot flow in a narrow channel, cannot continuously dissolve salt to infiltrate, and particularly cannot dissolve sodium chloride tail salt crystal particles playing a supporting role, so that good anti-seepage and anti-collapse effects can be achieved.
本发明涉输卤渠的防渗漏结构，所述输卤渠包括坝体以及开设在所述坝体表面，沿所述坝体延伸出的基槽构成，其特征在于：还包括尾盐层、粘土层，所述坝体设置在地面上由土石材料夯实制成，横截面呈上小下宽的梯形，所述基槽由所述坝体上表面向下开挖形成，横截面成“U”字状，所述基槽的表面由内向外分别覆盖有尾盐层和粘土层作为防渗层，所述尾盐层由高钠尾盐结晶与老卤制备而成，所述粘土层由粘土压实构成。由于从粘土层下渗的卤水会先溶解老卤中的氯化镁，使得下渗的卤水达到饱和，这些饱和的卤水既不会在窄道中流动、也不会继续溶解盐分而下渗，尤其是不会溶解起到支撑作用的氯化钠尾盐结晶颗粒，因此能起到很好的防渗、防坍塌效果。
